Water Hybrid Engine 0.1 1
An engine converts the chemical energy of fuel into mechanical work by rotating a shaft
(crank shaft) via a piston and connecting rod. In older times a lot of motorcycle engines were
based on the 2 Stroke technologies. But due to recent Pollution norms and the maintenance
cost and low average of 2 stroke engines have led to the switch over to new age 4 Stroke
engines making motorcycles highly efficient and green.
Many people claimed the invention of the internal combustion engine in the 1860's, but only
one has the patent on the four stroke operating sequence. In 1867, Nikolaus August Otto, a
German engineer, developed the four-stroke "Otto" cycle, which is widely used in
transportation even today.
1.1 Four Stroke Engine.
The four stroke engine is probably the most common engine type now a day. It powers
almost all cars and trucks. Four stoke engine is internal combustion engine. An internal
combustion engine is any engine that operates by burning its fuel inside the engine. In
contrast an external combustion engine burns its fuel outside the engine like in steam engine.
In 4 stroke engine an explosive mixture is drawn into the cylinder on the first stroke and is
compressed and ignited on the second stroke; work is done on the third stroke and the
products of combustion are exhausted on the fourth stroke.

INTRODUCTION
Water Hybrid Engine 0.1 2
1.1.1 Mechanism of Four Stroke Engine.
There are four movements, or strokes, of the piston before the entire engine firing sequence is
repeated. The four strokes are described below.
Intake stroke
Combustion stroke
Power stroke
Exhaust stroke
1.1.1.1 Intake stroke:
The engine cycle begins with the intake stroke as the piston is pulled towards the crankshaft.
During the intake stroke draws a fresh charge of vaporized fuel/air mixture. Piston moves
from top dead centre (TDC) to bottom dead centre (BDC) completing one stroke. A poppet
intake valve can serve the purpose, it is drawn open by the vacuum produced by the intake
stroke. Some early engines worked this way; however, most modern engines incorporate an
extra cam/lifter arrangement exhaust valve is held shut by a spring.
1.1.1.2 Compression stroke:
With both valves closed, the combination of the cylinder and combustion chamber form a
completely closed vessel containing the fuel/air mixture. As the piston is pushed away from
shaft toward top dead center (TDC), the volume is reduced and the fuel/air mixture is
compressed during the compression stroke. During the compression, no heat is transferred to
the fuel/air mixture. As the volume is decreased because of the piston's motion, the pressure
in the gas is increased, as described by the laws of thermodynamics. To produce the increased
pressure, we have to do work on the mixture, just as you have to do work to inflate a bicycle
tire using a pump. During the compression stroke, the electrical contact is kept opened. When
the volume is the smallest, and the pressure the highest as shown in the figure, the contact is
closed, and a current of electricity flows through the plug. Thus ignition occurs at the end of
this stroke.
1.1.1.3 Power stroke:
Rapid combustion of the fuel releases heat, and produces exhaust gases in the combustion
chamber. Because the intake and exhaust valves are closed, the combustion of the fuel takes
place in a totally enclosed (and nearly constant volume) vessel. The combustion increases the
temperature of the exhaust gases, any residual air in the combustion chamber, and the
combustion chamber itself. From the ideal gas law, the increased temperature of the gases
also produces an increased pressure in the combustion chamber. The high pressure of the
gases acts on the face of the piston and cause the piston to move towards the shaft and to
bottom dead center. This initiates the power stroke. Unlike the compression stroke, the hot
gas does work on the piston during the power stroke. The force on the piston is transmitted by
Water Hybrid Engine 0.1 3
the piston rod to the crankshaft, where the linear motion of the piston is converted to angular
motion of the crankshaft.
The work done on the piston is then used to turn the shaft, and the propellers, and to
compress the gases in the neighbouring cylinder's compression stroke. During the power
stroke, the volume occupied by the gases is increased because of the piston motion and no
heat is transferred to the fuel/air mixture. As the volume is increased because of the piston's
motion, the pressure and temperature of the gas are decreased.
1.1.1.4 Exhaust stroke:
The exhaust valve is opened and the piston travels back up expelling the exhaust gases
through the exhaust valve. At the top of this stroke the exhaust valve is closed. This process
is then repeated.
Figure 1.2 The four stroke cycle.
Water Hybrid Engine 0.1 4
1.1.2 Features of Four Stroke Engine.
Important features of internal combustion four stroke engines are as under.
1.1.2.1 More torque.
This is the most important reasons why people choose a 4-stroke engine. The two-stroke
boasts its speed and power, but the four-stroke shows extra torque. It is more reliable and
quitter.
1.1.2.2 Last longer.
Four stroke engines last longer and use much, much less oil. Compared to two-stroke
engines, the four stroke engine is durable for use. The more times an engine goes around, the
quicker it will wear out. As 2-strokes must rev to very high RPM to make any power, most
applications using them are geared toward maintaining that RPM. Thus, they can’t live as
long as four-stroke engine.
1.1.2.3 Run much cleaner than 2 strokes.
A 2 stroke makes a lot of exhaust smoke because it burns oil mixed with fuel. On the
contrary, four-stroke engines have a dedicated oiling system that’s kept largely separate from
the combustion chamber, which help to ensure that the only thing burning in the engine is
gasoline.
1.1.2.4 More efficient use of gas.
If you have picked up both of them, you may obviously realize the problem. The intake and
exhaust accounted 360 °crank angle, the exhaust top dead center the piston upward, the
residual gas is exhaust forcibly. When a mixture of fuel and air is forced by atmospheric
pressure into the cylinder, the piston down to the intake bottom dead center, the incoming
fresh mixture almost combust. Substantially, there is no wasted fresh mixture. However, for
two-stroke engine, the fresh mixture is escaping with exhaust gases during exhaust stroke.
1.1.3 Application of Four Stroke Engine.
Four stroke engines are used in automobile vehicle like car, bike, etc.
Four stroke engines are also used in aircraft and ships.
It is also used power generation unit as power generator.

1.2 Water Hybrid Engine.
Figure 1.3 Water Hybrid Engine.
Water hybrid engine is first ever developed four stroke engine, which is design to works on
the mixture of petrol and unsaturated water steam. In this typical engine petrol and steam is
allowed to enter into the engine’s cylinder in the first stroke of four stroke engine through
inlet valve, both petrol and steam is compressed TDC (Top Dead Center) of engine cylinder
and combustion is held in cylinder with help spark plug, which expand the volume of the
petrol and steam, results in the pressure which is applying on the piston head and push it to
BDC (Bottom Dead Center) of engine cylinder, hence power stroke is obtain. And at the
fourth and the final stroke exhaust gases are removed out from the cylinder through outlet
Water Hybrid Engine 0.1 6
valve. Due to this consumption of petrol is reduced and equal proportion of steam is used in
this engine.
Thus due to this unique modification in engine, higher fuel efficiency is obtain, which also
reduces the pollutant substance in exhaust gas, which reduces pollution in air. This water
hybrid engine is also economical in use as well as eco friendly.

2.1 Problem Identification.
Every internal combustion engine are developed to attain maximum efficiency, and to
generate maximum power out of less input, in all internal combustion engine fuel + air is
injected/sucked in the combustion chamber and a spark plug provide ignition in combustion
chamber which burn the fuel inside the combustion chamber, and power is generated through
piston and crank shaft.
But in order to generate power, fuel consumption is more in IC engine, which is not
economical to use. Hence the scarcity of fossil fuel is leading to its extinction, which may
lead to hindrance in power production in future, and for automobile industry.
Most of the automobile vehicles are working on petroleum fuel like petrol, diesel etc. and
with the increasing demand of petrol vehicle, consumption of petrol has increased. So there is
need of alternative fuels which can replace the requirement of petrol worldwide. Alternative
fuels like CNG and LPG are taken into practice.
2.1.1 Alternative Fuel.
There is scope of many other types of fuel in future like
1) Hydrogen gas:
Hydrogen is an emission less fuel. The by product of hydrogen burning is water, although
some mono-nitrogen oxides NOx are produced when hydrogen is burned with air.
2) HCNG:
HCNG (or H2CNG) is a mixture of compressed natural gas and 4-9 percent hydrogen by
energy.
3) Liquid Nitrogen:
Liquid nitrogen is another type of emission less fuel.
4) Biodiesel:
Biodiesel is an eco-friendly fuel that can be made from animal fats, algae, or from recycled
vegetable oils like those used by restaurants to cook up French fries and other greasy goodies.

PURPOSE OF DEVELOPMENT
Water Hybrid Engine 0.1 8
5) Ethanol:
Ethanol is another popular alternative fuel that is usually made from fibrous materials like
wood chips or from the starch or sugar found in common crops like corn. Ethanol burns
cleaner than gasoline while reducing greenhouse gases.
6) Electricity:
Electricity isn't new, but modern science has found interesting and eco-friendly uses for it.
Electric vehicles are eco-friendly because they don't produce tailpipe emissions, although the
generators producing the electricity used to charge EV batteries do emit pollutants. But
engineers are still working to make actually practical and economical in real world.
7) Nuclear power:
Nuclear power is any nuclear technology designed to extract usable energy from atomic
nuclei via controlled nuclear reactions. The only controlled method now practical uses
nuclear fission in a fissile fuel (with a small fraction of the power coming from subsequent
radioactive decay). Use of the nuclear reaction nuclear fusion for controlled power generation
is not yet practical, but is an active area of research.
And many kinds of fuel are under research and still not available in practical use, also to
brought this alternative fuel into the practice initial cost of research about in nature in
practical and installation of its pump and availability of its also the costly issue. Hence the
development automobile vehicle which can run on this new alternative fuel is also the major
issue to face before making practical use worldwide. Hence all these conditions make above
mention alternative fuel costly and time consuming.
Thus it is required to developed new technology which can works on fuel which is easily
available and can be brought into practice soon. It’s should have availability in future and can
be available worldwide easily, the new technology should also be convenient and economical
to use.
2.2 General Solution to the Problem.
Water hybrid engine is the first four stroke engine technology that works on using mixture of
petrol and water, hence it decreases the consumption of the petrol and equivalent work can be
obtain. This engine technology makes an appropriate mixture of water’s unsaturated steam
and petrol in carburettor.
Thus mixture is burn into the engine cylinder with spark plug and pressure is generated,
which pushes the piston and power stroke is obtain in engine. The use of this technology
reduces the consumption of petrol and the efficiency of the engine is increased.
Water Hybrid Engine 0.1 9
This technology is the ultimate solution the problem of scarcity of petrol and developing
solution to the alternate fuel problem. Water Hybrid Engine technology doesn’t require any
special change in engine technology, nor any special kind of fuel. For water hybrid engine
technology small modification is only required in four stroke engine, with a Water Preheater
kit.
Water hybrid engine technology is also economical in use, and it is economical in
construction, water hybrid engine is ECO FRIENDLY upto some extend. The reduction in
consumption of fuel decreases the amount of harmful gases in environment.

3.1 Working Principle.
Volumetric Expansion of Unsaturated Steam in Engine cylinder, at time of Combustion in
Cylinder produces Pressure, which is applied on Piston, and Power Stroke in obtain in Four
Stroke Engine.
In this engine, the unsaturated steam gets expanded, due to higher temperature generated at
the combustion of petrol in engine cylinder.
Temperature produced at the end of burning of fuel in engine range in 1200 to 2000 °C.

WORKING PRINCIPLE
Water Hybrid Engine 0.1 11
3.1.1 Otto Cycle.
The first person to build a working four-stroke engine, a stationary engine using a coal gas-air
mixture for fuel (a gas engine), was German engineer Nikolaus Otto. This is why the four-
stroke principle today is commonly known as the Otto cycle and four-stroke engines using
spark plugs often are called Otto engines.
The system is defined to be the mass of air that is drawn from the atmosphere into the
cylinder, compressed by the piston, heated by the spark ignition of the added fuel, allowed to
expand by pushing on the piston, and finally exhausted back into the atmosphere. The mass
of air is followed as its volume, pressure and temperature change during the various
thermodynamic steps. As the piston is capable of moving along the cylinder, the volume of
the air changes with the position of the cylinder. The compression and expansion processes
induced on the gas by the movement of the piston are idealized as reversible i.e. that no
useful work is lost through turbulence or friction and no heat is transferred to or from the gas.
Energy is added to the air by the combustion of fuel. Useful work is extracted by the
expansion of the gas in the cylinder. After the expansion is completed in the cylinder, the
remaining heat is extracted and finally the gas is exhausted to the environment. Useful
mechanical work is gained during the expansion process and some of that used to compress
the air mass of the next cycle. The useful mechanical work gained minus that need for the
next compression process is the net work out and can be used for propulsion or for driving
other machines. Alternatively the useful work gained is the difference between the heat added
and the heat removed.
An Otto cycle is an idealized thermodynamic cycle which describes the functioning of a
typical spark ignition reciprocating piston engine, the thermodynamic cycle most commonly
found in automobile engines.
The Otto cycle is constructed out of:
Top and bottom of the loop: a pair of quasi-parallel and isentropic processes
(frictionless, adiabatic reversible).
Left and right sides of the loop: a pair of parallel isochoric processes (constant
volume).
The isentropic processes of compression and expansion implies no loss of mechanical energy
due to friction and no transfer of heat into or out of the system during those processes, hence
the cylinder, and piston are assumed impermeable to heat during those processes. Heat flows
into the loop through the left pressurizing process and some of it flows back out through the
right depressurizing process, and the difference between the heat added and heat removed is
equal to the net mechanical work generated.
Water Hybrid Engine 0.1 12
Figure 3.2 P-V Diagram of Otto Cycle.
The processes are described as under,
Process 0-1 a mass of air is drawn into piston/cylinder arrangement at constant
pressure.
Process 1-2 is an isentropic and adiabatic compression of the air as the piston moves
from bottom dead centre (BDC) to top dead centre (TDC).
Process 2-3 is a constant-volume heat transfer to the working gas from an external
source while the piston is at top dead centre. This process is intended to represent the
ignition of the fuel-air mixture and the subsequent rapid burning.
Process 3-4 is an isentropic expansion (power stroke).
Process 4-1 completes the cycle by a constant-volume process in which heat is
rejected from the air while the piston is at bottom dead centre.
Process 1-0 the mass of air is released to the atmosphere in a constant pressure
process.
The Otto cycle consists of isentropic compression, heat addition at constant volume,
isentropic expansion, and rejection of heat at constant volume. In the case of a four-stroke
Otto cycle, technically there are two additional processes: one for the exhaust of waste heat
and combustion products at constant pressure (isobaric), and one for the intake of cool
oxygen-rich air also at constant pressure; however, these are often omitted in a simplified
Water Hybrid Engine 0.1 13
analysis. Even though those two processes are critical to the functioning of a real engine,
wherein the details of heat transfer and combustion chemistry are relevant, for the simplified
analysis of the thermodynamic cycle, it is more convenient to assume that all of the waste-
heat is removed during a single volume change.
3.2 Working of Water Hybrid Engine.
Figure 3.3 Water Hybrid Engine 0.1
Working mechanism of Water Hybrid Engine 0.1 is simple and unique. In this Four Stroke
Engine, water is preheated in copper pipe which is winded on exhaust outlet pipe (Silencer).
Water is stored in insulated copper cylindrical tank, outlet pipe of water tank is connected to
one end of copper winding and other end of copper winding pipe is again connected to the to
the water tank.
Copper pipe winding on exhaust pipe is filled with water from water tank, which is half filled
and other half tank is kept empty for accumulation of pressurised steam. When is engine is
running after some period ,water in copper pipe winding get heated due to high temperature
of exhaust gas flowing in exhaust pipe, There is a single pipe line inside the exhaust pipe
which has direct contact from exhaust gas at end of copper winding.
Water Hybrid Engine 0.1 14
Figure 3.4 Label Figure of Water Hybrid Engine 0.1
Water in the copper pipe winding gets converted into unsaturated steam, and again flown in
the water tank, to generate pressurised steam inside the water tank.
Pressure gauge meter is attached to the water tank in order to notify the steam pressure inside
the water tank. Appropriate pressure of steam is allowed to flow into the carburettor’s air
filter, the steam pressure can be regulated by steam outlet valve. These steam mixes with air
in air filter and enter into the carburettor, and in carburettor appropriate ratio of vaporised
petrol and steam mixture is flown into the engine cylinder at first stroke of piston and at
second stroke petrol and steam mixture is compressed, and with the combustion of petrol in
engine by spark through spark plug temperature of 1200° C to 2000° C is generated, which is
sufficient to have volumetric expansion of unsaturated steam inside the cylinder. Which
indeed induce pressure, due to which force is applied to the piston and power stroke is obtain.
Water Hybrid Engine 0.1 15
Figure 3.5 Label Figure of Water Preheater System in Water Hybrid Engine 0.1
And the remaining gases and steam in the cylinder is exhausted from the cylinder in the last
stroke of the engine.
The ideal Air/Petrol ratio for the combustion of fuel in the engine is 15:1, the ratio may vary
with acceleration, thus in this project, the intake of petrol is reduced to half and intake of air
is mixed with unsaturated steam partially at equal proportion, which maintain the ratio of
15:1 for the fuel combustion.

steam, with some pressure. For this purpose the pre heater kit is developed for this engine, for
the efficient working of this pre heater system, continuous flow of high temperature exhaust

EXPERIMENTAL ANALYSIS
Water Hybrid Engine 0.1 27
After the entry of steam and petrol inside the engine for combustion, engine continue to run
at the same RPM and torque at same acceleration, at satisfied condition.
Sometimes problem like leakage in copper tube and water tank can be detected, which lead to
pressure drop inside the system. As a result appropriate amount of required steam cannot be
generated or time consumption will increase for the process.
Proper insulation for copper pipe and water tank is required to attain optimum result and
efficiency cannot be obtained in the engine. Leakage in exhaust pipe will release the heat,
which is required for the heating of water in the copper pipe winding.
At high acceleration vibration is increased in the engine, so proper balancing of the wheel is
required.
5.3 Conclusion.
By above mention time analysis, it can be concluded that the time duration of working of
engine is increase with the intake of appropriate ratio of steam and petrol mixture, in
comparison with only petro intake at equal amount of fuel consumption, hence it increases
the efficiency of the engine.

ADVANTAGES & LIMITATIONS
Water Hybrid Engine 0.1 31
7.2 Limitation.
Water hybrid engine is working on water and petrol mixture, so the required torque
cannot be attain in some odd condition.
This technology is not much efficient in cold environment, as the formation of steam
process will become time consuming process.
There is formation of scale and slug in the copper pipe. Water used in this engine
should be pure water, distilled water, so that the formation of scale and slug in the
copper tube can be reduced.
Leakage in water preheater system can reduced the rate of generation of steam, and
required pressure of steam cannot be attain, heavy leakage can result in failure of
system.
Proper insulation is required in system to achieve maximum efficiency.
Water hybrid engine 0.1 needs few updates and modification, for more efficiency and
proper working.
It may require frequent Maintenance and cleaning due to insulation and leakage
problem of system.
Maintenance of the water preheater system is also required for effective functioning
of the system.
