SINGLE CYLINDER FOUR STROKE DIESEL ENGINE TEST R IG (WITH ROPE BRAKE DYNAMOMETER )

AIM:

To determine

Brake horsepower

Fuel consumption

Specific fuel consumption

Brake thermal efficiency

Heat equivalent to BHP

Heat carried awy by engine jacket Air consumption

Swept volume

Volumetric efficiency

DESCRIPTION:

The diesel engine test rig consists of following arrangements to conduct the experiment:-

FUEL INPUT MEASURING ARRANGEMENT This arrangement consists of a fuel tank of suitable capacity mounted on a stand. The fuel goes to the

engine through a 50 ml burette. The burette facilitates the measurement of fuel consumption for a

definite period of time with the help of stopwatch.

ARRANGEMENTFOR MEASURING THE HEAT CARRIED BY COOLING WATER .

Suitable pipefitting is provided for circulating the cooling water into the engine. For measuring therate of flow of cooling water, a water meter is provided. With all these arrangement one can find the

heat carried away by cooling water. The temperature of inlet and outlet water can be directly read

from the digital temperature indicator.

AIR INTAKE MEASURING ARRANGEMENT.It consists of an orifice, a diaphragm base manifold and U-tube manometer. With the help of orifice

and manometer the volume of the air sucked can be calculated.

LOADING ARRANGEMENT:A rope brake dynamometer arrangement with a brake drum coupled to the engine shaft and provided

with a cooling water arrangement and spring balances. The load can be varied by increasing the rope

tension on the brake drum with moving the hand wheel provided on the frame.

ENGINE SPECIFICATIONS:Engine : Single cylinder, 4 stroke, vertical, water cooled

H.P : 5 H.P @ 1500 RPMBore diameter : 80 mm

Stroke length : 110 mm

Brand : Kirloskar

UTILITIES R EQUIRED:

Diesel: 5 liters

Continuously water supply for engine cooling.

Space required: 1.7m × 0.7m

EXPERIMENTALPROCEDURE:

Fill oil in the oil sump of engine. It should be in between the marks provided on the oil dipstick

if oil level is reduced, add clean oil (SAE – 40) to the crankcase by opening the cover of valve

provided, at the top of the engine.

Fill the diesel in diesel tank.

Fill the manometer up to half of the height of manometer with water.

Fill the burette with diesel by opening the valve provided at the lower side of burette. Close the

valve after filling the burette.

Supply the diesel to the engine by opening the valves provided in the fuel supply line.

Open continuous cold water supply to the engine jacket.

Start the engine with starting handle and let it run for 5 minutes under no lead condition.

When engine start running smoothly, firstly load the engine slightly with the help of rope brakedynamometer and then gradually increase the load. Then immediately open the cooling water

to break drum of the dynamometer.

Run the engine for 2 minutes so that it can stabilize.

Note the reading of both spring balance and note the RPM of pulley with tachometer.
