  • AUDI 4.0 TFSI engine with cylinder on

    demand(COD)

    The new 4.0 TFSI engine has a powerful V8 with twin turbochargers, is

    equipped with cylinder on demand technology. When operating at part

    load, four of its cylinders are deactivated. This reduces fuel consumption

    by an average of 5%. Active noise control system reduces the noise and

    vibration created by the engine when it is switched on to 4 cylinder

    mode. On the new 4.0 TFSI, cylinders are deactivated if the load on the

    engine is low. It take effects depending on engine speed, is between

    about 25 and 40 percent of maximum torque, in other words about 120

    and 250 Nm. In this operating range the mean effective pressure rises to

    eight bar. Coolant temperature must be at least 30C and third gear or

    higher must have been selected. The engine must be running at more

    than idle speed, namely between 960 and 3,500 rpm. If these

    preconditions are satisfied, the system closes the inlet and exhaust

    valves of two cylinders on each bank. The V8 continues to run as a V4

    with a regular firing order, but with the mixture in only two cylinders

    instead of four being ignited on each revolution of the crankshaft.

    Instead of 1 5 4 8 6 3 7 2, the firing order is then 1 4 6

    7.

    1. LATEST TRENDS IN AUTOMOBILES

  • The valves are closed by the Audi valvelift system (AVS). These system slides by electromagnetically. When the driver accelerates the pedal rapidly the deactivated cylinders come into motion. The process takes place smoothly & quickly in just 300milliseconds.

  • AUDI e-diesel and e-ethanol

    Audi has developed new CO-neutral fuels. The new technology

    involves that the Microorganisms utilize solar energy to produce

    synthetic ethanol and synthetic diesel from carbon dioxide and water.

    The process is relatively simple; fuels are produced from CO and salt

    water with the help of solar energy. The fuel is produced in a specially

    developed solar converter system.

    The fuel is generated when it utilises the co2 from the industries and the

    salt water or brackish water. The sun provides the energy to process

    that the organisms need to produce the fuel. co2, water & solar energy

    set the circulating production process in the motion in which billions of

    microorganisms produce fuel. By the separation of water from the fuel

    produced the Audi e-diesel or e-ethanol are filled in filling stations and is

  • used in Audi cars. These fuels does not cause any harm to the

    environment.

  • 2015 BMW i8

    BMW has designed a plug-in hybrid sports car offering the nimble

    performance and outstanding efficiency. The passenger chamber has

    made with carbon fibre reinforced plastic (CFRP). The engine is built

    with 1.5L petrol engine with twin power turbo technology. The three-

    cylinder combustion engine in the BMW i8 develops 170 kW & 231 hp

    which drives the rear wheels, while the 96 kW & 131 hp electric motor

    draws its energy from a lithium-ion battery, which can be charged from a

    conventional domestic power socket, and sends its power to the front

    axle. The i8 enables a range of up to 37 kilometres in the EU test cycle

    and a top speed of 250 km/h on electric power alone. While using the

    both electrical energy and engine energy it boost ups 0-100kmph in just

    4.4sec. The BMW i8 is the first BMW production model to be powered by

    a three-cylinder petrol engine. The three-cylinder's BMW Twin Power

    Turbo technology comprises a high-performance turbocharging system

    and direct petrol injection with high-precision injectors positioned

  • between the valves. BMW Twin Power Turbo technology and low

    internal friction improve both fuel efficiency and torque characteristics.

    The electric motor develops maximum power of 96 kW/131 hp and instantly produces its maximum torque of 250Nm. The electric motor drives the car to a top speed of 120kmph. The motor derives its energy from the lithium-ion battery which is centrally mounted underneath the floor of the vehicle. The rear wheels of the BMW i8 are driven by the petrol engine via a six-speed automatic transmission, while the front wheels receive their power from the electric motor. The high-end chassis and suspension technology of the BMW i8 is based on a double-wishbone front axle and a five-link rear axle, whose aluminium components have been specially designed and manufactured in order to optimise both their weight and strength & the Electric Power Steering offers easy handling. The BMW i8 is equipped with the following technologies like:-

  • Dynamic Damper Control:- The electronically controlled dampers endow the vehicle with sharper agility without any loss of ride comfort. The dampers' characteristics change according to the selected driving mode to deliver the desired vehicle dynamics. The DSC (Dynamic Stability Control) system includes the Anti-lock Braking System (ABS), Cornering Brake Control (CBC), Dynamic Brake Control (DBC), Brake Assist, Brake Standby, Brake Drying function, Start-Off Assistant, Fading Compensation, Active Differential Brake (ADB-x), Driving dynamic impellent torque pre-control, E-Traction, as well as the push button-activated Dynamic Traction Control (DTC) mode.

  • 2. DEVELOPMENTS IN

    MECHANICAL FIELD

    Non-destructive testing

    -Non-destructive testing (NDT) is a wide group of analysis techniques

    used in science and industry to evaluate the properties of a material

    without causing damage.

    Types of NDT:-

    Visual Ultrasonic Dye penetrant inspection (DPI) Shearography and many more techniques.

    1. VISUAL INSPECTION:- Basic principle: illuminate the test specimen with light and examine the specimen with the eye by using Magnifying Glass, Magnifying Mirror, and Microscope. 2. ULTRA SONIC TESTING:- Based in the propagation of ultrasonic waves in the object or material tested. It absorbs or deflects the sound Waves, which are then detected as changes in the waves. 3. DYE PENETRANT INSPECTION:- It is also called as also called liquid penetrant inspection (LPI). It is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). The penetrant may be applied to all non-ferrous materials and ferrous materials. Inspection steps for LPI:- 1. Pre-cleaning 2. Application of penetrant 3. Excess Penetrant Removal 4. Application of Developer 5. Inspection 6. Post Cleaning

  • 1. Section of material with a surface-breaking crack that is not visible to

    the naked eye.

    2. Penetrant is applied to the surface.

    3. Excess penetrant is removed.

    4. Developer is applied, rendering the crack visible.

    4. SHEAROGRAPHY:- Shearography or speckle pattern shearing

    interferometry is a measuring and testing method. It uses coherent

    light or coherent sound waves to provide information about the quality of

    different materials in non-destructive testing. It is widely used in

    aerospace and automotive works. When a surface area is illuminated

    with a highly coherent laser light, a stochastical interference pattern is

    created. This interference pattern is called a spe
