Green Engine
- 2. INTRODUCTION The greenengine is one of the most interesting discoveries of the millennium. This engine is a piston less one. Variable compression ratio, direct air intake, direct fuel injection, multi-fuel usage etc. It is comparatively high efficiency and exhaust emissions are nearly zero. Prototypes of the engine have been developed. Generators have been produced with the green engine.
- 3. WHAT IS AGREEN ENGINE Green engine is an internal combustion engine with some or major modifications in its parts and design. The green engine is one of the most interesting discoveries of the new millennium. The efficiency of the engine is high when compared to the contemporary engines and also the exhaust emissions are near zero The significance of the engine lies in the efficiency when the present world conditions of limited resources of energy are considered.
- 4. NEED OF AGREEN ENGINE Today the world is facing the major problems regarding energy crisis. Along with this we are facing major environmental trouble due to increase in harmful gasses which are evolved from nowhere else but the combustion of these conventional energy sources. Major portion of fuel is burnt in the engine used for various purposes like main automobiles, generators, power plants etc. Statistics shows that the daily consumption of petroleum all over the world today is 40 million barrels, of which about 50 percent is for automobile use.

- 8. CONSTRUCTION AND WORKING Theterm phase is used instead of stroke is actually associated to the movement of piston. But this engine has no piston. The six phases are : Intake, Compression, Mixing, Combustion, Power and exhaust. The engine has a set of vanes, a pair of rotors having a no of small pot like containers. The engine also contains two air intake ports, and a pair of fuel injectors and spark plug.
- 9. SIX PHASES OFGREEN ENGINE ARE : 1. INTAKE The air arrives to the engine through the direct air intake port in the absence of an air inlet pipe, throttle and inlet vales 2. COMPRESSION The rushing air from the duct is pushed by the blades into the small chambers in the rotor. 3. MIXING In this phase the fuel mixes well with the compressed air. This is for the deletion of CO emission.
- 10. 4. COMBUSTION Inthis phase chamber rotates towards the end of its path. A spark files from plug into the air fuel mixture. 5. POWER The expanded gas rushes out of the chamber through narrow opening. 6.EXHUST As thermal energy is fully utilized, the exhaust gases bring less het energy.
