GREEN ENGINE
This engine is constructed in such a way that it can
produce higher efficiency by emitting zero emission of
harmful gases,because of complete burning of fuel.It is
light,small and of low cost.It is benificial for the
environment.It can solve the problems of over
consumption of fuel.It creates a revolution in the field
of engine mechanism.It has two strokes more than the
four stroke engine.In future it may be used in every
technical field due to higher output and low pollution
factor.

5. Engine revolution…

6. Global Grim……….
• energy exhaustion,
atmospheric pollution and
climate warming
• five main energy resources
petroleum, natural gas, water
coal and nuclear energy.
• consumption of petroleum
constitutes approximately
60% of energy used from all.

7. The “Burning” problem…
• daily consumption of petroleum by automobiles all over the
world is over two million tonnes.
• 500 million tonnes of carbon monoxides(CO), 100 million
tonnes of hydro carbons(HC), of carbon, 50 million tonnes
of nitrogen oxides(NOx)are emitted into the atmosphere
every year.
• However, it is estimated that petroleum reserve in the
globe will last for only 38 years .

8. Ambidexterous Engine……
• After 25 years'
explorations, a new
type of engine with a
totally new concept,
Green Engine, which
can satisfy the
requirement of our
era, has been
invented.

9. Innovations ………
• Sequential Variable Compression Ratio
• Constant Volume Combustion and Self-
adapting Sealing System.
Therefore an engine having extremely high
thermal efficiency, near-zero emissions, quietness
light and small, lower cost with capability of
burning of various fuels, has come into being.

10. Technical Features ……….
• Compared to conventional piston engine operated on
four phases, the Green Engine is an actual six-phases
internal combustion engine with much higher expansion
ratio.
intake, compression, mixing, combustion,
power and exhaustion
resulting in the high air
charge rate ,satisfactory air-fuel mixing, complete burning
high combustion efficiency and full expansion.

12. Air Intake….
• Direct Air Intake ->no air-inlet pipe, throttle and
inlet valves
Highest volumetric efficiency which makes
engine produce a high torque of output on all
speed ranges is achieved, and the pump loss which
consumes the part of engine power is eliminated.
Air filter is directly connected to the intake port of
the engine, together with the less heating effect of
air intake process

13. Strong Swirling
• tangential air duck is between combustion chamber and
compression chamber, a very strong swirling which
could last until gas port opened can be formed while air
are pumped into the combustion chamber.
Consequently, the air-fuel mixing and the combustion
process can have a satisfying working condition.

14. Sequential Variable Compression Ratio
• It can provide the most suitable compression ratio for
the engine whatever operation mode it works on with
burning variety of fuels. Therefore, an excellent
combustion performance is attained.
Direct Fuel Injection
•Direct fuel injection can provide higher
out put and torque, while at the same
time it also enhances the response for acceleration.

15. • Super Air-fuel Mixing …
the independent air-fuel mixing phase is having
enough time for mixing air and fuel under strong
swirling and hot situation, the engine is capable to
burn any liquid or gas fuels without modifications.
ideal air-fuel mixture could delete CO emission
swirling and rotation of the burner makes the air-fuel
mixture more dense near the spark plug ,it benefits to cold
engine starting and managing lean-burning, and allowing
the engine use of mass control for output.

16. Lowest Surface to Volume Ratio..
a lowest surface-to-volume ratio and the engine is
having less heat losses and high combustion efficiency.
Constant Volume Combustion
fuels can generate more energy while the
combustion is occurred on the constant volume

18. Advantages
• High Efficiency
As Green Engine is very compact with multi-power pulses,
the size and weight could be only 1/5 to 1/10 of the
conventional piston engines on same output
the thermal efficiency of the Green Engine could be
potentially as high as 65%
Limited Parts…
There are only some dozens of parts easily to
be
manufactured in the engine structure.

19. • Multi-fuels …
Due to Six Phases of Working Principle, Super Air-fuel
Mixing Process and Constant Volume Combustion with
Controllable Time the Green Engine becomes the only
real multi-fuels engine on our planet; any liquid or gas
fuels can be burned well
Near-zero Emissions…
With perfectly air-fuel mixture, complete combustion under
lower peak temperature and free of quenching effect,
the emissions of CO, HC and NOx could be near zero

20. • Low Cost
Limited parts, small in size, light in weight and
depended upon current mature materials and manufacture
technologies, it means that it would be to being done on the
much lower cost on manufacture, transportation, installing
to other devices, and maintenance.

21. Applications
• The Green Engines could be used as the ideal powerplants on a
very wide range of applications in transportation, communication,
farm, mine, engineering, entertainment, sports and military uses,
such as automobiles, aircrafts, boats, ships, hovers, tractors,
locomotives, generators, motorcycles, snowmobiles, chainsaws,
helicopters, UAVs, tanks, torpedoes, submarines etc.

22. CONCLUSION
• Emerging vehicle systems demand new solutions: -
Integrated vehicle / propulsion design - Intelligent /
adaptive systems - Sustained High Speed Flight
• This process is aggressively pursuing advanced projects
• that will meet or exceed projected future propulsion
• requirements
• Integrated Systems Level Demonstrator Vehicles are key
to
• technology transition
• Partnership approach increases advocacy and supports
• transition
