Six Stroke Engine Animation.

An Indian from Kerala "Gods own country" has developed and patented the six stroke petrol engine. Mr. Chanayil Cleetus Anil a mechanic from Mamangalam, Ernakulam district. His hard work of ten years resulted in this creation. He claims that with this engine more mileage can be developed.
This invention can create a revolution in the automotive industry in the scenario of the fuel prices going up.Automobile Engineering tutorials
Working of this engine is explained below:
The different strokes are:
1. Suction stroke
2. Compression stroke
3. Power stroke
4. Exhaust stroke
5. Air intake (scavenging)
6. Air Exhaust (scavenging)

The engine has four valves: suction valve (air fuel mixture suction), suction valve (air suction), exhaust valve (smoke exhaust), and exhaust valve (air exhaust)
Suction stroke: In this stroke the piston moves from TDC to BDC. The suction valve opens and air fuel mixture enters the cylinder.
Compression stroke: piston moves from BDC to TDC, all the valves are in closed condition.
Power stroke: piston moves from TDC to BDC, all the valves in closed condition. Spark happens and combustion occurred, due to the pressure produced in the combustion piston comes down to BDC.
Exhaust stroke: piston moves from BDC to TDC and exhaust valve opens and pushes out the exhaust gas.
Air intake stroke (scavenging stroke): piston moves from BDC to TDC and the air inlet valve opens resulting in the air from the atmosphere to be sucked in.
Air exhaust stroke (scavenging stroke): piston moves from BDC to TDC resulting in pushing the air out.
The scavenging stroke flushes the system and make it clean.
