Six Stroke engine

Six-stroke engine :

In the six-stroke engine developed by the students of College of Engineering, Trivandrum, India, the first four strokes are the same as a four stroke internal combustion engine. 

After the exhaust stroke, instead of air/fuel mixture (as in case of petrol engines), fresh air is sucked into the cylinder from the air filter, and is removed during the sixth stroke. The valve overlaps have been removed and the additional two strokes have been provided for better scavenging, using air injection.

The engine shows 40% reduction in fuel consumption and dramatic reduction in pollution. Its specific power is not less than that of a four-stroke petrol engine. The engine can run on a variety of fuels, ranging from petrol and diesel to LPG. An altered engine shows a 65% reduction in CO pollution when compared with the four stroke engine from which it was developed.

The TrivandrumTeam : Aaron Joseph George, Arun K Nair, Boby Sebastian, and Krishnaraj U. It took them almost two years to develop the engine. 

Its features are:

1. Reduction in fuel consumption 
2. Dramatic reduction in pollution 
3. Better scavenging and more extraction of work per cycle 
4. Lower working temperature makes it easy to maintain optimum engine temperature level for better performance 
5. Less friction, so less wear and tear 
The six-stroke engine does not require any basic modification to the existing engines. All technological experience and production methods remain unaltered. 

This Engineering students have been awarded the 'Indian Society for Technical Education - National awarded' for Best B. Tech project of 2006. (ISTE/BBSBEC-B.Tech./Award/2006)
