What is six stroke engine:- An engine in which piston reciprocates 6 times in one cycle giving two power strokes with same fuel supply.

It works based on four stroke engine.

IntroductionMalcolm beare built an innovative hybrid design

of the I.C engine , by combining a two stroke with a four stroke engine.

The Beare Head uses a piston and ports very much like a two stroke engine to replace the over head valve system that is found in four stroke engines today. The four stroke block, pistons and crankshaft remain unaltered. This combination of two stroke and four stroke technology has given the engine its name the “six stroke engine” (2 + 4 = 6)

Key attributes of the Beare Head are:

Increased power, Increased torque, Fewer, lighter reciprocating parts, Simpler manufacture.

Working principal of Six stroke Engine:-

1st - Stroke, Suction Stroke

The intake valve is open. Intake of pure air in the cylinder.

2nd –Stroke, Compression Stroke

The heating chamber valve is open. Compression of pure air in the heating chamber.

Combustion chamber completely sealed and ready for the combustion.

3rd - Stroke, power(work) Stroke

The Combustion chamber valve is open. Release of combustion gases in the cylinder.

4th – Stroke, Exhaust Stroke

The exhaust valve is open. Exhaust of the combustion gases.

5th - Stroke, power(work) Stroke

The heating chamber valve is open. Release of hot pure air into the cylinder.

6th – Stroke, Recompression Stroke

The Combustion chamber valve is open. Recompression of the pure air in the combustion chamber

Polusion Test Results:-

In a six stroke engine the energy absorption is less because of slower acceleration of reciprocating parts.

It reduces the weight and complexity of the engines head by as much as 50%. Instead of using energy to drive the head.

Torque is increased by 35% and efficiency increased by the same.

Reduction in Fuel at least 40%.

Reduction in pollution up to 65%.

Higher overall efficiency.

Lower Engine Temperature.
