INTRODUCTION
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 Types of six stoke
engine
According to first approach
crower six stoke engine bajulaj six stoke engine
According to second approach

according to 1st approach
1st - Stroke, Suction Stroke The intake valve is open.
Intake of pure air in the cylinder.
The heating chamber valve is open.
Compression of pure air in the heating chamber.2nd Stroke,
Compression Stroke
The Combustion chamber valve is open.
Release of combustion gases in the cylinder.3rd - Stroke,
power(work) Stroke
The exhaust valve is open.Exhaust of the combustion gases.4th
Stroke, Exhaust Stroke
5th - Stroke, power(work) Stroke The heating chamber valve is
open.
Release of hot pure air into the cylinder.
6th Stroke, Recompression StrokeThe Combustion chamber valve is
open.Recompression of the pure air in the combustion
chamberAdvantages
Gas flow intake increases of 20%.
Increased power and torque output.
Better fuel economy.
Higher compression ration.
Clear burning and reduced emission15DisadvantagesComplex in head
design.
Complex in cam design due two power stokes.
Thermodynamically engine is stable, yet design of parts becomes
more complex due to increase in torque.conclusion More workdone for
same fuel supply, high volumetric efficiency, reduce the emissions
so that we have a bright future in six stoke engineAny
questions????
