COMPARISON OF 4-STROKE AND 6-STROKE ENGINE

4-STROKE• One Power Stroke• Up to 35% Efficiency• More Emissions• Minimal Power• One Working Fluid

6-STROKE• Two Power Stroke• Up to 45% Efficiency• Comparatively Less Emission• More Power• Two Working Fluid

ENGINE MODIFICATIONS REQUIRED TO CONVERT 4 STROKE TO 6 STROKE

1.Crankshaft to Camshaft ratio modification2.Crank has 1080 degree of rotation for 360 degree rotation of

camshaft3.Sprocket have teeth ratio 3:14.34 teeth sprocket is replaced with 42 teeth of camshaft5.17 teeth sprocket is replaced with 14 teeth of crankshaft6.Changes in cam lobes7.360 degree of cam is divided into 60 degree among 6 strokes

ADVANTAGES

• Reduction in fuel consumption.• Dramatic reduction in pollution normally upto 65%.• Less friction-so less wear and tear.• The six stroke engine does not require any major modifications .• Engine cooling system is not required…so the overall weight of engine is

reduced.• Higher overall efficiency .• Second working fluid I.e. Water is found in abundance compared to fossil fuels.• More power obtained…due to two power strokes
