Journal of Engineering Research and Applications www. One with an existing condition Flat headed pistons and another with a new design Dome headed piston. Here, the modeling of engine piston with flat headed type and with dome headed types was done in workbench. At first the scavenging effect of flat headed piston is analyzed. Later the simulation of piston with dome headed type was also checked. Analyzing the variations from each and selected the best method for scavenging. Finally the scavenging efficiency is calculated for both type arrangements.

The inlet valve is opened and the exhaust valve is closed.

The partial vacuum created by the downward movement of the piston sucks in the fresh charge mixture of air and petrol from the carburetor through the inlet value. The stroke is completed during the half revolution O of the crank shaft, which means at the end of the suction stroke, piston reaches the bottom head centre position. As the piston moves up, the charge is compressed.

During compression the pressure and temperature rises. This rise in temperature and pressure depends upon the compression ratio in petrol engines the compression ratio generally varies between and Just before the completion of the compression stroke, the charge is ignited by means of an electric spark, produced at the spark plug. Just before the completion of compression stroke, causes a rapid rise of temperature and pressure in the cylinder.

Theory: in this engine the cycle is completed in 2- strokes of the piston or in one revolution of crankshaft.

The preparatory strokes suction and exhaust are combined with the working strokes compression and expansion. In 2- stroke engines, instead of valves ports are used for suction and exhaust purposes.

As the moving parts are less; mechanical efficiency is high. But thermal efficiency of the engine is lower due to some charge escaping without burning, through the exhaust port. Also, in 2 stroke engines, as the power is available once in every revolution of the crankshaft, flywheel required is less in weight and small in size. Two Stroke Petrol Engine: Fig.
