What is piston?

                              Piston 

1)How A Piston Works

Inside every engine you find a cylinder. Within that cylinder are your pistons. The number of pistons you have, as well as their arrangement, is determined by the type of engine you have. The piston’s job in all of this is to transfer force from the exploding gas up to the crankshaft. Each piston inside the cylinder is connected by a rod which allows it to move up and down. Air and fuel are mixed together and pulled into the cylinder. The cylinder compresses the mixture, the spark ignites it, and you have power. The resulting expanding gases from this combustion drive the engine piston forward to move the same way that pushing down on the pedal of a bike causes the wheel to move.

* Basic Types of Piston *

1)Flat top  piston 

2)Dish piston 

3)Dome piston

1)Falt top Piston 

a flat-top piston has a flat top. Flat-top pistons have the smallest amount of surface space; this enables them to create the most force. This type of piston is ideal for creating efficient combustion. Flat-top pistons create the most even flame distribution.

*Use*

Flat Top Piston

These pistons are typically used in mass produced engines. They are easy to manufacture and this keeps the cost of the engines low.

2]Dish Piston 

Dish pistons present the least problems for engineers. That is more because of where they are used than any property they themselves hold. They are shaped just like a plate with the outer edges slightly curling up. Typically, dish pistons are used in boosted applications which do not require a high-lift camshaft or high compression ratio.

*Use*

This piston has a bowl- or dish-shaped top. It is used to reduce Compression Ratio because it adds volume to the chamber. It can be used in turbocharged or supercharged engines to help avoid Detonation. It makes for a fast-burning, compact combustion chamber.

3]Dome piston

Piston Dome refers to the amount of added volume on top of the piston compared to a flat top piston. This added volume increases the Compression Ratio and therefore should increase performance.

*Use*

Dome Pistons are also used in 2 stroke engines, mostly to deflect the inlet charge up toward the spark plug, and not let it flow directly to the exhaust ports.
