Piston engines are a type of internal combustion engine that are widely used in various applications, from automobiles to airplanes. Understanding how they work requires a look into the basic components and the mechanics of the combustion process.

At the core of a piston engine are its two primary components: the cylinders and the pistons. The engine consists of multiple cylinders, each containing a piston that moves up and down within it. The movement of the pistons is the result of the combustion of fuel and air mixture, ignited in the cylinder.

The process begins with the intake stroke, where the piston moves down the cylinder, creating a vacuum that draws in a mixture of air and fuel. When the piston reaches the bottom of the cylinder, the intake valve closes, and the piston moves back up, compressing the air-fuel mixture. This high pressure and temperature prepare the mixture for combustion.
Once the piston reaches the top of its stroke, a spark plug ignites the compressed air-fuel mixture. This explosion forces the piston back down the cylinder during the power stroke. The energy generated during this stroke turns the crankshaft, which ultimately powers the vehicle or machinery.
After the power stroke, the piston moves back up the cylinder again during the exhaust stroke. This motion expels the burnt gases from the combustion process through the open exhaust valve. Once this cycle is complete, the piston is ready to begin the process again.
Piston engines can be classified into two main types: two-stroke and four-stroke engines. Two-stroke engines complete a power cycle in two strokes of the piston, making them simpler and lighter but often less efficient and more polluting. In contrast, four-stroke engines, which we have discussed, take four strokes to complete a power cycle, allowing for a more efficient and cleaner combustion process.
