Auto Engine Piston For Korean Car Hyundai Kia

The aviation piston engine is a machine that uses gasoline and air to mix and burn in a closed container (cylinder) to expand work. Piston engines must drive the propeller to generate a push (pull) force from the propeller. Therefore, as the power unit of the aircraft, the engine and the propeller are inseparable.

(1) The main components of the engine piston 

Mainly composed of cylinder, piston, connecting rod, crankshaft, valve mechanism, propeller reducer, casing and so on.

The cylinder is where the mixture (gasoline and air) burns. The cylinder contains the piston for reciprocating motion. The cylinder head is equipped with an electric spark plug (commonly known as a nozzle) for igniting the mixture, as well as inlet and exhaust valves. The cylinder temperature is high when the engine is working, so there are many fins on the outer wall of the cylinder to expand the heat dissipation area. The arrangement of the cylinders on the engine casing (the casing) is mostly star-shaped or V-shaped. Common star engines range from 5, 7, 9, 14, 18 or 24 cylinders. In the case where the single cylinder volume is the same, the more the number of cylinders, the greater the engine power. The piston withstands the gas pressure to reciprocate within the cylinder and converts this motion into a rotational motion of the crankshaft through the connecting rod. A connecting rod is used to connect the piston to the crankshaft. The crankshaft is the component of the engine's output power. When the crankshaft rotates, the propeller rotates by the reducer to generate a pulling force. In addition, the crankshaft also drives some accessories (such as various oil pumps, generators, etc.). The valve mechanism is used to control the intake and exhaust valves to open and close at regular intervals.
