How does radial engine work?

The radial engine came in use as the powerhouse for the early aviation. Due to high power output, it proves to be a quick replacement for the rotary engines, during the reign of World War 2nd. More efficiency and power were in the highest demand at that time. Now, jet engines work in place of radial engines.

The radial engines are the internal combustion engines and they have the same piston- cylinder arrangement. But the main point of difference is that the piston in the cylinder oscillates in the outward direction. These engines are also known as star engines. This is because they resemble the shape of the star when one views from the front. These engines are very powerful and generate enough power to help in an easy take-off of the aircraft.

Important parts of the Radial Engine

Piston- It transfers the force of expanding gases to the rotating crankshaft with the help of connecting rod. The piston has a tight movement in the cylinder and the piston rings ensure the minimum clearance in the piston and cylinder.

Crankshaft- this mechanical part helps in converting the reciprocating motion to the rotational motion.

Connecting rod– It works as an arm lever and transfers motion from piston to the crankshaft.

Inlet& outlet Valves– They allow the fresh air-fuel mixture and exits the present air-fuel mixture from the cylinder.

Articulating rod assembly– this assembly links all the connecting rods of the piston to the single part as a cylinder.

Spark plug– It delivers the electric current and ignites the air-fuel mixture in the combustion chamber.
