Parts Of An Engine

Car engines are designed around sealed, resilient metal cylinders. Most modern vehicles have between four and eight cylinders, though some vehicles can have as many as sixteen!

The cylinders are made to open and close at precisely the correct time to bring in fuel to combine with the spark for burning internally, and to release the exhaust gases produced.

While many of us think of the engine as one major component, it’s actually made up of several individual components working simultaneously.

You may have heard of some of these car engine parts names but it’s important to know what their role is and how they relate to other components within the engine.

1. Engine Block
The engine block is the main part of an engine. Often made of aluminum or iron, it has several holes to contain the cylinders as well as provide water and oil flow paths to cool and lubricate the engine. Oil paths are narrower than water flow paths.

The engine block also houses the pistons, crankshaft, camshaft, and between four and twelve cylinders depending on the vehicle, in a line, also known as inline, flat, or in the shape of a V.

All other parts of the motor are essentially bolted to it. Inside the block is where the magic happens, such as combustion. For more information read The basics of the Engine block.

2. Piston

Are a cylindrical apparatus with a flat surface on top. The role of the piston is to transfer energy created from combustion to the crankshaft to propel the vehicle. Pistons travel up and down within the cylinder twice during each rotation of the crankshaft.

Pistons on engines that rotate at 1250 RPM, will travel up and down 2500 times per minute. Inside the piston, lie piston rings that are made to help create compression and reduce the friction from the constant rubbing of the cylinder.
