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 there are several components on an engine, we`ve compiled a list of the most essential car engine parts and their functions, that power your vehicle. Refer to the diagram to locate where they reside on your engine.
Engine valve – This is the very core of the 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 the 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.
Pistons – 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.
Timing Belt/Chain – The camshaft and crankshafts are synchronized to ensure the precise timing in order for the engine to run properly. The belt is made of a heavy-duty rubber with cogs to grasp the pulleys from the camshaft and crankshaft. The chain, similar to your bicycle chain wraps around pulleys with teeth.
