Automobile engines are complicated mechanisms that are made up of several internal parts that work like clockwork to produce that power that moves your vehicle. In order for the engine to operate properly it needs all of its parts to be in good condition. One fault can be disastrous! Let’s take a look at the main parts of the engine.
The block is the main part of the engine. All other parts of the motor are essentially bolted to it. Inside the block is where the magic happens, such as combustion.
Pistons pump up and down as the spark plugs fire and the pistons compress the air/fuel mix. This reciprocating energy is converted to rotary motion and transferred to the tires by the transmission, via the driveshaft, to make them spin.
The cylinder head is attached to the top of the block in order to seal the area to prevent the loss of gases. The spark plugs, valves and other parts are fitted to it.
Crankshaft Located near the bottom of the engine block, this is the part that converts energy from reciprocating to rotary.
The camshaft opens and closes the valves in perfect timing with the rest of the parts.
The valves regulate the flow of air, fuel and exhaust fumes inside the cylinder head. There are both intake valves and exhaust valves.
The oil pan, also known as the oil sump, is attached to the bottom of the engine and stores all the oil used in the lubrication of the engine.
When an engine is rebuilt all of these parts will be cleaned and machined as needed to return them to a like new condition.
