Electric Vehicle Engine Components, a car engine is more than an engine designed as an integrated unit and a single part. The components of a car engine are divided into two main parts: a mechanical section and an electrical section. We will learn about the components of both together.
Electric Vehicle Engine Components
Cylinder
- The cylinder is one of the basic mechanical parts of a car engine.
- where the processes of fuel combustion occur and the piston moves up and down generating the required movement.
- The cylinders are lined up next to each other as an integrated block called a cylinder block.
- and engines are classified according to the dimensions and orientation of the cylinders.
- A cylinder is usually made of iron or aluminum, and the reason for favoring aluminum is its lightness and good heat dissipation.
Piston
- It is the cylindrical part that moves up and down the cylinder.
- and it usually has a diameter slightly less than that of the cylinder to ease the direct wear of its surface.
- It is surrounded by three circular rings known as piston rings.
- which are concerned with preventing the leakage of oil and various gases to and from the combustion chamber.
- Two of its rings are usually made of iron or aluminum alloy, while the third is made of aluminum.
Crankshaft
- One of the most important components of a mechanical car engine.
- it converts the reciprocating movement of the piston into rotational motion, and it is usually made of steel.
Connecting Rod
- It is the part responsible for transmitting the movement between the piston and the crankshaft.
- where it is converted into rotational movement, as we mentioned.
- The connecting rod has two ends, one of which is small.
- which is attached to the piston part with the help of the so-called gudgeon pin, and the other is large.
- which is attached to the crankshaft with the help of the crank pin.
- The connecting rod is usually made of forged steel or lightweight aluminum alloy.
- which contributes to heat absorption.
Cylinder Head
- It is the part fixed to the head of the cylinder block, and it includes the valves and ignition elements.
- The inlet and exhaust port are also installed inside it.
- The cylinder heads are part of the combustion chamber.
- Number of these heads varies according to the type of engine.
- some have a common head for all cylinders, while some feature a separate head for each cylinder.
- These heads are usually made of iron or aluminum alloy.
Valves
- There are two types of valves within a car’s engine components.
- one responsible for introducing the air-fuel mixture (or only air in diesel engines) into the combustion chamber.
- It is called the inlet valve, while the exhaust valve works to take the exhaust gases out of the cylinder.
- Valves are usually made of alloy steel and are usually filled with sodium in order to increase their ability to transfer heat.
