📌📌Car Engine Parts Explained: Names, Functions & How They Work📌📌
1. Rocker Cover & Rocker Cover Gasket
The rocker cover is a protective lid on top of the cylinder head that seals and prevents oil from leaking. The rocker cover gasket ensures a tight seal between the rocker cover and cylinder head to prevent oil leaks.
2. Rocker Arm & Rocker Arm Axle
The rocker arm is a pivoting component that transfers motion from the camshaft to the valves, allowing them to open and close. The rocker arm axle supports and allows the rocker arms to pivot properly.
3. Valve Springs & Valves
Valve springs keep the valves closed when they’re not being acted upon by the rocker arm. Valves regulate airflow and fuel mixture entering the combustion chamber and allow exhaust gases to exit.
4. Cylinder Head & Head Gasket
The cylinder head sits on top of the engine block and contains passages for fuel-air mixture and coolant. The head gasket seals the gap between the cylinder head and engine block to prevent leakage of oil, coolant, and combustion gases.
5. Cylinder & Piston
The cylinder is the space where fuel combustion occurs. Inside the cylinder, the piston moves up and down, compressing fuel-air mixture and generating power.
6. Segments (Piston Rings)
Piston rings (or segments) ensure a tight seal between the piston and cylinder wall, preventing oil from entering the combustion chamber while maintaining proper compression.
7. Spark Plugs
Spark plugs ignite the air-fuel mixture in petrol engines, initiating combustion.
8. Engine Block
The engine block is the foundation of the engine, housing the cylinders, crankshaft, and other key components.
9. Connecting Rod & Rods
The connecting rod links the piston to the crankshaft, converting the piston's linear motion into rotational motion. Rods refer to multiple connecting rods in the engine.
10. Crankshaft & Flywheel
The crankshaft converts the up-and-down motion of the pistons into rotational motion, driving the wheels. The flywheel
