The main components of a two-wheeler engine include:
Cylinder: The cylinder is a cylindrical chamber in which the combustion process takes place. It houses the piston and allows the movement of the piston up and down.
Piston: The piston is a cylindrical component that moves up and down within the cylinder. It is connected to the crankshaft through a connecting rod and converts the pressure from combustion into reciprocating motion.
Crankshaft: The crankshaft is a shaft with several crank throws that convert the reciprocating motion of the piston into rotational motion. It transfers the power generated by the engine to the transmission system.
Valves: Most two-wheeler engines have two types of valves: intake valves and exhaust valves. These valves open and close to control the flow of air-fuel mixture into the cylinder and the exhaust gases out of the cylinder, respectively.
Camshaft: The camshaft is responsible for operating the valves. It has lobes or cams that push against the valve stems to open and close the valves at the appropriate times.
Spark Plug: The spark plug ignites the air-fuel mixture inside the combustion chamber, initiating the combustion process. It produces an electric spark that ignites the compressed mixture.
Fuel System: The fuel system includes components such as the carburetor or fuel injection system, fuel tank, fuel pump (if applicable), and fuel lines. It delivers the appropriate amount of fuel to the engine for combustion.
Cooling System: Some two-wheeler engines have a cooling system to maintain optimal operating temperature. It typically includes a radiator, coolant, water pump, and cooling fan.
Lubrication System: The lubrication system ensures that all moving parts of the engine are properly lubricated to reduce friction and wear. It includes an oil pump, oil filter, and various oil passages.
Electrical System: The electrical system provides power to components such as the ignition system, lighting system, and other electrical accessories.
These are the main components of a two-wheeler engine, though the specific design and configuration can vary depending on the manufacturer and engine type.
