The structural composition of a single cylinder engine
Cylinder block: The cylinder block is the main part of the engine, which forms the combustion chamber inside and provides space for the piston to move.
Piston: The piston performs reciprocating motion inside the cylinder and is connected to the crankshaft through a connecting rod, converting the pressure of the gas into the rotational torque of the crankshaft.
Crankshaft: The crankshaft converts the reciprocating motion of the piston into rotational motion and is a key component for the engine to output power.
Cylinder head: The cylinder head is installed on the cylinder block, forming a combustion chamber together with the top of the piston, and is equipped with components such as intake valves, exhaust valves, spark plugs, etc.
Valve mechanism: including intake valve, exhaust valve, camshaft and other components, responsible for controlling the intake and exhaust process of the cylinder.
Fuel supply system: responsible for injecting fuel into the cylinder in an appropriate proportion and manner, mixing with air to form a combustible mixture.
Ignition system: In gasoline engines, the ignition system is responsible for igniting the combustible mixture at the appropriate time, generating explosive force to drive the piston movement.
Lubrication system: provides lubricating oil for various moving parts of the engine, reducing wear and frictional resistance.
Cooling system: It removes the heat generated by the engine through the circulation of coolant, keeping the engine operating within a suitable temperature range.
