The main parts and components of a truck engine include the following parts:
Cylinder block: The cylinder block is the foundation of the engine and carries other parts. It is usually made of cast iron or aluminum alloy and has multiple cylinders inside.
Piston and connecting rod: The piston moves up and down in the cylinder, and the connecting rod converts the linear motion of the piston into the rotational motion of the crankshaft, thereby driving the vehicle forward.
Valve system: Including valves, camshafts, valve springs, etc., to control the entry and exit of fuel and air.
Fuel system: Including fuel injectors, fuel pumps and fuel filters, responsible for spraying fuel into the cylinder and providing pressure.
Cooling system: It consists of a water pump, radiator, water pipes and thermostatic valves to keep the engine temperature within an appropriate range.
Crankshaft and camshaft: The crankshaft converts the linear motion of the piston into rotational motion, and the camshaft controls the opening and closing of the valve.
Valve system: Including valves, camshafts, valve transmission groups, etc., to ensure the entry of fresh gas and the discharge of exhaust gas.
Lubrication system: It is composed of oil pump, oil filter, etc., which reduces friction and prolongs engine life. Starting system: It is composed of starter, starting relay, etc., which helps the engine start.
