Automobile engine components are mainly crank connecting rod mechanism and gas distribution mechanism two major parts, as well as cooling, lubrication, ignition, fuel supply, starting system and other five major systems, the specific components are cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft and flywheel, etc.
The engine is composed of two major mechanisms: the crank connecting rod mechanism and the gas distribution mechanism, as well as cooling, lubrication, ignition, fuel supply, starting system and other five major systems. The main components are cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel, etc.
Cylinder inner surface is cylindrical. In the cylinder for reciprocating motion of the piston through the piston pin and one end of the connecting rod, the other end of the connecting rod is connected to the crankshaft, crankshaft by the cylinder block bearing support, can be rotated in the bearing, constitute the crank rod mechanism.
The top of the cylinder with the cylinder head closed. The cylinder head is equipped with intake and exhaust valves. Through the intake and exhaust valve opening and closing to achieve the cylinder inside and outside the cylinder exhaust. The opening and closing of the intake and exhaust valves are driven by the camshaft. The camshaft is driven by the crankshaft through a toothed belt or gear.
Depending on the vehicle, the car engine is either in the head of the vehicle, in the middle of the vehicle, or in the rear of the vehicle.
The engine is at the front of the vehicle. This is a very common engine placement. When the engine is front axle driven, the engine can be placed horizontally or vertically, or it can be arranged outside the wheelbase, inside the wheelbase or above the front axle.
Car engines need to be serviced regularly. When driving through some particularly humid or dusty areas, it is also necessary to do some inspection and maintenance of the relevant parts of the engine.
