1. Basic knowledge of car structure - car engine
The engine is the power plant of a car. It consists of 2 major mechanisms and 5 major systems: crank connecting rod mechanism; valve train; fuel supply system; cooling system; lubrication system; ignition system; starting system.
1. Cooling system: generally consists of a water tank, a water pump, a radiator, a fan, a thermostat, a water temperature gauge and a water discharge switch. Car engines use two cooling methods, air cooling and water cooling. Generally, automobile engines are mostly cooled by water.
2. Lubrication system: The engine lubrication system consists of oil pump, filter, oil filter, oil passage, pressure limiting valve, oil gauge, pressure sensing plug and oil dipstick.
3. Fuel system: The fuel system of a gasoline engine consists of a gasoline tank, a gasoline meter, a gasoline pipe, a gasoline filter, a gasoline pump, a carburetor, an air filter, and an intake and exhaust manifold.
2. Basic knowledge of car structure - the chassis of the car
The role of the chassis is to support and install the car engine and its components and assemblies to form the overall shape of the car, and to accept the power of the engine to make the car move and ensure normal driving. The chassis consists of four parts: drive train, driving train, steering train and brake train.
1. Drive train: The power from the car engine is transmitted to the driving wheels by the drive train. The transmission system has the functions of deceleration, speed change, reverse, power interruption, inter-wheel differential and inter-axle differential, and works with the engine to ensure the normal driving of the car under various working conditions, and has good power and performance. economical. It is mainly composed of clutch, transmission, universal joint, transmission shaft and drive axle.
Clutch: Its function is to smoothly engage or temporarily disengage the power of the engine and the transmission, so as to facilitate the driver to start, stop, shift and other operations of the car.
