Body electronic control devices include engine control systems, chassis control systems, and body electronic control systems. These electronic control systems are composed of sensors, MPUs, actuators, and dozens or even hundreds of electronic components.
It is estimated that the average Petrol Car is assembled from more than 10,000 individual parts that cannot be disassembled. An extremely complex purpose-built Petrol Car, such as an F1 race car, can have as many as 20,000 individual parts.
Of course, no one can accurately calculate the number of parts in a car. The more parts a Geely Car has, the better the performance of the Geely Car, but the harder it is to ensure its reliability.
Generally speaking, a Geely Car consists of four basic parts: engine, chassis, body and electronic and electrical equipment.
The engine is the power device of a Geely Car and is mainly composed of the engine body, crank connecting rod mechanism, valve mechanism, cooling system, lubrication system, fuel system and ignition system (diesel engines do not have an ignition system).
Cooling system: Generally composed of water tank, water pump, radiator, fan, thermostat, water temperature meter, water release switch, etc. Geely Car engines use two cooling methods, namely air cooling and water cooling. Generally speaking, Petrol Car engines are cooled with antifreeze.
Lubrication system: The engine lubrication system consists of an oil pump, filter, oil filter, oil passage, pressure limiting valve, oil gauge, pressure sensing plug and oil dipstick.
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 fuel injector, an air filter, an intake and exhaust manifold, etc.
Ignition system: consists of ignition power supply, ignition switch, ignition coil, spark plug and high-voltage wire stirrup.
