How to understand re-export regulations

Engine system composition: The How to understand re-export regulationsengine system is composed of various parts and subsystems. In modern cars, the engine system usually uses an internal combustion engine. It is mainly composed of different types of components such as gasoline, diesel engine or electric motor. The engine system consists of many different systems, which have different functions but are interrelated to make the engine run normally. It can be mainly divided into the following parts: fuel system, ignition system, cooling system, lubrication system, exhaust system, etc. Fuel system The fuel system is a system that refers to the engine to provide fuel. It is mainly composed of fuel tank, oil pump, fuel injector, etc.The fuel tank is a part that stores fuel, and the oil pump is usually composed of a diesel pump and a gasoline pump. The function of the fuel pump is to raise the fuel from the fuel tank to the engine fuel system. The fuel injector is a component that discharges fuel into the fuel injection system of the engine. The main function of the fuel system is to supply fuel to the engine so that the engine can operate normally. Ignition system Ignition system is the part that ignites the fuel to make the engine run normally. It mainly includes ignition plug, ignition coil, ignition control unit, etc. The ignition plug is the core component of the ignition system. It is mainly responsible for transmitting current to the ignition coil, and the ignition coil is responsible for converting the current into high voltage. The ignition control unit is responsible for controlling the timing of ignition and the high-voltage electrical signal at the time of ignition to ensure that the engine is ignited at the right time and the fuel is processed in the correct way.The function of the cooling system cooling system is to take away the residual heat generated in the engine and avoid overheating damage to the engine. The cooling system is mainly composed of water tank, water pump, heat sink, fan, etc. The water tank is a component used to store coolant. The function of the water pump is to bring the coolant into the engine through circulation. The heat sink and fan are responsible for emitting heat from the engine. The function of the lubrication system is to provide lubrication for the engine. It is mainly composed of lubricating oil pump, oil filter, oil cooler, etc. The main function of the lubricating oil pump is to introduce the oil into the lubrication system. The oil filter is used to remove impurities in the oil. The oil cooler can effectively reduce the temperature of the oil and prevent the oil from deteriorating at high temperatures. The lubrication system plays a very important role in ensuring the stable operation of the engine and prolonging its life. Put in orderThe main function of the gas system exhaust system is to discharge the exhaust gas from the engine while reducing the pollution of the exhaust gas to the environment and other artificial facilities. The exhaust system is mainly composed of two parts: the exhaust pipe and the catalytic converter. The exhaust pipe is responsible for discharging the exhaust gas, and the catalytic converter is responsible for purifying the harmful substances in the exhaust gas to achieve environmental protection. In a word, the composition of the engine system is very complex, and it is also an important part of the car. The mutual collaboration of the fuel system, ignition system, cooling system, lubrication system and exhaust system is extremely important. Only when they perform their respective functions and coordinate their work can the car's engine operate normally and maintain excellent performance. The maintenance of the engine system is very important. If there is a problem with any of these parts, it will affect the overall work efficiency of the car, resulting in a decline in the performance of the car and even making it unavailable.Therefore, a qualified driver should have a basic understanding of the engine system of the car in order to solve problems in time and ensure the stability and safety of the car.
