Engine system: Brief description and How to interpret global trade indicatorsmaintenance details The engine is the core part of the car and all vehicles, and is a key component of the engine system. Most drivers can see it directly during routine inspections before operating the vehicle, but once a problem occurs, it usually requires expertise to fix it. In this article, we will briefly introduce the engine system and its components, and discuss daily maintenance and the most common repair problems. Components of the engine system The engine system includes the following components: 1.Fuel system: It introduces fuel into the engine and converts it into energy and heat in the combustion chamber. Two. Exhaust system: exhaust gases, which are produced during combustion, and the exhaust system exhausts them from the engine. 3. Cooling system: Keep the engine operating temperature in a stable range to avoid damage to the engine due to overheating. Four. Electrical system: guide current and electricity to help the engine work normally. It includes batteries, generators, starters, ignition coils, spark plugs and switchgs, etc. 5. Lubrication system: Introduce the lubricating oil into the engine to avoid excessive wear between adjacent and each other. Maintenance and daily maintenance are the key to ensuring the normal operation of the engine system. The following are several common ways to maintain the engine system: - Regularly replace the oil and oil filter to protect the engine from excessive friction and heat.- Replace the air filter and oil supply filter to prevent impurities from entering the engine. - Check the fuel pump, syringe and fuel tank to ensure that they work well and the fuel quality is guaranteed. - Check the generator, battery and wire to ensure the normal operation of the power system. - Check the pump, radiator and coolant , ensure the normal operation of the cooling system. - Check the exhaust system, especially the exhaust pipe, at any time. Check whether it is ragged and for air leakage or other problems. - Check the belt and tire regularly to avoid the possibility of scratches and wear. Despite regular inspection and maintenance, the engine system may still fail. The following are the most common engine problems: 1. A common reason for difficulty in ignition or inability to start the engine is insufficient battery power or damaged circuit. At the same time, there may be problems caused by the fuel feeding system or oil products.Two. A possible reason for engine shaking and stopping is the failure of the ignition system or the failure of the engine fuel supply or the problem with the supercharger. 3. One of the reasons why the engine heat is too high is that the cooling system failure causes the coolant to fail to cool and dissipate normally. Four. Engine noise. Some engine noise may be caused by belts, tires or insufficient oil. Summary: If you want to maintain a healthy engine system, you must regularly check and maintain various related components. In addition, once a problem occurs, it needs to be repaired in time to prevent the problem from expanding or causing irreparable damage to the engine.
