engineLack of oil (the impact of low engine oil on international trade databasethe vehicle - brief analysis) In car maintenance, the importance of engine oil is self-evident. The main function of engine oil is to form a lubricating film inside the engine to reduce friction between metal parts. At the same time, it can also help dissipate heat and remove dirt in the engine. However, in frequently maintained cars, it is sometimes found that the oil level is very low, which indicates that the oil is insufficient. So, what is the impact of insufficient engine oil on the vehicle? 1. When the lubrication is insufficient and the engine oil is insufficient, the lubrication film becomes thinner, and the friction between the metal parts will increase. At this time, the parts in the engine are easy to wear out, and the quality will also decline. Excessive wear will lead to poor energy conversion between parts, thus affecting the performance of the engine, making it gradually aging and unstable.Two. The oil with reduced cleaning performance also has another function, which is to clean the exhaust gas inside the engine. The soot, particles, moisture and other dirt produced by the engine will adhere to the interior of the engine, seriously affecting the normal operation of the engine. If the oil is insufficient, the cleaning ability will decrease and the dirt will accumulate, resulting in a decrease in the heat dissipation capacity of the engine, thus increasing the wear of the machine parts and the fuel consumption. 3. When the failure oil is insufficient, the internal wear of the engine will intensify, and the piston and crankshaft will lose lubrication, so the lack of oil, which increases the wear resistance, will also lead to distortion and deformation of casting, thermal deformation and other processes, and then wear. Failure to repair these damages in time will cause failure. For example, if the wear of the cylinder block is serious, it will cause the wear of the cylinder block, resulting in friction between the parts.Service, causing black smoke from the engine, engine oil leakage and other faults, which may lead to difficulties in starting the engine, insufficient power of the vehicle or frequent alarms 4. Changing emissions Some people think that lack of oil will only affect the vehicle itself, but in fact this is incorrect. When the oil is insufficient, the exhaust system will increase the emission of pollutants. The main function of engine oil is to reduce the friction inside the engine. Excessive use of engine oil will increase the loss of energy, which not only reduces the performance of the car, but also increases the emission of yellow smoke, which has a negative impact on the environment. 5. Economic loss When moisture enters the oil system, the oil pressure and temperature may increase. This will lead to oxidation and foaming of the engine oil, thus exacerbating the wear of the engine. Regular inspection of insufficient oil will not only reduce the service life of the engine, but also add additional costs to the maintenance of spare parts.In a word, the lack of engine oil has a great impact on the vehicle, from insufficient lubrication to the decline in cleaning performance, from causing internal engine failure to changing emissions and many other aspects. Therefore, routine oil inspection for each vehicle to ensure that each addition of oil can reach the standard amount, and timely maintenance can reduce fuel consumption and extend the service life of the engine.
