When the novices bought a new car, they heard people say that maintenance and the like, often touched their heads, how long to do maintenance, and when to do the most appropriate maintenance, small maintenance and large maintenance What is the difference? The second-in-law's monk is not at ease. Below I prepared an article about car maintenance. The so-called minor maintenance refers to the construction of replacing the engine oil and machine filter every 5,000 kilometers of the vehicle. The large maintenance refers to the construction of replacing the engine oil plus three filters for one year. "Three filters" refers to air filters, oil filters, and fuel filters. The filter, as its name suggests, is a device for filtering impurities. The "three filters" are cleaned and maintained in a timely manner. They can give full play to the performance of the engine, reduce the engine failure rate, and help extend the service life of the engine. Car Care Tips 1 Air Filters Correctly installed air filters can reduce wear on parts such as cylinders, pistons, and piston rings. It is generally cleaned every 5,000 km. Air filters must be replaced every 10,000 km. 2 Oil Filter The correct installation of the oil filter can prevent impurities from mixing into the engine oil during the use of the internal combustion engine and prevent wear of moving parts and blockage of the oil path. When replacing the oil, the oil filter must be replaced at the same time, otherwise it will affect the quality of the oil. The cycle of oil and oil filter replacement is generally 5,000 kilometers. 3 Air Conditioning Filter The air filter of the car is mainly used to filter the impurities in the air to prevent some impurities from being sucked into the engine because the car engine is a very precise component. If some impurities enter, it will cause damage to the engine. Damage, but also for the air filter, if not replaced for a long time will cause engine intake shortage, easy to make the engine's efficiency and power drop. Car air filter replacement cycle is generally 20,000 kilometers or half a year since the three filters on the car's impact so much, how to choose a good quality machine filter it? The first move: to see if the machine filter rubber ring has toughness and softness, the rubber ring that the machine filters into the oil outlet is also one of the references for judging the filter quality. We can remove the rubber ring and squeeze it by hand to feel the texture of the rubber ring. A good machine filter, the rubber ring material will be very thick, and there will be a soft feeling when you squeeze to ensure the sealing of the inlet and outlet. The second measure: to see if there is a non-return valve in the interior, whether it has a check valve is also an important basis for judging the level of a filter's quality. We can use the small tools around to identify whether the filter has a check valve structure. The mechanical filter check valve is actually a rubber cup, a very simple part, but the role is very important - it can block the oil return, to ensure that the engine can be formed in the lubrication system as soon as the engine cold start Oil, minimize engine dry grinding time. Simply put, a check valve is a device that allows the lubrication system to store as much oil as possible after the vehicle has stopped. The third measure: Put the finger into the filter and touch the inner wall to judge whether it is fixed or not. The filter will be firmly fixed inside the filter and will not be displaced when subjected to the oil pressure and the bumping of the vehicle. The oil is filtered through the filter paper. Therefore, the quality of a filter can also be judged from the degree of fixing of the filter element. The 4th move: to shake the motives to filter, to hear whether there is noise, this move is the same as the method of touching the inner wall - a good machine filter, the filter is fixed better, when the shaking does not appear parts interfere with each other Noise. Take a look inside the machine filter in the end is what? The original car maintenance has so much knowledge, surely everyone will understand after reading it. The knowledge of each part is even deeper. Of course, everyone is not an auto industry. You don't need to understand the depth. You only need to know the knowledge of car maintenance. Warm tips. There is a saying, one price, one price, it is recommended that you do not use a bad machine filter, worth more than oh, for your car, please use a good quality filter, but also pay attention to the timely replacement of machine filter.
