With the increase in the number of cars, everyone's attention to the car is definitely getting higher and higher, and it is no longer limited to the brand and appearance of the car, many car owners and friends are more concerned about the inside of the car, because they always want to know more about the knowledge of the car, so that they can make their car more resistant.
For most people, when using a car, the most important thing is the car engine, always thinking that you can find a particularly good way to maintain the engine, so that the engine is kept in a good state, so that when you use the car later, you don't have to worry about the engine will have too serious failures, so basically you will choose to change the oil. The owner of the car changes the oil of the car a little better, gives the engine a better lubrication effect, and makes the engine run more smoothly.
However, in addition to changing the oil, some drivers will say that running high speed can also maintain the engine, so can the high speed really maintain the engine? Experienced repairmen today come and tell you the truth.
Owners who often run high speed can find that the car is more fuel-efficient, because in the state of high speed, the engine can exert sufficient power, at this time, the combustion of fuel can also be more sufficient, so the state of the car will be very good, not only can save fuel, but also the power of the car can also feel significantly improved.
But this can not play a role in maintaining the engine, because the car is driving on high speed, there will always be some emergencies, in the emergency situation and the need for sharp braking, from high speed to low speed of a gap, will lead to engine power instability, a large amount of carbon deposition; and such operation, in fact, the impact on the engine is also very strong, so do not feel that running high speed can maintain the engine.
In fact, the normal maintenance of the engine,
Car owners need to pay attention to the following 6 points.
1. Use the appropriate quality grade of lubricating oil. The selection standard is subject to no lower than the manufacturer's requirements, of course, it is not the higher the grade, the better, the choice of engine oil suitable for their own model is the most critical.
2. Replace the oil and filter element regularly. Any quality grade of lubricating oil, the oil quality will change during use. After a certain mileage, the performance is unstable, which will bring various problems to the engine. In order to avoid the occurrence of failure, the oil should be changed regularly in combination with the actual use of the oil, and the oil amount should be moderate (generally the upper limit of the oil scale is good).
3. Keep the crankcase well ventilated. Most gasoline engines are now equipped with PCV valves (crankcase forced ventilation devices) to promote engine ventilation, but contaminants in the blow-through gas will deposit around the PCV valve, which may clog the valve. If the PCV valve is blocked, the polluting gas flows in the reverse direction into the air filter, contaminating the filter element, reducing the filtration capacity, resulting in increased fuel consumption, increased engine wear, and even damage to the engine. Therefore, the PCV must be maintained regularly to remove contaminants around the PCV valve.
4. Clean the crankcase regularly. During the operation of the engine, due to various things, it will form sludge. When the amount is small, it is suspended in the oil, and when the amount is large, it precipitates from the oil, blocking the filter and oil holes, causing engine lubrication difficulties and causing wear. Therefore, we need to go to the auto repair shop regularly to clean the crankcase and keep the inside of the engine clean, so that it has more space, can better play its performance, and make the car run more smoothly.
5. Clean the fuel system regularly. Fuel in the transportation process will inevitably have impurities involved, and the fuel through the oil supply to the combustion chamber in the process of combustion, will inevitably form colloidal and carbon deposits, so that the fuel atomization is poor, resulting in engine shaking, knocking, idle instability, poor acceleration and other performance problems.
6. Regular maintenance of the water tank. Engine water tank rust and fouling are the most common problems. Rust and scale can limit the flow of coolant in the cooling system, reduce heat dissipation, cause the engine to overheat, and even cause engine damage. Therefore, check the water tank regularly to remove rust and dirt.
In addition to the daily maintenance of the engine-related system, the cleaning of the engine itself also needs to be done well, which can not only keep the engine clean, but also reduce the phenomenon of rust and other phenomena, prolong the service life of the engine, and also play an important role in car maintenance.
