How to benchmark import export performance

Engine hot car (sharing engine hot car skills,How to benchmark import export performance start the car quickly!) When it comes to the engine of a car, I believe everyone is familiar with it. As the heart of the car, the engine is particularly susceptible to cold air in winter. At this time, it is not uncommon for turtle speed to drive, start difficult, or even start failure. So how to heat the engine up the car, shorten the start-up time, and make the car run better has become a skill that needs to be mastered in winter driving. 1. The role of engine hot car First of all, let's understand the function of engine hot car. In the low-temperature environment of the engine, the viscosity of the lubricating oil increases, the viscosity of the coolant decreases, the air density increases, and the resistance increases.Therefore, before starting the engine, it needs to be preheated for a certain period of time to gradually heat up the parts of the engine, the coolant gradually flow, and the viscosity between the parts of the engine becomes smaller, making it easier to start and reduce the damage to the engine. The preheating time of the engine depends on the current temperature and is expected to take 1-5 minutes. Normally, the engine can be started when it reaches more than 50℃. Two. Use special engine oil. Because in cold weather, the importance of lubricating oil to the engine increases, we need to use special oil to improve the starting performance. When buying engine oil, you should choose the oil specifications suitable for the current temperature, instead of blindly choosing high-standard oil, because too thick will affect the heating speed of the engine, and too thin will reduce the natural protection ability. In addition, when changing the oil,A higher level of oil, such as fully synthetic oil, should be selected, because this oil can always show good lubrication effect at lower temperatures, has good wear resistance, and can also make the engine more stable in cold environments. 3. Routine inspection and maintenance of cars are essential for daily inspection and maintenance. It can not only avoid various faults, but also improve the performance of the car. Therefore, checking and processing tires, brakes and other parts in advance will also have a certain optimization effect on the thermal start of the vehicle. In addition, it is also crucial to keep the car clean. In winter, the external body and windows may be frozen. It is recommended to use professional de-icing agent for treatment and regular car washing. Because too much dirt on the surface of the vehicle will affect the engine exhaust and heat dissipation, which will prolong the hot start time.Four. Correct start-up skills. In the process of engine heating, the correct start-up skills are also very important. First of all, you should put the Gear into idle gear and release the brake. Then, slowly turn the key to make the engine start working. If you find that the engine fails to start, you can pause for a few seconds and try to start again. Before hot start, it is recommended to press the throttle before the vehicle starts to inject enough fuel into the engine, which can make the combustion more thorough and accelerate the engine heating process. However, it should be noted that continuously stepping on the accelerator will cause the engine coolant temperature to rise too fast, which may damage the engine. 5. Attention points in the process of engine heating After the engine is completed, you can listen to the change of the engine sound to confirm that the engine has been hot. If the engine is heated for too long, more fuel will be wasted, and willIt affects the service life of the engine. During short-speed driving, you should not step on the accelerator for too long. In addition, during the heating process, it is necessary to raise the throttle slightly to keep the speed at 1500 rm/minute until the engine temperature stabilizes and the throttle returns to the normal position. Generally speaking, the heating process of the engine is not complicated. It requires a certain amount of time and correct operation skills. A reasonable heating process can reduce the probability of car failure, improve the service life of the car, and make your driving experience smoother.
