Engine cold run-in (engine cooling period: an indispensable process in future cars) When we mention cars,DigiPlus we usually think of its speed, power, appearance and function.However, we may overlook the most important part of the car - the engine. The engine is the heart of the car, and it drives the whole vehicle. However, before you can use the car, the engine needs to go through a very important process, that is, "cold run-in". What is cold run-in? Cold running-in means that the new car engine needs to run in a cooled state for a period of time after the first start. This process usually takes hours or hundreds of kilometers to travel. In this process, the engine will not reach the normal operating temperature. Through this process, the parts inside the engine begin to adapt to each other and further run in. Why do we need cold running-in? The engine is composed of many moving parts, such as pistons, valves and crankshafts. Each component has a very small working gap, allowing its relative movement.These working gaps must be gradually reduced during the running-in process, so that the matching between the parts is closer and more accurate, so as to achieve the best work efficiency. In the process of engine manufacturing, the manufacturing and tooling accuracy of each part cannot be 100% perfect. With the gradual grinding of the parts, its working gap will gradually decrease, thus reducing unnecessary wear and friction in the engine. After the run-in, the output power and fuel efficiency of the engine will be better. If it is not cold-adhed, the working gap of the parts will be too large, which may lead to wear and premature failure. How to carry out cold running-in? The time and driving distance of cold run-in will vary depending on the engine type and manufacturer. Usually, the owner can continue to run for 10-20 minutes after starting the engine for the first time, wait for the water temperature to reach the set temperature, and then drive in a low-load state.It is recommended to carry out this process for about 1,000 kilometers, strictly following the manufacturer's regulations or the service manual. During this process, long-term high-load or high-temperature driving should be avoided. The throttle, transmission and brakes can be operated in a gentler posture to ensure that the engine has an appropriate running-in time. It should be noted that when the engine is working in a cooled state, the risk of oil film failure increases. Therefore, special attention should be paid to the use and replacement of engine oil to ensure the full lubrication of the oil film and avoid premature wear and failure. The role in the future car. In the future, the car engine will continue to develop and evolve. Many manufacturers are researching and exploring new engine technologies, such as hybrid power, electricity, hydrogen fuel cells and autonomous drive. These new technologies will bring more efficient and reliable engines.However, no matter what kind of technology the future car engine is, they need to go through a cold run-in process before it is first started and used. Whether it is a traditional internal combustion engine or a new hybrid or electric motor, cold run-in has become one of the necessary methods for engine use and self-protection. The process of engine cooling period is not only a necessary part of car maintenance, but also an important guarantee for driving safety and vehicle life. Summary It is very important for any car owner to understand the necessity of engine running-in. It can not only improve the performance of the car engine, but also make the car maintain an efficient and stable state of four-wheel power at all times during high-speed driving and long-distance travel. Therefore, when starting for the first time after buying a new car, please always pay attention and follow the advice of the car manufacturer.The running-in process, and 100% inspection of the engine is carried out in each maintenance inspection to maintain the long-term fresh state and extended life of the car.
