Engine warm-up (effective engine preheating method sharing) Engine warm-up is HS code compliance for customsone of the things that every car owner must do. It can not only extend the life of the engine, but also improve the performance of the car. However, how to warm up correctly is a task that needs to be paid attention to. Next, we will introduce some effective engine preheating methods to ensure that your car can run smoothly during cold start. What is an engine warmer? Before understanding how to warm up correctly, let's first understand what engine warm is. Send in the carBefore the motive is running, various parts of the engine need to be preheated to ensure the viscosity and fluidity of the oil, so as to avoid damage to the engine and the car when starting. This process is called engine warm-up. The importance of engine warm-up. The main purpose of engine warm-up is to reduce wear when starting, improve engine performance and avoid unnecessary damage. When the engine is in a cold state, the viscosity of the oil will increase, resulting in increased mechanical wear and more serious engine wear. Warming machine can reduce the viscosity of the oil, and even under low temperature conditions, it can also play the role of oil feeding. In addition, normal warmers can also make the emissions cleaner and safer and more reliable when the vehicle leaves. The right way to warm the engine is what the owner must do. For different car models and weather conditions, different warm-up methods should be chosen.Here are some best practices for engine warm-up. Observe the warning light before starting: Before starting, first observe the engine fault light. If there is an abnormal warning, you need to find a professional to repair it immediately. Do not start the car before the thermometer reaches zero: In winter, do not start the car immediately before the thermometer reaches zero. The correct way is to turn on the car, only turn on the air circulation system, and keep the engine idling. When the thermometer reaches a certain water temperature, the engine is just at a normal operating temperature. When the water temperature meter reaches the normal water temperature, it means that the car can work normally. Don't use the idle gear to heat the car: When the temperature is low, we don't put the car in idle gear, because it will increase the wear of the engine. The correct way is to put the car in D or R gear, step on the accelerator at the same time, and let the tires run slowly until the engine runs normally.Drive out slowly: When the engine is working normally, we can drive the car gently to make the car reach a normal operating state. When you are ready to drive out of the parking lot, you should drive out as slowly as possible until the vehicle reaches normal and stable working conditions. Use downhill gear in winter: In addition, when the weather is cold, we should use the engine to accelerate to quickly increase the speed to normal. In this case, we suggest hanging the engine to low gear when going downhill so that the engine can exert maximum power. Conclusion In short, correct engine warm-up can extend the service life of the engine, improve the performance of the car, while maintaining the fresh state of the engine and reducing wear. Although the preheating methods are different for different models and different weather conditions, the general principle is that the correct engine warming method can make the owner's car more assured.Therefore, we need to learn the correct engine preheating method to ensure that the car operates normally before starting. After all, the car is an important part of our life, and we need to take care of it carefully and maintain a normal working state.
