How to evaluate supplier reliability

Is it normal for the engine to burn hands?How to evaluate supplier reliability This seems to be an easy question to answer. Actually, it's not. Car owners have their own views on this problem. Some people think it's normal to burn hands, while others think it's abnormal. So, is it normal or a problem for car engines to burn their hands? This article will analyze the temperature of the car engine, as well as the causes and possible risks of engine burning. First of all, we need to be clear that the parts of the engine will generate heat during operation, so the surface and nearby areas of the engine will become very hot.The working principle of the engine determines that its temperature is dozens of degrees or even hundreds of degrees higher than the ambient temperature, so heat is inevitable. Usually, burning hands is normal, especially when the closer you get to the core of the engine, the hotter it is. After all, the engine will run down at high speed while the vehicle is driving. At this time, the speed increases, and the oil and air flow into the engine will also increase. Combined together, it means that the fuel in the engine burns faster and the energy is converted faster. When the engine is running, it should divergent to the radiator to maintain the temperature. If the engine temperature is too high, it is enough to cause damage. However, this is a threat when the engine emits heat and temperature beyond the conventional range. The temperature of hot hands will vary depending on the engine parts, operating status and external temperature, but some dangerous temperature prompts are common.If the car's thermometer mark points to the red range, or the spark plug sends a wrong signal, it means that the engine has overheated. At this time, it is recommended to shut down the vehicle immediately, stop the engine, and seek professional help. So, why does the engine overheat? There are many reasons that may lead to this problem. Here are some common reasons: 1. The engine coolant is insufficient or no coolant. In this case, the heat is not accurately distributed and emitted. The most common reason is leakage in the cooling system, or leakage of coolant. Two. Camshaft deformation. This is an uncommon situation, but it can also occur when running at high pressure or accelerating. 3. Water pump malfunction. The water pump drives the coolant according to the water pressure. If the water pump fails, it will affect the distribution and heat dissipation of the coolant, causing the engine to exceed the lower limit of heat.Four. The engine is obstructed. This may involve multiple aspects, such as engine filter blockage, oil pump failure or insufficient pressure from the oil pump, oil filter blockage, etc. However, the burning of car engines should not be a problem for most car owners. This is normal when the engine surface is only slightly hot and the vehicle can maintain a uniform speed and acceleration. However, if you feel overheating or the car's trottle response is poor, it may indicate that there is a problem. In summary, we can conclude that it is normal for the engine to burn hands, especially when running at high acceleration and high speed, even if it is higher than the ambient temperature, it is not considered overheating. However, once you feel that the engine is overheating, any indicator light is on, or an abnormal problem is found, it should be dealt with in time to prevent engine loss and other risks.At the same time, it is also necessary to carry out regular car repair and maintenance, check the coolant, replace the filter, etc. This will help the heat to be better decomposed and dissipated, ensuring that the car's engine is in the best condition.
