Many people think that they know very well about the automotive industry, but what do you know about the cold knowledge of these automotive industries? Everyone knows that Volvo is the safest car brand in the world, and the car’s seat belt was invented by Volvo Car. Until now, Volvo’s car safety technology is still in the forefront of the automotive industry. Volvo invented the seat belt, but China invented the seat belt buckle. The seat belt buckle was invented for not wearing a seat belt. It is the nemesis of the seat belt. With the continuous development of globalization, the automotive industry has long been a global cooperative industry, […]
Ignore the clarity of rearview mirror — driving safety is not guaranteedAlthough rain can keep the air moist, it also brings some troubles to driving friends. For example, many car friends complain that when it rains, the outside rearview mirror and side window are covered with raindrops, which greatly affects the rear sight.Especially under the circumstance of bad night light, the rear headlamp hits the rearview mirror to become “waste”, one is not careful easy occurrence traffic accident, safety hidden danger is very big!
9. Arbitrary addition of equipment in the vehicle — affecting driving safetyPrivate cars are the mobile home of car owners. It is understandable to pursue the comfort and luxury of riding. However, some car owners install various equipment in the car by themselves.
Eight, water tank “open pan” quick add water — cylinder crackingWhen the weather is hot, some drivers see the water tank “open the pan” phenomenon, worried about the engine temperature rise again, immediately shut off and add water.This is a mistake and it is likely to cause the cylinder head to crack as a result of sudden cold.If the water tank encountered “open the pot”, the general correct method is: immediately stop the engine to keep idle to continue cooling;Open the hood at the same time, improve the heat rate.When the temperature of the cooling water drops, turn off the engine.If the amount of cooling water is insufficient, it should […]
Bolts are too tight — permanent deformationThe tightness of the belt can improve the cooling effect of the engine. Therefore, the tightness of the fan belt is constantly increased, resulting in the over-tightness of the fan belt.Fan belts should be kept tight, as over-tightening will lead to excessive bearing load, increased wear and power consumption, as well as bending the pump shaft, elongating the belt and shortening its life.
Cooling water temperature is too low – wear down the engineWhen the weather is hot, some drivers insist that the temperature of cooling water should be as low as possible to prevent the engine from being too hot.In order to achieve the purpose of cooling down, some drivers simply remove the thermostat, these practices are wrong.Automobile engines are both afraid of heat and cold. If the temperature of cooling water is too low, fuel combustion will deteriorate, fuel consumption will increase, aggravating wear and tear, engine oil viscosity will increase, and engine power will decrease.The test shows that when the temperature of cooling water is 40-50 degrees Celsius, the engine […]
