The maintenance of automobile tires is often ignored by us. However, maintaining proper tire pressure can effectively improve driving safety, comfort and better fuel efficiency.
No matter what type of car, good air pressure can help you save fuel and help you still have good safety and driving comfort in rainy and snowy weather.
Jinan Benz automobile maintenance thinks that since the tire is so important, it is very difficult to detect the tire pressure. The answer is often different from what you think. We only need a tire pressure monitor and a good inflation pump, which are available in any car maintenance shop.
Choose a standard pressure gauge, which is available in most auto parts stores and is very cheap. These are enough. In particular, it is unnecessary to buy a digital pressure gauge. If it is a digital pressure gauge, it will be a very bad thing without power. Although it is convenient for you to check, sometimes you will give up because you can't find the battery Test the tire pressure. Moreover, the standard pressure gauge can be easily placed in the glove box of your car, and at the same time, avoid the trouble caused by the ultra-low price gauge. There is also a barometer on the inflation pump, but this is often inaccurate, so there is its own meter to ensure that the car tire pressure is normal. The air pump can be found in the car, and some of them are found in the roadside maintenance plant or gas station.
The exhaust pipe of the vehicle emits white smoke, which is serious when the car is cold, and will not emit white smoke after the car is hot: fault judgment: false fault. Cause analysis: This is because the gasoline contains moisture, and the engine is too cold. At this time, the fuel entering the cylinder is not completely burned, resulting in fog point or water vapor to form white smoke. In winter or rainy season, white smoke is often seen when the car is first started. It doesn't matter, once the engine temperature rises, the white smoke will disappear. This condition does not require maintenance.
The engine noise is loud. When the vehicle steps on the accelerator pedal in place, there is a "boom. Boom" noise. There is vibration in the engine compartment. Fault judgment: use fault. Cause analysis: lifting the vehicle, you can see that the bottom guard plate of the engine has bumping marks. If there are obstacles on the road and forced through, the engine bottom guard will be bumped. The distance between the bottom guard plate and the engine oil pan becomes closer after deformation. If the distance is too close, when the oil pan collides with the bottom guard plate during acceleration, abnormal noise will be generated and the vehicle body will vibrate.
