Matters needing attention in the use of turbocharged vehicles
Turbocharged engine vehicles should run at idle speed for 3-5 minutes before starting, especially in winter or after being left for a long time, and after oil change or maintenance.
Turbocharged engines should avoid idling for a long time, and the idling time should not exceed 20 minutes. Precautions for turning off the turbocharged engine After the turbocharged engine has been running at high speed for a long time, please idle for 3-5 minutes before turning off the engine to cool the turbocharger. Otherwise, the supercharger may be damaged due to overheating.
Why does the car adopt negative pole bearing mode?
The automobile frame itself is not easy to rust, and the interference of automobile electrical appliances to radio equipment, such as automobile stereo and communication system, is much smaller than that of positive grounding of power supply. ?
On the other hand, it can reduce the complexity of the line, not only reduce the cost, but also reduce the failure rate, and the later maintenance is also less difficult. Unified standards facilitate the production, use and maintenance of automotive electronic equipment.
How often does the evaporator of the automobile air conditioner need to be maintained?
The routine maintenance time of automobile air conditioner evaporator is about/kloc-0 once a year. ?
Inspection and maintenance of automobile air conditioner evaporator include:
Check whether there is leakage with a leak detector; Clean the inside of the evaporator (usually once every 2 ~ 3 years), and remove the dust and sundries in the air inlet screen and air supply channel.
When is the appropriate time to start the cycle in the car?
Internal circulation is suitable for driving in dusty conditions, or it is necessary to quickly cool or heat the passenger area to prevent automobile exhaust or smoke from entering the car. ?
The recirculation indicator will light up and the air inside the car will circulate internally. Under normal circumstances, press this button again to switch to the external circulation mode, and the internal circulation indicator will go out and the external circulation indicator will light up.
After restarting the vehicle, the system will remember the previously set air circulation mode. Some models will automatically switch to the external circulation mode for a period of time after starting the internal circulation mode for about 20 minutes to get fresh air. ?
Driving in circular mode for a long time may make you sleepy. Car owners must regularly adjust to the external circulation mode to get fresh air.
Will the tire pressure be too low to continue driving?
If the tire pressure is too low, you can't continue driving. If the tire pressure is too low, it needs to be inflated in time, otherwise it will cause the tire to deform in waves when driving at high speed, thus accelerating the aging speed of the tire. ?
The tire is the only part of the car that touches the ground. Tires are related to the driving stability and safety of automobiles. Air pressure is very important to tires. Tire pressure should not be too high or too low. Too high air pressure will reduce the contact area between the tire and the ground, thus reducing the grip.
If the grip is reduced, it will affect the driving stability and handling of the car. If the air pressure is too low, it will lead to the wave deformation of the tire when driving at high speed, thus accelerating the aging speed of the tire. Tires are made of rubber. Rubber products will age after long-term use, so it is necessary to change tires regularly.
In general, change the tires every four years, and make sure to see the production date when buying new tires. The warranty period of tires is three years, when not in use. ?
After installing new tires, each wheel must be tested for dynamic balance to prevent the wheels from shaking abnormally when driving at high speed. If the wheels vibrate abnormally at high speed, it will affect the handling and driving stability of the vehicle. Always check the tire pressure when using the car.
