The number of cars in the city is large, the traffic environment is more complicated, and the average speed of driving in the city is only 60 to 80. Some car owners occasionally drive on the highway and notice some changes in the car. I used to think that cars were not driving well and were slow. After driving at high speed, why do you feel that the car drives better?
Changes caused by frequent driving on high speeds: cities are driving very slowly, and if the car stops, the fuel bill will increase and carbon will accumulate. When driving at high speed, the speed of the car is accelerated, and the speed of about 120 is maintained for a long time, the owner's throttle will become brisk, the fuel consumption will decrease, and the power of the car will become stronger. Now, many cars are equipped with ECU adaptive function, and the speed of the vehicle on the city road is very slow. The ECU driving computer automatically detects the speed of the car and changes the logic of intake, combustion and gear change according to driving habits.
The vehicle is fast at high speed, and the ECU also has an adaptive learning function, which can change the combustion speed and improve the shift logic. The owner returned to the city after driving at high speed for a period of time, the speed of the car became slower, but the ECU has not yet reacted, the driving mode has not changed, so the owner feels that the intake of the car has become larger, the speed has become faster, and it is easy to drive. After the vehicle has been driving in the city for a while, when the ECU changes its driving mode, the owner will feel as if the car has returned to its original appearance.
The benefits of high-speed driving: Because cars are always driving slowly in the city, the accumulation of carbon is increasing. Carbon deposit refers to the incomplete combustion of fuel in the engine, which is formed under the catalysis of high temperature and oxygen. This colloid is attached to the throttle and near the intake tract, which is poorly ventilated and the fuel utilization rate is improved.
First, reduce the accumulation of carbon. When the owner occasionally drives at high speed, if the speed exceeds 120ECU, the intake, exhaust and combustion efficiency of the engine will be automatically adjusted. When the engine's air intake increases, a small amount of carbon attached to the throttle is washed out, so the owner's fuel economy is reduced and the driving experience is better.
Second, extend the life of the battery. The life of a car battery is 6 to 8 years, and the longer it is used, the faster it consumes power. If the vehicle does not stop, the battery will be in a low-power discharge state, the vehicle will be parked for a month to a month and a half, the battery will be completely depleted, and it will not be able to start after ignition. Because there are more short distances in the city, the battery will not be fully charged if the driving time is less than 30 minutes each time, the battery will undergo vulcanization reaction, and the life will decrease. The owner's high-speed battery will be fully charged, extending the battery life.
Editor's note: A car that has been driving at a low speed in the city for a long time is not conducive to eliminating the accumulation of carbon and making the battery fully charged. If conditions permit, it is recommended that the owner drive on the highway for a period of time every half a month. By driving at high speeds, ensure that the vehicle reaches about 120. Only by reaching this speed can the carbon build-up near the throttle be effectively washed away. If the car has a serious carbon deposit, affecting acceleration and fuel consumption, the owner can go to the repair shop to hit the hanging bottle. In the daily car maintenance process, the owner can put part of the fuel treasure in the gasoline tank, also known as fuel additives, which can improve the carbon accumulation phenomenon and make the exhaust gas cleaner, what do you want to say?
