"Refueling" and "slow start" startup methods abound in real life. There are also drivers waiting for a red light, whether it is stopped at the parking line or a green light, they will start slowly. The owner may be driving slowly for safety, and the owner of the car behind will often tease the car in front. There are also drivers who run like arrows immediately after the green light is on. The owner may have the idea of adding traffic light time for the follow-up car, but who is hurting the car with the driving method of pumping and slowly starting? Don't wait for the car to hurt.
The so-called "slow start" must refer to a car that gently steps on the accelerator while driving and has a relatively slow speed. There are many such cars on the street, but in fact, if you drive at such a low speed for a long time, it will hurt the car. From a safety point of view, slow-starting low-speed driving, easy to observe the road conditions around the car, even if it encounters unexpected situations, there is enough time to react, but from the engine point of view, long-term carbon will accumulate in the engine, improve the failure rate of the engine. When driving at low speed or idling for a long time, the gasoline and gas mixture in the engine cylinder is not fully burned, and the interior is easy to accumulate carbon, and after a period of time, the engine may have various failures.
"Heavy fuel" high-speed driving, to be precise, is the appropriate high-speed driving. As long as we use cars, the engine will accumulate carbon, but the amount of carbon accumulation depends largely on our driving habits, and the low-speed driving of "slow start" will be aggravated, and the high-speed driving of "heavy refueling" will slow down the accumulation of carbon. Under the premise of ensuring safety and abiding by traffic rules, the car is driven at a high speed, so that sufficient air enters the cylinder and is fully burned with fuel in the cylinder. High temperature combustion can clean part of the carbon, in addition to the high speed vibration of the engine, it can also vibrate the carbon deposit attached to the surface of the valve and spark plug, which is beneficial to the car.
At this time, some car owners may worry that if they start with heavy fuel, the speed will suddenly rise from about 800 rpm to three or five thousand rpm, and the high-speed engine as usual cannot withstand it. This is not the case. The engine is not as fragile as we think. The high speeds caused by heavy refueling and ground oil will not cause damage to the engine. When the actual engine speed exceeds the rated speed, the automotive electronic control system will limit the oil supply action and protect the engine by maintaining the engine at a certain limit speed. In addition, the engine is not as fragile as we think. Before each engine is officially assembled into a car, most of them undergo rigorous experiments to ensure that the engine runs stably.
Therefore, after the above analysis, the proper refueling and slow-start driving mode will not cause harm to our car, but a long period of slow-start low-speed driving will indeed hurt the vehicle, worsen the engine carbon deposit, improve the failure rate, and make the car injured, so that we must have good driving habits in daily driving and process, rational use of slow start and violent refueling. In any case, we must ensure that the driving and safety are carried. Finally, Da Plutonium wanted to ask everyone a question, always cheering. No problem for AT and manual transmissions, but can a car with a CVT transmission withstand such hardship? Please leave your comments!
