Many car owners say that after car has been driven at high speed, it feels like car's power has improved and it runs more smoothly. Is this psychological impact of car owners, or has power of car really improved? Let's follow the editor to find out.
In fact, feeling that car's power has increased after driving at high speed is not a psychological effect. The car's power has actually increased and it has become easier to drive. The reason car drives better after driving at high speed is because driving at high speed can clean up carbon deposits. We all know that every car has carbon deposits to one degree or another, and long-term bad driving habits and low-quality gasoline cause carbon deposits in engine. When there is too much carbon deposits in a car engine, it not only causes engine knock and oil burning, but also affects engine power and fuel consumption of car.
When vehicle is running at high speed, vehicle's engine has a large intake air volume and a high air intake rate. The high speed airflow can remove some of carbon deposits in engine, so car's power will also be improved. However, running at high speed can only remove some of carbon deposits, and to remove all carbon accumulated over years, you still need to thoroughly clean car engine, this is most direct and effective way.
In fact, in addition to carbon deposits in engine, there are many places on car that also form carbon deposits. First, car's air intake system, such as throttle bodies, intake manifolds, etc., can have carbon deposits. The throttle valve regulates amount of intake air. When there is too much carbon deposits, it can affect throttle valve opening, resulting in insufficient intake air.
The second place where deposits can form in a car is fuel system, and part where deposits can form in fuel system is mainly fuel injectors. When there is too much carbon in fuel injector, it will block needle valve and fuel injector valve port. This will not only affect size of fuel injection, but will also lead to a decrease in power performance of car. The exhaust system occupies third place in car in terms of carbon deposits, and three-way catalyst is most prone to carbon deposits in exhaust system. When there is too much carbon deposits, it will directly lead to failure of three-way catalytic converter.
It can be seen that carbon deposits are everywhere in cars, and harm it causes is very great. Therefore, when you normally drive, in addition to regularly cleaning engine of carbon deposits, you must also learn how to prevent deposits in engine. First of all, when refueling, you need to choose high-quality fuel from regular channels, because quality of gasoline will also affect formation of soot, so when refueling, you need to choose ordinary gas stations!
Secondly, do not leave car idling for a long time. Prolonged idling does not contribute to engine heating. At low engine temperatures, gasoline will slowly evaporate, which will accelerate formation of carbon deposits. In addition, you must have good driving manners, do not press the accelerator and brakes, otherwise it will easily lead to soot.
If you can complete above steps, then carbon in car will not come to your door, so take a small notebook and write it down.
