The engine is controlled within the appropriate speed range, which can theoretically slow down the production of carbon deposits, but there is no concept of how much this speed is. Just like we can theoretically lose weight quickly as long as we don't eat or drink, but how many days we can check whether we can eat or drink is really uncertain. Therefore, many people do not know what kind of speed range to control when using the car, so as not to count low speed driving.
Today I will talk to you about this problem.
In fact, carbon deposition is the sequelae of engine burning gasoline, although burning gasoline can do work to provide power but will produce carbon deposition. And carbon deposits are inevitable, as long as it is an internal combustion engine. Once the carbon deposit increases to a certain extent, it will directly affect the fuel consumption and power level of the vehicle, and even the phenomenon of knocking will occur. But carbon deposition is not an insoluble "disease", repair shops have many ways to clean up carbon deposits, commonly used is to give the engine a hanging bottle.
However, after a long time of carbon deposition, it will become very hard and difficult to remove, and the method of playing the hanging bottle cannot completely remove the carbon deposit and even corrode the cylinder cylinder piston. The simplest and crudeest way is to take apart the engine to clean up the carbon deposits, but doing so will destroy the airtightness of the engine, and no one will do it unless necessary. In fact, carbon deposition is inevitable, and we can minimize the generation of carbon deposit by controlling the speed of the engine when using the car.
So what range is the engine speed appropriate? Is it all up to 3000 rpm?
In fact, the engine is not a low-speed driving depends entirely on the gear state of the vehicle at that time, especially the manual transmission of the car. If you hang up the gear, feel the engine jitter and refueling is dull, it is definitely a low-speed driving, and it is most likely to produce carbon deposits at this speed. If the automatic car is not well controlled by the accelerator, it will also have a low speed driving situation, which is the feeling that it cannot add fuel. Different cars have different engine power and torque, and the value of low speed is also different.
For example, Toyota Vios, more than 2 gears as long as it reaches 1500 turns up will be very smooth, this speed under the engine will not appear refueling sluggish or shaky situation, so for this car below 1500 rpm is a low speed, if often in 1500 rpm some driving is very easy to cause the engine to burn insufficiently to produce carbon deposits. But Buick Yinglang in the 1500 rpm when the engine is really too meat fuel no power, for the Yinglang car is in the 2000 rpm time to drive up smoothly, no matter which car does not need to 3000 rpm to reduce carbon deposits.
This is mainly because the Yinglang displacement is only 1.0T, and the engine power is not enough when the turbine is not working properly, it is very easy to burn insufficiently, so this car I think the speed of 2000 rpm is not a low speed. But once the turbo is involved, even at high speeds, it can reach 120KM/H with only 2500 revolutions. On the contrary, Vios needs 3500 rpm to arrive, and 3500 rpm is not high for Vios.
So how much engine speed is not easy to produce carbon deposition specific analysis, as long as your car does not appear on a critical point of speed does not appear jitter to open the refueling smoothly then this speed can be used as a "gold standard" to reasonably adjust the gear, reasonably maintain the speed, below this speed is low speed, when driving as far as possible to maintain a slightly higher speed will not burn more oil, long-term past can make your car have a different power experience.
