[导读]：吸粪车长时刻处于低速行进状态，会影响车辆的保养和使用寿命。It will affect the maintenance and service life of the vehicle
It will affect the maintenance and service life of the vehicle if the vehicle is in low-speed running state for a long time.
It is easy for the engine to generate carbon deposit when the truck is in low speed for a long time. In addition, the traffic jams and signal lights in urban roads often cause the engine to stop before it reaches the normal working temperature or the higher temperature. The injection time of the engine is ahead of the burning time. At this moment, the fuel sucked in is deposited behind the valve and evaporated at low temperature, but the wax and gum in the process are gradually deposited on the valve. Over time, these substances form rough shells on the surface, and gradually grow along the shells, forming carbon deposits.
The injection time of the engine is ahead of the burning time. At this moment, the fuel sucked in is deposited behind the valve and evaporated at low temperature, but the wax and gum in the process are gradually deposited on the valve. The severe carbon deposition will affect the service life of the engine. The impact of carbon deposition on the engine is mainly reflected in the difficulty of cold starting, the idle speed of the cold car can not reach the regular speed, the cold car idling will turn off when it is severe, and the idle speed of the hot car will be low, which will also lead to the decrease of the engine power, the acceleration is not smooth, and the fuel consumption will increase; the poor exhaust emission of the engine will also shorten the service life of spark plug, oxygen sensor and three-way catalyst.
The carbon deposit can be removed by cleaning the fuel nozzle and air inlet; the cleaning of the fuel nozzle and air inlet can remove part of the carbon deposit and soften the deep carbon deposit; the addition of lubricating oil additive to the oil tank can continuously clean the carbon deposit, restore the atomization effect of the fuel nozzle, adhere to the smooth oil path and restore the power of the engine. Xiaobian thinks that the outstanding driving habits of car maintenance can effectively prevent the generation of carbon deposit; select the right car according to the manufacturer's instructions
