A friend of the driver's sewer car may find that the exhaust pipe has a red hot, hot, etc. in the middle of driving, then driving the vehicle in such an environment, if the high temperature exhaust pipe is encountered in some relatively easy When burning explosives, it is very easy to cause a fire, and the consequences are not dare to think. So how should we deal with this situation?
If the diesel engine of the sewage suction truck has a large forward angle of fuel supply, the compression pressure and temperature in the cylinder will be relatively low at this time, and it will directly affect the subsequent combustion performance. The diesel engine will appear to burn completely or early. In the case of more fuel, black smoke appeared. In addition to the large advancement angle of fuel supply, it can lead to the occurrence of diesel engine failure and black smoke. In addition, the lack of diesel power, combustion noise, increased fuel consumption, leakage, humidification, and other phenomena of the exhaust nozzle . When the temperature of the exhaust pipe is relatively high, there is a possibility of red burning.
If the fuel injection vehicle's fuel supply advance angle is too small, then the fuel injection time into the cylinder is or misses the optimal time period, it will also make the post-combustion of the diesel engine increase, and a large amount of fuel will not be fully burned. The cylinder was exhausted and diesel engine smoke was also found. And some of the above failures occur. First of all, if we have already determined that the black smoke of the diesel engine and the burning of the exhaust pipe are caused by the wrong timing of the fuel supply, only after adjusting the correct angle of the fuel supply advance angle, The mouth has failed.
Some of the suction pump plungers or the outlet valve of the suction pump have a more serious wear and tear. This will cause the pump oil pressure of the fuel injection pump to drop, making the injector and injector relatively late in the build-up pressure. After the increase in post-combustion, fuel combustion is not sufficient, so the diesel engine will appear black smoke. Failures of the oil valves and plungers of some individual cylinders also caused the diesel engines to emit black smoke. If most of the fuel injection valves and plungers of the fuel injection pump have serious wear and tear, then it is not just a serious black smoke condition. Difficulty in starting the diesel engine, increasing the amount of lube oil, insufficient power of the diesel engine, and row The temperature of the gas is high, the exhaust pipe burns red and so on.

Electric vehicle (BEV) refers to a vehicle that is powered by an on-board power source and uses an electric motor to drive its wheels, meeting various requirements of road traffic and safety regulations. Due to its relatively small impact on the environment compared to traditional cars, its prospects are widely optimistic.
The main difference (difference) between pure electric vehicles and gasoline vehicles lies in the four major components: drive motors, speed controllers, power batteries, and on-board chargers. Compared to gas stations, it consists of a public ultra fast charging station. The quality difference of pure electric vehicles depends on these four major components, and their value also depends on the quality of these four major components. The use of pure electric vehicles is also directly related to the selection and configuration of the four major components.
