Installed in the chassis metal parts can be. With a period of time, the lowermost part of the wear and tear, you can put down some of the rubber band above.
Users with conditions can install tanker static grounding alarm
Under the high-voltage electric line, it is strictly forbidden to fill the tanker with fuel.
Not allowed to often use the hanging fire method. Sometimes the truck 6 x 4 spark plug will have carbon, when a cylinder of carbon is serious, the cylinder can not work normally, in order to make the cylinder can be normal operation, the cylinder outside the “hanging fire” method (the spark plug and high voltage line between the gap of 3 mm – 4 mm), in order to improve the spark plug electrode jump fire energy, so that the But the general “hanging fire” method is easy to fall off if you are not careful. If there are drips of petrol on the cylinder, a fire can easily occur. It is therefore only a temporary remedy. The correct treatment should be to clean and maintain the truck with howo fuel tank truck spark plugs in time and avoid using the “dangling fire” method as far as possible.
The root cause of automatic stalling when the accelerator pedal is released while the engine is running or while the vehicle is running is that the engine is not easily stabilized at idle speed from non-idle speed to idle speed, so it immediately stalls. The specific reasons are: faulty accelerator pedal; crankshaft position sensor and camshaft sensor signals are not synchronized; faulty fuel oil pressure; incorrect control unit signals; incorrect injection timing, etc. The focus should be on checking the change in value from non-idle speed to idle speed.
The phenomenon of insufficient engine power is basically normal when the engine is running without a load, but slow acceleration when running with a load, uphill powerlessness, accelerator pedal to the end still feel the lack of power, the speed of the same, can not reach the maximum speed. The phenomenon of poor engine acceleration is that the engine speed cannot rise immediately after the accelerator pedal is pressed, there is a hysteresis phenomenon, or the engine has slight fluctuations during the acceleration process.
The reason for the lack of power and acceleration of the engine is that the fuel pressure of the fuel system is too high or too low; poor injector injection; wrong sensor signal; too small injection; incorrect injection timing; low cylinder compression pressure; exhaust blockage, etc.
Cause electronically controlled diesel engine starting fault factors more, the general performance for can not start (no initial combustion) and start because of difficult. The inspection and elimination methods are as follows.
Check whether there is a fault code, if so, should be checked according to the content of the fault code.
Check whether the engine can turn when starting.
If the accelerator pedal is depressed when starting or repeatedly depressed in order to increase fuel supply, the engine speed will often increase instantaneously, resulting in increased fuel consumption of the engine.
Disconnect the accelerator pedal harness, so that the engine can enter idle, it means that the fault for the accelerator pedal is faulty.
External inspection: check the air inlet pipe for air leaks.
Fuel line inspection: check the connection status of the fuel line, the phenomenon of air intake and the quality of the fuel.
Wiring harness check: check the state of the wiring harness connection for loose phenomena or insecure plugging.
Inspection of sensors: Check for sensor failure, loose or broken wiring and crankshaft and camshaft synchronisation signals.
Check if there is a control signal for the fuel injector. If there is no control signal, the fuse, wiring and ECU should be checked and if there is a control signal, the injector spray should be checked for normal conditions.
