What are the common causes of automatic flameout of coal yard sweeper?

The coal yard sweeper will suddenly turn off automatically during the whole use process, which is not only very dangerous, but also may be accompanied by the situation that the car cannot be hit after the engine is turned off. In this case, drivers and friends should first not panic, but calmly find out the reason why the coal yard sweeper automatically turns off, and find a solution according to the reason. So what are the common reasons for the automatic flameout of the coal yard sweeper? Let's learn from the manufacturer of Xerox Heavy Industry Coal Sweeper:

1. Check whether the vacuum in the air inlet pipe of the sweeper leaks;

2. Idle speed instability caused by improper idle speed adjustment, dirty throttle body and poor idle speed control system;

3. The fuel system of the sweeper is unstable, such as excessive wear or poor contact of the sweeper system, or blockage of the fuel pump filter screen;

4. The EGR valve of the sweeper is blocked or the bottom leaks;

5. The fuel pump relay, EFI relay and ignition relay of the sweeper are not working normally;

6. Poor contact between the fuel pump drive circuit and the fuel injector drive circuit of the sweeper;

The combustion system of the sweeper doesn't work well. For example, the high-voltage spark is weak, the spark plug is used for a long time, the incineration timing is incorrect, the incineration coil is not connected correctly, or the turn-to-turn short circuit occurs in a hot state, resulting in no high-voltage spark or weak high-voltage spark, poor contact of low-voltage lines, intermittent grounding due to damage of insulating glue, and poor grounding.

The above are the common reasons for the automatic flameout of the coal yard sweeper compiled by the manufacturer of Xerox Heavy Industry, and it is convenient to solve the problems encountered in the daily use of our coal yard sweeper.
