What To Do When The Diesel Generator Cannot Start Automatically

Sep. 29, 2021

Diesel generators cannot start automatically. There are several reasons that may cause such problems. The most common situation is that you have not set the control to automatic. You can go back and check the equipment manual that comes with it to see how to set the generator to start when needed.


1. Wet accumulation.

Wet accumulation can be defined as the accumulation of unburned fuel in the exhaust system. In addition, prolonged operation under light load may result in wet piles. As a result, the engine is forced to work at the required temperature. Signs of wet accumulation indicate the presence of blue oil. If you have also noticed excessive consumption of lubricant, this may also be a sign of wet accumulation. In order to avoid wet piles, it is recommended that you run the diesel generator with at least a load. This will bring it to the required temperature to completely burn the fuel.


2. Burn excess fuel.

This is a diesel generator problem, and it will really leave a big dent in your pocket. A generator burning more fuel than needed is a problem that needs to be resolved as soon as possible. But how do you know that your generator is burning excess fuel? Black smoke is a sign. This can happen if the tip of the injector is worn. Even if the generator is idling, a worn injector tip can cause fuel to flow into the cylinder. To solve this problem, you need to replace the worn injector tip.

3. Leakage.

Leakage is another common generator problem. There are three common types of leaks: fuel, coolant, and lubricating oil. Every leak will have a very adverse effect on the performance of the diesel generator. Leakage will inevitably occur due to reasons such as temperature rise and moisture accumulation. In order to avoid leakage, maintenance should be carried out regularly. For example, all hoses should be replaced after two years. Depending on the frequency of use of the generator, you can replace it before the specified time. This is why it is wise for you to take regular routine maintenance inspections. In addition, a faulty gasket can also cause leakage. Sometimes, a leak may occur, and you may not worry about it because the fuel gauge is malfunctioning. These meters may get stuck, and the result will catch you off guard. It is best to manually check the fuel level.


4. Overheating.

Some diesel generators will become hot after prolonged use. However, if you notice an abnormal rise in temperature, then you need to do something. Overheating is usually the result of a low coolant level. Therefore, you need to check. If the amount of coolant is small, it needs to be refilled. In addition, before starting the generator, you should always check the levels of coolant, lubricant and fuel. Most people only check the fuel level without knowing that the other two are equally important to the normal operation of diesel generators. The low coolant level is mainly caused by leakage.


5. High fuel level alarm.

Does your high fuel level alarm sound often? May be worried about what went wrong. The high fuel level alarm is a standard protocol installed on most generators to notify that the fuel tank is almost full. When the fuel tank level exceeds 95%, the alarm is activated. However, in some cases, due to the increase in temperature. The alarm may be activated due to fuel expansion. This can also happen on a hot sunny day. You can turn off the alarm or reset it manually.
