There are several reasons why diesel generators cannot start automatically, which may lead to such problems. The most common scenario is that you have not set the control to automatic. You can go back to the randomly assigned equipment manual 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, and prolonged operation under light loads may lead to wet accumulation. The result forces the engine to operate at the required temperature. The signs of wet accumulation indicate the presence of blue oil, and if you also notice excessive consumption of lubricating oil, this may also be a signal of wet accumulation. To avoid wet stacking, it is recommended that you operate the diesel generator with at least a load. This will bring it to the required temperature to completely burn the fuel.

2. Burning excess fuel

This is a problem with a diesel generator, it will really leave a big dent in your pocket. Burning more fuel than required for a generator is a problem that needs to be solved as soon as possible, but how do you know if your generator is burning excess fuel? Black smoke is a sign. If the tip of the fuel injector is worn, this situation will occur. Even if the generator is idling, worn fuel injector tips can cause fuel to flow into the cylinder. To solve this problem, you need to replace the worn fuel injector tips.

3. Leakage

Leakage is also another common generator issue. There are three common types of leaks: fuel, coolant, and lubricating oil. Every leak will have a very adverse impact on the performance of diesel generators. Due to factors such as rising temperature and accumulation of moisture, leaks are bound to occur. To avoid leakage, regular maintenance should be carried out. For example, all hoses should be replaced after two years. According to the frequency of use of the generator, you can replace it before the specified time. That's why it's wise for you to adopt regular maintenance checks. In addition, gasket failure can also lead to leakage. Sometimes, leaks may occur, and due to a malfunction in the fuel gauge, you may not be worried. These instruments may get stuck and catch you off guard. It is best to manually check the fuel level.

4. Overheating

Some diesel generators may become hot after prolonged use. However, if you notice an abnormal temperature rise, 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 low, it needs to be refilled. In addition, before starting the generator, you should regularly check the coolant, lubricant, and fuel levels. Most people only check the fuel level and are unaware that the other two are equally important for the normal operation of diesel generators. The low coolant level is mainly caused by leakage.

5. High fuel oil level alarm

Does your high oil level alarm sound frequently? Perhaps I'm worried about what might be the problem. 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. Due to fuel expansion, the alarm may be activated. This may also occur on hot sunny days. You can turn off the alarm or manually reset it.
