Reasons for Speed Reduction of Diesel Generator Sets During Operation

Regarding the reason for the speed reduction when using Cummins diesel generator sets, we first need to eliminate the oil circuit problem, so we need to check the low-pressure oil circuit first. Upon inspection, it was found that the low-pressure oil circuit is normal. If the oil-water separator is replaced, the situation still cannot be improved. Later on, it was thought that if there was a problem with the low-pressure oil circuit, an error would definitely be reported. So, we need to consider how to correctly use the fault of the intake pipe of the 200 kw Cummins diesel generator set. After unplugging the air flow meter, it will not lower the idle speed, but can also increase the speed (the acceleration is a bit slow).

Check the air filter of the Cummins diesel generator set to see if it is too dirty. Blow the air filter clean, install it, and test it. When the throttle is released, black smoke will appear. Even if the air filter is not installed for testing, releasing the throttle will still emit black smoke. There are still issues with other components of the intake system; I have checked the turbocharger and EGR valve, and they are all normal. When checking the intake system, it was found that the pipeline from the intercooler to the intake pipe had completely fallen off. After tightening the clamp, the problem was resolved.

Cause analysis: The air filter is too dirty, resulting in insufficient intake air flow. The intake air flow measured by the air flow meter is low, and the ECU limits the oil quantity. After unplugging the air flow meter, the ECU uses an air flow replacement value for fuel injection, which can increase the speed. Due to the low actual intake volume, the acceleration is slow.

Diesel Generator Power Ratings: Standby vs Prime vs Continuous

Diesel generator sets are commonly used in a variety of sectors due to their dependable performance and high efficiency. They can be used for emergency power supply in the event of a power cut or used in places without connection to a power grid. When selecting a diesel generator for your home or business, you need to consider many factors, such as generator’s ratings. In this article, we’ll explain the three basic rating types - standby, prime, and continuous in diesel generators. ISO-8528-1:2018 defines basic generator set rating categories based on four operational categories: Emergency Standby Power (ESP), Prime Power (PRP), Continuous Power (COP) and Limited-Time Running Prime (LTP). Read on and learn the application of power ratings for engines used in generating sets. Standby Power Rating Standby Power(ESP) is used to supply emergency power when the external power supply is interrupted, such as power outages. Standby power rated generators can supply reliable electricity as t...

How to Choose a Household Mini Generator

With the improvement of people's living standards, there are more and more household appliances, such as rice cookers, microwaves, kettles, refrigerators, air - conditioners, washing machines, etc. It can be said that every household has them. But what if there is a power outage? These appliances won't work properly, and our lives will be greatly disrupted. How can we avoid this? We can use household mini - generators to provide convenience in power consumption. So, how to choose a good household mini - generator? Consider the noise level Since it is for household use, when choosing a household mini - generator, we need to check whether the noise will affect the neighbors. Generally, the seller will demonstrate the performance of the generator in advance. A good household generator can reduce noise by about 80%. Choose a generator with a moderate price Due to different brands, there are significant differences in power, and consequently, the price differences of househ...

How to Choose Efficient Diesel Generators for the Film and Television Industry?

In the film and television industry, the stability of the electricity supply during filming is crucial. Whether the equipment are the cameras or the lighting equipment on the filming site, or the post-production equipment, they all need stable and reliable power support. Unstable or interrupted power can result in interrupted filming, damage to equipment, and even affecting the progress and quality of the entire project. Therefore, investing in high-efficiency diesel generator sets has become an important measure for the film and television industry to ensure the reliable power supply for shooting. Determine the power requirements Before choosing a diesel generator set for the film and television industry, it’s necessary to figure out the total power needs, including the electricity demand of the shooting location, the total power of the electrical equipment and the time of using electricity. Also consider whether there are special needs for the generators such as low noise level and...
