Several Tips For Reducing Fuel Consumption Of Diesel Generators

Aug. 08, 2022

Diesel generators are more popular due to their high energy efficiency and longer engine life, these diesel generators are mainly used in the commercial and large industrial sectors to obtain continuous power supply in the event of main grid failure. Rising diesel prices are increasing the overall operating costs of generators. Many users have been paying attention to the fuel consumption rate of diesel generator sets. So how to run diesel generators more efficiently, get high power output with low fuel consumption, and how to improve the fuel efficiency of diesel generators is the most important thing to understand.


How to reduce the fuel consumption of the generator?

During operation, the engine burns to generate high temperatures. This high temperature is a major cause of carbon deposits in valves, pistons and other components. Failure to clean all of these components in a timely manner reduces performance and increases diesel consumption rates. All in all, we can say that proper maintenance and cleaning of parts within a fixed time period is just as important for getting a more efficient backup power service. Get a list of the most common and beneficial tips here to reduce generator fuel consumption rates.


1. Maintenance of diesel generator sets.

Regular maintenance and parts inspection of diesel generators can extend the life of the generator set. Also, if all the components and the engine are working properly, you can reduce the fuel consumption of the generator. Because proper maintenance can significantly reduce fuel costs. Therefore, it is very important to hire professional and expert technicians for generator set maintenance. In addition, they provide you with complete information on the part. If there are any faulty parts, they will be replaced with new and genuine parts.


2. Remove carbon at regular intervals.

We know that industrial diesel generators work by burning, so the related parts will generate high temperature. Due to the high temperatures, carbon polymers appear in valves, pistons and other generator set components. If these carbon deposits are not removed in time, it can affect the performance of the engine and significantly affect the fuel consumption rate. So if you use the engine kit continuously, have a professional remove the polymer carbon from the engine kit for you after 4-6 months.


3. Do not overload the diesel generator.

If the diesel engine is overloaded, it will increase fuel consumption and you will see black smoke from the engine. In addition, constant overload in the engine can damage parts and shorten service life. Therefore, be sure to check the generator's maximum load capacity and operate according to the manufacturer's recommendations.

4. Do not operate the generator under load.

It may sound the opposite, but you need to avoid underload operation of the genset. If you use an engine with less than 50% load capacity, your backup generator is at risk. Because when you run the generator under load, it will increase fuel consumption due to its maximum temperature operating characteristics.


5. Minimize operating frequency.

Always use or operate your generator during the required period. If backup power is not required, turn it off. As we all know, the power of diesel generators is much higher than that of the main generator, so use them as needed.


6. Buy from a trusted dealer.

Buying a generator from a trusted dealer is 100% authentic. Therefore, we recommend always choosing a dealer that has undergone a thorough inspection. Because generators are more expensive products, you won't buy them very often. In addition, you can get a full warranty on all ranges of industrial and domestic generators that come with a warranty on components including the genset engine. And a high-quality diesel engine also consumes very little fuel.


7. Maintain coolant temperature.

As we explained earlier, generator parts and engines face overheating problems due to combustion in diesel engines. You will face unplanned downtime due to overheating of the generator. Therefore, maintaining the cooling function (liquid cooling or water cooling) helps to improve the efficiency of the generator. Additionally, this will help reduce overall generator operating costs as well as low fuel consumption.


8. Choose well-known brand diesel generators.

China's brand of diesel generators, some of them are very famous, such as Yuchai diesel generators of Jiangsu Starlight Power series, Shangchai diesel generators, Cummins diesel generators, Volvo diesel generators, etc. The decision is yours, but it is important to check all the features, specifications and warranty details of the product before choosing any particular brand.


Overall, maintenance and proper maintenance of diesel generators can always help you get more efficient power output during operation. In addition, it features low fuel consumption, which reduces the running cost of the generator. However, without a proper understanding of industrial generator set maintenance techniques, it is difficult to get the correct output and your generator performance is getting weaker day by day. Bad and faulty components can increase the fuel consumption rate of a generator.
