Tips On Generator Set Fuel Efficiency

What are some tips on generator set fuel efficiency?

  1. Avoid running the Genset on light loads
  2. Remove carbon deposits regularly
  3. Prevent the Genset from overloading
  4. Keep up with scheduled maintenance services
  5. Choose your generator properly


A generator set in the Philippines is used as an external mount to supply electrical power for a variety of purposes. This engine-based machine is essential for construction sites because it can power heavy equipment without any problem. Aside from that, it has proved to be useful in food, fitness, technological, and various industries in the country. From a business standpoint, generators are a smart choice when it comes to cost-efficiency. But how about fuel consumption? Here are some tips on generator set fuel efficiency.


Avoid Running the Genset On Light Loads

Every generator set has an optimal load-to-fuel consumption setting. To achieve diesel generator set fuel efficiency, you need to run it at the higher end of the load setting that it was designed for.

That means that if you only need to use one piece of equipment, you need to plug in other appliances to maintain the load. Otherwise, you will encounter a phenomenon known as “wet stacking”. Unburned fuel will accumulate in the exhaust and lead to a build-up of carbon deposits. For this reason, you need to ensure that you’re running your generator set in the optimal load range often.

But if the situation demands a light load, it is recommended to run the generator set on an increased load afterward. This way, the temperature can help get rid of the carbon deposits. If you’re using your generator for light load often, it is recommended to have a strict maintenance regime to keep it in the best condition.


Remove Carbon Deposits Regularly

Remove Carbon Deposits Regularly

One of the effects of running a generator set at a low load setting is the build-up of carbon deposits. This occurs because the pistons and cylinders operate best in high-pressure settings. When you operate on a low load, it results in poor combustion. The fuel won’t be burned properly and you will end up with soot in your Genset.

If you don’t remove the carbon deposits from the valves, injectors, and other engine components, the fuel consumption will increase as you continue to use the Genset. Typically, you need to remove the build-up every four to six months. But if you notice that the engine is not running smoothly but is shaking, vibrating, jerking, or producing smoke, you need to have it checked immediately.

To minimize the buildup of carbon in your generator set, it is recommended to run it at higher loads.


Prevent The Genset from Overloading

Running the Genset at higher loads doesn’t mean that you can overload it. Otherwise, the fuel consumption will increase significantly. This is why you should limit the number of appliances plugged into your generator. Some models have circuit breakers that help protect the engine from overloading. But if you don’t have one, you should be alert for the symptoms to prevent more engine problems.

If your generator set is overheating, this is a sure sign that it is overloaded. You will hear loud noises from the engine or the fans will be working twice as hard to cool the generator. Aside from that, you might also notice a reduction in power output.

When this occurs, don’t attempt to touch the surface with your bare hands. If your generator has a circuit breaker, it will trigger the generator to shut down in an event of overloading.


Keep Up with Scheduled Maintenance Services

Keep Up with Scheduled Maintenance Services

One of the best ways to maintain fuel efficiency is to have your generator set checked by a professional technician for preventive maintenance services (PMS). They have the right tools and experience to perform diagnostic tests on your engine to ensure that it’s still running smoothly. For example, a load banking test can help determine if the generator can perform at its peak output rate.

Depending on your usage frequency and the environment the Genset is used in, the maintenance schedule might vary. Factors such as dust accumulation, moisture in the site, and extreme temperatures are considered when determining how often maintenance should be done. Routine PMS allows professionals to check if there is anything that is affecting the Genset’s fuel consumption.

If the Genset is used for standby purposes on hospitals, laboratories, and data canter, maintenance is also a must. This way, you can rely on electricity when you need it the most.

Choose Your Generator Properly

One of the best ways to improve fuel efficiency is to use the right Genset for your current requirements. This will ensure that you will only use it for optimal loads so you can prevent over and under loading that can affect fuel consumption. Fortunately, there are various types of generators available in the market.

Other than the model, you should also be careful when choosing the brand and supplier of your generator set. A reputable company can help you if you encounter any problems down the road. Other than that, you will have peace of mind about the durability and longevity of the Genset.


Key Takeaway

Every generator set is designed with an optimal load-to-fuel consumption setting. Proper load usage and routine maintenance can help you save on fuel costs while prolonging the life of your Genset.
