There are a multitude of generator fuel additives on the market that can help to keep the fuel injectors clean, and thereby prevent or at least slow down the clogging or complete fuel blockage due to debris build-up. However, no amount of additive will help when the injector components become worn or damaged over time. At this point the injectors will need to be replaced.
What to look out for:-
Increased fuel consumption
Generator struggling when running on load
Most common reasons for replacing the injectors include:
This is often quickly detected due to the smell of fuel and reduced fuel economy.It may simply require the replacement of an old O-ring, but if fuel is leaking from a crack in the injector body then the entire injector or injectors will need to be replaced, as soon as possible before the engine fails completely
Water Contamination in Fuel
Water is not a good lubricator and can wear out the injectors if this issue is not quickly detected and rectified. Low grade fuel will damage the injectors. Consistent levels of water in diesel fuel will over time destroy the injectors. Always replace Oil filters regularly and never miss replacement. Always use registered quality diesel fuel suppliers
Decreased Engine Power and Efficiency
This could be an electrical fault interfering with the correct timing of the injector(s), a clogged injector or a faulty component within an injector. Whatever the cause, the associated cylinder won’t receive the correct amount of diesel, which in turn can lead to misfiring and a generator that is running inefficiently
Ideally, the injectors should be replaced as a complete set so that the spray volume and pattern are the same for each one. This is not a straightforward job, and we therefore recommend that this is carried out by a qualified generator engineer from your manufacturer or PowerContinuity Ltd.
