When to Replace a Diesel Fuel Injector: Heavy Equipment Edition

Whether you own a Caterpillar, Komatsu or Cummins, maintaining your diesel engine is crucial for the performance, efficiency and reliability of your equipment. When something starts to fail with your engine, it can be frustrating; you might be able to feel it, see it, or even smell it, but be unsure of the cause. Many of these issues may arise because diesel engines largely depend on their fuel injection systems delivering the right amount of fuel at the right time; the slightest problem with its components can lead to drastically diminished performance. Fortunately, as specialists in supplying quality replacement parts, Jaytrac have compiled a list of common signs that may indicate you need a fuel injector replacement or repair.

Loss of Power

If you’re stepping on the throttle and noticing a distinct loss of power and performance from your equipment, this could indicate something is wrong with your fuel injection system. This can be incredibly frustrating, especially if you’re on-site and want to be able to complete a job quickly and efficiently. A simple look at your fuel injectors could ultimately save you a lot of time, and money.  

Poor Fuel Efficiency

You might notice that your fuel consumption per hour on site is higher than usual. Naturally, you want to be having the best fuel economy as possible when it comes to heavy equipment; this not only helps keep costs down but contributes to better environmental sustainability. Decreased efficiency is a key indicator that there is an issue with your fuel injectors, and well worth investigating.

Engine Misfire

If you are discovering issues when attempting to start your engine, such as stalling, hesitating or it simply needing to be repeatedly turned on, this could indicate a problem with your fuel injector. Whilst the various causes could range from ECM mapping, to the need to be replaced, having a smooth engine is hugely important, and frequent misfires can disrupt the working day. So, looking into why this might be happening should be a priority.

Excessive Exhaust Smoke and Fuel Smell

Some of the more noticeable signs that may create cause for concern are an increase in exhaust smoke and more fuel smell than usual. These changes to your equipment’s function are perhaps more immediate than the others on this list and could point towards a faulty fuel injector. 

 

Whilst these issues can be caused by a different source, or be solved by simply cleaning your injectors, it is worth diagnosing that the problem isn’t more extensive. A fuel injector that isn’t replaced when it needs to be can ultimately cause damage to other parts of your heavy equipment. So, if you’re having any of these issues with your Cat, Cummins or Komatsu engine, don’t delay, as Jaytrac’s equipment experts can provide you with replacement fuel injector parts or help with repairs.
