Put in simple terms, the purpose of a fuel injector system is to allow for the right amount of fuel to be provided to the engine – and at the right time. Although the fundamentals of fuel injection are the same, when used in different applications, like marine, identifying faults and maintaining the health and integrity of the engine is different to say, a car or plant machinery. Like other industries, diesel fuel injectors used within the marine industry use either common rail or jerk systems – but that’s often where the similarities will end.

Marine Industry | United

Diesel fuel injector failure in marine applications

Diesel engines within the marine industry have a hefty task. Ships and boats are large and heavy, so engines that can pack a punch are a must, whether the ship is for commercial purposes or used for trade and shipping. Similar to other applications, it’s important to keep marine engines clean with regular maintenance although its differing environment can bring up a range of different problems. Like any other fuel injector, vapours from the fuel can collect and create a clog caused by build-up. Regular maintenance can identify issues like this and through professional DPF filter cleaning, eradicate the chances of a clog.

Small particles of dirt can easily find their way into the fuel system, but the biggest issue is water. If water gets into the fuel injector it can stop the engine or, if micro-organisms from the water get into the system and multiply; this can cause a huge blockage. It can be difficult to stop some water from getting into the tank but there are things you can do to reduce the damage.

Common signs of issues in marine machinery:

  • Loss of engine performance
  • Unburned fuel being found in the exhaust
  • Loss of power
  • Reduction in speed/difficulty getting up to speed
  • Clunky engine running
  • Black smoke

Reduce faults in marine diesel injector

The easiest way to reduce faults with your marine fuel injector is to complete regular monitoring of the injectors. At the first sign of any of the above common signs displaying, you’ll be able to put a plan into action sooner and reduce the changes of any further damage occurring. Regular cleaning is also advised – and is something we can complete at our on-site workshop. We supply reconditioned fuel injectors or repair the unit. The equipment we use is specially designed to expertly and thoroughly remove debris, gunk and build-up from the fuel injectors, returning it to a like-new state!
