Diesel System Performance Issues

Diesel engines have many benefits over gasoline. They maintain their value better and tend to run cleaner and more efficiently. However, there are some things you need to keep in mind when using a diesel system.

If you own a diesel-powered vehicle or machine, regular upkeep is required. A lot of problems can be avoided with a few simple preventative practices. See below to learn more, and always consult your owner’s manual before working on your machine.

Fuel Pump Malfunction

Fuel injection pumps wear out over time. It is not always clear when the problem with your system is the injection device, but if you notice poorer performance over time, you might want to replace the pump. However, not every problem is due to wear and tear. Dirt that passes through the filter can cause diesel fuel not to be injected properly. Other factors to consider are the liners, valves and piston rings. If they are worn out, you will notice smokier exhaust and poor compression, along with your engine skipping or struggling to start. If you think your injection pump is faulty, reach out to a professional to repair or replace the part.

Keep Air Out of the System

Air is always trying to get into your diesel system. If piping is not fit properly or a nozzle does not close, you risk air getting into the system. Also, it would be best if you never let your tank run out, as this pushes air into the injection system. Too much air keeps your pumps from working correctly, so make sure you bleed the system regularly. Always exercise caution and consult your owner’s manual before proceeding.

Diesel-fueled systems are valuable in transportation and heavy-duty applications. Make sure you follow the procedures recommended by the manufacturer to keep your engine healthy. When properly maintained, diesel systems can last for years. If you notice a severe problem, always reach out to a professional for assistance.
