Diesel engines are known for their long-lasting abilities over long journeys, whether for industrial or marine-based engines. But even a diesel engine may sometimes experience a power issue. You may find your diesel engine losing power when it’s hot or when it’s under load, for example. If your diesel engine experiences a sudden loss of power, there are several different things that could be causing the problem.

1. Clogged Fuel Filter

The fuel filter removes impurities from the gas so that they don’t find their way into the engine. If the fuel filter is clogged, then it won’t be able to properly filter out contaminants, which will cause the engine to eventually lose power.

2. Clogged Exhaust Pipe

The exhaust system, made up of the catalytic converter and the muffler, cuts down on the amount of pollution produced from exhaust fumes. If the pipe was to get clogged, this would weaken the power of the engine.

3. Dirty Air Filter

Engines use a mix of gasoline and air to generate power. Air taken in from the outside goes through a filter to keep out dirt, debris, bugs and other contaminants. If the air filter has not been cleaned or replaced in a while, it will prevent the engine from generating enough power.

Solutions for a Diesel Engine Losing Power

If your diesel engine is experiencing power loss, there are a few solutions you can try:

1. Change the oil: Oil can become gunky if not regularly maintained, which will make it more challenging to move through your engine. This can lead to clogs and overall problems with your system. Moreover, your engine will require more power to move the thickened oil through. Changing your oil regularly is one of the easiest ways to stay on top of power issues.

2. Use high-quality fuel: Lower-grade fuel has more risk of contamination, so it can be worthwhile to invest in the best fuel possible.

3. Clean and/or change your filters: Since the fuel and air filters can have a big impact on how your engine runs, make sure to check and service them regularly to prevent buildups and clogs. This is also a case where using a high-quality filter is worth the investment.

4. Get it checked out: If you’re not sure what the issue may be, don’t hesitate to get it checked out. Getting help from a professional can save you the time and expense of dealing with a bigger problem down the line.
