4 Common Diesel Engine Problems

 

4 Common Diesel Engine ProblemsDiesel engines have been around since the end of the 19th century, but they were originally only used on large farm equipment and other slow moving machinery. This was because of their initial limitations to generate speed, but development of the engine into the 1930s found this type of engine was just as capable of being used in an automobile as a gas powered one. However, they do have their differences and require special maintenance and they can develop unique problems all their own. Here are a few common issues surrounding modern diesel engines that will likely require a trip to a specialized diesel mechanic.

Failing Glow Plugs

One of the biggest differences between diesel and gas engines is the use of glow plugs instead of spark plugs. Diesel engines use glow plugs to generate warm air which is compressed with diesel fuel to create the force that pumps the pistons. Glow plugs utilize heating elements like the ones in toaster ovens and if they go bad due to corrosion or some other issue it will become extremely difficult, if not impossible, to start your vehicle.

Incorrect Engine Lubricants

A second cause of hard starting that is more often apparent during the winter is the use of the incorrect engine oil in the motor. It is important to use the right oil for the right season in diesel motors. The summer months may call for a single-weight oil while it may be necessary to use a multi-weight oil in the winter to ensure proper engine function.

Faulty Lead Acid Batteries

Diesel engines have a high compression ratio that places a greater load on the starter motor, which draws amperage from the battery. This puts immense amounts of stress on the battery and makes them more likely to die during elongated engine cranking. If your diesel engine is having trouble starting within a few cranks, don't be surprised if you end up needing a jump start.

Loss of Engine Power

Engine power loss is often related to the fuel delivery system. One of the biggest issues that causes this is neglecting to drain the bowl connected to the main fuel filter. This filter prevents impurities from making their way into the engine by collecting them in this specialized bowl. If it is not drained it will result in hard starting, poor acceleration and a rough idle as sufficient amounts of fuel will not be able to make its way to the combustion chamber.
