Todays diesel engine burns cleanly and run as quiet as many gasoline-powered engines.
Today’s Diesel Engines still maintain the torque, power, and reliability diesel engines are known for.
We will try to cover a wide range of information in our Diesel Engine Topics.

Here are some of the most common problems:
Diesel trucks that sit in place for too long between uses tend to have issues with oil oxidation. This means air can get into the oil, which causes bubbles that can prevent proper lubrication. The oil still needs to be changed as soon as possible to avoid potential engine damage.
Diesel engines always produce more smoke and exhaust than other vehicles. However, there are reasonable limits to what you should experience with the amount of exhaust and the black smoke. Black smoke will likely result in you receiving a clean air fine. The problem usually lies with the injector, injector pump, air filter or the turbocharger.
Some diesel engines can be occasionally hard to start up. This typically indicates low compression or problems with fuel delivery. It’s normal for a diesel engine to smoke when started, but it should not be difficult to start.
Diesel is significantly more viscous than other forms of gasoline, which means it is also much more easily contaminated. Some of the most common contaminants include soot, dilution, water and glycol. Any of these contaminants could cause major engine damage if they penetrate the fuel system.
Diesel engines are noisier than other types of engines. But, A significant amount of noise (more than you typically experience) likely indicates some sort of problem in your engine. An inconsistent knocking sound in the engine, is probably an issue with your fuel injectors. You will probably experience reduced performance until you have the issue repaired.
Higher Compression Ratio
Most diesel engines have a compression ratio of 20:1, compared to the standard 8:1 ratio in a gas powered engine. This higher ratio makes the engine more powerful, but can also cause some unique problems. A higher compression ratio can result in more engine knocking, causing some potential fuel injection problems.
Glow Plug Problems
Diesel engines don’t have spark plugs—they instead rely on glow plugs to ignite the fuel-air mixture. If you have a problem with a glow plug, it will make it almost impossible to start the engine.
