Diesel Repair
Built with durability, reliability, and optimization in mind, diesel engine systems are designed to use their own compression to ignite fuel. In gasoline engines, the fuel is mixed with air, compressed by pistons, and ignited by a spark plug.
The rate of compression in a diesel engine is more than three times that of a regular gasoline engine system. In a diesel engine system, the air is compressed at a high compression ratio, which introduces a great amount of heat. Following this compression, fuel is directly injected into the cylinder, where the fuel vapor is ignited.
Glow plugs have two heating elements that allow them to get very hot very quickly for fast starts. Turbochargers increase the compression ignition by quickly compressing the air flowing into the engine, allowing for more air to flow into the chamber. More air in the combustion chamber means more fuel can be added to the combustion process. Turbochargers provide diesel engine systems with improved efficiency, and ultimately, more miles per gallon of diesel fuel.
Your diesel engine plays a major role in your vehicle, so it is especially important that you be aware of problems and seek repairs immediately. Because diesel engines make a considerable amount of noise during normal, everyday operation, diagnosing diesel engine problems can be hard to do if you are listening in on the engine.
However, there are a number of symptoms you can watch out for that indicate your diesel engine needs maintenance. A diesel engine running at lower RPMs or a hard-to-start engine are signs of low fuel pressure, but these signs may also be symptoms of an insufficient fuel supply or poor fuel quality. Allowing our team to troubleshoot your diesel engine can help ensure that the proper repair procedures are followed to repair the engine. Every diesel engine manufacturer requires different preventive maintenance procedures, so referring to your owner’s manual will help in planning and scheduling routine maintenance services.
Keeping all diesel engine components—glow plugs, fuel injectors, and turbochargers—in proper working order will increase the life of your diesel engine system while promoting overall vehicle maintenance.
