Diesel Engine Repair

Diesel engine systems are designed to use their own compression to ignite fuel, with durability, reliability, and optimization in mind. Gasoline engines work by mixing the fuel with air, compressing it with pistons, and igniting it with a spark plug. In a diesel engine, the rate of compression is more than three times that of a regular gasoline engine system. A diesel engine system works by compressing air at a high ratio, which creates a lot of heat. This compression causes fuel to be directly injected into the cylinder, where the fuel vapor is ignited. Spark plugs are not used in the construction of diesel engines. Diesel systems use glow plugs to start and run more efficiently in colder temperatures instead. For fast starts, glow plugs have two heating elements that allow them to get very hot very quickly. Turbochargers quickly compress the air flowing into the engine, increasing the compression ignition and allowing for more air to flow into the chamber. If there is more air in the combustion chamber, then more fuel can be added to the combustion process. Turbochargers improve the efficiency of diesel engine systems, which leads to more miles per gallon of diesel fuel.​

Benefits

You should be aware of problems with your diesel engine and seek repairs immediately, as it plays a major role in your vehicle. If you are listening in on the engine, it can be hard to diagnose diesel engine problems because diesel engines make a considerable amount of noise during normal, everyday operation. However, there are a number of symptoms indicating your diesel engine needs maintenance. Signs of low fuel pressure, such as a diesel engine running at lower RPMs or a hard-to-start engine, may also be symptoms of an insufficient fuel supply or poor fuel quality. Can allowing our staff to troubleshoot your diesel engine help ensure that the proper repair procedures are followed to repair the engine? Different diesel engine manufacturers require different preventive maintenance procedures, so referring to your owner’s manual will help you plan and schedule routine maintenance services. To increase the life of your diesel engine system and promote overall vehicle maintenance, keep all diesel engine components—glow plugs, fuel injectors, and turbochargers—in proper working order.​

Excessive Noise Diagnostic
Approximate Time: Call for Estimate
Diesel engines typically produce a louder roar than gas engines. Loud noises are not always normal. Excessive and worrisome sounds from diesel engines can be a cause for concern. If the engine starts to make loud, unpleasant noises, it may be time to take it to a mechanic. These sounds are often indicative of a problem. However, because a diesel engine is made up of many components and small systems, finding the exact cause of a noise can be challenging. Many motorists rely on an excessive noise diagnosis to help find the issue affecting their respective diesel engines. Faulty rods, injectors, pistons, and valves can all cause excessive noise. If pressure in the engine is off or oil levels are low, this may result in loud noises. The cost of repair will depend on the component that needs to be fixed, but it is cheaper to fix it sooner rather than later.

Excessive Smoke Diagnostic
Approximate Time: Call for Estimate
There are many reasons a diesel engine may emit excessive smoke, from worn cylinders and piston rings to faulty injectors and valves. The color of smoke can help a motorist diagnose the problem, which is fortunate. The color of the smoke emitted by a diesel engine depends on the issue. If there is black smoke coming from an engine, it usually indicates that there are fuel combustion problems. Possible causes of this type of smoke include using low-quality fuel, a dirty air filter, or too much fuel. The blue smoke is usually an indication that there's something wrong with the car's oil. If there is oil in the combustion chamber, blue smoke can be created as it burns. A diesel engine usually emits blue smoke when first started up. When fuel is not being burned correctly, white smoke often occurs. Worn injectors, damaged valves, and sticking piston rings can all cause white smoke.​

Glow Plug Replacement
Approximate Time: Call for Estimate
Diesel engines start with the help of pencil-shaped objects called glow plugs. Spark plugs in gasoline engines serve the same purpose as diesel equivalent. Glow plugs use heat to get the engine going, unlike spark plugs. An especially important role is played by glow plugs in cold weather. Diesel engines often experience ignition troubles when temperatures are low, which is why this is the case. Diesel engines require the air to reach a certain temperature for fuel ignition to occur, but they tend to give off heat when they are cold. This problem is solved by glow plugs providing enough heat for the fuel to ignite. Glow plugs usually only require a small amount of time to warm up before they can perform. Glow plugs give off a small light or glow while they're gathering heat. This process is often referred to as "glowing" as a result. After the glow plugs finish warming, drivers should be able to successfully start their diesel vehicles.

Hard Start & Drivability Diagnostic
Approximate Time: Call for Estimate
Many components and small systems are found in diesel engines. If there are issues with the system or its components, the car may have difficulty starting and require a drivability diagnostic. There are several things worth checking if your diesel engine is hard to start. The temperature is the first thing. The combustion process in diesel engines only occurs with heat. They may need to warm up the glow plugs before they can properly start the engine, if it uses them. Oil is second. A diesel engine's internal components work best when lubricated. Engine oil can prevent harmful friction from occurring by lubricating the engine's moving parts and can remove dirt and other damaging debris from the engine. A turbocharger may be harmed by a dirty or low amount of lubrication, which can then lead to drivability and hard starting issues. Hard starting issues may also be caused by a bad battery, fuel supply, and fuel injectors.​

Turbocharger Repair
Approximate Time: Call for Estimate
The turbocharger is a forced induction system that is responsible for providing extra air to the combustion chamber of an engine. A vehicle's exhaust gas powers turbochargers. One of the components within the turbocharger system, the exhaust gas, spins the turbine wheel. The turbine wheel then spins a compressor wheel. The compressor wheel sucks in a large amount of dense, outside air while spinning and compresses it. Because the air is high in temperature, it needs to be cooled by an air cooler. The air in the cooler lowers in temperature and gains even greater density before it enters the engine. The engine burns fuel more efficiently once compressed air allows more fuel to be added into the cylinder. Many drivers install turbochargers not only because they are fuel efficient and produce less CO2, but also to help their vehicles reach higher speeds.​
