Diesel Engine Maintenance & Repair
(Click to Enlarge)

Diesel engines are a type of compression-ignition engine known for their high-performance and robust machinery. Unlike gasoline engines that use spark plugs, diesel engines compress air and inject fuel directly into the compressed air at high pressure. The heat generated by the compressed air ignites the diesel fuel spontaneously, causing it to burn and drive the engine’s pistons. Although known for their inherent durability, diesel engines require proper maintenance and proactive repair to unleash their full potential.

Central Diesel, Inc. specializes in a comprehensive range of diesel engine repair and maintenance services. We also offer premium engine parts, including top-quality generators, fuel injection systems, filtration and exhaust systems, turbocharger assemblies, and electrical components.

Common Diesel Engine Problems

Identifying diesel engine problems early on can prevent major repairs. Some prevalent issues include:

  • Black exhaust: This may indicate an imbalance of air-to-fuel proportions, possibly linked to issues with the air filter, injector, turbocharger, or EGR valve.
  • Glow plug failure: If you face difficulties starting your vehicle in cold weather, worn-out glow plugs might be the culprit.
  • Hard starting: This issue could signal low engine compression, problems with the fuel delivery system, or a worn-out battery.
  • Unusual noises: While diesel engines are naturally louder than gasoline engines, unusual noises may indicate problems with fuel injectors or low engine oil levels.
  • Oil oxidation: Air entering the oil system can disrupt proper lubrication, a common occurrence if a vehicle remains unused for an extended period.
  • Lack of power: Reduced power output may result from various issues, such as clogged fuel filters, problems with throttle linkage or fuel injectors, or excessive lubrication.
  • Increased compression ratio: While high compression ratios contribute to powerful, smooth-running engines, they can also interfere with fuel injection performance and lead to more frequent engine knocking.
