A diesel engine is powered by extreme air pressure that ignites the fuel in the cylinders to create internal combustion. This is why diesel vehicles require drivers to wait several seconds after attempting to start the ignition. The waiting period gives the air pressure time to accumulate in the cyl


Diesel engine servicing includes an oil change, inspection of the glow plugs, examination of the gaskets and attachment bolts and cleaning or replacement of the fuel and air filters. Regular maintenance is essential for vehicle safety, engine longevity and fuel efficiency. CarsDirect also recommends


The best diesel oil for an engine depends on the type of vehicle and how often the oil is changed. However, most diesel engine oils should be heavy-duty, fully synthetic products designed with high performance in mind.


Some ways to improve the performance of a diesel engine include adding a high flow exhaust system, changing or upgrading the computer chips in the Electronic Control Module, upgrading fuel injectors, upgrading air intake systems and changing differential gear ratio. Each of these changes alone impro


Diesel engines require a high viscosity oil that is able to withstand a significant amount of force. Most diesel engines suggest using 15W-40, as a result of having a heavier and thicker consistency. Diesel engines undergo combustion at a higher compression ratio, which requires a better performing


According to United Diesel, causes of a non-starting diesel engine include low compression, insufficient fuel pressure, faulty glow plugs, contaminated fuel and low crank speed. Others include insufficient fuel, clogged fuel filters and internal engine problems. Many of these issues require professi


Before trying to start a cold diesel engine, make sure that the battery is completely charged, and turn off all devices that use a lot of power, including the radio, air conditioner and heater. Obtain glow plugs or block heaters, and use them when starting the engine in cold weather to ensure that t


If properly maintained, a diesel engine can last between 300,000 to 600,000 miles. In a few cases, drivers have reported that their diesel engines endured up to 1,000,000 miles.


When used under operating conditions that are identical to that of a gasoline engine, a diesel engine should last at least twice as long as its counterpart. Diesel engines operate at lower speeds than gasoline engines, which means their internal parts don't rub together and wear out as often.


Basic maintenance tips for diesel engines include changing fluids routinely, replacing oil filters often, checking the glow plugs frequently and inspecting the gaskets regularly. Monitoring fluid levels regularly and allowing the engine to cool before replacing or checking fluids are other basic mai
