An in-depth analysis of the inner workings of the HEUI injection system, which can be found on 6.0L and 7.3L Power Stroke diesel engines. Learn how the HEUI system uses pressurized engine oil to create injection pressures far greater than a typical mechanical injector pump setup.
Learn how the modern common rail injection system works, why its injection pressures are far greater, and its injection control far superior to alternative injection systems.
A look inside of a a Piezo injector and why it offers modern common rail injection systems the opportunity to realize multiple injection events per combustion cycle.
Can you supercharge your diesel? In fact, you can. Supercharger kits for common diesel engines play on supercharging's inherent advantage in an effort to suppress the primary downfall of turbocharging alone, lag.
How biodiesel is made and whether or not biodiesel is right for you. Learn about blending biodiesel with conventional petroleum based diesel fuel in addition to possible problems associated with biodiesel's lower energy content and lubricity characteristics.
For far too long the differences between horsepower and torque have been debated when in fact the relationship between the two of more importance. Learn about horsepower and torque, how they differ, and how they relate to your engine's performance characteristics.
Descriptions and properties of common diesel fuel types and grades, including off-road diesel, #2 diesel, #1 diesel, and winterized diesel fuel blends.
