Best Diesel Injection Articles on TruckTrend.com
Insights on addressing a diesel’s “biggest need,” for efficiency and performance.
With no spark involved in a diesel engine's combustion, air and fuel are the lone ingredients that make the process happen, and copious amounts of each are very essential if you want to have any chance of increasing an oil burner's performance.
For most diesel engines, increasing intake-air pressure and volume is best achieved by adding larger or multiple turbochargers or nitrous oxide.
However, despite the importance of additional air, ramping a diesel's fuel flow has long been the sure way to increase horsepower and uber-critical torque, and there are several different ways to turn things up. For early, mechanically fueled oil-burners, the simple adjustment of a mixture screw (bolt) is all that's required. But in the popular "common-rail" diesel space, injector-size and fuel-pump output matter most, as well as ECM calibration, which ultimately manages said fuel system components and ensures they function optimally at all times.
MotorTrend's truck authors have penned many reports on fueling, providing insights on the best diesel-injection parts and how to select and install them, as well as great theory information about the way injectors and pumps function. This piece spotlights 10 of our best diesel-injection articles to help new readers understand the diesel-fueling process, or simply allow veteran followers to wax nostalgic for a few minutes.
