Understanding and maintaining wastegate devices on engines
The wastegate on turbochargers prevents it from overboosting air pressure at high engine rpm.
Dirty electrical signals
If the power delivered does not match the needs of the circuit, then it can malfunction, suffer premature failure, or have unexplained readings or response.
Diesel tune-up tips
A 9-point plan for peak diesel performance.
Cetane and diesel performance
It’s all about combustion, whether you are running a gas or diesel engine. With a gas engine, octane is key. The higher the octane content of gas, the more pressure or heat that fuel can resist before combusting. In diesel fuel, it’s all about cetane.
A diesel compresses intake air so much that it reaches a temperature of nearly 400°F., which is the ignition point of the fuel. Once the air is compressed, the fuel is injected and ignites. Unlike a gas engine that premixes fuel and air, the fuel and intake air mixture in diesels is not uniformly mixed.
Evaporating Concern
In the early 1970s, when the auto industry faced scrutiny and pressure to reduce air pollution, it was recognized that vehicles were polluting even when they were not running.
