With a simple diesel engine compression test, it is possible to spot compression problems before they get worse. Here’s information on these tests and how to decide if it is time to perform one.

What is compression ignition? Compression ignition basically is the term that is used for describing the manner in which diesel engines function.

A compression test is to determine how much pressure the engine makes, and a leakdown test measures its ability to hold pressure.

Diesel vs. Gas The major difference between the gasoline and diesel engine is that the former relies on spark ignition and the latter on compression ignition.

A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand ...

Not all braking systems on semis have to be loud to be effective. Exhaust brakes make a fraction of the noise that compression brakes do, here's how they work.
