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.

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

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

We walk you through a compression test, a great way to determine the condition of your valves and piston rings.

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 ...

A diesel engine makes gobs of torque thanks to its high compression ratio. With heat engines, an increase in the pressure difference from a compressed to an uncompressed piston equals an increase ...

Mazda’s powertrain team has brewed up a fancy new engine that, like a diesel, uses compression to activate the combustion process. In a press release on the new tech, Mazda tells us just how ...
