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.

Checking a diesel engine's compression by performing a leakdown test is a more detailed method of diagnosing the powerplant's condition and determining the amount (percentage) of blow-by.

Diesel engines don’t have spark plugs; instead, they use the super-heated air created by their high compression ratios to ignite the diesel fuel as it’s injected into the cylinder.

Is your engine underperforming? Our expert shares how a diesel engine compression test could provide the diagnosis.
