In the fuel test, the compression is raised until the engine begins to “knock”—ie, the fuel in the cylinder ceases to burn smoothly and instead detonates before it can be ignited by the ...

One of the easiest ways to test an engine's health is by checking its compression. Testing compression isn't something the average muscle car owner would do every year, but it is a useful tool to ...

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.

We take a close look at what engine compression means, what it does, and how to test it.

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

ENGINE-TEST results are presented for simulated altitude conditions using a displacerpiston combustion-chamber on a 5-in. by 7-in. single-cylinder compression-ignition engine operating at 2000 r.p.m.

One of the key variables for an internal combustion engine is its compression ratio. This is the ratio of the maximum volume within the cylinder (when the piston is at bottom dead center) and the ...

In Two Stroke Spark Ignition engines the thermal efficiency increases with increase in compression ratio. Also, with higher compression ratios the lean burning limit increases because of the reduction ...
