"Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

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 ...

A compression test reveals the condition of your engine's valves, its valve seats, and piston rings and whether these parts are wearing evenly. Healthy engines should have compression over 100 psi per ...

Mechanical know how in our case has come largely from two sources. There have been those kind enough to show the way, and there has been the hard way. A long and proud lineup of 500-dollar cars has ...

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 ...

ABSTRACT An experimental investigation has been carried out to compare the indicated performance and heat release characteristics of a DI diesel engine at compression ratios of 18.4:1 and 15.4:1. The ...

A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

“Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...
