In the golden age of American muscle cars, three engine manufacturers dominated both NASCAR and the strets of the U.S. Here's ...

Any diesel-engine manufacturer that confidently claims it produces an oil-burner with the “world’s lowest compression ratio,” will no doubt draw the immediate attention of inquisitive enthusiasts, ...

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 ...

SAE International Journal of Engines, Vol. 2, No. 1 (2009), pp. 1314-1326 (13 pages) ABSTRACT A new combustion system with a low compression ratio (CR), specifically oriented towards the exploitment ...

“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 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 ...
