If you check the numbers in the chart (Fig. 3) you will see that ... then it's borderline for a high-performance engine and compression readings will be artificially low. If the leakage is 15 ...

Nissan brought the first, and only, variable-compression engine to market. But its future doesn't look bright.

Adding an Accufab throttle body allowed our engine to top the 400 ... Note that the change in compression (see Kenne Bell Effect of Compression graph) reduced the power output across the board ...

The engine compression is the engine's combustion capacity necessary to make the motor run. A compression drop inside one or more cylinders will cause abnormal idling, power loss, higher fuel ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 ...

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now ...
