“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 ...

By C.J. Baker The true compression ratio of an engine is a critical factor with today's low-octane gasolines Shown here are the component volumes that comprise ...

Strictly defined, compression ratio is the total volume above the piston at bottom dead center (BDC), divided by the total volume above the piston at top dead center (TDC). First, let's look at the ...

You might talk about it often, but do you really know what compression is all about? Every engine has to make it and those that don't are hurtin' for sure. But, here's the confusing part, for this ...

Compression in a diesel engine is essential for effective and efficient performance. And when compression is lacking, damage can result. That is why it’s imperative to know whether your engine’s ...

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 ...
