Apart from the very curious, not many people ask why diesel engines, compared to gasoline, run higher compression ratios. The argument is reasonably straightforward and starts with fuel ...

You’re not going to notice much difference here. It’s still a traditional four-stroke, internal combustion engine, after all. Just when you think we’re approaching a point where we can’t improve on a ...

The compression ratio isn’t just a number: it’s one of the greatest determining factors in engine building. Compression ratio determines the type of fuel, how much boost, and has a significant ...

"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 ...

At first glance, the concept of engine compression is simple enough:It's the ratio of the volume of the combustion chamber and bore when thepiston is at bottom dead center (BDC) versus when it is at ...

The temperature of the refrigerant entering the compressor’s cylinder also has an effect on capacity, but for this article, we’ll focus on pressures. COMPRESSION RATIOS Both the high- and low-side ...

Installing a recycle valve in parallel with the antisurge valve of a turbine-driven multistage (low pressure/high pressure) centrifugal compressor, in combination with control system modifications, ...
