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 ...

Most pickup trucks sold today have internal combustion engines. Passenger vehicles are powered by two main types of engines: compression, aka diesel, and spark ignition, aka gasoline. Besides the type ...

Every engine has a specific compression ratio. The air-fuel mixture is compressed in the cylinder to create an ignition, the force of which depends on the compression ratio: the volume of the cylinder ...

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 ...

In a conventional piston engine, the compression ratio defines the relationship between the largest and smallest volume of a cylinder - when its piston is at bottom dead centre and top dead centre ...
