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 ...

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 using ...

How does compression ratio affect efficiency? What determines an engine's efficiency? This video describes the direct correlation between compression ratio and thermal efficiency. The theoretical ...

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...

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 ...

Let’s clarify the numbers: the current Formula 1 regulations allow an internal combustion engine compression ratio of 16:1 measured at ambient temperature. All power units checked in Australia were ...

Formula 1's governing body the FIA says the series' power unit manufacturers have unanimously approved changes to how engine compression ratios are measured, with revisions coming as early as 1 June.

With every passing day the Mule provides opportunities beyond our original expectations. Since the 467ci engine belongs to HPP editor Tom DeMauro, it is at our beck and call. This affords HPP the ...

The new Corvette Grand Sport debuts an all new LS6 engine generation for Chevy. It gets a larger 95-mm throttle body and a tunnel ram intake as well as a very high 13:1 compression ratio. But perhaps ...

Most engines generate power from an internal combustion system. On the basic level, these engines work by compressing fuel and air into a tight space. Within the cylinders of an engine, pistons pump ...

NYK will install a variable compression ratio system (VCR system) on two large LNG-fueled coal carriers to be built at Oshima Shipbuilding. The vessels are scheduled to be delivered by the end of 2025 ...

The FIA have announced changes to Formula 1's power unit regulations, most notably surrounding compression ratio, which have caused controversy over the winter. When the 2026 power unit regulations ...
