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 ...

How do you calculate a compression ratio, and what’s the ideal number for your build? Let’s find out.

Potential and limitations of a reduced compression ratio from 18:1 to 14:1 are underlined. Moreover, this paper aims to define initially the head guidelines for future combustion system designs in ...

High compression however extends the range of injection timings where useful work output can be generated. The coefficient of variation of work output increases with increasing engine speed and ...

The modern fighter jet is defined by its engine, which accelerates a tremendous volume of air rearward that it can propel an aircraft weighing as much as 70,000 pounds at supersonic speeds. While ...

Allowing for a continuously variable compression ratio and impressive power and efficiency thanks to the addition of a turbocharger, it’s previously only been seen as a 2.0-liter four-cylinder ...
