Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...

A.Here you can see locations of sharp-edged material left from factory machining operations. Material removal should be kept to a minimum, since we are dealing with low engine rpm for which enlarged ...

SAE International Journal of Engines, Vol. 10, No. 3 (June 2017), pp. 817-831 (15 pages) ABSTRACT Increasing compression ratio (CR) is one of the most fundamental ways to improve engine efficiency, ...

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 ...

WinGD claims the VCR technology can deliver up to 25% fuel savings and 33% lower methane slip, depending on fuel and engine load.

One of the main reasons diesel cars offer better mileage is the higher energy content of diesel fuel. Diesel contains more ...

At least 150hp of a Pro Stock engine is due to the use of ultra high compression ratios (CR) of 16:1--or more. 110 octane race fuels make this possible, but don't be fooled into thinking that the use ...

SAE International Journal of Engines, Vol. 11, No. 6 (2018), pp. 643-656 (14 pages) In this work, various techniques are numerically investigated to assess and quantify their relative effectiveness in ...

Nissan’s variable-compression turbo (VC-Turbo) is a unique engine capable of variable compression adjustment. Unlike traditional engines, which have a fixed compression ratio, the VC-Turbo engine ...

Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...
