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 ...

The internal combustion engine, now more than 200 years old, will be with us for a long time to come yet. Powering more than 1 billion vehicles on the planet and almost 100 million new ones each year, ...
