A significant drawback to HCCI engines is the knocking caused by rapid increases in pressure. Such knocking limits the capacity for high-load operation. To solve this problem, thermal stratification ...
In the big scheme of things, gas-powered internal-combustion engines aren't all that efficient, as most of what they generate is waste heat. Toyota is believed to offer the most thermally efficient ...
Most internal combustion engines are incredibly inefficient at turning fuel burned into usable energy. The efficiency by which they do so is measured in terms of "thermal efficiency", and most ...
