Combustion engines still have much potential to save energy and reduce emissions. The present trend is to use smaller engines of the same or even increased power. Engines with a reduced cylinder capacity consume less fuel due to their smaller weight, smaller friction, and smaller amount of exhaust heat. This so-called downsizing, however, is associated […]
