Toyota introducing new series of gasoline engines with gain of at least 10% fuel efficiency; up to 38% maximum thermal efficiency

Green Car Congress

Toyota Motor Corporation has developed a new series of fuel-efficient gasoline engines that achieve improved thermal efficiency. Use of the Atkinson cycle provides an increased expansion ratio and reduces waste heat through a high compression ratio (13.5), resulting in superior thermal efficiency. Click to enlarge. Low friction.
