Toyota implements Atkinson cycle in non-hybrid ESTEC engine; up to 38% thermal efficiency and improved fuel economy

Green Car Congress

Engineers at Toyota have developed an approach to applying the Atkinson cycle—used in the engines in Toyota hybrids since 1997—for engines in conventional, non-hybrid vehicles. The Atkinson cycle with a high compression ratio is a common approach that hybrid vehicle engines use to enhance thermal efficiency.
