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

Green Car Congress

Further, at low loads, the ESTEC engine improves fuel consumption by 11% in the JC08 mode. Improving the vehicle fuel economy is a must due to the climate change and energy issues. Additionally, the intake manifold, EGR cooler and EGR valve are directly connected to reduce the chance of condensation from the cooler.

BorgWarner suggests Valve-Event Modulated Boost system can offer 6-17% fuel economy benefit over already downsized and turbocharged engines

Green Car Congress

The VEMB system uses a concentric camshaft, blow-down manifold and scavenge manifold to separate the exhaust event into two phases: high-energy blow-down to the turbo without pumping losses, and high-hydrocarbon scavenge to the EGR system. to 2 ratio points and maintain the same knock limit for an additional 3-4% improvement in fuel economy.
