BorgWarner Exhaust Heat Recovery System for hybrids can improve fuel economy by up to 8.5%

Green Car Congress

Developed for hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs), BorgWarner’s innovative Exhaust Heat Recovery System (EHRS) can improve fuel economy by up to 8.5% The EHRS reduces mechanical losses by using the energy conserved within the exhaust gas.

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. An electrical Variable Valve Timing system (VVT-iE) is a key element for implementing the Atkinson cycle. 1 and water-cooled EGR.

SAE Publishes Revised J1711 Standard to Measure Exhaust Emissions and Fuel Economy of Hybrids and Plug-in Hybrids

Green Car Congress

Also, the list of standard test procedures addressed in SAE J1711 has been expanded to cover all five major test cycle procedures (UDDS, HFEDS, US06, SC03, and Cold FTP) now being used to evaluate vehicle fuel economy. Consumable fuels that are covered by J1711 are limited to petroleum-based liquid fuels (e.g.,
