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. and reduce emissions significantly.

Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

SwRI develops D-EGR demonstrator highlighting fuel-efficient, cost-effective engine; 10% and above fuel economy improvements

Green Car Congress

D-EGR is an engine and control concept that combines fuel reforming to produce hydrogen with high levels of exhaust gas recirculation (EGR) to achieve very high levels of thermal efficiency. Engines Fuel Efficiency Vehicle Systems' In 2013, SwRI reported a 2.0-liter other actuators used to enable the control of D-EGR combustion.
