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.

Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

Starting from a energy-based powertrain simulation model validated on experimental data from the PHEV, the researchers conducted a first- and second-law analysis to identify the potential for engine waste heat recovery, considering a variety of driving cycles and assuming the vehicle operating in charge-sustaining (HEV) mode.

Toyota begins trial operation of hybrid power generation system: SOFCs plus micro turbines

Green Car Congress

The hybrid power generation system combines the use of solid oxide fuel cells (SOFCs) and micro gas turbines. In addition, it has a cogeneration system (combined heat and power) that uses the waste heat produced in power generation. The waste fuel is burned in the micro gas turbines, and electricity is generated as it rotates.

New ORNL non-precious metal catalyst shows promise as low-cost component for low-temperature exhaust aftertreatment

Green Car Congress

Researchers at Oak Ridge National Laboratory (ORNL) have developed a ternary mixed oxide catalyst composed of copper oxide, cobalt oxide, and ceria (dubbed “CCC”) that outperforms synthesized and commercial platinum group metal (PGM) catalysts for CO oxidation in simulated exhaust streams while showing no signs of inhibition—i.e.,
