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.

ARPA-E awards U-M $1.9M to develop advanced low-cost high-efficiency engine; boosting, highly dilute combustion and 48V system

Green Car Congress

million to a project to develop a high-efficiency engine system that integrates a compact micro-hybrid configuration of a supercharger with an electric waste heat recovery system and employs high rates of recirculated exhaust gases. An engine’s response depends on its ability to take in fresh air and convert it to power.

Dearman begins on-vehicle testing of Gen 2 transport refrigeration system powered by liquid air engine; lighter, more efficient

Green Car Congress

The system is powered by an innovative, liquid nitrogen Dearman engine, which replaces the standard diesel engine. The Dearman liquid air engine is an innovative heat engine that uses liquid air (or liquid nitrogen) as a “fuel” and emits cold air as exhaust. Earlier post.) Earlier post.)

ALABC: 48V mild hybrids can meet emission targets with CO2 reductions of 15-20%

Green Car Congress

The T-Hybrid (based on a Kia Optima) ( earlier post ) and the ADEPT (based on a Ford Focus) ( earlier post ) both utilize an advanced 48V lead-carbon battery system with bolt-on electrical components that allow for significant engine-downsizing without loss in performance. This concept vehicle is powered by the Optima’s existing 1.7

CPT launching water-cooled electric supercharger for commercial diesel engines

Green Car Congress

At the 17 th Supercharging conference this week in Dresden, Controlled Power Technologies (CPT) will launch what it says is the first water-cooled electric supercharger developed for “quasi-continuous” boosting of commercial diesel engines, including those developed for off highway applications. tonnes gross vehicle weight.

Study finds highly-turbocharged alcohol-fueled DISI engines could be more efficient than diesels

Green Car Congress

Highly turbocharged alcohol-fueled direct-injection spark-ignition (DISI) engines operated at a high compression ratio could be as or more efficient than diesel engines while also providing advantages of lower vehicle cost, lower emissions and higher power, according to a recent modeling study by Leslie Bromberg and Daniel Cohn at MIT.
