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

Green Car Congress

Current mild-hybrid vehicle projects, in partnership with Ford and Hyundai/Kia, that utilize advanced 48V lead-carbon batteries, can reduce CO 2 emissions by 15-20%, according to the latest data from the Advanced Lead Acid Battery Consortium (ALABC), presented at the Advanced Automotive Battery Conference (25-28 January, Mainz).

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

Green Car Congress

Alcohol-based transportation fuels from a wide range of biomass feedstocks including agricultural, forestry, municipal and industrial waste and specially grown crops and trees can potentially offer a substantial substitute for oil derived fuel. More modest downsizing up to 5 liters could offer a practical solution. In this manner a 3.6

ADEPT project to apply gasoline engine HyBoost system to diesel; 48V architecture; full hybrid fuel economy at much lower cost

Green Car Congress

The Ricardo-led Advanced Diesel Electric Powertrain (ADEPT) project will apply 48V “intelligent electrification” concepts, mild hybridization and waste heat recovery in a Ford Focus diesel demonstrator. It is capable of operating in exhaust temperatures up to 850 °C, at speeds up to 60,000 rpm and delivering a peak power of 2 kW (@12V).

A key part of the overall efficiency gain is the downsized 11-liter Volvo engine, featuring advanced fuel injection, cooling, oil and turbo-charging systems, as well as new “wave” pistons and other improvements. This new design added “wave” bumps on the side of the piston bowl, which allows the fuel to burn more cleanly.). for the D13.

The successful application of the technologies would allow a global vehicle manufacturer to reduce its in-use carbon footprint of a typical vehicle by 50g/km—a 30% reduction on today’s baseline. The exhaust gas can reach temperatures greater than 900 °C, whereas the turbine upper functional limit is 850 °C. SpeedStart.

Optimizing a CNG-Fueled Spark Injection Engine for a Parallel Hybrid Powertrain

Green Car Congress

In recent years two methods, namely downsizing and downspeeding, were established on the market to reduce CO 2 emissions while maintaining the driving performance of engines with identical effective power but a larger displacement. bar) is achieved by applying high- or low-pressure exhaust-gas recirculation loops. < IMEP < 22.5

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

Green Car Congress

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. Ambient or low grade waste heat is used as an energy source with the cryogen providing both the working fluid and heat sink. Earlier post.)
