PowerDriver simulations predict thermoelectric exhaust waste heat recovery output of 300W, -2.5% in fuel consumption; prototyping begins

Green Car Congress

The European Union-funded PowerDriver project—a two-year, €3-million (US$4-million) research project initiated in February 2012 to turn exhaust gas waste heat into electricity using thermoelectric generator (TGEN) technology—has completed simulation work on on a potential automotive application.

New VW Golf now available to order with natural gas drive

Green Car Congress

The engine of the quasi-monovalent drive system is powered primarily with CNG (Compressed Natural Gas), but can also run on gasoline. The Golf TGI is also equipped with a gasoline tank with a useful capacity of 9 liters (2.4 Driving in CNG mode produces around 25% fewer carbon emissions than with gasoline.

Enogia and IFPEN partner on waste heat recovery in stationary and transport applications

Green Car Congress

Start-up Enogia and IFP Energies nouvelles (IFPEN) are forming a strategic partnership for the joint development and marketing of a range of Rankine technologies to convert heat into electricity. The innovation is based on the use of highly efficient micro-turbines capable of producing 5 to 100 kW of electricity.

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.

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas.

Audi introduces new CNG A3 Sportback

Green Car Congress

Its turbocharger with variable turbine geometry makes optimal use of the exhaust gas energy for early and harmonious torque development. This is supplemented by the additional range offered by the reserve gasoline tank with a net usable volume of 9 liters (2.4 The A3 Sportback 30 g-tron 1.5 lb-ft) of torque between 1,400 and 4,000 rpm.
