New Mercedes-AMG SL 43 features engine with electric exhaust gas turbocharger derived directly from Formula 1

Green Car Congress

liter turbocharged M139 engine featuring an electric exhaust gas turbocharger. The electric exhaust gas turbocharger solves the conventional trade-off between a small, responsive turbocharger yielding a lower total output and a large turbocharger capable of high peak power with less responsiveness. An electric motor around 1.6

ORNL researchers quantify the effect of increasing highway speed on fuel economy

Green Car Congress

One tip is that drivers should obey the speed limit since the fuel economy of most vehicles decreases above 50 mph [80 km/h]. ORNL staff members John Thomas, Shean Huff and Brian West have worked to quantify this trend through analysis of dynamometer testing results for 74 vehicles at steady-state speeds from 50 to 80 mph [80 to 129 km/h].

Jaguar Introduces C-X75 Gas Micro-turbine Extended Range Electric Vehicle Concept

Green Car Congress

The plug-in, electric drive supercar has an all-electric range of 110 km (68 miles) plus a potential top speed of 330 km/h (205 mph), acceleration from 0-100 km/h (62 mph) in 3.4 seconds, and 80-145 km/h (50-90 mph) in 2.3 Active aerodynamics allow for a simple fuselage section that remains stable at very high speeds.

UK consortium developing biogas and hydrogen dual-fuel Class 66 locomotive

Green Car Congress

Maximum speed is 75 mph. Exhaust emissions will be assessed in line with the latest RSSB guidance to understand both the baseline conditions and the impact of dual-fuelling for both hydrogen and biogas. The Freightliner Class 66 locomotives are 3300hp diesel electric mainline units introduced in 1998.

Audi A3 launching with new 4-cylinder engines; cylinder-on-demand, supplementary indirect injection, start-stop and modular efficiency technologies

Green Car Congress

In the previous model, some of the gasoline engines were mounted with a forward tilt of 10 degrees, and their exhaust side faced the radiator grille, while the exhaust side of the TDI engine faced the bulkhead. The turbocharger was redesigned for the use of low-pressure exhaust gas recirculation. liters of fuel per 100 km (57.4

ORNL study quantifies fuel economy costs of common driver practices and vehicle alterations

Green Car Congress

The results for the SUV pulling a 3,500 pound enclosed cargo trailer were significant, resulting in FE penalties ranging from 30%, for the city cycle, to 50% at 80 mph (129 km/h), at which point significant CO generation indicated protective enrichment due to high load. l/100 km) at 60 mph (97 km/h) to 33 mpg (7.1 l/100km); and.

New Ford Mustang receives its own 2.3L EcoBoost variant

Green Car Congress

The cylinder head features an integrated exhaust manifold that separates the inner and outer pairs of cylinders into each inlet passage to the turbo. Keeping the exhaust pulses separated from the next cylinder in the firing order eliminates mixing losses and maximizes pulse energy to the turbine wheel. Larger exhaust valves.
