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

Green Car Congress

Internal combustion engines have been significantly improving in the past decade, after the adoption of technologies such as Gasoline Direct Injection, mild electrification, downsizing and turbocharging. The OSU EcoCAR prototype vehicle features an extended-range electric architecture with a downsized 1.8L

Downsized 4.0 TFSI for Audi S8 cuts fuel consumption 23% compared to predecessor; cylinder deactivation and start-stop

Green Car Congress

Audi’s principle of downsizing: “ Forced induction replaces displacement ” One twin-scroll turbocharger per cylinder bank compresses the fresh air. From each pair of cylinders, the exhaust ports lead separately to a manifold and the turbocharger housing; they are not combined until immediately ahead of the turbine.

2014 Sprinter van for US standard with new 2.1L diesel; new driver assistance features

Green Car Congress

Since 2010, all Sprinters in the US have been powered by BlueTEC diesel engines, marking the first use of BlueTEC technology, with its selective catalytic reduction (SCR) exhaust aftertreatment system, in the commercial van market here. The two overhead camshafts actuate 16 intake and exhaust valves.

New Volkswagen Polo BlueGT with cylinder deactivation offers gasoline engine fuel economy of up to 52 mpg US

Green Car Congress

With a top speed of 210 km/h (130 mph), the car accelerates to 100 km/h in 7.9 This combination of efficiency and dynamic performance is enabled by the systematic interplay of ACT, downsizing (reduced engine displacement plus direct injection and charging) and BlueMotion Technology (Stop/Start system, battery regeneration).

Downsized 5.5L V8 Biturbo in S 63 AMG Delivers 25% Fuel Savings Compared to Predecessor; Stop-Start is Standard

Green Car Congress

For the first time, AMG is also utilizing the advantages of gasoline direct injection with spray-guided combustion and piezo-electric injectors: thanks to its higher thermodynamic efficiency, this technology makes more efficient use of fuel and leads to lower exhaust emissions. The 100 km/h mark is reached in 4.4

CPT VTES Electric Supercharger Selected for Two Projects

Green Car Congress

When applied to a radically downsized 1.2-liter liter turbocharged engine, VTES delivers in excess of a 50% increase in torque at engine speeds below 3,000rpm, more than compensating for insufficient power from the exhaust turbine. More than 90% of the available torque is delivered in less than a second. Compared with a 1.6-liter
