New Audi S models to feature new downsized 4.0L V8 with cylinder deactivation, energy recuperation and start-stop

Green Car Congress

This is a downsized platform from the prior 5.2L It accelerates the S6 from 0 to 100 km/h (62 mph) in 4.8 It accelerates the S6 from 0 to 100 km/h (62 mph) in 4.8 Both models have an electronically governed top speed of 250 km/h (155 mph). Acceleration from zero to 100 km/h (62 mph) takes 4.2 Compared to the 5.2L

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 —Marcello Canova.

Rotrak testing prototype variable drive supercharger in vehicle on dyno

Green Car Congress

In a 2010 paper, Roger Stone, Engineering Director, Torotrak noted that conventional turbo- and supercharging technologies are more than capable of delivering the required peak power and torque levels from downsized engines but suffer from a number of. It gives the next generation of downsized powertrains ‘big-engine’ response.

Fiat introducing new 2-cylinder 0.9L Turbo TwinAir in 2014 MiTo mini

Green Car Congress

liter engine is 184 km/h (114 mph) and it accelerates from 0 to 100 km/h in 11.4 With its unique intake cam profile, the MultiAir second generation further optimises thermodynamic efficiency of the engine by modulating the amount of exhaust gas recirculated in the combustion chamber (internal EGR). Top speed for the MiTo with the 0.9-liter

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.

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

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. 20 mph (32 km/h).
