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.

Citroën introduces first members of new 3-cylinder gasoline engine family; 1.0L and 1.2L PureTech reduce fuel consumption about 25%

Green Car Congress

To achieve these results, PureTech development called for a number of changes, chief among which were: Downsizing. The exhaust manifold is integrated directly in the cylinder head, which reduces the number of parts and overall weight. Top speed is up 7 mph (11 km/h), and fuel economy is also improved by up to 1.5 l/100km (52.3

Calls for an international 48V electrical standard for vehicles; looming WLTP implementation

Green Car Congress

This means that in addition the power demand is more difficult to achieve with engine downsizing and transmission down-speeding alone. mph] and potentially to provide torque assist at other road speeds including during engine-off coasting. The WLTP is significantly more dynamic with faster acceleration rates. Click to enlarge.

Lexus NX compact utility arrives in North America

Green Car Congress

liter turbocharged gasoline engine has a combination water-cooled cylinder head, integrated exhaust manifold and twin-scroll turbocharger. To minimize turbo lag, the four-into-two exhaust manifold system pairs cylinders according to their expansion or compression stroke to reduce pumping losses and eliminate exhaust gas interference.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

The alternative-fuel car evolved to reduce exhaust emissions and other problems derived from burning fossil fuels. The combination of harvesting whole forests and burning long-sequestered carbon sources such as coal or oil has impaired the Earth’s carbon cycle at an increasing pace. by Professor Andrew Alfonso Frank.
