The upside of gasoline direct injection (GDI) engines is widely seen as being improved fuel economy coupled with an increase in specific power (especially with turbocharging), enabling significant downsizing. The extent of fuel-air mixing can be affected by injection system design. Credit: ACS, Zimmerman et al.

This has resulted in higher catalyst loading per volume of substrate and led to downsizing of systems from those available in 2010. A wide variety of technology options can be deployed on heavy-duty engines and vehicles to reduce engine-out NO x while improving fuel economy to reduce the total cost of ownership of trucks.

MARCH 4, 2009

Fiat expects that Multiair, with direct control of the air through the intake engine valves without using the throttle, can help reduce fuel consumption by up to 10% for turbocharged or naturally aspirated gasoline engines. Pollutant emissions are likewise reduced through combustion control.

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

Renault’s ongoing downsizing strategy is aimed at reducing the cubic capacity of its engines in order to bring down fuel consumption and CO 2 emissions, without detracting from performance. The downsizing process involved shortening the piston stroke by reducing the size of the crank pin and conrod assembly. Select Engines.

This means that in addition the power demand is more difficult to achieve with engine downsizing and transmission down-speeding alone. Thermal management of the electrical machine is another critical factor, because the duration of the boosting and energy recovery operating modes directly impacts fuel economy and emissions.
