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.

As a result, as the ethanol content of the fuel is increased, the fuel economy and driving range for a given fuel tank size are reduced. Downsizing/downspeeding. Thus, the benefit of increased CR enabled by increasing ethanol content is engine design specific. Volumetric fuel economy.

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. Its simple design and low levels of friction make it particularly competitive in terms of the performance it delivers for its price.

Small displacement engines offer excellent CO 2 and fuel economy benefits; they have lower parasitic losses and operate more efficiently under part load conditions. They have also designed a 100 mpg UK (83 mpg US, 2.8 It comprises materials experts and vehicle designers as well as body and powertrain engineers.
