Gasoline direct
injection technology helps the Ecotec
engine produce more power while maintaining the lower
fuel consumption of a small displacement
port - injected
engine.
With this new combustion chamber shape and the precise control of direct
injection, the compression ratio has been increased to 11.1:1 (up from 10.5:1 on the previous
port - injected
engine), yet the
engine still operates on regular unleaded
fuel.
Injection is split between the direct and
port injectors according to the
engine load to help
fuel economy.
The cooling effect of the directly injected
fuel also results in a higher compression ratio than on
port injection engines, bringing further efficiency improvements.
The new
engine displaces just 4.2 liters, and uses efficient direct -
