Abstract
Internal combustion engines with lean homogeneous charge and
auto-ignition combustion of gasoline fuels have the capability to
significantly reduce fuel consumption and realize ultra-low
engine-out NOx emissions. Group research of Volkswagen
AG has therefore defined the Gasoline Compression Ignition
combustion (GCI®) concept. A detailed investigation of this novel
combustion process has been carried out on test bench engines and
test vehicles by group research of Volkswagen AG and IAV GmbH
Gifhorn.
Experimental results confirm the theoretically expected
potential for improved efficiency and emissions behavior.
Volkswagen AG and IAV GmbH will utilize a highly flexible
externally supercharged variable valve train (VVT) engine for
future investigations to extend the understanding of gas exchange
and EGR strategy as well as the boost demands of gasoline
auto-ignition combustion processes. One of the main topics is the
extension of the GCI® map area to both higher and lower brake mean
effective pressures to spread the advantage in fuel
consumption.
