Turbocharging of Downsized Gasoline DI Engines with 2 and 3 Cylinders 2011-24-0138
Turbocharged DISI engines with four cylinders have established
in the market and provide a performance comparable to larger
six-cylinder engines in the smaller compartment of a four-cylinder
engine. In the Japanese market, also turbo gasoline engines with
500 - 660 cm₃ displacement have a long tradition in Kei-Cars.
However, those engines show a lower specific performance as would
be required for propelling typical small or compact vehicles in
Europe. Recently, two-cylinder turbo engines have come to market,
which are found attractive with respect to sound, package, and also
enable low vehicle fuel consumption in NEDC test.
The paper presents a turbocharger layout study on 2- and
3-cylinder engines. It discusses the influence of cylinder
displacement volume on the sizing of turbines and compressors, and
how specific flow phenomena in the turbine can be captured in the
simulation model.
