Introduction
The special concept behind this engine is, above all,
the combination of direct petrol injection, dual-
charging and downsizing.
-Volkswagen ud direct petrol injection for the first time in the Lupo FSI model year 2001.
-
In dual-charging, the engine is charged by a
mechanical compressor and/or a turbocharger.
-Downsizing is replacing a large-capacity engine with a powerplant with smaller displacement and/
or fewer cylinders. This reduces the internal friction
and this the fuel consumption without the power or
torque being reduced.
