Abstract

The new 125 kW engine from Volkswagen in the Golf GT represents a milestone in the development of direct-injection spark-ignition engines. Its performance far surpasses that of conventional engines with the same capacity while at the same time offering substantially improved fuel economy. This result has been achieved by a combination of downsizing, direct fuel injection and double supercharging. While part 1 described the engine design, part 2 deals with the thermodynamics.
