Abstract

Currently the driver for innovations concerning the powertrain itself is mainly the reduction of fuel consumption which is directly connected to meeting CO2 emissions limits. This results in diverse solutions depending on the vehicle market and the engine class. Next to measures concerning a robust combustion concept design for extreme downsized engines, alternative transmission concepts and several hybrid vehicle architectures variants are also discussed. Bosch proposes for powertrains incorporating a spark ignition gasoline engine to build a bridge between the three main domains: internal combustion engine, transmission and electrification.
