OVERVIEW

Recently, the need to reduce CO2 levels has made increased fuel economy an urgent matter in Japan and Europe. Use of the highly efficient diesel engine is expected to increase and measures against emissions such as soot are a major problem. Gasoline engines, on the other hand, are more sustainable in terms of exhaust emissions, and are steadily approaching the diesel engine in terms of fuel economy as well. Since introducing a direct fuel injection engine control system in 1997, the Hitachi Group has continued to develop and manufacture system control and the main components for it, and now we are expanding into Europe as well. We are also proposing various advanced system solutions in response to needs for automobile fuel economy, emissions and power.
