Hitachi's Engine Control components

CO2 reduction exhausted from vehicles for global warming prevention is a matter of great urgency. We(Hitachi research laboratory) are working on research and development of the engine control components (sensors and actuators) and engine control system to achieveCO2 reduction. And we are contributing to society.

We think that an engine power-train system is important system for vehicle and this systems evolves every day for corresponding to environmental regulation of CO2 and exhaust emissions. We(Hitachi research laboratory) are working on research and development of the sensors(air flow sensor), the actuators (injector,variable valve), the engine control unit and the more suitable engine control logic which corresponds to environmental regulation. For corresponding to various needs speedily, We are working on research and development of a engine simulation and analysis,too. Moreover, We are researching about Next generation combustion engine system(HCCI) which reduces CO2 and exhaust emissions more for future environmental regulation.
