An engine ECU must provide real-time control in order to realize low fuel consumption. In recent years, new control functions have been added to handle capabilities such as mechanisms that automatically shut off the engine when the vehicle is stopped and regeneration systems that utilize mechanical energy during deceleration. Other efforts to improve fuel efficiency within the engine itself include use of continuously variable exhaust valve mechanisms and high-volume Exhaust Gas Recirculation (EGR) systems to reduce pumping loss.

As solutions to increasingly complex control requirements such as these, Renesas supplies MCUs that combine high-performance CPUs and low power consumption for engine ECU systems and an extensive lineup of analog and power devices.
