Direct injection systems, in which a high-pressure fuel pump pressurizes the fuel for injection directly into the cylinder by an injector, provide greater freedom in the injection timing and volume than multi-point injection (MPI) systems. This can be expected to provide improved fuel economy.

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