Overview

Among internal combustion engines, diesel engines boast excellent thermal efficiency and can burn fuel that is not highly refined. They use a compression ignition system in which intake air is pressurized and fuel is injected into it, causing it to self-ignite. Such systems are not prone to knocking even when supercharging is used, so most diesel engines are used in conjunction with superchargers.

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