Medium/Heavy Duty Engine Control Unit


The Engine Control Unit (ECU) was designed as a flexible, cost effective solution for controlling diesel engine and vehicle functions in commercial vehicle applications to meet the Euro IV and Euro V emission levels. This is done by monitoring the relevant sensor signals and driving the appropriate electrical actuators as well as the internal combustion process.
