Bosch ECU Insights

Bosch Engine Control Unit. In this technical insight we illustrate you several types of Bosch engine control units. First of all, Bosch ECUs should be divided in two macro areas: petrol ECUs and diesel ECUs. Then, for each area we are going to clarify what each the single character stands for.

Volumetric Efficiency maps

Definition and theory of volumetric efficiency. Examples of volumetric efficiency maps. Second example is Chevrolet Corvette with Delco engine control unit. In this case the volumetric efficiency V.E. is in function of RPM and air pressure (kPa). Max values corresponding to high RPM and high air pressure. Third example is V.E. for new Subaru with…
