Aboard Engineering has been supporting the MCE-5 company for developing its engine management system, along the innovative project of Variable Control Ratio engine. The VCRi project aims to demonstrative the gain due to the VCR system for power, consumption and CO2 emission level downsized supercharged engine.
System Architecture

The engine is a 1.5l 4-cylinders twin VVT (Variable Valve Timing) and supercharged (twin turbo). The fuel system is either gasoline direct injection or port fuel injection. Two ECUs control the engine functions via the CAN bus communication.



Aboard Engineering has defined the system architecture, developed, integrated the control strategies and ensured the system tuning on engine dyno and on demonstration vehicles.
