This report studies model-based embedded system design for the control of Internal Combustion (IC) engines. The advantages of model-based design and the development tools are discussed. The application of this method for IC engine control is the focus of the first part of the report. In the second part, the Hardware-In-the-Loop (HIL) simulation is introduced with emphasis on the engine controller and its modification for lean operation control. For the IC engine control, the control functionalities of an engine electronic control unit (ECU) in dSPACE Automotive Simulation Models (ASM) are analyzed. The lean combustion control model is implemented in a hardware engine ECU - MotoTron Engine Control Module (ECM) and validated by a HIL simulator. The HIL simulator used for the simulation study is dSPACE E-Drive HIL simulator. The HIL simulation result shows that the developed lean combustion control strategy can reduce fuel consumption. The lean operation at a lambda value of 1.2 is seen to have the lowest injection duration while still producing the same amount of torque. It is also found that the implemented method is able to meet the required torque better at the lower load operating conditions. The variation in the output torque is increased at the higher load conditions.
