Integrated Powertrain Control: Optimal Engine Operating Points.
Within the automotive powertrain industry, the engine operating point is an important part of the vehicle’s performance and emissions. The engine operating point determined by the engine speed and torque, impacts fuel consumption, available propulsion power, and emissions. The Brake Specific Fuel Consumption (BSFC) is commonly used as an effective measure of engine performance.
This whitepaper discusses a method of determining an optimal set of operating points for an internal combustion engine based on the BSFC. The described approach is general and may be extended to include additional engine information such as NOx emissions data. Such additional information can be a part of the weighted cost equation used within the optimization process.
