Mathematically it is expressed as, BSFC Fuel mass flow rate(. Tran, “ Engine calibration: multi-objective constrained optimization of engine maps,” Optimization and Engineering, vol. Brake specific fuel consumption is the ratio of a mass flow rate of the fuel supplied to the engine to the brake power obtained at a crankshaft and it indicates how efficiently the fuel is used to produce brake power.

The optimization results show that the power increases to 13%, BSFC decreases to 11% and the cost operation decreases to 23% compare with existing design variables Root Mean Square Error (RMSE) of ANN modelling is 0.021 kW for power and 0.00032 kg/kW.hr for BSFC. The optimized variables are engine speed (rpm), Air Fuel Ratio (AFR), Mass Fuel Flow (MFF), Intake Pressure (IP), Intake Air Temperature (IAT), Combustion Start (CS) and Throttle Angle (TA). The objective function in this paper is to maximize power, minimize the Brake Specific Fuel Consumption (BSFC) and minimize the operational cost. The ANN weights were determined by utilizing Levenberg-Marquardt algorithm. Phenomena of brake specific fuel consumption and volumetric efficiency in CI engine by modified intake runner length. A gasoline engine was simulated using Ricardo Wave commercial software to acquire data for training and testing the proposed ANN. The modelling of gasoline engine was built using Multi-Layer Perceptron - Artificial Neural Network (MLP-ANN). The brake-specific fuel consumption (BSFC) measures an engines performance (efficiency). The first one is: fix the engine speed and find the torque associated with the minimum. This paper discussed optimization of gasoline engine using Killer Whale algorithm. In my understanding, there are two ways to go to compute the best BSFC line of an internal combustion engine. In Formula Society of Automotive Engineering (SAE) competition, the design of efficient and powerful combustion engine is required. ![]()
