Optimization methods play a key role in the design and control of modern powertrains in the current automotive industry. Emphasis is placed primarily on the implementation of optimization algorithms and predictive models that are used by engine control units. These are intended to ensure effective control of torque, fuel consumption and vehicle dynamics in real time depending on driving conditions and driver requirements. The aim of the paper was therefore to describe the results of research conducted in the field of multi-parametric optimization of fuel consumption and performance of a four-cylinder atmospheric internal combustion engine with a cylinder capacity of 1,390 cm3. Optimization of the operating parameters of the powertrain, such as fuel consumption and performance, was carried out with a view to the possibility of implementation into control algorithms and predictive models applicable to engine control units. The benefit of the proposed optimal operating mode of the powertrain, aimed at minimizing fuel consumption and maximizing its output power, is the achievement of high operating efficiency while maintaining favorable dynamic characteristics of the engine.
