Modeling the friction of the heat engine for its performance

Friction losses due to piston rings account for approximately 20% of all mechanical losses in engines. Reduced friction results in higher efficiency, lower fuel consumption and reduced emissions. The goal of this study is to develop a low-friction engine design to improve engine efficiency without compromising oil consumption, wear or cost. These are desirable goals today for engine manufacturers, as they tend to improve engine performance in a time when there is increasing talk of global warming issues. The determination of the instantaneous fluctuation of the parameters of the thermal engine depends on several components representing the environment of the engine, which have complex connections. The determination of the instantaneous friction torque is influenced by the angular determination of the crankshaft during the engine cycle. .
