ОПТИМІЗАЦІЇ РОБОЧИХ ЗОН ПОТУЖНОСТІ ДВЗ ВІДПОВІДНО ДО ПОСТІЙНИХ КОНТУРІВ ЕФЕКТИВНОСТІ

This article examines the impact of changing the operating power zones of internal combustion engines on dynamic performance using sports cars as an example. The use of a mathematical model of the internal combustion engine's operation in the studied vehicles plays a significant role in determining their energy performance during operation in different modes. Furthermore, the use of engine power zone data with constant efficiency contours facilitates the determination of rational engine loading and the achievement of the vehicle's maximum possible efficiency. Optimization of the power operating zones of internal combustion engines ensures the alignment of load modes with real operating conditions. This makes it possible to minimize energy losses and enhance the stability of the vehicle’s dynamic characteristics. In this way, a balance is achieved between maximum engine efficiency and fuel economy.
