Influence of the combined method of power regulation implementation way on spark ignition engine’s mechanical losses and fuel economy

Y. Gutarevych S. Rychok

The article considers ways to evaluate the influence of various implementations of the combined method of power regulating of the engine with spark ignition on mechanical losses and fuel economy. The object of research is a method of power regulating of a spark-ignition engine. The purpose of the study is to evaluate different ways to improve the combined method of power regulating of a spark-ignition engine. A theoretical study of various implementations of the combined method of power regulating of the engine with spark ignition. The study took into account the results of previous studies in this area. According to the results of this study, it is established that when the group of cylinders is deactivated with free air intake, mechanical losses can be reduced and fuel efficiency can be improved by 5...11% in comparison with disabling only a fuel supply with unchanged gas exchange system.
