THE CONCEPT OF DISPLACEMENT RATIO AND OPTIMAL FILLING
Abstract
Power properties of piston internal combustion engines are depending on the cylinder's loading with air. In general, at the conclusion of the process of gas exchange in the cylinders of the engine there are a mixture consisting from air, fuel, recycling gases and residual gases. All properties of the engine are a function of the composition of this mixture.
The proposed article presents the thermodynamic backgrounds of the alternative assessment and calculation of piston internal combustion engine's cycle, based on traditionally used in all fields of science and technology fractions of components in a mixture.
The object of the proposed article is the finding of expressions, which take into account the effect on the loading of fuel used and of excess air ratio, (to this end was introduced the concept of a coefficient of displacement), as well as the determination of the coefficient of volumetric efficiency, comply with the maximum loading in the absence of the new change's losses.
