Вплив параметрів процесу зворотного стиску на індикаторні показники поршневого пневмодвигуна

Problem. Problem One of the pressing problems of modern automotive industry is the creation of economical and environmentally friendly vehicles. One of the ways to increase these indicators is through the use of hybrid cars, in which the additional engine operates in those modes where the internal combustion engine operates inefficiently (starting from a standstill, acceleration modes, movement with low loads, for example, in traffic jams). The use of hybrid engines allows not only to reduce fuel consumption, but also to significantly reduce emissions of toxic substances in exhaust gases. Goal. The goal of the work is to study the influence of the parameters of the back compression process on the indicator indicators of a piston air engine. Methodology. Using the analytical method, the influence of the degree of reverse compression on the indicator indicators of the air motor was calculated using a static model. The mathematical apparatus MatLab was used in the calculation. Results. The relationship between the degree of reverse compression of the bellows and the indicator work and the indicator air flow rate is revealed. Graphs of the dependence of these quantities are given. Originality. A mathematical model for a pneumatic engine with a valve air distribution mechanism as part of a hybrid vehicle power plant is proposed.Practical value. The use of the proposed method for calculating the working processes of an air motor will allow determining the necessary indicator indicators at the stage of its design.
