Abstract

This paper presents a new concept of a rotary engine, with combustion chamber at constant volume. In this context, we present a comprehensive theoretical study on the combustion process that takes place at constant volume in the combustion chamber. A mathematical model was developed to describe the combustion process. The conducted theoretical study allowed comparing the thermodynamic parameters describing the combustion process for two fuel mixtures. Air - petrol vapors mixture and additional hydrogen feed were considered. A main attention has been paid to maximum values of the pressure in the combustion chamber as it has a direct influence on engine torque. Also, the study shows the advantages of using constant volume burning and the differences that occur with the use of the two types of fuel, as well as the evolution of the pressure and temperature within the combustion chamber. This allows evaluating the thermal load and determining the mechanical stresses to which the components of the proposed rotary engine are subjected.
