摘要

Basic issues concerning the working cycles of piston, four-stroke, internal combustion engines are discussed in the paper. It presents the methodology worked out to determine the value of the effective heat emission coefficient in combustion with the use of theoretical and real diagrams of the engine working cycles. The proposed methodology was based on Sabathe theoretical working cycle, in which the heat is conveyed to the working medium in the cylinder partially at constant volume q′_1 and partially at constant pressure q″_1. The way of coefficient ξ determination presented in the paper can be used for the determination of the real values of ξ for various operating conditions of piston self-ignition internal combustion engines. The values of ξ thus obtained enable us to conduct more accurate theoretical calculations and analyses of real indicator diagrams of IC engines.
