Evaluation of the efficiency of thermal insulation of the combustion chamber according to the load characteristics of a diesel engine

Abstract Prospects for the development of diesel engine building are seen in a consistent increase specific indicators due to forcing on average effective pressure with simultaneous decrease loss fuel combustion heat, thermal insulation chamber and use exhaust gas energy. All these measures taken bring real thermodynamic cycle closer theoretical adiabatic cycle. This explains appearance terms adiabatic, semiadiabatic, partially even superadiabatic. The existing estimates effectiveness chambers level adiabatization were based qualitative rather than quantitative indicators, as result which achieved effects interpreted by various researchers ambiguously. introduction uniformity methods, criteria evaluating efficiency using heat working makes it possible determine not only level, but also predict future industry, confirms relevance problem.
