It is well known to diesel engineer. that the heat release pattern is one of the most important factors affecting engine performance. Thorough research in heat release pattern has materially helped the progress in high. speed diesel engine development. This paper is based on the research conducted at KAIST and Daewoo Heavy Industry last year. The purpose of this paper is to determine the heat release pattern in combustion chamber of MANM type, the famous low-noise engine.
Thermodynamic cycle simulation was performed using Whitehous-Way's heat release pattern with modified coefficients and Annand's heat transfer model. Instantaneous temperature and pressure of gas in cylinder could be det ermined by the numerical solution of simultaneou. s equation of mass conservation, equation of energy conservation, and state equation of ideal gas. Calculated results were compared with measured values in some details emphasizing upon the factors affecting rate of heat release.
The agteement was fairly good and revealed why M type should have lower burning velocity at the early part of combustion inspite of high injection rate. Additional results by parametric studies were given in relation to fuel injection conditions for further application to engine development.
