Abstract: | A structure of a mathematical model of the unsteady gas flow phenomena in an internal combustion engine is discussed. The emerging inhomogeneous non-linear system of partial differential equations is solved by the Method of Differences as proposed by Lax and Wendroff (1960). The numeric solution was implemented in a program system PROMO which permits the complete examination of unsteady gas flow problems in multi-cylinder IC engines.An analysis of the actual exhaust system of a six-cylinder automobile engine is presented as well as a synthesis of a new, improved exhaust system. |
