Applied Physics and Mathematics Annotation << Back A SIMPLIFIED MATHEMATICAL MODEL OF THE INTERNAL COMBUSTION ENGINE A.A. MOISEEV A simplifi ed mathematical model of the internal combustion engine, designed to simulate the eff ect of himmotologicheskih factors on the dynamics of the engine and its effi ciency. The model is based on the ratio for the balance of the engine power and load of the AC generator, and due to friction in the pistoncylinder group. Its peculiarity is that to simulate the dynamics of the pressure in the cylinder using the indicator diagram of the engine, and mixed friction approximated by Guernsey-Stribeck. The latter, in particular, to evaluate the impact of wear and dirt couples the piston - cylinder lubricating ability and effi ciency of the engine. Key words: internal combustion engine, internal carburetion, heat generation, gas exchange, throttle, doser, reducer, crank mechanism, quality control, quantity control.
