Investigations of automobile engine accelerations require a new approach (reply to G.N. Zlotin)
// Dvigatelestroyeniye. — 1989. — ¹ 11. — P. 57–58.
Key words:
engines.
A critical analysis is given of the G.N. Zlotin's review "Again of the coefficient of the engine operation under non-steady state conditions" (Dvigatelestrojenie N 12, 1988, p. 55, 75). Unfounded objections are shown, expressed by G.N. Zlotin in his review of the paper by V.M. Archangelski, S.A. Prishvin, S.S. Epstein "Energetic parameters of carburettor engines at their accelerations under full power conditions" (Dvigatelestrojenie, N 4 1988, p. 9–11, 23). A new approach is roved to be used for investigation of accelerations. That means that one should not consider the engine parameters as time local, one should take into account the general engine parameter variation during all the transient process of the acceleration.
