| Popis: | This paper presents an unconventional approach in a fast estimation of the overall engine inertia based on engine testing under transient condition (acceleration and deceleration) with simultaneous in cylinder working process analysis and friction losses estimation. The presented procedure is based on a single slow dynamic slope full load engine speed sweep test which, coupled with a simple lumped-mass engine dynamometer model, provides correct overall engine inertia estimation. Compared with the more conventional approaches in deriving information on engine inertia, besides its speed and accuracy, presented procedure provides more in depth information on both engine’s dynamic response and friction as a surplus. |
