Abstract: The basic requirements of the OBD II/EOBD systems for diesel combustion engines are present in the paper. The necessity of combustion process parameters monitoring in the engine is pointed. There are shown the results of the UTD-20 engine tests concerning the FFT analysis of quick–changeable measurements of temporary rotational speed and temporary accelerations of engine crankshaft for the purposes of fuel combustion process monitoring. MONITOROWANIE JAKOŚCI PROCESU SPALANIA TRAKCYJNEGO SILNIKA O ZS W ASPEKCIE WYMAGAŃ EOBD Streszczenie W referacie przedstawiono podstawowe wymagania systemow OBDII/EOBD dla silnikow spalinowych o ZS. Wskazano na koniecznośc monitorowania parametrow procesu spalania w silniku. Podano wyniki badan silnika UTD-20 dotyczące analizy FFT szybkozmiennych pomiarow chwilowej predkości obrotowej chwilowych przyspieszen walu korbowego do celow monitorowania procesu spalania paliwa.

TL;DR: In this paper, a system for built-in instrumentation, applied to a fleet of bus vehicles, is evaluated as one element of a continuing program to improve the effectiveness and efficiency of bus maintenance operations.
Abstract: A system for built-in instrumentation, applied to a fleet of bus vehicles, is evaluated as one element of a continuing program to improve the effectiveness and efficiency of bus maintenance operations. This paper describes the peculiarities of bus maintenance, the evaluation process, tradeoffs related to test system requirements versus benefits derived, and how the instrumentation system design was tailored from a military to a commercial application. The results of the evaluation are presented along with a review of other consideration factors including fuel shortage, fleet capital investment spiral, and cost and availability of maintenance personnel. /GMRL/
