Assessment of engine operation with the use of an operation indicator based on test bench results of a Robin-Subaru Ex17 engine

Paper presents results of an experimental verification of the method of quantitative evaluation of engine operation, presented in the literature, exemplified by a low-power internal combustion piston engine. In accordance with such interpretation, engine operation may be presented as a physical quantity defined as operation indicator. The paper presents results of preliminary tests, processed in that aspect, carried out on an engine test bench. The results have been used as a classifying measure of the engine reliability state.
