Method for operating internal combustion engine, particularly on test stand, involves determining respective temperature of fluid in two of fluid guides downstream of heat transfer compound in separating manner

摘要

The method involves determining the respective temperature of the fluid in two of the fluid guides (6,7,8) downstream of a heat transfer compound in a separating manner. An error signal is generated by a functional value in the excess of a threshold value, where the functional value is calculated from the determined temperature. A crankcase of an internal combustion engine (2) has multiple crank chambers (3,4,5), in which a cylinder assembly is arranged in a sectional manner.
