ABSTRACT:
Exhaust gas is sampled from an internal combustion engine operated disconnected from the transmission elements, thus braked by its inertia and internal losses only.
Before running the test it is important to find out the positions, at which the fuel supply means ensures idle running and maximum fuel supply, respectively. A monitoring device is designed to find out these positions, and then to run a test cycle between those positions. The monitoring device may include means for running, prior to the actual test, a short conditioning program at the engine, to ensure that the same has attained a desired normal temperature, when the test starts.
