Comparison of fuels in combustion engines

Equipment of an engine for quick change of fuels in the fuel cycle. Example of application: Testing the efficiency of fuel additives or of other kinds of fuel pretreatment. Two kinds of fuel are changed in the engine repeatedly without mixing. Thus also small differences in the specific consumption, the emissions and further values measured at the engine which are influenced by the fuel will be clearly visible. The engine is charged by a coupled braking dynamometer (engine test bed). At the test bed, different load conditions may be adjusted. The reproducibility of the experiments is secured by the speed stabilisation and the automatic gravimetric determination of the specific fuel consumption of the MP Computer.
