In determining the specific fuel consumption rating of gasoline-driven single-cylinder engines, three problems occur: test stand vibrations, shifting of the direct coupling mechanism, and inability to maintain constant dynamometer loads for any length of time. A small portable test stand was designed, minimizing the vibrations. A steelflex coupling fastened by means of two set screws, one on top of another, absorbed the shock loads and prevented coupling shifting. A water pressure valve installed at the inlet to the dynamometer maintained a constant water pressure. A deflector mounted within the dynamometer in turn insured the rotor being completely surrounded by water, allowing a constant load to be maintained on the dynamometer.
