    摘要： Liquid fuels have their knock characteristics monitored by knock test engine operating alternately on the fuel to be tested and on a reference fuel. The difference in knock intensities can be used to control the in-line blending of the test fuel. Test engine has carburetor with fuel-level-determining device to which stream of test fuel is continuously fed faster than required by engine, excess fuel is diverted away from engine by overflow or suction take-off. Fuels can be cooled on way to engine. Compression ratio of knock test engine and/or signal indicator can have automatic adjustment when engine operates on reference fuel so as not to require attention of an operator.

    摘要： AUTOMATIC KNOCK TESTING OF GASLINE WITH ENGINE HAVING AUTOMATIC COMPRESSION RATIO CONTROL THAT CHANGES COMPRESSION RATIO TO MAINTAIN PREDETERMINED KNOCK INTENSITY, IS EFFECTED WITH QUICKER AND SIMPLER MZXIMUM KNOCK FUELAIR RATIO SEARCH THAT FIRST LOWERS FUEL-AIR RATIO AND THEN INCREASES IT AT A FAIRLY RAPID RATE, THE INCREASING BEING TERMINATED WHEN THE COMPRESSION RATIO CONTROL STOPS CALLING FOR A DECREASE IN COMPRESSION RATIO, AND THEN AN ADJUSTMENT IS MADE FOR OVERSHOOTING OF THE FUEL-AIR RATIO INCREASE. ALTERNATIVELY THE INCREASE IN FUEL-AIR RATIO CAN BE EFFECTED IN STEPS AT LEAST ABOUT 10 SECONDS APARTS, THESE

    STEPS BEING TERMINATED WHEN THE COMPRESSION RATIO DECREASE STEPS PAUSE FOR AT LEAST ABOUT THE SAME LENGTH OF TIME AS THE SPACING BETWEEN FUEL-AIR RATIO INCREASE STEPS. NO ADJUSTMENT IS NEEDED WITH THIS ALTERNATIVE.
