Abstract: 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.

Abstract: AUTOMATIC ANTIKNOCK MONITORING AND/OR ADJUSTING APPARATUS HAVING DETONATION TESTING ENGINE OPERATED ON FUEL TO BE MONITORED OR ADJUSTED, AND AUTOMATIC CONTROLS TO CHANGE ITS COMPRESSION RATIO IN RESPONSE TO CHANGES IN DETONATION INTENSITY, WITH OCCASIONAL RESETTING AGAINST RESULTS USING A REFERENCE FUEL. MAXIMUM KNOCK FUEL-AIR RATIO IS USED AND THE AUTOMATIC CONTROLS CAN ALSO CONTROL THE ADDITION OF HIGH ANTIKNOCK BLEND INGREDIENT TO THE FUEL.
