摘要： The invention relates to a system for indicating the ignition advance in the distributor of an engine where the speed of the engine increases. The system indicates this ignition advance for a particular cylinder by producing a ramp voltage to a particular level for the particular cylinder regardless of changes in ignition speed and by producing a triggering signal when the ramp voltage reaches a particular level which is adjustable. When the triggering signal is produced, an output indication of the ignition advance is provided. This output indication may be provided by a meter of by the strobing of the relative positions of a stationary marker and a marker on a flywheel driven by the engine.

摘要： A ramp voltage is provided to a particular amplitude upon each occurrence of an ignition signal for a cylinder in a multicylinder engine. The slope of the ramp voltage is changed as the rate of occurrence of the ignition signals in the multicylinder engine varies. When the amplitude of the ramp voltage reaches the particular level, the ramp voltage is terminated until the occurrence of the next ignition signal. A sweep is produced in accordance with the ramp voltage. When the frequency or angular velocity of the multicylinder engine is to be tested, the ramp voltage is produced at the same slope as in the previous paragraph. However, the ramp voltage is produced to a level dependent upon the rate of occurrence of ignition signals. The level of this ramp voltage indicates the rate of occurrence of the ignition signals. The level of the ramp voltage is also measured in each cycle of sequential firing of the multiple number of cylinders, upon a failure of a particular one of the cylinders to fire in each cycle, to indicate the speed of the engine.

摘要： A system is provided for displaying ignition signals of an internal combustion engine. In one mode, sweep signals are produced in synchronism with the particular recurring characteristics of the ignition signals for the different signals in an internal combustion engine. In a second mode, sweep signals are produced in synchronism with the particular recurring characteristics of such ignition signals until the occurrence of the ignition signal prior to a particular ignition signal which is to be displayed. At such a time a sweep is initiated prior to the occurrence of the particular ignition signal. This sweep is maintained until a time after the occurrence of the particular ignition signal. The particular ignition signal is displayed during this sweep.
