Abstract: An adaptor for use in conjunction with an internal combustion engine having a capacitor discharge ignition system provides a substitute high voltage pulse coincident with the high tension pulse of the engine ignition system but having a period which is sufficiently prolonged to enable a conventional engine analyzer to be used to measure the usual engine parameters.
Abstract: An apparatus for generating a synchronizing signal for a selected cylinder of a multi-cylinder engine having a double ended coil ignition system, including a comparator for identifying a real ignition pulse on the ignition device associated with the selected cylinder and a discriminator for identifying a real ignition signal on the coil energizing that ignition device and circuitry to produce a synchronizing signal only when the two coincide.

Abstract: A method or apparatus whereby the primary windings of a multi-coil ignition system may be connected to a common terminal to provide a composite signal identifying the start of each cylinder ignition sequence. Means may also be provided for inhibiting the generation of ignition pulses by selected coils.
