GEL1110000 - Ignition Misfire Generator

A completely new version of misfire generating equipment ("MisGen3") has been introduced to replace the existing equipment developed over the last decade. Currently, this equipment is used in development, calibration and testing of the on-board misfire detection for OBDII. The same need should arise in other markets as Europe and other regions adopt regulations similar to those in the U.S. This new generation misfire generator addresses the following concerns:

	Ignition systems of some recent engines are not fully compatible with the existing misfire generators. In the past, ignitions system have sometimes required modifications to the misfire generators to maintain compatibility. This redesigned misfire generator is fully compatibility with current and past ignition systems.
	The new equipment provides greater flexibility in setting the misfire pattern, which is essential to ensuring proper operation of the detection algorithm over all misfire scenarios. The control pendant now incorporates LEDs (one per cylinder) to visually indicate each misfire as it is generated.
	The new box outputs "S_KILL", a special version of the KILL signal (the misfire logic signal) suitable for recording by data acquisition systems. This signal has been synchronized with PIP so as to indicate precisely in the data file which ignition events were induced misfires. Without this stabilization to PIP, the KILL signal is unsuitable for this purpose because of the varying phase shift (# of PIPs) between it and the actual misfire event in the data.
	The new misfire generator should also be compatible with engines from other manufacturers (up to 12 ignition coils), as has been requested by engineers on several occasions in the past. The box only needs connections to the driven sides of the ignition primaries, as well as power and ground. Of course, incompatibilities may arise, but are not considered likely.
