  • Lead assembly for a distributorless ignition interface
    Patent number: 4937527
    Abstract: A distributorless ignition interface unit for use with an engine analyzer for analyzing an internal combustion engine includes a processing circuit which responds to analog signals representing true and wasted firings for the cylinders of the engine under test to determine the number of cylinders of the engine and the polarity of the firing of each cylinder and to then characterize the engine by determining the order of the true and wasted firing signals produced during an engine cycle and for producing a parade pattern of true or wasted secondary signals for application to the engine analyzer.
    Type: Grant
    Filed: June 12, 1989
    Date of Patent: June 26, 1990
    Assignee: Snap-on Tools Corporation
    Inventors: John C. Sniegowski, Craig F. Govekar, Dennis G. Thibedeau, Ron D. Geisler
