“A Successful Electronic Ignition System thru Fundamental Problem Analysis” 740154
For 1974, Ford Motor Company is providing, as standard equipment, a solid state ignition system on all 400 CID and 460 CID engines as well as on all California vehicles equipped with 200 through 351 CID engines. This paper explains the Ford solid state ignition system and the objectives and design philosophy that was used in the development of the system. Further, a review of the design and production validation test plans is discussed. With this background, specific examples of the effectiveness of complete problem analysis for fundamental cause and corrective action is presented in addition to control methods and evaluation of corrective action. This problem analysis system allowed this automotive electronic product to go into production with a high degree of confidence in meeting the reliability goals.
