An Innovative Electronic Diesel Engine Management System

A review of electronic diesel governor design objectives is given. Voest-Alpine Automotive's (VAA) design guidelines are explained, and a new governor type 4 is presented. The 185×142×47 mm3 unit (appr. 1/3 the size of comparable 1987 vintage gear) is applicable to most injection pumps using linear or rotary actuators and associated control valves. It features all functions required in high performance diesel vehicles. An exceptionally low IC count of seven (no custom designs), a power dissipation of typically 6 W, advanced CMOS and VMOS circuitry and the unique multi-microcomputer architecture MµCA (R) ensure safety, reliability as well as the future addition of complex functions. A second-generation programming computer is described and data taken from typical applications are shown.
