ABSTRACT:
This invention relates to an event timing apparatus for an internal combustion engine, and more particularly to an improved control arrangement for a fuel injection and ignition arrangement. In accordance with this invention, a timing detecting arrangement is disclosed having a timing correcting circuit for correcting deviations between the actual timing measurements made and the true, desired timing signal required for accurate operation of the fuel injection system. Thus, a fuel injection system and ignition system is provided that is able to provide accurate crank angle timing measurements with reference to which crank chamber pressure and other measurements may be made, in spite of possible manufacturing and/or assembling variations in the timing measuring means. The way in which the manufacturing or assembling of variations are measured is also disclosed.
