Document Type and Number:
Japanese Patent JPS5174118
Kind Code:
A
Abstract:
An engine revolution counter gives signals corresponding to ignition frequencies to one input of a first digital counter. An air flow meter gives signals corresponding to air volume in the air intake manifold to an oscillator whose output is fed to the second digital counter input. A second digital counter receives signals from an oscillator corresponding to engine temperature. The injection signal is taken from a timing switch which together with the first and second counter results determine the injection dwells. A signal storage unit is provided between the output of the first counter and the input of the second counter and triggered by an transfer gate which receives a signal from the clock pulse generator.
