Class Information
Number: 123/406.74
Name: Internal-combustion engines > Spark ignition timing control > Mechanical or hydraulic link to throttle valve or accelerator
Description: Subject matter wherein the regulating means for varying spark ignition timing includes either a mechanical or hydraulic linkage connection to either (a) a means for varying the cross-sectional area of a combustible mixture forming conduit, or (b) to a device which is manually adjusted by an operator for controlling the rate of rotation of an engine output shaft.
