ABSTRACT:
An ignition timing control device which optimizes ignition timing even at low atmospheric pressures. This ignition timing control device comprises a detecting means for detecting when an exhaust gas recirculation (EGR) device should be actuated or not. When the detecting means indicates the EGR device is not actuated, but the quantity of intake air and engine speed are within a range of values where the exhaust gas recirculating device would be actuated at low altitudes, such ignition time is made to be optimum by delaying the timing.
