Abstract

PURPOSE:To enable to prevent a knocking at a low temperature and increase torque at a high temperature by controlling ignition timing through detection of a suction air temperature, in a captioned method controlling the ignition timing through a suction air flow or suction air negative pressure and a revolution. CONSTITUTION:Detecting data for both a suction air temperature and a revolution speed are taking in by CPU38 according to an interruption request signal from a timing signal forming circuit 32, and the most suitable ignition timing theta0 is obtained. A warm up correction and a suction air temperature HUA correction through a sensor 15 are carried out to this theta0. Suction air data stored in RAM44 through the CPU38 are taken in by this HUA correction for comparison with a detected temperature HUA, correction ignition timing angles, for example, DELTAtheta1=2 deg. in case HUA >=70%, DELTAtheta1=1 deg. in case 70>= HUA >=50%, DELTAtheta1=1 deg. in case 50>= HUA >=20% and DELTAtheta1=-2 deg. in case 20%>= HUA are obtained for correction. Therefore, a torque is increased at a high temperature and generation of a knocking can be prevented at a low temperature.
