Abstract

PURPOSE:To improve exhaust emission from an engine without deteriorating its output performance, by variable controlling an intake state and performing feedback control of a combustion delay period. CONSTITUTION:Combustion timing is arithmetically operated by a combustion timing detector circuit 43 on the basis of outputs from a cylinder pressure sensor 38 and crank angle sensor 41. This combustion timing signal is input to a combustion delay detector circuit 44 with an ignition timing signal 37, and a clock signal, from input of the signal 37 to input of the combustion timing signal, is counted to obtain a combustion delay signal, then the combustion delay siganl of several cycles is averaged by an equalizer circuit 46 and input to a comparator circuit 48. Here the signal is compared with a reference value corresponding to a target combustion period in accorddnce with an operating condition from a target value table 47, and this result controls on-off proportion of a control pulse to a solenoid valve 25 through an exhaust gas recirculating (EGR) amount control circuit 49, to change negative pressure fed to an EGR valve 26 and control an EGR amount.
