  • Electrical Control Of Air Or Fuel Supplied To Internal-Combustion Engine (AREA)

Abstract

PURPOSE: To decrease the variation of torque in the case when starting re-injection without the danger of engine stop due to the delay of the startng of re-injection, by gradually increasing the quantity of fuel fed from value lower than quantity computed when starting re-injection after cutting fuel.
CONSTITUTION: An injection quantity computing circuit 10 computes the quantity of fuel injected suitable for an operation condition at the point of time on the basis of the quantity of air sucked, water temperature and the number of revolution, and the signal S5 is put out to a multiplying circuit 14. When starting re-injection, a revolution number integrating circuit 12 is triggered and integrates the number of revolution after starting re-injection, and an integrating signal S7 is put out. A correcting coefficient computing circuit 13 puts out a correcting coefficient signal S8 gradually increasing in response to the integrating signal S7, the signal S8 is sent out as a correcting injection quantity signal S9 by the multiplying circuit 14, and a fuel injection valve 8 is driven through a drive pulse S10 of a drive circuit 15 corresponding to the signal S9, thus controlling the quantity of fuel injected.
