Title: Air-fuel ratio controlling method for gas engine
Inventor: IMOTO SEIJI
IPC: F02D19/02
Filed: 1983-07-25
Abstract: PURPOSE:To attain stable operation of an engine, by preventing occurrence of cycling by stopping for a predetermined while after changing the air-fuel ratio to a lower value, and obtaining an optimum incremental threshold value by correcting the incremental threshold value reduced from the opening of a throttle valve at the time of changing the air-fuel ratio according to the difference of the engine speed before and after changing the engine speed for increasing or decreasing the same. CONSTITUTION:Opening thetan1 of an air-fuel ratio switching throttle valve meeting the engine speed is selected from a table by detecting the engine speed by a sensor 11. Then, the actual opening thetam of the throttle valve is detected by a valve opening detector 30 and it is compared with the opening thetan1. In case of thetam>=thetan1, theoretical air-fuel ratio control is executed by closing an EGR valve 17 and setting an air-fuel ratio control mechanism into operation. Thereafter, a certain interval time is taken, and after passing of waiting time, the engine speed N1 and the actual throttle valve opening thetam at the time are detected to prepare the valve opening thetan2, obtained by subtracting several steps from the valve opening thetam as a threshold value for switching the air-fuel ratio from lambda= 1.0 to lambda=1.4. Thus, since an optimum throttle valve opening meeting the engine load can be obtained regardless of the change of the load/throttle valve opening characteristics, it is enabled to prevent occurrence of cycling.
