Patent JP-S60111050-A (JP)
Title: Air-fuel ratio controller
Inventor: SUZUKI FUJIYUKI
IPC: F02D41/16
Filed: 1983-11-21
Abstract: PURPOSE:To keep off the promotion of improper lean mixture due to a follow- up delay in feedback control, by performing open-loop control for a carburetor early at a transient state in time of deceleration in the feedback controlling type carburetor. CONSTITUTION:Especially, idle system air bleed control for a feedback controlling type carburetor using an exhaust sensor 30 takes place. In this case, at deceleration, when an idle switch 32 is on and a value out of an engine speed detector 34 is avobe the specified one as well as when output of an exhaust sensor 30 is lean signal after detection, feedback control is stopped and open- loop control is carried out instead. At this time, it is shifted up to a specified rich ari-fuel ratio point at relatively high speed whereby the promotion of improper lean mixture due to a follow-up delay in a decelerating transient state produced at a feedback control system is prevented from occurring.

Inventor: IMAZEKI TAKASHI
IPC: F16H48/22
Filed: 1987-08-31
Abstract: PURPOSE:To obtain both the prevention of consumption in current, pumping loss, and noise and the improvement in responsiveness in the generation of a transmitting torque by limiting the generating timing of clutch engaging force while preventing controlling hunting. CONSTITUTION:A friction clutch element (e) for generating a transmitting torque which is variable in accordance with an engaging force from the outside (d) is provided midway in a driving system for transmitting a driving force from an engine (a) to front and rear wheels (b), (c) or right and left wheels (c), (c). In this structure, an initial engaging force controlling means (f) detects the difference in rotating speed between front and rear wheels (b), (c) or between right and left wheels (c), (c) and, when the difference in rotating speed is below a set value, it makes an initial engaging force to the friction clutch element (e) zero while, on the other hand, at the time of above the set value, it gives the initial engaging force to the friction clutch element (e) for a defined time. Thereby, the generating time of a clutch engaging force can be limited while preventing controlling hunting.
