Title: Air/fuel ratio detector
Inventor: KOJIMA TAKAO
IPC: G01N27/419
Filed: 1987-05-12
Abstract: PURPOSE:To detect an air/fuel ratio accurately, by a method wherein one of two detection elements is operated as oxygen concentration battery element and the other as oxygen pump element and an air fuel ratio signal is outputted corresponding to the concentration of oxygen in an emission. CONSTITUTION:By a current supply system 74, a detection element acting as oxygen concentration battery element 20 also operates as oxygen pump element 10. When a pump current Ip=0 as flowing through the oxygen pump element 10, a voltage Vs generated in the oxygen concentration battery element 20 is changed according to a voltage Vh applied to heaters 30 and 40. Therefore, a constant pump current Ipo is obtained at a specified voltage value Vso regardless of a heater voltage Vh. Thus, an air/fuel ratio signal outputting circuit 76 controls a pump current flowing through an oxygen pump element 10 so that the voltage generated in the oxygen concentration battery element 20 reaches Vso and an air/fuel ratio is detected from a value of the current.

Abstract: PURPOSE:To perform positive transmission and avoid the thermal damage of a transmission belt by providing such flexibility for an interlocking member on the speed change member side as to be movable and fitting a spring for energizing the speed change member side interlocking member to move onto the belt winding diameter decelerating side. CONSTITUTION:The rod connecting hole 20 of an interlocking member 10 is formed into a slotted hole as well as an automatic tension spring 21 is fitted across an interlocking rod 11 and the member 10.
