IPC: F02D41/14
Filed: 1977-11-16
Abstract: PURPOSE: Internal combustion engine of air fuel ratio return type equipped with skip mechanism by which appropriate skip effect is obtained in accordance with base air-fuel ratio.  
     CONSTITUTION: Valve body 90 and valve seat 92 are added in diaphragm chamber 56 of secondary air controlling valve 28 and skip route 36 is connected to port 94 placed under valve seat 92, and negative pressure delay valves 96 and 98 are respectively placed in the routes between electromagnetic valve 42 and diaphragm chamber 54 and between electromagnetic valve 44 and diaphragm chamber 58.  Because the opening area of skip route 36 changes in connection with the displacement of valve body 62 of secondary air controlling valve 28, in case of overconcentration of base air-fuel ratio where the output characteristic of O 2  sensor differs  widely from air excess rate λ=1, the amplitude of air-fuel ratio by the skip becomes  large. On the other hand the base air-fuel ratio is near λ=1, the skip rate becomes  small and purification efficiency is improved.
