Title: Exhaust purifier in internal combustion engine
Inventor: HARA SEINOSUKE
IPC: F01N3/22
Filed: 1978-07-11
Abstract: PURPOSE:To eliminate CO, HC, NOx in such a way that air is cyclically supplied into exhaust in rich air-to-fuel ratio, and repeated condition is engendered between ternary atmosphere and oxidized atmosphere. CONSTITUTION:Secondary air introduced from outer air by an air pump 7 is intermittently supplied to an exhaust passage 5 by operation of an electromagnetic valve 12 controlled by a frequency controller 13. On the other hand, though the mixed air in slight rich air-to-fuel ratio is supplied from a carburetor 3 into an air intake passage 2, which is burned in the internal combustion engine 1, and exhaust is made into slight rich air-to-fuel ratio streaming through an exhaust passage 5, because of cyclically intermittent supply of secondary air, it becomes repetition between slight rich air-to-fuel ratio and lean air-to-fuel ratio, when it comes into a ternary catalytic device, repeating condition is engendered between ternary atmosphere and oxidized atmosphere, to effectively eliminate toxic three ingredients of CO, HC, NOx.

Abstract: PURPOSE:To color and display synthesized screen information in a position range on a screen based upon position data by composing the synthesized screen information with digital R(red), G(green), and B(blue) signals selected with the position data. CONSTITUTION:The R, G, and B signals from a personal computer 1 are converted into 8-bit parallel signals by S/P converting circuits 10, 20, and 30.
