Title: Air fuel ratio control device of internal combustion engine
Inventor: HASEGAWA JUN
IPC: F01N3/24
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of the emission to a minimum while the temperature rise of the exhaust gas in the high load condition is suppressed. SOLUTION: In an exhaust pipe 12 of an internal combustion engine 1, an A/F sensor 26 is arranged on the upstream side of a three dimensional catalyst 13, and a downstream side O2 sensor 27 is arranged on the downstream side. A CPU 32 judges whether or not the running condition of the engine is in the high load range based on the temperature of the exhaust gas. The CPU 32 sets the target air fuel ratio on the rich side in the linear detection range of the air fuel ratio by the downstream side O2 sensor 27 in the beginning into the high load range, and the air fuel ratio feedback control is realized using the target air fuel ratio. When the load level becomes high, the CPU 32 sets the target air fuel ratio on the rich side according to the temperature of the exhaust gas, and the air fuel ratio feedback control is realized using the target air fuel ratio. In addition, when the rich width is deviated from the detection range of the A/F sensor 26, the CPU 32 open controls the increase in the fuel amount.

Filed: 1987-06-05
Abstract: PURPOSE:To simplify the construction by furnishing a coil electrode at one of the rods, and allowing the breaking current to flow in this coil electrode only at the time of breaking. CONSTITUTION:Current I flowing into the stationary side rod 4 of a vacuum breaker flows out to an external conductor via a stationary side are electrode 6, a movable side are electrode 8, and a movable side rod 5. When a break signal is given, this rod 5 is driven downward, and an arc 11A is generated in the gap between the electrode 8, 6. Then the electrode 8 moves apart from the one 6, and the arc 11A extinguishes. When the gap at this time attains the break gap L, the break current I flows from a coil electrode 10 to the electrode 8 as the gap l1 is smaller than L, to generate an arc 11B in the gap l1. A magnetic field H by current I intersects in right angle to the arc 11B, and an electromagnetic force F is applied to magnetically drive the arc 11B in the circumferential direction within the gap l1. Thus extinction is accomplished.
