Inventor: YAMADA TATSUO
IPC: F02B3/06
Filed: 1990-07-25
Abstract: PURPOSE:To obtain high regeneration efficiency of a filter and prevent crack and flame-breaking of the filter by providing a means for controlling an opening of an exhaust throttle valve so as to maintain an exhaust temperature in the vicinity of an inlet of a trap filter in the range of a prescribed regeneration temperature at the time of regenerating of the filter. CONSTITUTION:In the exhaust passage 3 of a diesel engine 1, a trap filter 5 with catalyst for collecting particulates is interposed, and also an exhaust throttle valve 6 is interposed downstream thereof. A map date for controlling the opening of an exhaust throttle valve 6 is stored in the memory circuit in a controller 9 so as to maintain the exhaust temperature in the vicinity of the inlet of the trap filter 5 in the range of a prescribed regeneration temperature at the time of regenerating of the filter 5. All of high temperature exhaust is led into in the filter 5, and flows nearly equally in the whole of the filter 5, then discharged toward the downstream side, so that it is possible to promote combustion process of collected particulates, and equalize temperature distribution in the whole of the filter 5. It is thus possible to obtain high regeneration efficiency of the filter 5, while preventing effectively crack and flame-breaking of the filter 5.

Abstract: PURPOSE:To read the data at an always stable and fast speed by reducing the electric potential difference of a pair of column lines after the address inputted to the line decoder is changed and the prescribed time passes. CONSTITUTION:When one line is selected by the output of a row decoder 66, plural memory cells 64 and dummy memory cells 65 are simultaneously driven. By the output a column decoder 67, one transistor 68 is made into an on condition selectively, and through the transistor 68, one column 61 is linked to one side input terminal of a sense amplifier 69. When the electric potential of the selected column line 61 and a dummy column 62 is sufficiently opened, the data are detected by the sense amplifier 69 and the data Dout are outputted from an output buffer 73. After the data Dout are outputted from an output buffer 73, the electric potential of the line 63 is reduced to the value with the low electric potential as well as the above-mentioned. When the electric potential of the line 63 is reduced, the value of the on-resistance of the dummy memory cell 65 is increased. Thus, the electric potential of the dummy column 62 is advanced and the electric potential difference in the mutual section of the column 61 and the dummy column 62 is reduced.
