Title: Input changeover device
Inventor: ADACHI YASUSHI
IPC: H03K17/00
Filed: 1989-06-23
Abstract: PURPOSE:To select an input receiving a signal automatically and to save number of input switching control terminals by applying initial setting of a counter with an input signal and using an output of the counter so as to select plural inputs automatically. CONSTITUTION:Contacts of an input switching circuit 3 are selected by the polarity of an output Qn. With the output Qn selected at an L level, the contacts of the circuit 3 are set to be at the position of an input terminal 1. Thus, while a signal whose L level longest period is at a prescribed value of the input terminal 1 is inputted to an output terminal 4, a signal inputted to the input terminal 1 is outputted. Thus, while the signal is inputted to the input terminal 1, the switching circuit 3 selects the input terminal 1 regardless of the state of the input terminal 2. As a result, suppose that a signal is simultaneously inputted to the input terminals 1, 2, the signal inputted to the input terminal 1 is selected with priority. As a result, the input selection is not required and in the case of adopting an integrated circuit, number of input switching control terminals is reduced.

Abstract: PURPOSE:To deal with control for all the engine speed and in an entire load region, by making structure that the two-stage control of intake control and control of the amount of EGR or exhaust gas recycling is performed in a feedback group, based on the differential pressure between the under flow pressure of an intake throttle valve of an intake tube and the pressure of an exhaust tube. CONSTITUTION:For a first step intake control prosecuted by a controller 14, the differential pressure between the intake pressure of under flow of an intake throttle valve 6 and the exhaust pressure of an exhaust tube 3 is detected by a pressure differential sensor 8, and a valve 6 is controlled so as to make the differential pressure the aimed differential pressure responsive to the engine speed and the load at the time. After the differential pressure is made as the aimed one by intake control, EGR control is prosecuted by controlling an exhaust gas recycling valve 7 by the controller 14 to make an oxygen concentration in an exhaust tube 3 detected by an oxygen concentration sensor 9 the aimed concentration responsive to the engine speed and the load at the time. In this way, engine control for low speed, a low load range, or high speed, a high load range can be compensated by intake control and be dealt with through all the drive ranges.
