Title: Fuel injection control device of internal-combustion engine
Inventor: SATO KUNIHIKO
IPC: F02D41/00
Filed: 1984-08-07
Abstract: PURPOSE:To maintain purifying property of a catalyst, by controlling an injection quantity of fuel by an air-fuel feedback correction coefficient obtained in accordance with the concentration of a specific component in exhaust gas while controlling amplitude of the correction coefficient and its frequency in accordance with a detected flow of intake air. CONSTITUTION:A control device, while it is in feedback control, reads input data corresponding to the output of an O2 sensor 20 from a random access memory (RAM) 48 to be compared with a reference value, setting a rich flag to 1 when air-fuel ratio is in a rich side for the theoretical value while to 0 when the air-fuel ratio is in a lean side. Next the device, immediately after the flag is set to 0 from 1 or reversely inverted to be set, inputs a fixed value R to X for increasing a change quantity of a correction coefficient FAF, while the device, if the flag is not immediately after being inverted, reads input data of an intake air flow Q from the RAM48, obtaining an integration constant K in accordance with Q to be input to X. Next the device, calculating FAF  FAF-X in case of the flag being 1 while FAF FAF+X in case of the flag being 0, stores the obtained FAF in the RAM48. That is, exhaust gas is purified by controlling the integration constant K of the correction coefficient FAF in accordance with the intake air quantity Q.

Filed: 1986-07-14
Abstract: PURPOSE:To prevent miserasion of a received message despite a service interruption caused in a holding mode by detecting the amount of a recording tape fed in a rewind mode after a message received from a caller is recorded and recording the data signal on the tape feed amount on the recording tape. CONSTITUTION:When a message is recorded, a control means 12 delivers a control signal to an output terminal P1 to control a tape feed means 1 in a rewind mode and rewind a recording tape 2 back to its initiation.
