Title: Ignition timing control device for internal combustion engine
Inventor: IWAKURA YOICHI
IPC: F02P5/15
Filed: 1986-10-25
Abstract: PURPOSE:To prevent the reduction in torque and the worsening in emission or the like, by correcting the spark advance value in the direction in which the ignition timing is delayed, when the differential pressure between the atmospheric pressure and the intake air pressure is less than the operating pressure of an exhaust gas recirculation control valve, so that the exhaust gas recirculation is not carried out. CONSTITUTION:On the basis of the detected value of a pressure sensor 13 being commonly used for the atmospheric pressure detecting means and for the intake pressure detecting means by the changeover control of a changeover valve 14, if the differential pressure between the atmospheric pressure and the intake air pressure is greater than the operating pressure of an EGR valve 8, the EGR valve 8 is operated to carry out the exhaust gas recirculation. In this case, the final spark advance value is set on the basis of the basic spark advance value calculated by the detected values of various sensors and the like, so that an ignition plug 25 is electrified. On the other hand, when the differential pressure between the atmospheric pressure and the intake air pressure is less than the operating pressure of the EGR valve 8, the EGR valve 8 is not operated, and an EGR correction value is added to the basic spark advance value, and the final spark advance value is set in the direction in which the ignition timing is delayed. Accordingly, an optimum ignition timing conforming to the combustion speed outside the execution area of the EGR is set. Thus, the reduction in torque and the worsening in emission or the like can be prevented.

Title: Air-fuel ratio feedback control method for internal combustion engine
Inventor: KASHIWABARA SHIGETO
IPC: F02D41/14
Filed: 1988-10-08
Abstract: PURPOSE:To enhance accuracy in an air-fuel ratio control, when the air-fuel ratio of a mixture to be supplied is feedback-controlled by using the mean value of coefficients which change with the output of an exhaust gas density detector, by stopping the calculation of the mean value in a feedback control region where the load of an engine is within a prescribed range. CONSTITUTION:During the operation of an internal combustion engine 1, an ECU 5 controls a fuel injection valve 6 on the basis of various engine parameter signals. In other words, when the operation of the engine 1 is in an air-fuel ratio feedback control operation region, the mean value of coefficients which change with the output of an O2 sensor 14 is calculated, and the feedback control of air-fuel ratio is carried out by using at least the calculated mean value. When the load of the engine 1 is less than a first prescribed value, the feedback control is stopped, and the control for increasing the air-fuel ration of the mixture is carried out. In this case, it is so contrived that the calculation of the mean value of coefficients is stopped in the air-fuel ratio feedback control operation region where the load of the engine 1 is greater than the first prescribed value and is less than a second prescribed value.

Title: Dirt compensating device for toner concentration controlling sensor
Inventor: ARAI TOMIO
IPC: G03G15/08
Filed: 1986-10-29
Abstract: PURPOSE:To prevent lowering in image density even when a toner concentration controlling sensor is contaminated with toner, by providing a means which controls the light emitting quantity of the light emitting element of the sensor so that the output of the light receiving element of the sensor which receives reflecting light from the no-image forming surface of a photosensitive drum can become a prescribed value. CONSTITUTION:When a copying device is shipped or the photosensitive drum 8 of the device is exchanged, voltage of an output terminal 21 at the no-image forming area of the drum 8 is adjusted and the correction data is stored in a ROM as 1st sensor correcting standard data. Thereafter, the current reflectivity data of the no-image forming area is fetched and compared with the 1st correcting standard data and sensor correcting data is outputted from a DA converter 24. Therefore, when a sensor 17 becomes dirty, the reflectivity data become lower and a difference is produced between the data and 1st correcting standard data. Therefore, lowering in reflectivity corresponding to the difference is compensated. Thus sensor dirt is automatically corrected and toner concentration control can be performed smoothly.
