| 20090216429 | CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE - When either one of two injectors of each cylinder becomes abnormal, a control device performs failsafe control of performing increase correction of injection quantity of a normal injector. If actual injection quantity is restricted with the maximum injection quantity that can be injected by the normal injector during the execution of the failsafe control, the control device restricts duty of an actuator of an intake air quantity adjustment mechanism (such as a throttle opening degree), thereby restricting intake air quantity to intake air quantity that does not cause melting damage of a catalyst. Thus, increase of deviation of an air-fuel ratio toward a lean side can be inhibited, and the melting damage of the catalyst can be prevented. | 08-27-2009 |
| 20100036593 | FUEL INJECTION CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE - An alcohol concentration sensor detects an alcohol concentration in fuel that is supplied to an internal combustion engine. A fuel injection quantity is controlled in accordance with a detection value of the alcohol concentration that is detected by the alcohol concentration sensor. When a temperature of the fuel, which is detected by a fuel temperature sensor or estimated from intake air temperature etc., is equal to or lower than a predetermined limit temperature, the detection value of the alcohol concentration, which is detected by the alcohol concentration sensor, is memorized as a memorized value of the alcohol concentration. When the temperature of the fuel is higher than the predetermined limit temperature, the fuel injection quantity is controlled by using the memorized value of the alcohol concentration instead of using the detection value, which is currently detected by the alcohol concentration sensor. | 02-11-2010 |
| 20100050982 | FUEL SUPPLY CONTROL APPARATUS - A fuel supply control apparatus for an engine includes an alcohol concentration detector and an engine temperature detector. The apparatus increases an amount of fuel supplied to the engine as the detected alcohol concentration becomes higher. The apparatus increases the amount of fuel as the engine temperature becomes lower and as the alcohol concentration becomes higher. The apparatus feed-back corrects the amount of fuel by using a correction value such that an actual air-fuel ratio becomes a theoretical air fuel ratio. The apparatus determines that water is mixed with fuel when the correction value during a cold operational state indicates leaner than the lean value of the correction value used during a warm operational state. The apparatus reduces the increased amount of fuel when water is mixed with fuel. | 03-04-2010 |
| 20100263647 | LIQUID CONCENTRATION MEASURING DEVICE - A microcomputer of an alcohol concentration sensor reads a first measurement value corresponding to a first frequency and reads a second measurement value corresponding to a second frequency. The microcomputer calculates a difference between the first and second measurement values. The microcomputer performs stuck failure abnormality determination when a state where the difference between the measurement values is equal to or smaller than a predetermined value continues. The microcomputer outputs a PWM signal of a specific frequency, which is different from a frequency in a case of a normality, to an engine ECU. Thus, a failure of the alcohol concentration sensor can be surely determined. | 10-21-2010 |
| 20100264937 | LIQUID CONCENTRATION SENSING DEVICE - A capacitance sensing section senses a capacitance between first and second electrodes. A temperature sensing section senses fuel temperature. A microcomputer functions as a concentration sensing section and senses a concentration of ethanol contained in fuel based on the capacitance sensed by the capacitance sensing section and the temperature sensed by the temperature sensing section. The microcomputer functions as an abnormality detecting section and performs abnormality determination to determine that an abnormality has occurred in the capacitance sensing section when the capacitance sensed by the capacitance sensing section does not change and the temperature sensed by the temperature sensing section changes. Since a dielectric constant has such a temperature characteristic that the dielectric constant changes with the temperature, the abnormality detecting section can detect occurrence of the abnormality in the capacitance sensing section. | 10-21-2010 |

| 20080236427 | PLANOGRAPHIC PRINTING PLATE, AND APPARATUS AND METHOD FOR MANUFACTURING THE SAME - According to the present invention, the droop height is set to 25 to 70 μm, a knife having an acute angle of 70° or more is used as the lower knife, and the level difference angle of the lower knife is set to 5° or less. Thereby, it is possible to prevent stain from being formed on a planographic printing plate, while securing the predetermined droop height. At the same time, it is possible to suppress the generation of a burr, and to prevent a flaw from being caused at the time when the planographic printing plates are stacked. | 10-02-2008 |
