Title: Air fuel ratio control system of internal combustion engine
Inventor: KATO TATSUNORI
IPC: F02D41/14
Filed: 2003-06-06
Abstract: <P>PROBLEM TO BE SOLVED: To improve emission and drivability by restricting the range of variation to the rich and lean sides in the air-fuel ratio.  <P>SOLUTION: A correction coefficient FAF in an air-fuel ratio feedback control can be changed as desired in response to output voltage VOX1 of an oxygen sensor, vehicle speed SPD, and gear position GP. Thus, even though it takes a long time for exhaust gas from the internal combustion engine to reach the oxygen sensor due to restrictions, etc., of layout constitution, the range of variation to the rich and lean sides in the air-fuel ratio can be restricted. Further, since the center of control in the air-fuel ratio can be shifted to the rich side, the amount of NO<SB>x</SB>-discharge in the high-speed region in the vehicle speed SPD can be reduced. In an internal combustion engine of a big valve-overlap, drivability in the low-speed range in the vehicle speed SPD can be improved.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To correctly presume an operation state (a humidification state of an electrolyte membrane, supply states of hydrogen and oxygen, and the like) of a fuel cell regardless of the temperature distribution in the fuel cell.  <P>SOLUTION: Multiple cells are distributed to a plurality of cell groups; an output voltage of every cell group is measured; and the operation state of the fuel cell 10 is diagnosed based on the average voltage of the output voltages, voltage dispersion of the output voltages, and the output voltages. When the average voltage is in a predetermined range, and there is a cell group having the output voltage outside a second predetermined range, it is presumed that water in a passage is excessive. When the average voltage is outside the first predetermined range and the voltage dispersion is in a third predetermined range, it is presumed that the electrolyte membrane is dry. When the average voltage is outside the first predetermined range, and the voltage dispersion is outside the third predetermined range, it is presumed the supply amount of a fuel gas is insufficient.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide a hood stopper capable of improving pedestrian protecting performance when a pedestrian contacts with a hood.  <P>SOLUTION: The hood stopper 10 has a lower part 16 and an upper part 18, and a locking groove 20 is locked to an attaching hole 14 of a radiator support 12 to provide a mounted state thereof. The outer diameter of a hood abutting surface 24 which hood 22 hits is set smaller than the inner diameter of the attaching hole 14, and a slit 26 is formed in the upper part 18. Therefore, when a downward contact load F beyond a predetermined value acts on the hood 22, the hood stopper 10 falls out of an attaching hole 18. As a result, displacement stroke of the hood 22 is secured, and the pedestrian protecting performance is improved.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Filed: 2003-06-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide an induction heating cooker which prevents response failure in temperature detecting of a temperature sensor during energization to an induction heating coil.  <P>SOLUTION: When a heating level is 'high' in turning a power switch on, and the temperature detected by a thermistor 7 is lower than a specified temperature (50°C), a controller 8 controls the amount (heating power level) of current supply to an induction heating coil 5 to be decreased to an 'intermediate' level until the temperature detected by the thermistor 7 reaches to the specified temperature (50°C). This prevents response failure in temperature of a pan 6 detected by the thermistor 7 during the passing of the current to the induction coil 5, and can control accidental rapid temperature rise of the pan 6, which a user does not intend to happen.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
