| 20090145109 | Catalyst degradation diagnosis device and diagnosis method for internal combustion engine - The oxygen storage capacity preceding a previous oxygen storage capacity and the previous oxygen storage capacity of each of an upstream catalyst and a downstream catalyst are measured, and a present oxygen storage capacity of the downstream catalyst is measured. Then, sulfur poisoning of the upstream catalyst and the downstream catalyst is detected on the basis of an oxygen storage capacity change amount of each of the upstream catalyst and the downstream catalyst from the oxygen storage capacity preceding the previous one to the previous oxygen storage capacity, and the oxygen storage capacity change amount of the downstream catalyst from the previous oxygen storage capacity to the present oxygen storage capacity. The presence/absence of the sulfur poisoning can be accurately detected by utilizing the difference between the manners of sulfur poisoning of the two catalysts. | 06-11-2009 |
| 20100211290 | ABNORMALITY DIAGNOSTIC DEVICE AND ABNORMALITY DIAGNOSTIC METHOD FOR MULTICYLINDER INTERNAL COMBUSTION ENGINE - A fuel injection amount from fuel injection valves is actively controlled and an input air-fuel ratio is caused forcibly to oscillate. A system from the fuel injection valves to the air-fuel ratio sensor is simulated by a first order delay system, and a gain and time constant are identified on the basis of the input air-fuel ratio relating to the model and an output air-fuel ratio obtained from the air-fuel ratio sensor. The presence of an air-fuel ratio abnormal variation is diagnosed on the basis of whether or not the identified values of the gain and the time constant are less than a first and second predetermined values respectively. | 08-19-2010 |
| 20100307135 | APPARATUS AND METHOD FOR DIAGNOSING CATALYST DETERIORATION - A catalyst deterioration diagnosing apparatus is provided with means for performing stoichiometric feedback control on the air-fuel ratio based on at least output from an upstream air-fuel ratio sensor provided upstream of a catalyst, means for measuring the oxygen storage capacity of the catalyst, and means for correcting the measured value of the oxygen storage capacity based on at least the output behavior of a downstream air-fuel ratio sensor provided downstream of the catalyst during the stoichiometric feedback control. The measured value of the oxygen storage capacity is corrected using the output behavior of the downstream air-fuel ratio sensor during stoichiometric feedback control. The diagnostic is performed after eliminating the effects from sulfur by correcting the measured value to a value corresponding to when low sulfur fuel is used, which makes it possible to prevent an erroneous diagnosis from being made. | 12-09-2010 |
| 20110005207 | CONTROL DEVICE - A control device applied to a system having an engine configured such that an expansion ratio can be changed is characterized to comprise an expansion ratio acquisition part for acquiring the expansion ratio, and a temperature estimation part for estimating a temperature of an exhaust gas discharged from the engine or a member positioned in a passage for the exhaust gas. | 01-13-2011 |

| 20100062248 | COMPRESSION-MOLDED PRODUCT USING PLANT MATERIAL AND METHOD FOR MANUFACTURING THE SAME - First, wood or bamboo is crushed to obtain wood powder with an average grain size of 5 μm to 100 μm. Next, the wood powder is put in a first mold, and a first compression molding step is carried out under the conditions that, for example, a temperature is 160° C. and a pressure is 30 MPa. Thus, a temporary molded body is obtained. Subsequently, the temporary molded body is immersed in a flame retardant and a surface of the temporary molded body is impregnated with the flame retardant. Thereafter, the temporary molded body is put in a second mold, and a second compression molding step is carried out under the conditions that, for example, a temperature is 200° C. and a pressure is 100 MPa. At this time, ingredients such as lignin and a hemicellulose are separated from the wood powder, and function as an adhesive. For this reason, pieces of crushed material are firmly bonded with each other so as to be integrated into a single body. Thus, a compression-molded product with a predetermined shape is obtained. | 03-11-2010 |
