Title: Supercharger and compressor
Inventor: UCHIDA HIROSHI
IPC: F04D27/02
Filed: 2007-07-19
Abstract: <P>PROBLEM TO BE SOLVED: To expand the operable range of a turbo compressor while suppressing the generation of the surging of the turbo compressor without complicating the structure of the turbo compressor.  <P>SOLUTION: The pulsation of a period T1 is forcibly imparted to an intake gas flow of the turbo compressor 20 so as to fluctuate the operation state of the turbo compressor 20 between a stable area and a surging area at the period T1 by repeating the open/close operation of a solenoid controlled valve 25 arranged at an outlet 20b of the turbo compressor 20 at the period T1 shorter than a period T0 of air current vibration when the surging is generated. This allows the operation of the turbo compressor 20 while avoiding the generation of the surging since the operation state of the turbo compressor 20 instantaneously enters the surging area and is transferred to the stable area before the generation of the surging even if a time average flow amount of the turbo compressor 20 is a small flow amount which is included in the surging area.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Title: Device for acquiring degree of deterioration of catalyst of internal combustion engine
Inventor: AOKI KEIICHIRO
IPC: F02D45/00
Filed: 2007-07-20
Abstract: <P>PROBLEM TO BE SOLVED: To accurately acquire degree of deterioration of a catalyst even if sensor response varies in a device changing over air fuel ratio of gas in an upstream of the catalyst to lean or rich, and acquiring degree of deterioration of the catalyst based on timing of changeover of output of an air fuel ratio sensor in the downstream of the catalyst to a value indicating lean or rich.  <P>SOLUTION: This device calculates a reduction gradient of the maximum oxygen storage quantity Cmax with respect to increase of air flow rate Ga based on two maximum oxygen storage quantities Cmax and two air flow rates Ga estimated respectively when air flow rates Ga are two different values. The reduction gradient is larger as degree of deterioration of a catalyst 53 is larger. When degrees of deterioration of the catalyst 53 are same, the reduction gradients tend to be same even if degree of responses of change in output of downstream side air fuel ratio sensors 67 vary. Consequently, the calculated reduction gradient can be a value accurately indicating degree of deterioration of the catalyst 53.  <P>COPYRIGHT: (C)2009,JPO&INPIT
