Patent
Exhaust gas purification device for an internal combustion engine
Hiroshi Sawada,Junichi Kako +1 more
TL;DR: In this paper, the authors measured the length of the stoichiometric air-fuel ratio period of the exhaust gas flowing out from the NOX occluding and reducing catalyst.
Patent
Apparatus and method for detecting abnormal air-fuel ratio variation among cylinders of multi-cylinder internal combustion engine
TL;DR: In this paper, an apparatus for detecting abnormal air-fuel ratio variation among cylinders of a multi-cylinder internal combustion engine was proposed, which includes a catalyst element (11) that oxidizes hydrogen contained in exhaust gas to remove the hydrogen.
Patent
Catalyst deterioration detecting apparatus and method
TL;DR: In this article, an upstream side catalyst and a downstream side catalyst are disposed in an exhaust passage, and the air-fuel ratio is forcibly oscillated and the oxygen storage capacity of the upstream side catalysts is detected.
Patent
Air-fuel ratio feedback control system having a single air-fuel ratio sensor downstream of a three-way catalyst converter
Mitsuhiro Nada,Hiroshi Sawada +1 more
TL;DR: In this article, a coarse-adjusting term is calculated integrally in accordance with the output of the air-fuel ratio sensor, and a fine adjusting term was calculated differentially at every reversion of the actual air fuel ratio.

TL;DR: In order to study a diffusive behavior of Li+ in Li intercalated graphites, muon spin relaxation spectra for C6Li and C12Li synthesized with an electrochemical reaction between Li and graphite in a Li-ion battery are measured.
