Patent Number Title Of Patent Date Issued
5311852 Method for detecting fuel blending ratio May 17, 1994
In a fuel blending ratio detecting method, a first blending ratio of the methanol in the fuel supplied to an internal combustion engine is detected by a blending ratio sensor; an air/fuel ratio feedback compensation coefficient computed on the basis of an output of an O.sub.2 sensor is
5267163 Method for detecting blending ratio of mixed fuel to be supplied to combustion chamber of intern November 30, 1993
A method includes a step of calculating an estimated blending ratio of a mixed fuel supplied to a combustion chamber of an internal combustion engine and a following equation is effected in this step to derive the estimated blending ratio:where t is an integer,n is a first delay coeffici
5263464 Method for detecting fuel blending ratio November 23, 1993
In a fuel blending ratio detecting method, a first blending ratio of the methanol in the fuel supplied to an internal combustion engine is detected by a blending ratio sensor; an air/fuel ratio feedback compensation coefficient computed on the basis of an output of an O.sub.2 sensor is
5197451 Method for detecting fuel blending ratio March 30, 1993
A fuel blending ratio detecting method is provided which includes a feedback computing compensation coefficient K.sub.FB on the basis of an air/fuel ratio responsive output V.sub.o of an O.sub.2 sensor, computing a feedback learned value K.sub.LRN on the basis of the feedback compensatio
5195497 Method for detecting fuel blending ratio March 23, 1993
A fuel blending ratio detecting method is provided wherein a feedback compensation coefficient K.sub.FB is computed on the basis of an air/fuel ratio responsive output V.sub.o of an O.sub.2 sensor, and a current blending ratio compensation coefficient K.sub.B is multiplied by a peak
5163407 Method for detecting fuel blending ratio November 17, 1992
A fuel blending ratio detecting method computes a control blending ratio on the basis of blending ratio information generated from a blending ratio sensor or air/fuel ratio information generated from an O.sub.2 sensor, and when the engine is stopped, the control blending ratio detected a
5158058 Air-fuel ratio feedback control method for a multi-fuel internal combustion engine October 27, 1992
An air-fuel ratio feedback control method for a multi-fuel internal combustion engine using a dual O.sub.2 sensor system is provided, in which the concentration of oxygen in exhaust gas on the upstream side of an exhaust gas purifier is detected, a value corresponding to the detected
5144916 Vehicular engine cooling apparatus September 8, 1992
Provided according to the present invention is a vehicular engine cooling apparatus comprising cooling fan means for cooling at least one of an engine and an environment of the engine, the engine being operated with use of any of two or more different fuels and a mixed fuel formed of a
5109821 Engine control system May 5, 1992
In an engine using fuel mixture of gasoline and methanol, the present control system compensates a detection value of a blend ratio sensor with a detection value of a knock sensor, or causes trouble detecting means to detect a failure of the blend ratio sensor and memories the blend rati
