Patent number: 8594906Abstract: Methods and systems for diagnosing a multiple cylinder engine are provided herein. An exemplary method of diagnosing an internal combustion engine system having a multi-cylinder internal combustion engine is described. In one example, cylinder air-fuel imbalance is determined from the squared value of a difference of two values.Type: GrantFiled: March 26, 2010Date of Patent: November 26, 2013Assignees: Mazda Motor Corporation, Ford Global Technologies, LLCInventors: Hajime Suetsugu, Kenji Kojima, Tetsushi Hosokai, John D.

Patent number: 8573042Abstract: This disclosure provides a method for measuring an output characteristic of an air fuel ratio sensor based on an output value of the air fuel ratio sensor at the time of changing a fuel injection amount. Under a predetermined condition, an increase in the fuel injection amount is started from a particular cylinder and the increase in the fuel injection amount is continued for a given time period, or a decrease in the fuel injection amount is started from the particular cylinder and the decrease in the fuel injection amount is continued for the given time period. Therefore, the output characteristic of the air fuel ratio detecting module can be measured with sufficient accuracy, regardless of the contacting strength of emission gas for every cylinder against the air fuel ratio detecting module.Type: GrantFiled: November 11, 2010Date of Patent: November 5, 2013Assignee: Mazda Motor CorporationInventors: Hajime Suetsugu, Makoto Matsumae

Patent number: 8365587Abstract: This disclosure provides a method of detecting a cylinder-to-cylinder gap abnormality of an air fuel ratio with sufficient accuracy according to an individual specificity of an air fuel ratio detecting module. Particularly, the method may be used for an engine to detect the cylinder-to-cylinder gap abnormality of the air fuel ratio of supplied air fuel mixture abnormality based on an output value of a linear O2 sensor. Under a first predetermined condition, an output characteristic of the sensor is measured. The measured output characteristic is compared with a reference characteristic set in advance to calculate a correction value for correcting the sensor output according to the individual specificity of the sensor. Subsequently, under a second predetermined condition, the sensor output value is corrected based on the calculated correction value to detect the abnormality based on the corrected output value of the sensor.Type: GrantFiled: November 11, 2010Date of Patent: February 5, 2013Assignee: Mazda Motor CorporationInventors: Hajime Suetsugu, Kenji Kojima
