| titleOfInvention | Air-fuel ratio detecting means assessment |
| abstract | Objective: To provide an air-fuel ratio estimation detecting means which eliminates the use of an oxygen sensor or the like to directly detect an air-fuel ratio by estimating an air-fuel ratio of combustion gas based on a signal output of a pulser rotor and is captured. A first crank angle speed ω1 in a first predetermined range τ1 overlapping an upper compression dead point is calculated, and the first crank angle speed ω1 is subtracted from a mean engine speed NeA to calculate a first change amount Δω1. Also, a second crank angle speed ω2 is calculated in a second predetermined range τ2 overlapping a lower combustion dead point, and the first crank angle speed ω1 is subtracted from the second crank angle speed ω2 to calculate a second change amount Δω2. A comparison and an assignment are made between a slope of a straight line shown in the IMEP-ηc map (43a) which shows the relationship between an indicated mean effective pressure and a degree of loading of the engine under conditions that an ignition timing is set to one Value is set at which a maximum torque is generated when the throttle opening and the engine speed are constant, and a slope of Δω1 / Δω2. |
