Abstract:
Methods and systems are provided for measuring exhaust gas recirculation (EGR) distribution among individual engine cylinders. In one example, a method may include fluidly coupling a plurality of intake runners of an engine to a vacuum pump, diverting a portion of intake charge gas from the intake runner to a gas composition sensor with the vacuum pump, measuring an oxygen concentration of the diverted intake charge portion with the gas composition sensor, and estimating an EGR concentration of the intake charge based on the measured oxygen concentration.

Claim (Index 16):
The method of  claim 15 , further comprising, during a second condition, including when an oxygen concentration of the first intake gas is being measured with the first intake gas composition sensor,\n measuring an oxygen concentration of the second intake gas with the second intake gas composition sensor.
