Abstract:
A control system of an internal combustion engine includes an S/V ratio changing mechanism able to change an S/V ratio of a combustion chamber and a detection device having an output value changing in accordance with a hydrogen concentration in exhaust gas, which increases along with an increase in the S/V ratio, the internal combustion engine being controlled by the output value of the detection device. Further, the output value of the detection device or a parameter relating to operation of the internal combustion engine is corrected in accordance with the S/V ratio of the above S/V ratio changing mechanism.

Claim (Index 1):
A control system of an internal combustion engine comprising:\n an S/V ratio changing mechanism that changes an S/V ratio of a combustion chamber; a three-way catalyst which is arranged in an engine exhaust passage; an oxygen sensor or an air-fuel ratio sensor that is arranged upstream of the three-way catalyst in the engine exhaust passage and that is to output an output value changing in accordance with a hydrogen concentration in exhaust gas, which increases along with an increase in the S/V ratio; and a controller configured to control an air-fuel ratio of gas corresponding to the output value of the oxygen sensor or the air-fuel ratio sensor to be leaner so that the air-fuel ratio of gas which flows into the three-way catalyst is closer to a stoichiometric air-fuel ratio when the air-fuel ratio of gas corresponding to the output value of the oxygen sensor or the air-fuel ratio sensor is low than when the air-fuel ratio of gas is high, and so that a lean changing degree of the air-fuel ratio of gas corresponding to the output value of the oxygen sensor or the air-fuel ratio sensor is larger when the S/V ratio is high than when the S/V ratio is low.
