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 7):
The control system of the internal combustion engine as set forth in  claim 1 , further comprising:\n a variable valve timing mechanism which controls a closing timing of an intake valve; and an EGR valve which opens and closes an EGR passage which connects an engine intake passage and the engine exhaust passage, wherein the controller is further configured to:\n calculate an amount of correction of the output value of the oxygen sensor or the air-fuel ratio sensor or a target air-fuel ratio for compensating for a deviation amount between the output value of the oxygen sensor or the air-fuel ratio sensor and an actual air-fuel ratio of the exhaust gas due to a change of the hydrogen concentration in the exhaust gas due to a change of the closing timing of the intake valve, based on the closing timing of the intake valve; \n calculate an amount of correction of the output value of the oxygen sensor or the air-fuel ratio sensor or the target air-fuel ratio for compensating for the deviation amount between the output value of the oxygen sensor or the air-fuel ratio sensor and the actual air-fuel ratio of the exhaust gas due to a change of the hydrogen concentration in the exhaust gas due to a change of an opening degree of the EGR valve, based on the opening degree of the EGR valve; and \n correct the output value of the oxygen sensor or the air-fuel ratio sensor or the target air-fuel ratio based on the amount of correction which is calculated on the basis of the closing timing of the intake valve, and the amount of correction which is calculated on the basis of the opening degree of the EGR valve.
