Patent ID: 6886540

Claim:
An internal combustion engine comprising a cylinder block defining first and second banks of cylinder bores extending separately from each other, pistons reciprocating within the respective cylinder bores, cylinder head members arranged to close respective ends of the first and second banks of the cylinder bores, the cylinder head members defining combustion chambers together with the cylinder bores and the pistons, an air induction system arranged to introduce air to the combustion chambers, the induction system including first and second intake units with the first intake unit allotted to the first cylinder bank and with the second intake unit allotted to the second cylinder bank, the first and second intake units defining first and second intake passages, respectively, through which the air flows, fuel injectors arranged to spray fuel for combustion in the combustion chambers, first and second sensors arranged to sense a condition of the air flowing in the induction system, and a control device configured to control the fuel injectors based upon signals of the first and second sensors, the first sensor being disposed at the first intake unit, and the second sensor being disposed at the second intake unit such that only the first sensor is used to sense a condition of the air flow in the first intake passage and only the second sensor is used to sense a condition of the air flow in the second intake passage, the first sensor being of a different type than the second sensor so as to sense a different air flow condition through the induction system than the air flow condition sensed by the second sensor and different from any other air flow sensor in the second intake passage.
