Sensor arrangement for engine

Abstract

An engine includes an improved sensor arrangement that can decrease the possibility of damage to sensors relating to fuel injection control. The engine includes a cylinder block defining first and second banks of cylinder bores extending separately from each other. Pistons reciprocate within the respective cylinder bores. Cylinder head members are arranged to close respective ends of the first and second banks of the cylinder bores. The cylinder head members define combustion chambers together with the cylinder bores and the pistons. An air induction system is arranged to introduce air to the combustion chambers. The induction system includes 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 define first and second intake passages, respectively, through which the air flows. Fuel injectors are arranged to spray fuel for combustion in the combustion chambers. First and second sensors are arranged to sense a condition of the intake air. A control device is configured to control the fuel injectors based upon signals of the first and second sensors. The first sensor is disposed at the first intake unit. The second sensor is disposed at the second intake unit.
