Abstract
A throttle sensor senses the position of an associated throttle shaft in order to determine the position of a corresponding throttle valve. The position of the throttle sensor is positioned in the engine to reduce the girth of engine. In one embodiment, the throttle sensor lies to the side of a throttle linkage which interconnects a plurality of throttle valves. The throttle sensor and throttle linkage are arranged on a side of an intake manifold opposite a side on which fuel injectors of the engine are located. In another embodiment, the throttle sensor lies at an upper end of the intake manifold and is coupled to a common, vertically orientated throttle shaft that operates a plurality of throttle valves.
Claims16
A marine engine comprising an induction system including a plurality of throttle devices having a plurality of throttle passages, each of the throttle devices being positioned in a row such that the flow axes through the throttle passages lie generally parallel to one another, a throttle shaft extending through the plurality of throttle passages and supporting a plurality of throttle valves, each throttle valve being positioned within a respective throttle passage, the throttle shaft controlling an opening degree of the plurality of throttle devices within the throttle passages, a throttle sensor coupled to the throttle shaft, each of the throttle devices communicating with an intake manifold of the engine, a bracket supporting the throttle sensor and being attached to the intake manifold, and at least one elastic coupler that secures the bracket to the intake manifold.
