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 oriented throttle shaft that operates a plurality of throttle valves.
Claims20
A marine engine including an induction system comprising a plurality of throttle devices which communicate with intake passages of an engine intake manifold, a throttle linkage that interconnects said throttle devices to synchroize the operation of said throttle devices, each throttle device comprising an operator that controls an opening degree of a throttle valve of said throttle device, at least one fuel injector communicating with each intake passage of the intake manifold, said fuel injectors positioned on a side of all of the intake passages opposite of said throttle linkage, and a throttle sensor coupled to one of said throttle operators on the same side of the intake passages as the throttle linkage.
A marine engine including an induction system comprising a plurality of throttle devices and an equal number of intake passages, each throttle device communicating with only one of the intake passages, a throttle linkage which interconnects said throttle devices so as to synchronize the operation of said throttle devices, each throttle device comprising an operator that controls an opening degree of a throttle valve of said throttle device, at least one fuel injector injecting fuel into each intake passage, said fuel injectors positioned on a side of the throttle devices opposite of said throttle linkage, and a throttle sensor coupled to one of said throttle operators on the same side of the throttle devices as the throttle linkage.
