Abstract
A throttle body for an internal combustion engine of an automobile includes a housing defining a plurality of spaced apart, separated intake passages, a plurality of throttle valves, a plurality of throttle shafts and a drive mechanism. The plurality of throttle valves is rotatably disposed in the plurality of intake passages. Each throttle shaft is adapted to support one of the plurality of throttle valves. A drive mechanism is operably connected to the plurality of throttle shafts to rotate the plurality of throttle valves. The drive mechanism includes a single motor and a gear arrangement. The gear arrangement is configured to drive at least two throttle shafts of the plurality of throttle shafts at varying speeds. The gear arrangement selectively and sequentially opens at least two throttle valves of the plurality of throttle valves at varying rates.
