A manifold, such as an intake manifold or a fuel injection manifold, for use in an internal combustion engine, as well as a method of operating such an engine, are disclosed. In at least one embodiment, the manifold includes an input end capable of being coupled at least indirectly to an air input device, first and second intake tubes linking the input end to first and second exit ports, respectively, and a first communication channel linking the first and second intake tubes. The communication channel has a first width that is substantially less than a second width of at least one of the first and second intake tubes, and the communication channel links upper portions of the first and second intake tubes, while lower portions of the intake tubes remain separated by a wall.

Disclosed herein is a breather assembly for use in an internal combustion engine and a method of operating an internal combustion engine. In at least one embodiment, the breather assembly includes an input chamber for receiving blow-by gas, the input chamber bounded at least partially by a crankcase exterior, and a standpipe situated inside the input chamber for directing blow-by gas into the input chamber. Additionally, the breather assembly can include an input drainback passage situated inside the input chamber and an output chamber situated adjacent the input chamber, the chamber having an inner wall with a one-way valve that allows blow-by gas to flow from the input chamber to the output chamber. The breather assembly can also include an output drainback aperture situated in the inner wall and an output chamber housing that substantially encloses the output chamber and includes an exhaust port for exhausting blow-by gas.

Breather assembly with standpipe for an internal combustion engine

A common engine speed control mechanism for small internal combustion engines, which may be configured to allow for actuation of the speed control mechanism between stop, idle, and various engine running speed positions by actuation of one of a selected plurality of speed control levers. Each of the plurality of speed control levers is oriented so that it is movable in a direction which is substantially non-parallel to the direction of movement of the other speed control levers. In one embodiment, the actuation of the common speed control mechanism can be accomplished by movement of a first speed control lever in a substantially horizontal, side-to-side direction or by movement of a second speed control lever in a substantially vertical, up-and-down direction.
