The disclosure relates to a method for operating a supercharged internal combustion engine having at least one cylinder group with a number n of combustion chambers, wherein, during a first operating state, all n combustion chambers are supplied with combustion air via a primary charge air path and, during a second operating state, only a portion of the n combustion chambers are supplied with combustion air from the primary charge air path and another portion of the n combustion chambers are supplied with combustion air from a separate compressed air reservoir.

An air-shut off valve for an engine is provided to reduce the number of engine cycles that occur if an engine starts in reverse. The air shut-off valve includes a shaft centered on and extending along a longitudinal axis and a valve plate centered on a central axis. The valve plate is mounted on the shaft and positioned such that the central axis and the longitudinal axis do not intersect with each other. The valve plate can be actuated automatically (i.e., through air interfacing with the valve plate) or manually (i.e., by a user) between an opened position and a closed position with respect to the air intake tube.

An engine includes a plurality of cylinders, a gas chamber, and a heat shielding member. The plurality of cylinders are provided along a crankshaft. The gas chamber extends from a first end portion toward a second end portion in a direction of an axial line of the crankshaft and distributes gas into the plurality of cylinders. The heat shielding member is provided in the gas chamber. The heat shielding member extends from the first end portion toward the second end portion and shields heat radiated from an inner wall surface of the gas chamber.

A vehicle includes an electrical system which has at least one control unit and a first operator input device operably coupled to the at least one control unit. Additionally, the electrical system includes a second operator input device electrically coupled to the at least one control unit. The at least one control unit being operative to power on at least the engine. Also, the electrical system includes a security input device operably coupled to the at least one control unit. The at least one control unit is configured to transmit an actuation signal to the security input device in response to actuation of the first operator input device independent of actuation of the second operator input device and in response to actuation of the second operator input device independent of actuation of the first operator input device.

A throttle apparatus for an engine according to the present invention includes a pair of throttle bodies 2f and 2r disposed between a pair of banks Bf and Br of a V-type engine E, a pair of throttle bores 3 provided in the respective throttle bodies 2f and 2r and configured to guide intake air, throttle valves 5 supported to be openable/closable by a pair of throttle shafts 4 intersecting an arrangement direction of the banks and an axial direction of the throttle bores 3 and parallel to each other, and coupling portions 28 and 23 extending from the respective throttle bodies 2f and 2r in a direction approaching each other and configured to couple the throttle bodies 2f and 2r by being fastened at abutting portions 28b and 23c superimposed on each other with fastening members 30.

A method and system to restrict the flow of accumulated liquid water from the intake manifold into the cylinders of an internal combustion engine by reducing the velocity of contained liquid water as it moves through the containment feature during vehicle maneuvering are disclosed. The body of the intake manifold includes a water containment feature having a water containment reservoir having an open upper portion and water-restricting interior walls. A water passageway is provided in each interior wall. The water passageway may be of any of several shapes, including a V-shape notch extending from the top of the wall. The interior wall is a central interior wall and the containment reservoir further includes an intermediate interior wall between the side walls that intersects the central interior wall. The water passageway is formed in at least one of the interior walls and may be formed in all of the walls.
