    Abstract: A priming system for an engine system having a throttle valve configured to regulate a flow of air and fuel into an intake manifold of an engine is disclosed. The priming system may include a first sensor configured to generate a first sensor signal indicative of a value of an engine parameter, an auxiliary fuel line configured to direct fuel from a fuel source to a primed cylinder subset of the plurality of cylinders, an auxiliary fuel valve disposed in the auxiliary fuel line, and a controller in communication with the first sensor and the auxiliary fuel valve. The controller may be configured determine the value of the engine parameter from the first sensor signal and cease directing fuel from the auxiliary fuel line to the primed cylinder subset when the engine parameter value is greater than or equal to a threshold engine parameter value.

    Abstract: An air flow velocity calculating device of a internal combustion engine, has a cylinder, a spark plug, an air intake passage, an air flow controlling valve, an air flow velocity calculating portion, and an electric discharge current controlling portion. An electric discharge between a center electrode and a ground electrode is sustained during an electric discharge sustaining period. The electric discharge sustaining period is a period from when the electric discharge begins to when the electric discharge is intercepted by the air flow. Energy is supplied to the spark plug, so that the electric discharge current is sustained at a constant value by the electric discharge current controlling portion during an ignition period. The ignition period is a sum of an electric discharge sustaining period of a first electric discharge and electric discharge sustaining periods of second and subsequent electric discharges in one cycle of the internal combustion engine

    Abstract: An intake apparatus and methods of an internal combustion engine that controls an intake air current to the combustion engine. An intake current control valve has an open portion for passing intake currents, and has an external shape that has at least four corner portions corresponding to a shape of an intake pipe. Precise control of the amount of intake air can be accomplished if the open portion is closed, and then the amount of air leaking via the periphery of the valve is measured.

    Abstract: A butterfly bypass valve includes a housing defining a bypass flow passage with a pivotable throttle plate therein. An outer edge of the throttle plate in a closed position is in sealing engagement with a sealing portion of the housing such that the throttle plate restricts fluid flow through the bypass flow passage. The throttle plate is pivotable to an open position to allow fluid flow through the bypass flow passage. A port in the housing allows a portion of fluid passing through the bypass flow passage to be removed when the throttle plate is pivoted to the open position. A predetermined amount of pivoting of the throttle plate toward the open position can occur so as to allow flow through the port, while maintaining the edge of the throttle plate in substantially sealing engagement with the sealing portion so as to substantially prevent flow through the bypass passage.
