摘要： A method for providing supplemental internal air cooling to a multi-cylinder internal combustion engine. The method involves deactivating the fuel injector to one cylinder for a predetermined time period or temperature decrease, based upon engine operating conditions, and then reactivating the fuel injector. This results in cool air being pumped through the fuel-deactivated cylinder by the reciprocating action of the piston therein, which air-cools the walls, piston, and head of that cylinder from the inside. In response to a controlling algorithm in an Engine Control Module, various of the engine fuel injectors may be deactivated and then reactivated sequentially to provide distributed cooling over the entire engine. The invention is especially useful for motorcycle engines having two or more cylinders when the motorcycles are used at low or stop-and-go speeds, such as in parades or other ceremonial functions.

摘要： A method for diagnosing an operational state of a variable valve lift (WL) device in an engine, wherein the WL device is capable of operating in two modes of operation. The method includes measuring a rotational speed of an engine crankshaft while the engine is running or cranking, correlating the measured crankshaft speed with an estimated engine cylinder pressure or torque, comparing the estimated engine cylinder pressure or torque with an expected range of engine cylinder pressure or torque values for the two modes of operation for the WL device, determining if the estimated engine cylinder pressure or torque falls within the expected range of engine cylinder pressure or torque values, and activating an alert if the estimated engine cylinder pressure or torque falls outside the expected range of engine cylinder pressure or torque values to provide notification that the WL device is operating in an improper mode of operation.

摘要： An apparatus and method for starting an engine (12) having a starter generator (18) for providing a rotational force to a pulley (20) in order to provide the necessary torque to start an engine. The starter generator also receives a rotational force to the pulley wherein the starter generator generates a current when the pulley receives the rotational force. A valve deactivation system reduces the compression in a cylinder of the engine, thereby reducing the torque required to perform a starting sequence of the engine, either permitting this apparatus to be applied to larger engines, lower ambient temperatures, or some combination thereof.

摘要： A method for diagnosing the operational state of a variable valve lift device (VVL) is provided. The method includes providing a first signal indicative of an estimated position of the VVL, the first signal having a first signal-to-noise ratio; determining that the first signal represents either a first condition indicating that the VVL is operating in one of two modes of operation, a second condition indicating that the VVL is not operating in the two modes of operation, and a third condition where the first signal is not in the first or second conditions; and adjusting a camshaft phase angle when the first signal is in the third condition so that the first signal has a second signal-to-noise ratio, wherein the second signal-to-noise ratio is greater than the first signal-to-noise ratio, whereby the operational state of the VVL is identified as one of the first and second conditions.
