摘要： A modified rocker assembly having an offset end is designed to be used in engine heads having an obstruction that would not allow a switching rocker arm to be used. The modified rocker assembly is described having an obstructed side and a non-obstructed side. The rocker assembly has an outer structure with a first end, and an inner rocker structure fitting within the outer structure, the inner structure also having a first end. The modified rocker assembly has an axle pivotally connecting the first ends of inner structure to the outer structure, such that the inner structure may rotate within the outer structure around the axle. At least one torsion spring on one side of axle, rotationally biases the inner structure relative to the outer structure. The outer structure, on the obstructed side as it extends from the second end toward the first end, is offset toward the non-obstructed side creating the first offset portion to provide additional clearance on the obstructed side. This design allows the modified rocker arm to fit into an engine head having an obstruction on its obstruction side.

摘要： In a vehicle provided with a power propulsion system of the mild-hybrid type, a BAS unit—including an electric machine connected through a belt transmission to the shaft of an internal combustion engine—is exploited as the only propulsion engine of the vehicle in given operating conditions. The internal combustion engine is provided with a system for variable actuation of the intake valves which is controlled to reduce the pumping losses of the internal combustion engine in the phase in which such engine is in cut-off condition and it is driven by the aforementioned BAS unit. It is also provided for that the system for variable actuation of the intake valves be controlled to temporarily increase the pumping losses of the internal combustion engine in a phase in which it is required to accelerate the switching off of the engine.

摘要： A reference angle detecting device includes a control shaft connected to a controlled object, an electric motor causing the control shaft to rotate via a worm gear mechanism, a stopper disposed on a motion track of a worm wheel, an angle sensor that can detect a rotation angle of the control shaft, and a controller. The stopper includes a spring member which is elastically deformable in an operation direction of the worm wheel. The controller drives the electric motor to operate so that the worm wheel may face the stopper, and stores the rotation angle at a time point when a change rate ω of the rotation angle θ detected by the angle sensor changes to a value less than a predetermined threshold ω1 as a reference angle θ0. Therefore, the reference angle can be detected with high accuracy for control of an angle of the control shaft.

摘要： In a cylinder lubrication system for a two-stroke engine, a plurality of lubricating oil supply openings (78) open out in the inner circumferential surface of the cylinder (42) at a point lower than a top ring (22b) of a piston (22) located at a bottom dead center. The lubricating oil supply openings are configured to provide a larger amount of lubricating oil in the thrust side and anti-thrust side of the cylinder than in a remaining part of the cylinder. Thereby, the consumption of lubricating oil and the emission of undesired substances can be minimized while providing an optimum lubrication of the sliding part between the piston and the cylinder.

摘要： The present engine design can comprise one or more three-cylinder modules. Each module can comprise a left-hand combustion cylinder, a compression cylinder and a right-hand combustion cylinder. In an embodiment, the compression cylinder can function as a supercharger providing compressed air to the two combustion cylinders in order to improve performance and efficiency. Each module can comprise a specialized cylinder head comprising an intake air plenum configured to allow pressurized air to flow from the compression cylinder into each of the combustion cylinders. The flow of this pressurized air can be precisely controlled by valves that control airflow into and out of each of the three cylinders. Variable valve timing and computer controls can determine the exact amount of fuel, if any, which will be injected into the combustion cylinders to deliver high fuel economy while delivering an optimal level of power, horsepower and torque.
