    摘要: Device for measuring the rheological properties of a viscoelastic material, formed of an upper rotating plate (10) and of a lower rotating plate (20) which are able to press against the opposite faces of a sample S of the material to be measured. The axes of rotation (a1 a1′ and a2 a2′) of said plates are arranged parallel to one another in a direction perpendicular to the plane formed by the plates, and offset from one another by a distance d. Two independent motors (12, 22) drive respectively the upper plate (10) and the lower plate (20) at the same speed of rotation ω, without giving rise to any angular displacement between the two plates.

    摘要: A method for controlling fueling of an engine, the method comprising during an engine cold start and before the engine is warmed to a predetermined level, transitioning from open-loop fueling to closed-loop fueling, where during closed-loop fueling feedback from an exhaust gas oxygen sensor is utilized and where said closed-loop fueling generates a cycling of delivered fuel in maintaining exhaust air-fuel ratio at a desired level; and providing a fueling adjustment to a subsequent engine start in response to fueling information, said fueling information obtained over at least a complete cycle of closed-loop fueling following said transition from open-loop fueling.
