    • A moisture absorption apparatus comprises a desiccant container with a side wall and optionally a bottom and a desiccant solution container with a side wall and a bottom. The desiccant container receives particulate desiccant which forms a desiccant solution on contact with moist air. The desiccant container side wall has at least one air access opening and a passage permitting desiccant solution to flow into the desiccant solution container. The desiccant solution container has a top opening and is slidingly displaceable on the desiccant container so as to allow the desiccant container to be displaced in the desiccant solution container to a depth sufficient for the desiccant solution container side wall to fully cover the air access opening of the desiccant container.
    • 吸湿装置包括具有侧壁和任选的底部的干燥剂容器和具有侧壁和底部的干燥剂溶液容器。 干燥剂容器接收与潮湿空气接触形成干燥剂溶液的颗粒状干燥剂。 干燥剂容器侧壁具有至少一个进气口和允许干燥剂溶液流入干燥剂溶液容器的通道。 干燥剂溶液容器具有顶部开口并且可在干燥剂容器上滑动移动,以便使干燥剂容器在干燥剂溶液容器中移动至足以使干燥剂溶液容器侧壁充分覆盖空气通道开口的深度 干燥剂容器。

    • A method and system for controlling combustion engines by detection of the present air/fuel ratio within the cylinders of the combustion engine, using an analysis of the characteristics of the ionization current, as detected via a measuring gap with a bias voltage applied being arranged in the combustion chamber, preferably using the spark plug gap in an Otto-engine. A measuring voltage corresponding to the degree of ionization is detected during the flame ionization phase and during a time- or crankshaft position dependent period A, B, C or D, which duration is dependent of the present air/fuel ratio, and will be finished by an amplitude maximum PF during the flame ionization phase. A parameter characteristic for the fundamental frequency of the measuring voltage during the period A, B, C or D is detected, which parameter indicates a tendency towards the rich direction of stoichiometric when the fundamental frequency increases, and inversely indicates lean tendency when the fundamental frequency decreases. The fundamental frequency is preferably detected from the differential value of the measuring voltage during the period A, B, C or D, in respect of time t or crankshaft degrees VC. dU.sub.ION /dt respectively dU.sub.ION /dVC. The differential value multiplied with a constant is used at least partly when determining a relative or absolute air/fuel ratio.
