    摘要： A handheld work apparatus has at least one tool which is driven by a combustion engine. A portion of an intake channel of the combustion engine is formed by an elastic connecting piece which has a first section and a second section between which an expansion fold is arranged. The expansion fold has a first side wall and a second side wall arranged downstream of the first side wall. A peripheral wall, which extends in the region of the largest outside diameter (a) of the expansion fold, is arranged in flow direction between the first side wall and the second side wall. The connecting piece has a stop for the expansion fold which prevents a segment of the first side wall adjoining the peripheral wall from bearing against the second side wall.

    摘要： The present invention has an object to provide an internal combustion engine in which abnormal combustion accompanying inflow of oil hardly occurs. For this purpose, in one mode of the present invention, the internal combustion engine includes a plurality of cylinders disposed along a flow of cooling water, and a surge tank having a plurality of air outlet ports connecting to the respective cylinders, wherein the surge tank is formed so that relatively much oil accumulates in a vicinity of an air outlet port connecting to a cylinder which is located at an upstream side of the flow of the cooling water, and accumulation of the oil is relatively small in a vicinity of an air outlet port connecting to a cylinder which is located at a downstream side of the flow of the cooling water.

    摘要： An air duct assembly supplies air from an air cleaner housing to an engine throttle and includes a first duct connected to the air cleaner housing and a second duct connected to the engine air intake. Open ends of the first and second ducts are spaced from one another and the second duct has a flared bell mouth at its open end. The second duct includes a sleeve that defines an attenuation chamber. A flexible bellows overlies the first and second ducts and the sleeve, and extends across the space between the first and second ducts to provide an airtight connection therebetween and flex during relative motion between the air cleaner housing and the engine air intake. A hydrocarbon adsorbing material can be housed within the attenuation chamber.

    摘要： A retention assembly secures a hydrocarbon trap within an air intake path of an internal combustion engine. The hydrocarbon trap is positioned within a first air tube, such as an outlet duct of a clean air filter. A second air tube, such as an inlet portion of a clean air duct assembly, is fitted over a portion of the first air tube to enclose the hydrocarbon trap within the first air tube. A clamp is fitted over both the first and second air tubes. A plurality of radially-extending, circumferentially-spaced protrusions that are formed on an inner surface of the second air tube pass through a respective plurality of apertures formed in the first air tube and, under radial compression exerted by the clamp, engage an outer surface of the hydrocarbon trap, thereby securing the trap within the first air tube.
