摘要： A low-pressure-loop EGR apparatus of an engine includes an EGR passage to allow part of exhaust gas discharged from a combustion chamber to return as EGR gas to the combustion chamber, and an EGR valve to regulate a flow of EGR gas in the EGR passage. This passage has an inlet connected to an exhaust passage downstream of a turbine and an outlet connected to an intake passage upstream of a compressor. In the intake passage, an intake bypass passage is provided to connect an upstream portion and a downstream part from the compressor. An ABV is provided in the passage. To remove EGR gas remaining in the ABV, one end of a residual gas removal passage is connected to the intake passage downstream of a throttle valve and the other end of the same passage is connected to the ABV.

摘要： An air induction system for an engine includes an air filter box configured to receive an air filter that separates the air filter box into an atmosphere side and a filtered air side, a clean-air duct coupled downstream from the air filter box and upstream of the engine relative to a direction of air flow during engine operation, a flow-through hydrocarbon trap positioned within the clean-air duct, and a bypass hydrocarbon trap secured within the air filter box on the filtered air side, the hydrocarbon trap having a plurality of generally flat or coiled layers of hydrocarbon adsorbing material sandwiched together and secured one to another. Mechanical fasteners such as grommets may extend through the plurality of layers to secure the layers together. The fasteners may be secured to ribs extending along an upper surface of the air filter box or an interior surface of the clean-air duct.

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： An evaporative fuel adsorbent 32, which adsorbs evaporative fuel, is positioned substantially parallel to a sidewall surface 30 of a surge tank 22. A retention member 34 is positioned between the sidewall surface 22 and evaporative fuel adsorbent 32 to prevent oil, which runs down on the sidewall surface 22, from adhering to the evaporative fuel adsorbent 32. The evaporative fuel adsorbent 32 is mounted on the sidewall surface 30 of the surge tank 22 via the retention member 34.
