    摘要： An air-cooled, reciprocating piston, internal combustion engine has at least two adjacent cylinder barrels with a plurality of cooling ribs lying substantially perpendicular to the longitudinal axes of the barrels on at least part of the periphery thereof. The intake ports of the cylinder heads are located on the cooling air inlet side while the exhaust ports are located on the cooling air outlet side, and an air deflection cover overlies the cylinder barrels on the cooling air outlet side. The cylinder barrels are provided on the cooling air outlet side with cooling ribs lying substantially parallel to the longitudinal axes of the cylinder barrels. The air deflecting cover is of a configuration such that at least some of the cooling air flowing, in the area adjoining the crankcase, around and between adjacent cylinder barrels, is deflected toward these parallel lying ribs, so that essentially the total flow of cooling air supplied may be used to cool the hottest area of a cylinder barrels.

    摘要： A reed type valve is operatively secured on the outer surface of the casing of an engine air filter assembly to supply the exhaust system of an engine with secondary air. The reed valve is fluidly connected to an air induction passage formed interior of the casing of the air filter assembly. A resonance chamber is also formed interior of the casing and communicated through a communication passage with the air induction passage so as to attenuate a relatively low frequency component of exhaust noise transmitted through the reed valve. The air induction passage, resonance chamber and communication passage are formed as follows: ##EQU1## where, S.sub.o (cm.sup.2)=the cross-sectional area of the air induction passageS(cm.sup.2)=the cross-sectional area of the communication passagel(cm)=the length of the communication passageV(cm.sup.3)=the volume of the resonance chamberM=the number of the engine cylinders of the engine.

    摘要： A cylinder head assembly for an internal combustion engine includes lower and upper decks and connecting walls defining a coolant chamber with a plurality of exhaust ports for each cylinder extending through the coolant chamber to the lower deck. A longitudinally extending partial intermediate deck intersects the exhaust port walls and partially defines upper and lower sections of the coolant chamber. Connecting walls enclose portions of the lower section of the chamber intermediate the exhaust ports of adjacent cylinders. Adequate support for cores used in casting the main body of the cylinder head is provided through openings connecting the enclosed portions of the coolant chamber with the remaining lower portions and upper section. At assembly, tubular inserts are installed in these openings to block communication of the enclosed chamber portion with the remaining portions and to direct coolant flow into the enclosed portion from an external supply. The arrangement forces coolant to flow between the adjacent exhaust ports and around the fuel injector tube at each cylinder position before passing to other portions of the coolant chamber.

    摘要翻译： 用于内燃机的气缸盖组件包括下部和上部甲板以及限定具有多个排气口的冷却剂室的连接壁，每个气缸延伸穿过冷却剂室至下部甲板。 纵向延伸的部分中间甲板与排气口壁相交并部分地限定冷却剂室的上部和下部。 连接壁围绕相邻气缸的排气口之间的室的下部的部分。 通过将冷却剂室的封闭部分与其余的下部和上部连接的开口，提供了用于铸造气缸盖主体的芯的足够的支撑。 在组装时，管状插入件安装在这些开口中以阻止封闭腔室部分与其余部分的连通并且将冷却剂流从外部电源引导到封闭部分。 该装置在通过冷却剂室的其它部分之前迫使冷却剂在相邻排气口之间并在每个气缸位置处在燃料喷射管周围流动。
