Abstract: An engine cover for covering an engine including: a cover body configured to cover the engine from above; and at least one fixing part projecting from the cover body toward an engine side and being configured to be attached to the engine side, wherein the cover body and the fixing part are integrally formed of an urethane foam, and the fixing part has an infirm portion formed at a periphery thereof so that the fixing part is configured to be deformed toward a specific direction due to the infirm portion upon input of a load to the cover body.

Abstract: The present invention provides an engine cover that can be manufactured easily and at a lower cost and has an attachment member that is high in quality and may not easily fall off. The engine cover has a cover body made of urethane foam, a skin layer disposed on a surface of the cover body, and an attachment member made of an elastic body and integrally molded with the cover body. The attachment member has a recess into which an attachment pin provided to project from an engine member is fitted, and a sealing portion that is provided to project at least one of the opening end surface of the recess and the side surface of the opening end part of the recess and that suppresses entry of a foamed urethane resin material that forms the cover body into the recess during integral molding.

Abstract: In a charge forming apparatus comprising fuel supply means including an idling orifice and a low speed orifice for feeding the amount of fuel required during the period that an engine is idling or running at a low r.p.m. and a supplemental fuel passage for guiding the fuel to such orifices and an air feeding bypass for keeping the engine idling, the supplemental fuel passage is connected to a portion of the bypass upstream of a manually operable valve for regulating the flow rate of air by means of a connecting path. A negative pressure generated on the engine side rather than on a throttle valve makes negative the supplemental fuel passage and the bypass, but a negative pressure on the upstream side of a valve of the bypass varies in correspondence with the effective path area varied by the valve.
