Embodiment Construction

[0025] As shown in the figure: the general-purpose gasoline engine of the present invention includes a general machine casing 1 and a two-way engine cylinder head 2 connected with the general machine casing 1, and an upper air passage assembly that forms an upper cooling air passage at the periphery of the general machine cylinder head 2, so The upper air duct assembly includes a fan cover 3 and a shroud, and the shroud and the fan shroud 3 are plugged together to form a cooling air duct through which cooling air flows between the cylinder heads 2 of the two-way machine; the present invention The structure is suitable for forced air-cooled fans, wherein the fan cover 3 is used to cover the impeller, and the fan cover 3 and the wind guide cover assembly are used to form an upper cooling air passage for cooling the cylinder head 2 of the fan. In this embodiment, The plug-in cooperation between the shroud and the fan cover 3 makes the cooperation between the various parts more clo...

Abstract

The invention discloses a general gasoline engine, which comprises a general gasoline engine box body, two general gasoline engine cylinder heads and an upper air passage assembly, wherein the two general gasoline engine cylinder heads are connected with the general gasoline engine box body, the upper air passage assembly surrounds the outside of the general gasoline engine cylinder heads, and comprises a fan cover and a flow guide cover, and the flow guide cover and the fan cover are matched in an inserting connection mode and are used for forming a cooling air passage through which cooling air flows between the two general gasoline engine cylinder heads. Through the inserting and connecting type matching between the flow guide cover and the fan cover, the matching among all components is tighter, the sealing performance of the cooling space is improved, the airflow loss in the cooling space is reduced to the greatest degree, the heat radiation effect is ensured, and the integral structure is compact; in addition, the realization of the structure is simple, the operation is convenient, the dismounting, the mounting and the maintenance are easy, and the replacement is easy.

Description

technical field [0001] The invention relates to the field of general gasoline engine cooling, in particular to a general gasoline engine. Background technique [0002] The cooling air passage of the traditional general-purpose gasoline engine forced air cooling system is usually composed of heat sinks of the box body and cylinder head, fan cover parts and more air guide covers. The fan cover and air guide cover are made of injection molding or metal Manufactured by stamping technology, and connected with the box body or cylinder head by bolts. The formation process of the cooling air flow is: under the action of the impeller, the air is continuously gathered into a certain space formed by the fan cover part, the box body, and the cylinder head, so that the space The pressure increases, and under the action of pressure, the air will flow along the reserved channel connected to this space, that is, the air duct composed of the air guide cover, the box body and the cylinder hea...
