Description
Technical field
The present invention relates to a kind of horizontal cylinder diesel engine body cooling water-inlet chamber.Belong to the diesel engine cooling system field.
Background technique
The diesel-engine body cooling water-inlet chamber is the important component part of diesel engine cooling system, and it must guarantee on the one hand that at Structural Design Requirement body cooling water chamber structural design layout is simple and convenient; Also require to guarantee on the other hand the cooling water circulation rationally, the vapour locking phenomenon in the good cooling results, minimizing cooling water, its reasonable in design has directly influenced power character, Economy, reliability and the emission performance index of diesel engine.Chinese patent CN200720104721.2 has proposed a kind of single-double-cylinder horizontal diesel and has forced cooling structure, it adopts and forces cooling structure, improve single cylinder and double-cylinder horizontal diesel cooling effect greatly, but cooling water-inlet chamber is arranged on the upper front end of single-double-cylinder horizontal diesel body, be on the cooling water channel, occur the vapour locking phenomenon in the using process sometimes, reduced cooling effect.
Summary of the invention
Purpose of the present invention is overcoming the shortcoming of prior art, invent and a kind ofly be provided with special cooling water-inlet chamber at horizontal cylinder diesel engine body downside internal body, allow between cooling water-inlet chamber and the cylinder cooling jacket connecting passage the shortest, and prevent to avoid the influence of vapour locking from structure, further increase the pressure cooling water-inlet chamber of the horizontal cylinder diesel engine of cooling effectiveness cooling procedure.
Technical solution of the present invention is: 1, by connecting passage, body cooling jacket, cylinder head cooling water cover, thermostat, the water tank of water pump, cooling water-inlet chamber, cooling water-inlet chamber and cylinder cooling water inner room, be connected the horizontal cylinder diesel engine that water pipe and various cooling water connecting passage form and force cooling water-inlet chamber, it is characterized in that: horizontal cylinder diesel engine body downside internal body is provided with special cooling water-inlet chamber, cooling water-inlet chamber is communicated with by cooling water passage between cooling water-inlet chamber and the cylinder cooling jacket 803 between oil sump attachment face 603 and cylinder cooling jacket.
Be provided with the cooling water-inlet chamber blasthole in body gear chamber attachment face one side, be provided with the husky hole of getting that makes things convenient for the cooling water-inlet chamber casting in body master oil sealing attachment face one side.
In the design of body right flank or left surface (being body gear chamber attachment face one side) water pump attachment face 403 and cooling water blasthole 404 are arranged, in the body left side or right flank (promptly main oil sealing attachment face one side) design the husky hole 302 of getting that makes things convenient for the cooling water-inlet chamber casting is arranged.
Working principle: cooling water enters cooling water-inlet chamber by water pump pressurization back from the cooling water blasthole, enter cylinder cooling jacket respectively by cooling water passage, because cooling water-inlet chamber is located at the body lower end, cold water always flows into cylinder cooling jacket from the bottom up, thereby prevented " vapour locking " phenomenon, strengthened cooling effect.
Its reasonable in design has directly influenced power character, Economy, reliability and the emission performance index of diesel engine.
Be connected by distinctive cooling water passage between cooling water-inlet chamber and the cylinder cooling jacket.
The present invention will be owing to will will force cooling water-inlet chamber design position between body lower end oil sump attachment face and cylinder cooling jacket dexterously, shortened the connecting passage distance, help the circulation of cooling water, it has compact structure, good cooling results, the advantage of no vapour locking is a kind of horizontal single-double cylinder diesel cooling water-inlet chamber of new structure.
