Description

Thrust used for diesel engine positions air inlet pipe
Technical field
The utility model belongs to diesel engine accessory technical field, fixed more particularly to a kind of thrust used for diesel engine Position air inlet pipe.
Background technology
In order to improve engine power, reduce fuel consumption, reduction disposal of pollutants, existing diesel engine largely uses Charge inter cooling technology.Charge inter cooling technology is one of the cooling program entered to supercharging hot-air before cylinder, the increasing after being cooled After pressing the hot-air outflow left gas chamber of charge air cooler, intercooler air outlet pipe is flowed through, into engine air inlet tube, reaches engine charge discrimination Pipe.The engine air inlet tube used when being connected between intercooler air outlet pipe and motor intake manifold at present is all made of common curved Pipe grafting is realized, but engine air inlet tube two-port is being connect installation with intercooler air outlet pipe and motor intake manifold respectively When, fitting depth, setting angle and direction cannot be controlled, appearance consistency is poor after leading to gas leakage and assembly, junction also very Be easy to fall off, the requirement of downstream client cannot be met, under the influence of tourist family efficiency of assembling.
Invention content
The utility model for solve technical problem present in known technology provide it is a kind of it is reasonable in design, can be effective Fitting depth, setting angle and the direction for controlling the pipeline being attached thereto, avoid the thrust used for diesel engine of gas leakage from being positioned into Tracheae, appearance consistency is good after assembly, disclosure satisfy that the requirement of downstream client, improves the efficiency of assembling of downstream client.
The utility model is adopted the technical scheme that solve technical problem present in known technology:
A kind of thrust positioning air inlet pipe used for diesel engine, including air inlet tube body, the both ends point of the air inlet tube body Not Wei air inlet port and air outlet, the air inlet port is connected to intercooler air outlet pipe, the air outlet and inlet manifold Connection, has end flange, on the air inlet pipe body outer wall at air inlet port 35-45mm in the end set of air outlet One circular orientation flange is set, a convex rib one vertical with locating flange, the protrusion are set on the locating flange The thickness of muscle one is consistent with the radial width of locating flange, the end flange and arc transition at the dog-ear of air inlet tube body, Three convex ribs two vertical with end flange are set on arc-shaped transitional surface, and the interval angles between three convex ribs two are successively For 90 ° and 45 °, the convex rib one and three convex ribs two are close to the outer wall of air inlet tube body, the convex rib one and three A convex rib two is respectively positioned on the same side of air inlet tube body.
The utility model can also use following technical measures:
The locating flange, convex rib one and three convex ribs two are integrally formed with air inlet tube body.
The locating flange is arranged on the air inlet pipe body outer wall at air inlet port 40mm.
The material of the air inlet pipe is cast aluminium material.
The utility model has the advantages and positive effects of:
The utility model due to the adoption of the above technical scheme, that is, uses conventional gas introduction at a certain distance from away from air inlet port Locating flange is set on pipe, and a convex rib one normal thereto is set on locating flange, is effectively ensured and is attached thereto Axially mounted length, angle and the direction of intercooler air outlet pipe make sebific duct assembly in place;It is rolled in end flange and air inlet tube body Three convex ribs two vertical with end flange are set on the arc-shaped transitional surface at angle, the hair being connect with air outlet is effectively ensured The shaft installation angle of motivation inlet manifold and direction;Appearance consistency is good after air inlet pipe assembly, disclosure satisfy that downstream client's It is required that improving the efficiency of assembling of downstream client so that complete machine presentation quality improves;And integrally formed structure also increase into The reliability of tracheae installation reduces assembly time, enhancing structure stability, improves engine performance stability.
