With the increasingly reduction of oil equal energy source, oil consumption receives more and more attention in engine art, various countries for this
Fuel economy regulation is increasingly strict, past 10 years, discharges from Ou Si liftings to Europe six, oil consumption requirement have dropped 20%.
Whether the oil consumption of engine and the air inlet of engine are unobstructed closely related, and diesel engines at present has begun to install EGR additional
System, most of recyclable waste gas return to air-inlet grille heating, but when engine operates for a long time, engine charge grid
On can accumulate substantial amounts of greasy dirt, can cause that engine charge is not smooth, and hydraulic performance decline, oil consumption is increased.
Utility model content
The purpose of this utility model is to provide a kind of air inlet joint pipe for diesel engine have compact-sized, in light weight and drop
The characteristics of low engine consumption, to solve above mentioned problem existing for prior art engine.
To use following technical scheme up to this purpose, the utility model：
A kind of air inlet joint pipe for diesel engine, it includes body, wherein, the inlet end of the body is provided with inlet air heating grid
Installation portion, outlet side are provided with oil rule conduit installation portion, if the outer end of the inlet air heating grid installation portion is arranged at intervals with
Dry electronic throttle installation portion, and EGR exhaust connecting tube installation portion is provided with the middle part of the body, on each installation portion
Offer mounting hole.
Especially, the electronic throttle installation portion is provided with three, and three electronic throttle installation portions are in same circumference
It is upper uniform, and offer an electronic throttle mounting hole on each electronic throttle installation portion.
Especially, the first circle for housing inlet air heating grid is offered in the middle part of the inlet air heating grid installation portion
Shape passage, and two inlet air heating grid mounting holes are offered on the inlet air heating grid installation portion.
Especially, offered in the middle part of the EGR exhaust connecting tube installation portion for house EGR exhaust connecting tube second
Circular channel, two EGR exhausts for being located at the second circular channel both sides are offered on the EGR exhaust connecting tube installation portion
Connecting tube mounting hole.
Especially, the oil rule conduit installation portion offers an oil rule conduit mounting hole.
Especially, the outlet side of the body is provided with the V-type clamping module for fixing its body.
