Description
Technical field
The utility model relates to diesel engine air inlet system and exhaust system technical field, particularly a kind of diesel engine machine multifunctional intake manifold.
Background technique
For meeting the demand of the automatically controlled demarcation of electric-control motor and different client's car load coupling, need monitor engines in real time suction pressure and temperature to control suitable air fuel ratio; Air compressor needs supercharging to get gas to provide the pressurized air of OEM car load abundance simultaneously; Also need during low-temperature cool starting to provide ether assisted cold start to spray interface, adopt the engine demand of EGR (gas recirculation system) bleed strategy to possess waste gas introducting interface in addition.Current intake manifold's function ratio is more single, be only motor provide cold in compression after air, need to design multiple part and could meet different customer demand, design cost and mould development cost is high, poor compatibility, and difficult arrangement, outward appearance is not compact.
Summary of the invention
The purpose of this utility model provides a kind of diesel engine machine multifunctional intake manifold for the problems referred to above, can meet and monitor engines in real time suction pressure and temperature transducer are installed, also air compressor supercharging can be provided to get the interface of gas, the interface that low-temperature cool starting ether supplies can also be provided, the waste gas introducting interface with EGR (gas recirculation system) can be provided simultaneously.
The technical solution of the utility model is achieved in that a kind of diesel engine machine multifunctional intake manifold of the present utility model comprises body, suction port, air outlet, it is round chamber that suction port is closed in its body inherence, be kidney ellipsoid chamber closing on air outlet, natural transition between round chamber and kidney ellipsoid chamber, a sidewall there are two outside kidney ellipsoid chamber with the bolt hole of screw plug, the same side round chamber outer wall has air compressor to get gas interface, and getting between gas interface at bolt hole and air compressor has temperature and pressure transmitter interface.
Described temperature and pressure transmitter interface comprises temperature and pressure transmitter measuring hole and sensor wire harness mounting hole.
Described suction port is the flanged surface that a symmetrical circle reef knot closes, namely two limits up and down of the housing of flanged surface are straight lines, the right and left is the circular housing of Ф=114mm, and four angles are small round corners of R1=11mm, is the transition of R2=11mm inner circle between circular housing and small round corner.
Air outlet is the flanged surface that interior oval foreign side combines, the long S=197mm of interior oval, end circular diameter D=55mm.
Advantage of the present utility model: the utility model can meet installs monitor engines in real time suction pressure and temperature transducer, also air compressor supercharging can be provided to get the interface of gas, the interface that low-temperature cool starting ether supplies can also be provided, the waste gas introducting interface with EGR (gas recirculation system) can be provided simultaneously.Can realize the different configuration needs of different client, mould compatibility is high, designs and develops cost low.

Embodiment
As Figure 1 and Figure 4: diesel engine machine multifunctional intake manifold of the present utility model comprises body 1, suction port 2, air outlet 3, it is round chamber that suction port 2 one side of something is closed in body 1 inherence, closing on air outlet 3 one side of something for kidney ellipsoid chamber, natural transition between round chamber and kidney ellipsoid chamber, a sidewall there are two outside kidney ellipsoid chamber with the bolt hole 4,5 of screw plug, the same side round chamber outer wall has air compressor to get gas interface 7, and getting between gas interface 7 at bolt hole 4,5 and air compressor has temperature and pressure transmitter interface 6.Described temperature and pressure transmitter interface 6 comprises temperature and pressure transmitter measuring hole 6a and sensor wire harness mounting hole 6b.
Fig. 3 is air inlet side view: described suction port 2 is the suction port flanged surface 2a that a symmetrical circle reef knot closes.Described round reef knot closes and is: two limits up and down in the square frame of long L=114mm are straight lines, and the right and left is the circular housing of Ф=114mm, and four angles are small round corners of R1=11mm, are the transition of R2=11mm inner circle between circular housing and small round corner.The suction port 2 of described intake manifold is the flanged surface that a symmetrical circle reef knot closes, and compare circular flange face, this compact structure also saves material.
Fig. 2 is air outlet side view: air outlet 3 is the air outlet flanged surface 3a that interior oval foreign side combines.The long S=197mm of interior oval, the diameter of a circle D=55mm at two ends, due to the intake method for oval hole, relative to circular port intake method, cylinder cap height can be made significantly to reduce, and structure is compacter.
It is the boss on the body 1 of intake manifold that described air compressor gets gas interface 7, can meet air compressor supercharging and get gas and natural aspiration two kinds of engine configurations demands: when gas is got in air compressor supercharging, boss machining air compressor be got gas interface 7; During air compressor natural aspiration, without the need to machining, retain boss structure.
, there is the boss of a temperature and pressure transmitter interface 6 in neutral position on described body 1, boss provides sensor wire harness mounting hole and temperature and pressure transmitter measuring hole.
Described two bolts hole 4,5 with screw plug, remove any one or remove two screw plugs simultaneously, can install engine low-temperature cold starting ether supply arrangement, also can import EGR (gas recirculation system) waste gas during use; The used time does not retain screw plug on intake manifold.
