Embodiment
Below with reference to drawings and Examples, the technological scheme of the adiabatic gas exhaust manifold of the utility model is described in further detail.
Refer to shown in Fig. 1 to Fig. 3, the adiabatic gas exhaust manifold of the utility model comprises stainless steel cast air flue 3, be arranged on the suction flange 1 of stainless steel cast air flue 3 imports, be arranged on the outlet(discharge) flange 5 of stainless steel cast air flue 3 outlets, and punching type thermal-protective coating 4, punching type thermal-protective coating 4 forms an enclosed construction with suction flange 1, outlet(discharge) flange 5, and stainless steel cast air flue 3 is enclosed in enclosed construction, has vacuum layer joint 2 on punching type thermal-protective coating.Between punching type thermal-protective coating 4 and stainless steel cast air flue 3, by welding, form sealing every dead level.
Punching type thermal-protective coating 4 is welded by two and half shell thermal-protective coatings, and two and half shell thermal-protective coatings are to adopt stainless steel to be stamped to form.
The adiabatic gas exhaust manifold of the utility model application principle in practice as shown in Figure 4, whole intake and exhaust system comprises: vacuum tank 8, cooler 11, vacuum line 12, turnover water pipe 13, intake manifold 14, closure 6, engine cylinder cover 7, ternary catalyzing unit or turbosupercharger 9, one-way valve 10, and gas exhaust manifold of the present utility model.Wherein, the suction flange 1 of adiabatic gas exhaust manifold of the present utility model is connected with engine cylinder cover 7, and outlet(discharge) flange 5 is connected with ternary catalyzing unit or turbosupercharger 9, and vacuum layer joint 2 is connected with cooler 11 by one-way valve 10.
When engine cold-start or low speed operation at part load, throttle body 6 apertures are less, and vacuum tank 8 utilizes one-way valve 10 performance characteristic, extract intake manifold 14 internal pressures, and store vacuum; Cooler 11 utilizes circulating water of engine to carry out the interior gas of cooling vacuum pipeline 12, the adiabatic gas exhaust manifold of the utility model seals every dead level internal pressure under one-way valve 10 effects, through cooler 11, enter vacuum tank 8, thereby acquisition degree of vacuum, now in the adiabatic gas exhaust manifold of the utility model, exhaust gas temperature is almost difficult to and ambient air generation heat exchange, has played the effect of insulation; Ternary catalyzing unit or turbosupercharger 9 now can farthest utilize high-temperature gas energy to carry out work, thereby reach desirable ignition speed, and realize higher slow-speed of revolution performance by changeable air valve or Matching of Turbocharger.
In like manner, when the high rotating speed full throttle operation of motor, the interior negative pressure of intake manifold 14 is little, and now vacuum tank 8 utilizes the vacuum pressure storing, and in above-mentioned same principle, carries out work.
Sealing of the present utility model farthest makes the temperature in outlet pipe not be passed to the external world every dead level structure, and by turbosupercharger, utilized or produce stronger exhaust resonance etc., no matter which kind of can improve Engine torque in conjunction with effective system matches, particularly naturally aspirated engine has very large space to exhaust resonance, adopts the utility model to be more conducive to high-temp waste gas rate of evacuation and stronger resonance effect.Outer stainless steel has replaced traditional thermal shield design simultaneously, has saved cost.
It should be noted that the adiabatic gas exhaust manifold of the utility model must be used in conjunction with vacuum-control(led) system, vacuum source can be the pressure after engine air throttle body, can be also the vacuum that mechanical vacuum pump provides; Due to higher delivery temperature, vacuum-control(led) system must adopt water-cooled cooler, therefore needs reasonably optimizing engine-cooling system pipeline etc., but does not change any electronic component simultaneously, and operational feasibility is higher.
Technical scope of the present utility model is not only confined to the content in above-mentioned explanation, those skilled in the art can not depart under the prerequisite of the utility model technological thought, above-described embodiment is carried out to various deformation and modification, and these distortion and revise to work as and belong in scope of the present utility model.
