Detailed description of the invention
Below with reference to specific embodiment, novel integrated discharge manifold formula four-cylinder cylinder cap of the present invention is done into one
The elaboration of step, to help those skilled in the art that inventive concept, the technical scheme of the present invention are had more complete, accurate and goed deep into
Understanding.
Embodiment 1
As shown in Figure 1-2, the novel integrated discharge manifold formula four-cylinder cylinder cap of the present embodiment, including having of being arranged side by side
1st cylinder of the 1st aerofluxus aditus laryngis 41, the 2nd cylinder, the 3rd cylinder of the 3rd aerofluxus aditus laryngis 43 and the 4th aerofluxus aditus laryngis 44 of the 2nd aerofluxus aditus laryngis 42
The 4th cylinder.It is integrated with in described cylinder cap and is connected to the 1st discharge manifold of described 1st aerofluxus aditus laryngis, be connected to described 2nd aerofluxus
2nd discharge manifold of aditus laryngis, it is connected to the 3rd discharge manifold of described 3rd aerofluxus aditus laryngis and is connected to described 4th aerofluxus aditus laryngis
4th discharge manifold；And the outlet of described 1st discharge manifold, the 2nd discharge manifold, the 3rd discharge manifold and the 4th discharge manifold is equal
Meeting at air exit 2, the position of described air exit 2 is less than described aerofluxus aditus laryngis；It is provided with between adjacent exhaust menifold
Cooling jacket 5.The flange face of described air exit is positioned in the middle of the 2nd cylinder and the 3rd cylinder.At the 1st, 3 cylinder working stroke or the 2nd, 4 cylinder
During working stroke, engine exhaust, after the guiding of this discharge manifold, converges at air exit 2, and two sidewinds are parallel
Trend discharges cylinder cap.Exhaust airstream guides schematic diagram as shown in Figure 3.At air vent flange face, cylinder head studs 3 is installed
Connect catalyst converter.
The structure of the present embodiment can be prevented effectively from the aerofluxus of interval igniting two cylinders and liquidate phenomenon, thus avoids producing aerofluxus and do
Disturb, improve smooth in exhaust degree；Maximized extending exhaust manifold path in cylinder cap, cool time is longer, cooling effect
Become apparent from；Compared to independent exhaustion manifold, by integrated exhaust manifold in head exhaust side, save independent exhaustion system
Exploitation, production and later maintenance cost, evaded the risk of exhaust manifold maintenance, replacing；Cooled down by coolant, from row
Gas manifold EGT out, pressure are substantially reduced, thus reduce the portions such as the ternary catalyzing unit that is connected with exhaust manifold
The thermal stress of part and thermal strain；Vibration and heat exhaustion problem can be prevented effectively from, increase gas extraction system reliability and NVH performance；Add
Fast cold start-up warming-up speed, promotion thermal cycle, thus the discharge of CO and CH in waste gas when reducing cold start-up；Can effectively save aerofluxus
Side arrangement space, system structure is compacter.
In order to alleviate weight and save oil gas, four-cylinder cylinder cap described in the present invention use aluminium alloy casting and
Become.The most described aluminium alloy has good elevated temperature strength, corrosion resistance at a temperature of electromotor uses, and has good
Good casting character is to ensure to need have enough mobility in the molten state；And the alumite used in prior art closes
Gold, for ensureing its elevated temperature strength, generally its Si content is up to 18～25wt%, and the highest Si content causes its Castability to become
Difference, thus complex forming technology, cost is high.The most described aluminium alloy by percentage to the quality, containing 8.2～
The Cu of the Cr of the Ni of the Si of 10.0wt%, 0.8～1.2wt%, 0.5～1.2wt%, 0.2～0.8wt%, 0.3～0.5wt%
The Ca of the Be of Mn, 0.2～0.5wt%, 0.03～0.06wt%, surplus is Al and inevitable impurity；And Fe <
0.1wt%.In the present invention, described V6 type cylinder head pouring temperature is 780～830 DEG C；Carry out at T6 heat after casting
Reason (520 DEG C of solution treatment 8～10 hours, 200 DEG C of Ageing Treatment 10～12 hours after shrend).In the present invention, although
The content of Si is relatively low, but by adding the content of appropriate Cr, Be and Ca, and control the content of Fe less than 0.1wt%, it is possible to protect
Card room temperature strength reaches 280～350MPa, and intensity may also reach up 200～230MPa under conditions of 300 DEG C.
For the ordinary skill in the art, the present invention is simply exemplarily described by specific embodiment,
Obviously the present invention implements and is not subject to the restrictions described above, as long as the method design that have employed the present invention is entered with technical scheme
The improvement of various unsubstantialities of row, or the most improved design by the present invention and technical scheme directly apply to other occasion
, all within protection scope of the present invention.
