Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the noun of locality of use as " upper and lower " normally for direction shown in the drawings or for each parts mutual alignment relationship description word vertically, on vertical or gravitational direction.
The common effect of cylinder head is sealing cylinder, jointly forms combustion space with piston, and bears the effect of high-temperature high-pressure fuel gas.The intake manifold effect of motor is assigned in each cylinder by gas (such as air, fuel mixture are by Carburetor or throttle body), and what produced by gaseous combustion tries hard to recommend dynamic piston movement, to make engine generates power.Wherein, cylinder head has complicated inner chamber, and this inner chamber is formed with a part for water jacket, gas-entered passageway and firing chamber or firing chamber.And the intake manifold of motor is connected to provide flammable or combustion-supporting gas in firing chamber with cylinder head.
Traditional intake manifold is connected with the outer side wall of traditional cylinder head as independent parts, because this increasing weight and the number of components of overall engine, and the utility model provides a kind of cylinder head 1 as shown in Figure 1, intake duct 2 is formed in this cylinder head 1, the outer side wall that the entrance 3 of intake duct 2 is formed in cylinder head 1 can be communicated with suction tude, and the outlet of intake duct 2 is communicated with cylinder.The utility model is by being integrated in the inner chamber of cylinder head 1 using the intake duct 2 as intake manifold, make the weight and the number of components that decrease overall engine, make the level of integration of cylinder head 1 higher simultaneously, reduce fuel consume and the fabricating cost of motor, facilitate the layout of motor on car load, and do not need the sealing that in consideration prior art, intake manifold is connected with cylinder head.Particularly, the entrance 3 of intake duct 2 is formed on the outer side wall of cylinder head 1, can be communicated with suction tude, to carry gas in intake duct 2, and is dispensed in each cylinder by gas by the outlet of the intake duct 2 being integrated into cylinder head 1.
Because the cylinder number of motor is more, crank rotation is more even, vibrates also less, and therefore usual is multicylinder engine (namely having the motor of two or more cylinder) by engine design.Because motor has multiple cylinder, therefore especially, the described outlet of intake duct 2 comprises multiple branch road 4, and one end of branch road 4 is communicated in entrance 3, the other end is communicated with corresponding cylinder, to be imported in corresponding cylinder by branch road 4 by the gas being delivered to entrance 3 by suction tude.
Especially, branch road 4 extends from entrance 3 to the bottom bend of cylinder head 1, to be communicated with corresponding cylinder.Wherein more particularly, the length of each branch road 4 is all equal with tortuosity.Air, fuel mixture or clean air must be assigned to each cylinder by intake duct 2 as intake manifold as far as possible equably, make the combustion position of each cylinder of motor identical, length and the tortuosity of the gas flow in each branch road 4 of therefore intake duct 2 should be equal as much as possible.In addition, in order to reduce gas flow resistance, improve air inlet ability, the inwall of each branch road 4 of intake duct 2 should be smooth.
The gas entered by entrance 3 by intake duct 2 by each branch road 4 of the outlet of intake duct 2 is imported in corresponding cylinder, and especially, the number of branch road 4 is equal with the number of cylinder.In preferred implementation of the present utility model, form 12 branch roads 4 in the inner chamber of cylinder head 1, correspondingly motor has 12 cylinders.
Especially, entrance 3 place of cylinder head 1 is also circumscribed with air inlet bridge piece 5, and air inlet bridge piece 5 is for being connected with suction tude.Because air inlet bridge piece 5 has certain bent angle, make when air is delivered to the entrance 3 of cylinder head 1 by suction tude, bent angle can play the effect of stop portions gas, and air inlet bridge piece 5 can be abated the noise, and that reduces gas flings power.
A kind of motor, this motor comprises cylinder block, and cylinder block comprises multiple cylinder, and motor is provided with cylinder head 1, and wherein, cylinder head 1 sealing is arranged in cylinder block, and multiple branch road 4 is communicated with corresponding cylinder.Multiple cylinder respectively compartment of terrain is formed in cylinder block, and sealed by cylinder head 1, make to form multiple independently combustion space, gas imports in corresponding cylinder by multiple branch roads 4 that intake duct 2 exports, gas in each cylinder is in independently combustion space burning separately, thus produce the power promoting piston movement, make the crank rotation of motor, think that the equipment such as automobile provide power.Simultaneously by arranging the cylinder head 1 being integrated with intake duct 2 on the engine, make motor spatially compacter, reduce number of spare parts and assembling needed time, reduce the cost of motor, improve motor level of integration, reduce the weight of motor simultaneously, thus reduce fuel consume, facilitate the layout of motor on car load.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible compound mode.
In addition, also can carry out combination in any between various different mode of execution of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
