Description
Technical field
The present invention relates to the parts of motor car engine, be specifically related to the inlet manifold assembly of motor car engine.
Background technique
Along with the development of automotive industry and the increasingly stringent of environmental regulation, the power character of people to automobile, Economy, discharge etc. require more and more higher.In order to improve the performance of motor car engine, optimize the combustion process of motor, increasing new technology is applied on motor, and variable intake manifold technology is exactly one of this class new technology.Variable intake manifold technology is divided into variable intake manifold technology and variable air inlet mouth cross section technology.Wherein, variable air inlet mouth cross section technology (Port De-Activation, calls PDA in the following text) is to improve combustion efficiency by changing the cross section of suction port, make motor in the time of the slow-speed of revolution more steadily, moment of torsion is more sufficient, more smooth and easy when high rotating speed, power is more powerful.
PDA technology is mainly divided into valve plate-type and slide board type, the at present slide board type PDA technology of domestic and international application, its skateboarding direction be parallel to the outlet of intake manifold air flue arrange put to.Existing employing slide board type inlet manifold assembly as shown in Figure 4, there is the intake manifold 1 of four intake ducts 11 and be arranged on the sled mechanism in intake manifold 1, the air flue outlet end of intake manifold 1 has flange plate 4, sled mechanism comprises slide plate 2 and skateboard control mechanism, in intake manifold 1, offer the chute 12 that connects each air flue, under the effect of skateboard control mechanism, slide plate 2 can slide in the interior edge of chute 12 direction parallel with air flue outlet orientation, in the time that slide plate 2 slides, slide plate is respectively by each air flue exit portion sealing.Described skateboard control mechanism comprises by support 32 and is arranged on the vacuum valve 3 on intake manifold flange dish 4, connecting rod 31 ends at vacuum valve 3 are provided with hinged ball cover 34, on slide plate 2, be provided with hinged ball 33, the connecting rod 31 of vacuum valve 3 is connected with slide plate with hinged ball 33 by hinged ball cover 34, and vacuum valve can drive slide plate to move along the direction parallel with intake manifold air flue outlet orientation.Under low speed operating mode, the outlet of the air flue of intake manifold is blocked a part by slide plate, thereby makes cylinder realize the eccentric air inlet in left and right, and the air inlet cross section of intake manifold reduces, and airspeed increases, and therefore in cylinder, mixed gas produces stronger eddy motion.Under high-speed working condition, vacuum valve is drawing skateboarding, and the air inlet cross section of intake manifold increases, and ensures the air inlet demand of motor.
But, there is following drawback in the inlet manifold assembly of existing employing slide board type: one, each air flue outlet in intake manifold is run through connection by chute, because slide plate adopts vacuum valve traction, when the restriction of its tractive force requires skateboarding, resistance will be accomplished very little, therefore between slide plate and chute, can not realize effective sealing, and then cause motor mutual gas blowby between each cylinder in the running, if situation seriously can further cause the phenomenons such as engine running is bad.Two, skateboarding direction be parallel to intake manifold air flue outlet arrange put to intake manifold owing to only changing the sectional area of air flue outlet at left and right directions (i.e. the direction parallel with air flue outlet orientation), therefore can only realize single eddy motion in cylinder, cannot realize the function of further enhancing to the motion of combination gas in cylinder.
Summary of the invention
The object of this invention is to provide a kind of variable air inlet mouth cross section inlet manifold assembly, to avoid motor at gas blowby mutually between when work each cylinder, make combination gas in cylinder, can produce eddy current simultaneously and can produce and roll stream again.
Variable air inlet mouth of the present invention cross section inlet manifold assembly, comprise and there is the intake manifold of at least two intake ducts and be arranged on the sled mechanism in intake manifold, the air flue outlet end of intake manifold has flange plate, sled mechanism comprises slide plate and skateboard control mechanism, each air flue outlet end in intake manifold all offers the chute connecting with this air flue, slide plate combines as a whole by cross slide with cross slide and the longitudinal slide that equates with chute quantity forms, each longitudinal slide is positioned at each chute and chute is slidably matched, under the effect of skateboard control mechanism, each longitudinal slide can slide along the direction vertical with air flue outlet orientation in chute separately, and when slide plate is when sliding into limit position in intake manifold, each longitudinal slide is respectively by each air flue exit portion sealing.
Described chute is opened in described flange plate side.
Under low speed operating mode, skateboard control mechanism drives slide plate to move along the direction vertical with intake manifold air flue outlet orientation, the air flue outlet that makes intake manifold by longitudinal slide on air flue outlet left and right directions (i.e. the direction parallel with air flue outlet orientation) block a part, combination gas can only export the part not being blocked from air flue and enter cylinder, thereby make cylinder realize the eccentric air inlet in left and right, in cylinder, form eddy current.
Under high-speed working condition, skateboard control mechanism drives slide plate to move outside air flue outlet along the direction vertical with intake manifold air flue outlet orientation, make longitudinal slide exit air flue outlet completely, the air inlet cross section of intake manifold increases, the air inlet cross section that is combination gas increases, and ensures the air inlet demand of motor.
And in the process of slide plate slides, combination gas is not only passed through from a side of the interior longitudinal slide of air flue outlet, form eddy current, but also pass through from the top of the interior longitudinal slide of air flue outlet, and then flow along performance upper wall, form certain stream that rolls.
Variable air inlet mouth of the present invention cross section inlet manifold assembly, because each the air flue outlet end in intake manifold all offers the chute connecting with this air flue, make longitudinal slide in the time sliding, can not cause the gas blowby of each air flue outlet of intake manifold, and then avoided mutual gas blowby between the each cylinder of motor, ensure the good operation of motor; And combination gas can produce strong eddy current while entering in cylinder, can produce again the stream that rolls to a certain degree, strengthen the motion of combination gas in cylinder, make its mixing more even, engine combustion obtains more thorough, has improved the fuel economy of motor.
