Description
Technical field
The present invention relates to a kind of motor car engine annex, specifically, relate to a kind of automobile engine intaking and discharging apparatus.
Background technique
The intake and exhaust device of existing motor car engine mainly is made up of air inlet system and venting gas appliance, wherein air inlet system is made up of resonant cavity and the intake manifold that is attached thereto, air enters each cylinder respectively by resonant cavity and each intake manifold, venting gas appliance is made up of the gas exhaust manifold and the exhaust manifold that are connected with each cylinder, and the waste gas of each cylinder is aggregated into exhaust manifold by gas exhaust manifold and discharges.There is the length difference of intake manifold in existing intake and exhaust device, can cause the inflation effect of each cylinder to differ, because existing electronic fuel injection engine is to control oil spout and burning according to the inflation effect of each cylinder, the inflation inequality will inevitably cause each cylinder operation load inhomogeneous, engine roughness, the individual cylinder excessive wear that can cause in the course of time, and the noise of intake and exhaust is big, and the intake and exhaust mechanism action is insensitive.In addition, also exist the sectional shape and the rational inadequately problem of location arrangements of suction tude, can cause the on-way resistance of air inlet-outlet pipe bigger, influence the charging efficiency of motor, especially the most obvious to the charging efficiency influence of motor when high speed and the Maximum Torque operating mode, because require the highest to the charging efficiency of motor this moment.
Summary of the invention
The present invention's technological scheme required for protection provides a kind of to each cylinder charge equilibrium, realizes not having the machinery concussion, the automobile engine intaking and discharging apparatus that charging efficiency is high.
The present invention's technological scheme required for protection is as follows:
Automobile engine intaking and discharging apparatus, comprise housing, housing is provided with induction part and discharge portion, induction part is made up of resonant cavity and intake manifold, each intake manifold is connecting resonant cavity and each cylinder air inlet respectively, the cross section of the inner chamber of intake manifold is circular, discharge portion is that single outlet pipe directly is fitted on the cylinder exhaust port, described each intake manifold is the circular arc of equal in length, and arrange on resonant cavity equal intervals ground, the sectional shape of resonant cavity is: a side of arranging intake manifold is a rectangle, opposite side is a circular arc, and round valve is installed in the described housing, and the round valve two ends are provided with left Seal cage and right Seal cage respectively.Described round valve is installed on the axle, and drive wheel is installed on the axle, and the external diameter of round valve is coniform, offers left chamber and right chamber on the round valve.
The present invention's technological scheme required for protection compared with prior art has obvious improvement: (1) has improved the inflation harmony of cylinder.The present invention adopts the intake manifold of equal in length, guarantees that on-way resistance is all identical for each cylinder, makes each cylinder charge even, each cylinder operation load balancing, engine mildness.(2) realize not having the machinery concussion, technological scheme of the present invention is installed round valve in housing, and the round valve two ends are provided with left Seal cage and right Seal cage respectively.Effectively eliminated mechanical concussion.(3) improved charging efficiency.Technological scheme of the present invention has been done improvement on the sectional shape of intake manifold and profile, intake manifold adopts the orthodrome transition between resonant cavity and cylinder, intracavity section adopts circular, reduced on-way resistance, improve charging efficiency, satisfied the inflation requirement of motor when high speed and Maximum Torque operating mode.(4) length of intake manifold and outlet pipe has been made optimal design, has improved charging efficiency and coefficient of scavenging, makes air inlet more abundant, and exhaust is more thorough.(5) design of outlet pipe is fit to and three-element catalytic emission-control equipment coupling, meets the environment protection emission requirement more.

Embodiment
Automobile engine intaking and discharging apparatus comprises that housing, housing are provided with induction part and discharge portion, induction part is made up of resonant cavity 1 and intake manifold 2, each intake manifold 2 is connecting resonant cavity 1 and each cylinder respectively, the equal in length of each intake manifold, and arrange on resonant cavity equal intervals ground, manifold 2 total measurement (volume)s are 0.755L, and length of run is 440mm, and the cross section of the inner chamber of intake manifold is circular.Adopting the intake manifold of equal in length is in order to guarantee that on-way resistance is all identical for each cylinder, to make each cylinder charge good uniformity, each cylinder operation load balancing, engine mildness.The intracavity section of intake manifold 2 adopts circular, is because circular cross-section is more smooth, under identical surface area, the sectional area maximum of circular cross-section, can farthest reduce on-way resistance like this, improve charging efficiency, for the output power and the output torque that improve motor have been created condition.Each intake manifold 2 adopts arc transition between resonant cavity 1 and cylinder, be in order to reduce on-way resistance equally.
The cross section of resonant cavity 1 is a steamed bun shape---a side of promptly arranging intake manifold 2 is a rectangle, and opposite side is a circular arc.On the one hand being in order to obtain big as far as possible volume, is for the ease of being connected with intake manifold 2 on the other hand, and satisfies the requirement on casting.
Resonant cavity 1 is 1.0 with the ratio of displacement, has both guaranteed that resonant cavity had the volume that can satisfy need of work, takies less space simultaneously as far as possible.
The valve overlap phase that has an inlet and exhaust valve all to open in the port timing of existing motor, waste gas in the outlet pipe may flow backwards at this moment, enter cylinder, make oxygen content decline in the cylinder, cause engine power to descend, therefore the length of the length of designing requirement intake manifold and outlet pipe is complementary with the pulsation number of times of intake and exhaust pressure wave respectively, and the long more easy more coupling requirement that reaches of outlet pipe length.But then, the three-element catalytic waste gas treatment process requires exhaust gas temperature high more good more; Simultaneously, the exhaust gas temperature height also helps installing pressurized machine to improve intake efficiency, improves the power of motor, and this just requires outlet pipe length short more good more.For solving above-mentioned contradiction, the present invention has made optimal design to the length of intake manifold and the length of outlet pipe, and the length ratio that makes the length of intake manifold and outlet pipe is 2.5, makes that air inlet is more abundant, exhaust is more thorough.
