Abstract
The utility model discloses a structure of an intake manifold of a gasoline engine and aims to prevent freezing. A sealing ring is connected to an engine intake manifold and a throttle body, a mesh structure is added to the sealing ring, the mesh structure and the sealing ring are integrated to form a sealing filter screen, and a sheet-like structure is arranged at the outer edge of the sealing filter screen. The structure of the intake manifold of the gasoline engine is mainly used for preventing freezing, simple in structure and low in cost, and the intake manifold cannot rotate during installation.
Description
Technical field
The utility model relates to a kind of engine intake manifold, especially relates to a kind of gasoline engine inlet-air manifold structure.
Background technique
The cold snap such as snow sky, sleet that is lower than 0 degree centigrade at temperature descends; Motor is under low temperature underrun operating mode; Surface pressure is very low behind the throttle body, and throttle valve body control valve back steam temperature can sharply reduce, and is easy to freeze at throttle body control throttle valve rear surface like this.Freezing gets into the firing chamber from throttle valve body, can cause a series of problems such as oil dilution, Mao Baiyan, scuffing of cylinder bore, shake, influence the performance of motor, even can cause motor to cause serious damage the most seriously the time.
Chinese patent notice of authorization number: CN201615002U on October 27 2010 notice of authorization day, discloses a kind of novel high-order suction tude; It is provided with one curved import a section of high-order suction tude body; Be provided with the coarse filtration net to inlet curved, also be provided with stiffening rib on the body, solved the problem of recent noise; But it can not solve cold day, freezes to get into the problem of suction tude.
The model utility content
The utility model is the deficiency that can put ice cube for the gasoline engine inlet-air manifold that overcomes existing technology when the low temperature into, provides a kind of and can block icing a kind of gasoline engine inlet-air manifold structure.
To achieve these goals, the utility model adopts following technological scheme:
A kind of gasoline engine inlet-air manifold structure of the utility model is connected with seal ring at engine intake manifold and throttle body, on seal ring, has increased reticular structure, and this structure and seal ring one are the sealing filter screen.Can well blocking like this freezes gets into intake manifold, has avoided the icing back of gas handling system to get into the engine interior probability, has promoted the unfailing performance when motor moves under severe operating mode.
As preferably, said sealing filter screen outer is provided with a sheet structure.Said sheet structure can prevent to seal filter screen and rotate in installation process, simple in structure.
As preferably, said sealing filter screen is half net and is lower half portion.Because of freezing in air because of quality is positioned at lower half portion greatly, can stop icingly so half net only need be set, provide cost savings.
As preferably, the net bar that constitutes the sealing filter screen is cylindrical.Surface and ice cube that the net bar is moist can stick together, so the net bar of said sealing filter screen is cylindrically can well reduce area of contact, the minimizing adhesion.
As preferably, said sheet structure is located near suction tude outer rim one side.Can save the material of using of this sheet structure like this, save cost.
Therefore, the utlity model has following beneficial effect: (1) is blocked icing; Do not rotate when (2) installing; (3) cost is lower.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the assembling schematic representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further description.
In Fig. 1, embodiment shown in Figure 2; Be connected with seal ring 1 at engine intake manifold and throttle body; On seal ring 1, increased reticular structure; This structure and seal ring 1 one are sealing filter screen 2, have so just reduced the impaired possibility of motor greatly, and sealing filter screen 2 outers are provided with a sheet structure 3.As shown in Figure 2, sheet structure 3 is located near intake manifold outer rim one side, and this sheet structure slightly exceeds attachment face when mounted, exceeds to have reached spacing effect after part bends, and does not rotate when making it to install.As shown in Figure 1, sealing filter screen 2 is half net and is lower half portion that the net bar that constitutes sealing filter screen 2 is cylindrical.Thus, sealing filter screen 2 just can stop freeze and to air-flow pass through do not impact, can be because of moist surface and icing adhesion do not result in blockage, the net bar that has reduced area of contact influences several nothings of ventilatory effect of sealing filter screen.
Motor is under low temperature underrun operating mode, and the closure place generally is the very large element of the pressure loss because throttle valve plate in the ordinary course of things many places in the little state of aperture, so the pressure loss is big.When behind throttle body, when pressure sharply descended, in the intake manifold outer end that enters the mouth, prevent to freeze got into cylinder to sealing filter screen 2, influences engine performance with the icing retaining of throttle valve rear surface.
Claims (5)
1. a gasoline engine inlet-air manifold structure is connected with seal ring at engine intake manifold and throttle body, it is characterized in that, on seal ring, has increased reticular structure, and this structure and seal ring one are the sealing filter screen.
2. a kind of gasoline engine inlet-air manifold structure according to claim 1 is characterized in that, said sealing filter screen outer is provided with a sheet structure.
