Abstract
The utility model relates to automotive engine component field, particularly relates to a kind of engine intake manifold.The engine intake manifold that a kind of anti-closure freezes, comprise inlet manifold, the bottom surface of described inlet manifold is provided with a suction port, described throttle body is communicated with at suction port, throttler valve is provided with in described throttle body, the height on the interior edge of described bottom surface is higher than the outer of bottom surface, and the interior edge of described bottom surface is that the outer of bottom surface is away from air inlet side near air inlet side.The utility model, by arranging the retaining cavity that is positioned at suction port lower in inlet manifold, can be avoided condensed water to converge to throttler valve and freeze; After car engine heats gradually, the condensed water converged can be heated and air flowing volatilization naturally, the normal work of motor can not be had influence on, this project organization is simple, be easy to manufacture and realize, prevent the water causing closure to freeze from source, the anti-closure in winter being generally applicable to vehicular petrol engine field freezes.
Description
Technical field
The utility model relates to automotive engine component field, particularly relates to a kind of engine intake manifold.
Background technique
Winter, vehicle was because of petrol engine operation with after stopping, water vapour from deaerator is met condensation and is formed the globule and be dispersed in intake manifold and throttle body wall in intake manifold, the globule progressively becomes large dripping and moves, finally converge in throttle body valve plate Background Region, freeze at throttle butterfly periphery after continuing for some time under low temperature, when causing engine start and run, throttle butterfly can not with engine operating instructions action because being hampered, do not reach target location, form engine speed fluctuations, vehicle time serious, will be caused to enter closure power-off Claudication states.
For more than, the common solution that current industry is taked has: 1, arrange throttle butterfly action, to carry out opening ice of throttle body, but needing to arrange that exploitation has the private section valve gear of the function that opens ice, there is risk in ability to work and the reliability of throttle body; 2, be incubated and heating measures engine intake manifold and throttle body, as arranged heating water cavity or heating resistor on throttle body, but these all can cause the change of motor and existing engine nacelle to design.Such scheme is substantially all control table work, and has larger change in design and cost increase, and the functional reliability of equipment also needs to consider.
Summary of the invention
Technical problem to be solved in the utility model is to provide the engine intake manifold that a kind of anti-closure freezes, the retaining cavity that one is positioned at suction port lower is set in this intake manifold, condensed water can be avoided to converge to throttler valve freeze, prevent the water causing closure to freeze from source, the anti-closure in winter being generally applicable to vehicular petrol engine field freezes.
The utility model is achieved in that the engine intake manifold that a kind of anti-closure freezes, comprise inlet manifold, the bottom surface of described inlet manifold is provided with a suction port, described throttle body is communicated with at suction port, throttler valve is provided with in described throttle body, the height on the interior edge of described bottom surface is higher than the outer of bottom surface, and the interior edge of described bottom surface is that the outer of bottom surface is away from air inlet side near air inlet side.
Described throttler valve is butterfly valve.
Described suction port is outside equipped with a circle checkdam.
The interior edge of described bottom surface is protruding, centered by suction port, makes bottom surface form the low slope that has a down dip of middle high surrounding.
The engine intake manifold that the anti-closure of the utility model freezes is without the need to making larger structural change to engine aspirating system, also without the need to being incubated and heating measures engine intake manifold and throttle body, by arranging the retaining cavity that is positioned at suction port lower in inlet manifold, condensed water can be avoided to converge to throttler valve and to freeze; After car engine heats gradually, the condensed water converged can be heated and air flowing volatilization naturally, the normal work of motor can not be had influence on, this project organization is simple, be easy to manufacture and realize, prevent the water causing closure to freeze from source, the anti-closure in winter being generally applicable to vehicular petrol engine field freezes.
Accompanying drawing explanation
Fig. 1 is embodiment 1 structural representation of the engine intake manifold that the anti-closure of the utility model freezes;
Fig. 2 is embodiment 2 structural representation of the engine intake manifold that the anti-closure of the utility model freezes.
In figure: 1 inlet manifold, 2 throttle bodies, 3 throttler valves, 4 bottom surfaces, 5 suction ports, 6 checkdams, 7 storage chambers, 8 condensed waters.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model statement.
Embodiment 1
The engine intake manifold that a kind of anti-closure freezes, comprise inlet manifold 1, the bottom surface 4 of described inlet manifold 1 is provided with a suction port 5, described throttle body 2 is communicated with at suction port 5, throttler valve 3 is provided with in described throttle body 2, the height on the interior edge of described bottom surface 4 is higher than the outer of bottom surface 4, the interior edge of described bottom surface 4 is near suction port 5 side, the outer of bottom surface 4 is away from suction port 5 side, the bottom of inlet manifold 1 is made to form a storage chamber 7, condensed water 8 is concentrated in storage chamber 7, the region of throttler valve 3 can not be flow into again, because icing effect is to the action of throttler valve 3, in the present invention, described throttler valve 3 is butterfly valve.
In the present embodiment, as shown in Figure 1, described storage chamber 7 realizes by arranging a checkdam 6, and described suction port 5 is outside equipped with a circle checkdam 6, is blocked the condensed water 8 of convergence by checkdam 6, ensures the regular event of throttler valve 3.
Embodiment 2
The engine intake manifold that a kind of anti-closure freezes, the difference of embodiment 2 and embodiment 1 is, as shown in Figure 2, the interior edge of described bottom surface 4 is protruding, centered by suction port 5, make bottom surface 4 form the low slope that has a down dip of middle high surrounding, the condensed water 8 of convergence nature converges to bottom surface 4 outer along the slope that has a down dip can not enter throttler valve 3 flowing in throttle body 2, would not because of icing effect to normal action in such throttler valve 3.
