Abstract
An induction manifold for a minicar engine relates to an engine unit of a car which comprises a stabilivolt cavity, four air inlet pipes, a mounting flange and a thermostat base and is mould cast integrally. Said air inlet pipes are of tiny camber, said stabilivolt cavity is a hollow cavity similar to an outlined letter 'T' in shape and is assembled with a rectangle and an irregular tetrahedron; the cavity wall is provided a reinforced rib, the four air inlet pipes with tiny camber are connected side by side to a side of a rectangular portion. The induction manifold for a minicar engine has optimum product structure and excellent performance. The air inlet pipes with tiny camber have enlarged inner diameter and help to increase volumetric efficiency of the engine when running with high speed, and improve compentency of air flow passing through the induction manifold. The stabilivolt cavity shaped like an outlined letter 'T' has enlarged capacity and help improve volumetric efficiency. Furthermore, the combustion quality of the engine is improved, also the bulk volume is decreased, the weight is reduced, and the material consuming is decreased. So beneficial effects are achieved in increased power, increased torque and reduced fuel consumption.When the induction manifold is applied to an engine of a minicar.

Technical field:
The utility model relates to a kind of automotive engine component, particularly a kind of little car engine intake manifold.
Background technique:
Existing intake manifold is as shown in Figure 6: be made up of and integral casting forming suction tude 11, mounting flange 13, the thermostat base 10 of 12,4 bendings of pressure stabilizing cavity.The deficiency that this technology exists is: one, the pressure stabilizing cavity volume is less than normal, the inflation requirements in the time of can not satisfying high rotating speed; Two, the suction tude camber is bigger, and middle and high fast intake resistance is big, and three, the suction tude internal diameter is little can not satisfy motor inflation requirement, four, the big material consumption of weight is more, the cost of production height.
The model utility content:
The utility model purpose is to provide a kind of product structure optimization, performance is good, can improve manifold suction tude air-flow passing capacity, and then the charging efficiency of lifting motor, improve the burning quality of motor and little car engine intake manifold of other performances, to solve existing intake manifold above shortcomings part.
The technological scheme that solves the problems of the technologies described above is: a kind of little car engine intake manifold, form and integral casting forming by pressure stabilizing cavity, 4 suction tude, mounting flange, thermostat bases, it is characterized in that: described suction tude is the suction tude of little camber, described pressure stabilizing cavity is the approximate hollow cavity of " protruding " font that is constituted by cuboid and irregular tetragonal body, and the suction tude of 4 little cambers links to each other with a cuboid shape side partly of pressure stabilizing cavity side by side.
As another feature of the present utility model be: on the described pressure stabilizing cavity wall stiffening rib is arranged;
As another feature of the present utility model be: the internal diameter of the suction tude of described little camber is bigger by 5%～10% than the internal diameter of the existing crooked suction tude of motor of the same type, and length reduces 15%～25%;
As another feature of the present utility model be: the volume of the existing pressure stabilizing cavity of the volume ratio of described pressure stabilizing cavity is big by 10%～20%.
Because adopt said structure, little car engine of the utility model is compared with intake manifold with existing little car engine with intake manifold, has the following advantages:
Charging efficiency when 1, little car engine of the utility model adopts the little camber suction tude that adds large diameter to help to improve high engine speeds with intake manifold;
2, adopt by rectangular build and add the volume that pressure stabilizing cavity that approximate square body constitutes the approximate hollow cavity that falls " protruding " font has increased pressure stabilizing cavity, help to improve charging efficiency;
3, in pressure stabilizing cavity, increase the rigidity that stiffening rib has improved pressure stabilizing cavity;
4, length reduces because suction tude internal diameter of the present utility model strengthens, thereby the intake manifold overall volume reduces, weight saving, reduced the material consumption.
Based on above-mentioned advantage, little car engine of the utility model is applied to intake manifold and has obtained on the little car engine of certain type that power ascension 15%, moment of torsion improve 10%, rate of fuel consumption reduces by 15% beneficial effect.
Below, in conjunction with the accompanying drawings and embodiments a kind of little car engine of the utility model technical characteristics with intake manifold is further described.
