Description
Technical field
The utility model relates to a kind of suction means of motor, especially is formed with to be used to supply with the suction means of motor that secondary adds the gas channel of gas.
Background technique
Be back to occasion in motor air-breathing making gas leakage or secondaries such as EGR gas add gas, though the person in charge from induction mnifold imports generally speaking, if but multicylinder engine, be difficult to that then secondary is added gas and distribute to each cylinder equably, in addition, because it is far away apart from each cylinder to import the position of secondary interpolation gas, so, be difficult to improve the control response performance that secondary adds gas.
Therefore, shown in patent documentation 1 and 2, the someone attempts importing secondary from the position of downstream one side of the air-breathing arm of induction mnifold to each cylinder and adds gas.That is to say that the structure shown in the patent documentation 1 is the gas channel that is formed for gas leakage is supplied to each cylinder on the mounting flange that is used for induction mnifold is installed on the engine body.Structure shown in the patent documentation 2 is to make dividing plate between induction mnifold and engine body, is formed for EGR gas is supplied to the gas channel of each cylinder on dividing plate.

But, become wall stream attached to the phenomenon on the suction port in order to reduce the fuel that goes out from fuel injection valves inject, in addition, in order to improve the control performance that forms mixed gas, the mounting point of Fuelinjection nozzle need be moved on to downstream one side from the mounting flange of induction mnifold, Fuelinjection nozzle is directly installed on the cylinder cap.
But, if as patent documentation 1, want that secondary is added gas and supply to each cylinder, because the change of the mounting flange of induction mnifold is big, so, directly Fuelinjection nozzle is installed on the cylinder cap very difficult.
Promptly, at patent documentation 1, for upper portion towards the mounting flange of engine body at induction mnifold, make segmentation (ト one Na メ Application ト) formula with being used to supply with the gas channel that secondary adds gas, the mounting flange of the induction mnifold side direction that makes progress enlarges, the junction plane of engine body also upwards side direction enlarge.Therefore, because the mounting point of Fuelinjection nozzle and the restriction that setting angle is subjected to forming mixed gas hinder the main cause that it upwards enlarges so very big junction plane becomes, directly Fuelinjection nozzle is installed on the cylinder cap very difficult.In addition, because along with the maximization of the mounting flange of induction mnifold, the junction plane of engine body one side also must be made very big wall thickness by the relative datum face, so, when the casting cylinder cap, produce shrinkage cavity or density variation etc., the castability of engine body has also worsened.
In addition, even the induction mnifold of patent documentation 2, owing on the dividing plate between induction mnifold and the engine body, form EGR gas distributed the gas channel that supplies to each cylinder, this gas channel is being made the segmentation shape towards junction plane one side of engine body, so, with above-mentioned same, maximization along with dividing plate, the junction plane of engine body one side also must be made very big heavy wall, so the castability of engine body has worsened.In addition, owing to be to form the structural type that gas channel, EGR gas are supplied with from the downside of each air intake passage in the lower portion of dividing plate, so condensed water is stored in the gas channel, or solid is deposited in the gas channel, might blocking channel.
The model utility content
The purpose of this utility model is to provide a kind of mounting flange towards engine body of induction mnifold that need not make to maximize, and promptly secondary may be added the downstream one side directed induction mnifold to each cylinder of gas from induction mnifold.
The utility model is a kind of suction means of motor, possesses: the induction mnifold that is formed for importing air-breathing air intake passage; Be installed in the dividing plate between induction mnifold and the engine body.On dividing plate, form towards the 1st junction plane of induction mnifold and make 2nd junction plane towards engine body littler, form from the 1st junction plane and secondary added the gas channel that gas supplies to air intake passage to the 2nd junction plane and near the 2nd junction plane than the 1st junction plane.
According to the utility model, owing to utilize the space of making thicker the 1st junction plane one side of wall thickness, form secondary is added the gas channel that gas is directed to downstream one side, make the 2nd junction plane littler, so the junction plane that can suppress engine body increases than the 1st junction plane.Consequently, can prevent that the engine body wall thickness from increasing.
