Description

Technical Field [0001] The present invention relates to a manifold water dispenser,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for distributing condensed water to an intake manifold so as not to affect the engine, and more particularly, to an apparatus for disturbing condensed water formed due to a temperature difference inside a manifold, .

It should be understood that the following description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as adhering to the prior art already known to those skilled in the art.

The intake manifold is an apparatus that supplies the air required for internal combustion of the engine and plays an important role in the combustion efficiency of the engine. The amount and speed of the air flowing inside the intake manifold increases together with the increase in engine speed.

On the other hand, in the intake manifold, condensed water is generated due to the difference between the engine and the outside air temperature. This condensed water flows into the engine cylinder together with the air as the number of revolutions of the engine increases, thereby corroding the engine.

Particularly, when the engine rotates at a high speed, condensed water flowing with the air flows at a high speed, resulting in problems such as engine failure.

The present invention proposes a manifold condensed water dispersing device for inserting a honeycomb structure at an inlet of an intake manifold and disturbing condensed water flowing into the engine so that the engine can be stably driven. There is a purpose.

The intake manifold of the manifold condensate dispersing apparatus according to an embodiment of the present invention includes an inlet, a runner, and a surge tank. The inlet portion is connected to the throttle body so that outside air is introduced.

The runner may be provided with a plurality of cylinders connected to the cylinders of the engine.

The support bracket is provided between the inlet portion and the plurality of runners, and guides and distributes the air so that air is smoothly moved and distributed from the inlet portion to the plurality of runners. Further, the intake manifold further includes a collision plate.

The impingement plate is installed inside the inflow portion so that the impingement plate blocks at least a part of the air flow path so that the condensed water is broken by the impact when the condensed water flows into the combustion chamber by the movement of the air.

The surge tank portion includes a distribution portion connected to a plurality of runners and a guide portion integrally connected to the distribution portion and having only a single passage therein. The impingement plate can be installed in the inner passage of the guide portion.

The inlet portion is horizontally coupled to one end of the guide portion. The impingement plate may be installed in front of a portion of the guide portion coupled with the inflow portion.

The guide portion includes a bottom surface inclined at an inclination angle of less than 7 degrees with respect to the horizontal. The impingement plate may be installed to cover at least a part of the bottom surface.

The impingement plate comprises a semicircular plate. The curved corner portion of the semicircle can be fixed and installed on the inner surface of the surge tank portion.

The impingement plate is a semicircular plate, and includes curved corner portions and straight corner portions. The curved corner portion is in contact with the guide portion, and the straight corner portion is in noncontact.

The impingement plate includes a plurality of first grooves formed in one direction and a plurality of second grooves formed to be staggered with the first grooves.

According to the manifold condensed water dispersing apparatus having the above-described structure, even if the condensed water accumulated in the intake manifold is dispersed in the engine cylinder, the engine can be prevented from corroding or malfunctioning due to natural evaporation due to the heat of engine combustion.

In addition, the effects of the present invention have various effects such as improving the durability of the engine according to the embodiment, and such effects can be clearly confirmed in the description of the embodiments described later.
