Description
Technical field
The utility model relates to the cleaning of car engine air admittance valve, particularly a kind of engine intake valve cleaning solution introducting interface.
Background technique
Due to oil quality problem, road traffic condition and environment and bad driving habits, cause automobile to exercise after several thousand kilometers can in engine fuel oil system suction valve, the carbon distribution that firing chamber is formed and colloid, particularly GDI engine produce suction valve and combustion-chamber deposit even more serious.
The carbon distribution of engine intake valve and firing chamber and colloid cause engine performance to decline, and is short of power, and oil consumption increases, and discharges overproof principal element, annoyings auto producer always, autoist.
Patent publication No. 203717124U discloses a kind of engine intake valve and combustion-chamber deposit on-line cleaning system for this reason, the cleaning solution input pipeline of this system is connected on the vacuum pipe that arranges in pipeline between closure and engine intake manifold, but the motor of reality does not arrange vacuum pipe between, the therefore cleaning solution input pipeline scheme how access is not concrete between the two; On manifold, normally utilize existing hole to import, cause the cleaning solution after importing to each cylinder air inlet valve skewness, cleaning performance is bad.
Summary of the invention
The purpose of this utility model is to provide a kind of engine intake valve cleaning solution introducting interface, by arranging an adjustable metal ring between closure and engine intake manifold, cleaning solution supplying tube is connected on metal ring, realizing cleaning solution is be dispensed to all air intake valves uniformly, improves cleaning efficiency.
To achieve these goals, technological scheme of the present invention is: comprise the throttle valve body and engine intake manifold that are provided with closure, the two is interconnected; Wherein, an annulus is set between described throttle valve body and engine intake manifold main entrance connection mouth, annulus upper and lower opening exports with throttle valve body respectively and intake manifold main entrance is tightly connected, and described annulus sidewall is at least provided with a cleaning solution introduction hole.
Scheme is further: described annulus is metal ring, around on described metal ring sidewall relatively, be symmetrically arranged with two cleaning solution introduction holes.
Scheme is further: described annulus is metal ring, is evenly distributed with four or six cleaning solution introduction holes around distance on described metal ring sidewall is equal.
Scheme is further: described annulus thickness is less than 15mm, and described metal ring endoporus upper and lower opening exports with throttle valve body respectively and intake manifold main entrance internal orifice smoothly docks.
Scheme is further: described annulus thickness is 8mm to 10mm.
The beneficial effects of the utility model are: by arranging an adjustable metal ring between closure and engine intake manifold, described metal ring sidewall average distance is provided with multiple cleaning solution input interface, cleaning solution supplying tube is connected on metal ring, realizing cleaning solution is be dispensed to all air intake valves uniformly, improves cleaning efficiency.
The utility model, under the prerequisite of existing Basic Design substantially not changing automobile, realizes engine intake valve and combustion-chamber deposit on-line cleaning, and realizing cleaning solution is that the uniform adjustment distributed is simple and practical.
Below in conjunction with drawings and Examples, the present invention is described in detail.
Accompanying drawing explanation
Fig. 1 is the utility model structural profile schematic diagram;
Fig. 2 is the utility model circle structure schematic diagram.
Embodiment
A kind of engine intake valve cleaning solution introducting interface, see Fig. 1 and Fig. 2, described introducting interface comprises the throttle valve body 1 and engine intake manifold 2 that are provided with closure, directly be interconnected as both prior aries, not having can for the connection vacuum tube of input cleaning solution, in order to cleaning solution being inputted between, an annulus 3 is set between described throttle valve body and engine intake manifold main entrance connection mouth, annulus upper and lower opening exports with throttle valve body respectively and intake manifold main entrance is tightly connected, described annulus sidewall is at least provided with a cleaning solution introduction hole 301, introduction hole is an open-work, in embodiment, because throttle valve valve body and intake manifold main entrance surface of contact are planes, therefore the surface of contact that described annulus is connected with throttle valve valve body is provided with annulus notch 302, " O " type rubber seal 4 is provided with in notch, described annulus and gas manifold main entrance surface of contact be provided with match with the annular groove that arranges in the plane of gas manifold main entrance change shape projection 303, this kind of structure ensure that annulus upper and lower opening is tightly connected throttle valve body outlet and intake manifold main entrance respectively.The diameter of the introduction hole in embodiment is 3.5mm to 4mm.Outside annulus, introduction hole has attacked screw thread, cleaning solution supplying tube by screwed connection on annulus.
In embodiment: described annulus can be plastic hoop or metal ring, the present embodiment uses alloy aluminum ring or stainless steel metal ring, around on described annulus sidewall relatively, be symmetrically arranged with two cleaning solution introduction holes.
Position circumferentially can ensure that the cleaning solution sucked can be sucked each cylinder equably in intake manifold main entrance to use middle adjustment cleaning solution introducing port, the suction valve carbon distribution of each cylinder is made to obtain uniform cleaning, simultaneously, also ensure that the cleaning solution quantity that each cylinder enters is the same, ensure the Security of cleaning, rotating ring just can regulate easily for it, but needs to unclamp locking.
In order to comprehensive convenient adjustment, described annulus is metal ring, is evenly distributed with four or six cleaning solution introduction holes around distance on described metal ring sidewall is equal.
In order to ensure that the former design of motor is not by large change as far as possible, in embodiment: described annulus thickness is less than 15mm, described annulus endoporus upper and lower opening smoothly docks with throttle valve body and intake manifold main entrance internal orifice respectively.
Preferably, in embodiment: described metal ring thickness is 8mm to 10mm.
