TECHNICAL FIELD

The present invention relates to the field of arts generally included in the international classification F02M and especially to the art of equipment for introducing blends of detergents into air intake manifolds, exhaust manifolds and combustion chambers of endothermic engines.

STATE OF THE ART

In previous technics exist equipments for introducing fluid detergents into air intake manifolds of endothermic engines with the aim to remove encrustments from manifolds, from valves and from their relative valve seats in the cylinder heads of engines. All equipments known do not make enable to visualize the grade of atomization of the blend of detergents. Furthermore, the systems known do not make enable to visualize neither the delivery of the liquid nor the optimization of the zone of introduction in predeterminate points of air intake manifolds, exhaust manifolds or combustion chambers.

The problem to risolve is in fact to realize equipment that enables to visualize the delivery and the grade of atomization of the blend of detergents. Furthermore, equipment should be realized which is easy adjustable and higly reliable also in operations of connection with various types of air intake manifolds, exhaust manifolds or combustion chambers, even in presence of apparatus depending on the air intake of the engines.

DESCRIPTION

The present invention will be best understood from the following detailed description when read in conjunction with the accompanying drawings presented as a non restricting example, in which

FIG. 1 illustrates the equipment not connected and showing the atomization tip of the feeding tube in a undetermmated position It is noted, that the marker ring 8 is in a retracted position in respect of bulb 4.

FIG. 2 illustrates the equipment not connected, but with the tip of the feeding tube already in a predeterminate position in relation to the dimensions of, in this example, an air intake manifold 3 It is noted, that the slidable marker ring 8 has been placed against the transparent bulb 4

FIG. 3 illustrates the beginning of the phase of connection of the equipment to an air intake manifold of an endothermic engine It is noted, that the auxiliary tube 7 has been disconnected from the air intake manifold in order to allow the connection of the detergent equipment It is noted, furthermore, that the marker ring 8 preserves still its predeterminate position on the retracted feeding tube exactly to be able to set it afterwards against the transparent bulb 4 FIG 4 illustrates the equipment already completely connected to a source of a detergent fluid 12 and downstream to the air intake manifold 3 of the engine It is noted, that the tip 1 is in the inside of the transparent bulb 4 for visualizing the delivery and the grade of atomization of the detergent fluid 5 It is noted, also, that the marker ring 8 is in a retracted position It is noted, furthermore, that the auxiliary tube 7, disconnected from joint 11 , is now connected to joint 6 at the side of the visualizing bulb 4

FIG 5 illustrates the equipment in working phase It is noted, that the tip of the feeding tube is in a predeterminate invisible position at the inside of the air intake manifold That position is demonstrated by

the external and therefore visible position of the marker ring 8 which is in contact with the transparent bulb 4. It is noted, also, that during the detergent operation the auxiliary tube 7 is connected to joint 6 of the equipment in order to allow simultaneous functions of the auxiliary apparatus also during the operations of the regulation of the delivery and the grade of atomization of the detergent fluid, which is supplied by the source 12, by means of the regulating device 9.

For a better understanding of the drawings each detail is marked as follows:

(1 ) indicates the atomization tip of the feeding tube of the blend of detergents; the position of that tip, which is invisible at the inside of the air intake manifold, exhaust manifold or combustion chamber of the engine, can be predeterminated and verified from the outside

(2) indicates the feeding tube, which is connected to a source of a detergent fluid, which has to be atomizated, dosed and introduced into a predeterminate zone of air intake manifolds, exhaust manifolds or combustion chambers of endothermic engines

(3) indicates the air intake manifold of an endothermic engine, which could be also an exhaust manifold or combustion chamber and could be of various shapes and various dimensions and indicates the predetermination of the exact optimised position of the atomization tip of the feeding tube by letting slide from the

outside the feeding tube, which is equipped with a ring to mark the position of the tip

(4) indicates a transparent bulb which allows to visualize the delivery and the grade of atomization of the blend of detergents

(5) schematizes the visibility of the delivery and the grade of atomization of the blend of detergents during the phase of regulation. It is noted, that tip 1 of tube 2 is positioned expressly inside the transparent bulb

(6) indicates a three-way joint fitted on the equipment downstream of the transparent bulb. This joint is meant to connect the auxiliary tube of apparatus depending on the air intake of the engine to the equipment

(7) indicates an auxiliary tube which connects eventual auxiliary apparatus to the air intake manifold

(8) indicates a marker ring fitted around the feeding tube and placed against the transparent bulb to indicate the exact predeterminate position of the atomization tip at the inside of the manifold or combustion chamber to deterge

(9) indicates a regulating device of the delivery and the grade of atomization of the blend of detergents

(10) indicates a tube which connects the equipment to a source of a fluid detergent

(11 ) indicates a joint fitted on the air intake manifold to connect auxiliary apparatus

(19) indicates an electrovalve commanded by the timers (15) and (16)

(20) indicates the fixture tip of the grooved stem (24) inside the feeding tube

(21) ndicates a sliding valve on the stem (24) (22) ndicates a spring which closes the valve (21) (23) ndicates the external tip of the stem (24) ndicates the stem on which slides the valve (21) (25) ndicates the blend of detergents opening the valve (21 )

The obviousness of the drawings put in evidence the practicality, the simplicity of operation and the reliability of the equipment in discussion. In fact, by means of a simple manouvrement of sliding the tube 2, the operator predetermines the exact position which the atomization tip 1 will have to assume at the inside of any kind of air intake manifold, exhaust manifold or combustion chamber 3. This predeterminate position is been demonstrated by the marker ring 8 which is positioned against the bulb 4. Successively the operator proceeds with the connection of the equipment to a source of a fluid detergent 12, to the manifold or combustion chamber 3 and to eventual auxiliary tubes 7. After having done all the connections the operator retracts the tube 2 until the atomization tip 1 will be at the inside of the transparent bulb 4; in this way it will be possible to optimize the grade of atomization of the blend of detergents and to regulate its delivery with the device 9. Afterwards, the operator will have to put the atomization tip 1 of tube 2 in the predeterminate position, which is invisible because in the inside of the manifold or combustion chamber 3, but demonstrated by means of the marker ring 8 positioned against bulb 4. Once all operations have been carried out, the equipment will perform the detergent operation at maximum reliability.

Naturally, the invention is subject to various modifications of practical realization considering the structural dimensioning of the various components and the technical choice of the materials used. It is thus obvious that are part of the basic principle of this invention all those equipment for visualizing and regulating the delivery and the grade of atomization and for optimizing the zone of introduction of a blend of detergents into air intake manifolds, exhaust manifolds or combustion chambers of endothermic engines having the inventive combination as described, illustrated and hereafter claimed.
