Abstract

An induction regulator, e.g. a devise for reducing vehicle exhaust emissions and increasing mpg/kph. The regulator is contained within its own 'spacer' body. The regulator is angled within the 'spacer' body to allow it to create a vortex. It does this by vaporising the fuel by passing over and through a system of specially perforated discs with elongate apertures and creating a vortex within the inlet manifold. The regulator is fixed within the 'spacer' body by the fixing of specially adapted tabs fitted to the body of the regulator. The 'spacer' body complete with regulator is fitted, sealed and secured between the the faces of the inlet manifold and the carburettor/single point injection system body. The regulator may be heated either by a water jacket supplied from the engine cooling system (fig.6) or electrically (figure 1B).

Description

DESCRIPTION AN INDUCTION REGULATOR FOR AN INTERNAL COMBUSTION ENGINE The present invention relates to an induction regulator for an internal combustion engine.

An induction regulator is known from UK Patent Number 2099074 which is designed to compensate for irregularities in the supply to and demand for fuel from the engine and thus lead to improved fuel consumption, reduced exhaust pollution, and better fuel atomisation/vaporisation. For this purpose this known regulator is adapted to be disposed in the inlet manifold of the engine, downstream of the. carburettor/single-point injection body and comprises a single perforated element allowing passage of fuel air mixture therethrough, an open topped reservoir for retaining excess unvaporised fuel and a pair of mounting straps depending from the perforated element for fixing the regulator within the manifold. The ends of the straps may be bent outwardly at right-angles in order to permit them to be clamped between the manifold and the carburettor/single point injection body. The perforated element is disposed at an angle to the straps such that when the regulator is installed the perforated element is disposed at a defined angle to the manifold wall in order to optimise atomisation.

There are several drawbacks of this known regulator.

1. General fitting of the known regulator is awkward and the angle of it is never guaranteed to be between 15 to 25 degrees, it is rather'hit and miss', and the space between the manifold wall and the regulator is difficult to obtain and maintain, the depth within the inlet manifold is also difficult to judge.

2. The mounting straps. Because these straps are bent by the person installing the regulator within the manifold, it is very easy to bend the straps such that the single perforated element would not be disposed at the required angle to the manifold. Furthermore by bending the straps in this way the straps can be weakened and strain can result at the point where the end of each strap is clamped between the carburettor/single point injection system body and the inlet manifold. With time the straps could fall into the internal combustion engine, resulting in considerable damage to the engine.

3. The open-topped reservoir. By fitting any form of restriction into the inlet manifold, it has a choking effect

on the fuel-air mixture entering the engine. The open-topped reservoir is known to do this. c

3. The single perforated element. It creates a'swirling'effect to allow a better fuel air mix and atomisation/vaporisation. The single perforated element is of a material and hole size which also causes a choking effect on the fuel air mixture entering the engine.

4. Fitment of the device directly into the inlet manifold can only be done by an experienced qualified engineer, the depth, distance between the regulator and the manifold wall, have to be as accurate as possible, as has been mentioned previously in note 1. The original idea was to be a DIY fitment.

It is the aim of the present invention to provide an induction regulator for an internal combustion engine which overcomes or alleviates the problems associated with the known induction regulators.

In accordance with the present invention, there is provided an induction regulator for an internal combustion engine. The configuration is as follows. The regulator comprising of two to three specially perforated elements, each equally separated, contained within a circular disc bodied frame, for allowing the passage of fuel air mixture therethrough. The perforations will be slightly elongated in direct opposition to each disc. This is to enhance the vortex that is created, and to also reduce the loss of pressure of the fuel air mixture to the cylinders, and to also reduce the'choking'effect. Two securing tabs, fixed opposite each other, the manufacture of the body will include the securing tabs as part of the design. This is to allow the securing of the regulator. The present invention now incorporates a separate manufactured body that will fit between the face of the carburettor/single point injection system body and the face of the inlet manifold. It will be of the same configuration as that of the inlet manifold/carburettor/single point injection system face, in that the design and shape will allow direct fitment to these components. using a standard 0. 5mm gasket to seal the unit between these faces, however, the uppermost gasket will be manufactured to include a beading which will extend around the internal circumference of the gasket. It is designed to reduce the amount of liquid fuel on the wall of the'spacer'and direct this small amount of fuel to the centre of the regulator The regulator will be fitted and secured within the'spacer'A keyway is located at the top right comer of the'spacer', a keyway is also located at the bottom left corner of the'spacer'. This is to allow the securing of the tabs to the body of the'spacer'. If required the'spacer'unit can also be fitted with a separate thicker gasket on top of the'spacer'unit. This will ensure that there is no connection with the butterfly part of the carburettor/single point injection system body, when the throttle is open to its fullest capacity.

By using this securing method, an angle of approximately 18 degrees is obtained and maintained, once fixed into position, the depth, distance from the wall of the'spacer'and angle of the regulator will be permanently maintained without further adjustment. Built into the'spacer'and directly below each keyway will be fixed into the'spacer' a heater pad. This will directly apply heat to the tabs located at each of the keyways. This will ai ! ow the regulator to be preheated during the cold to warm up of the engine. At the same time the heater pads will give direct heat to the walls of the'spacer'unit thereby assisting in reducing the amount of liquid fuel that is present on the walls of the 'spacer'unit. The securing of the'spacer'body between the inlet manifold and the carburettor/single point injection system body will be by the normal method as given by the manufacturer, however, extended length bolts when the fitting is done from the top and the bolts are screwed into the carburettor/single point injection system body and into the inlet manifold, will require to be manufactured to allow this. The fitment where the securing bolts are already located in the inlet manifold body will also require that these bolts are either lengthened or an attachment is fitted to extend the length of the bolts as fitted to allow the'spacer'body to be secured. In both cases this will ensure that the'spacer'is fitted and properly secured to the components mentioned.

By way of example only specific embodiments of the present invention will now be described, with reference to the accompanying drawings, in which :-

Fig. 1 is a schematic view illustrating a regulator constructed in accordance with a first aspect of the present invention and located in the'spacer'unit. Figs. la, lb, show the alternative fitment within the'spacer'unit complete wth the heater pads.

Fig. 4 is a front view of one of the perforated elements contained within its own metal frame. 2 to 3 are fitted.

Fig. 5 is a cross section of the regulator showing the perforated discs within its own metal frame and fitted within the'spacer'unit. Complete with the beaded gasket and normal lower face gasket and also the thick gasket, if required to be fitted to the top of the'spacer'unit to prevent any connection with the butterfly system in the carburettor/single point injection system. Fig. 5A is the singlepoint injection system body/single choke carburettor Fig 5B is the extra thick gasket. Fig. 5C is the beaded top gasket. Fig 5D is the'spacer'body with the regulator fitted. Fig. 5E is the bottom gasket. Fig. 5F is the inlet manifold.

Fig. 6 is a top elevated view of the'spacer'body held within a water heater jacket The supply is from the engine cooling system. In this particular instance the outer jacket material of the'spacer'body would be of aluminium, with a central thin metal core to support the regulator Direct heat by way of the water from the engine's cooling system would be used to heat the core wall and subsequently the regulator by heat transferance.

In Fig. 1, a single regulator (the configuration of a single-point injection system) is shown disposed in the'spacer' body, downstream of the single-point injection system body. The regulator now comprises a frame in which a double to triple layer of specially manufactured discs which have been perforated and the perforations are elongated in the

direction of flow. Each disc will be evenly spaced and held within the frame by an indentation on three areas of the frame. The frame will have fitted two tabs, which will be pressed at the correct angles to allow fitment to the 'spacer'body. A keyway will be made within the'spacer'body one at the top and one at the bottom to allow the tabs to be fitted and secured. Above the keyway and within the'spacer'walls two heater pads will be fixed. The tabs will lay on and above the heater pads, a gasket will then be fitted to the base of the'spacer'unit thereby sealing and securing the lower tab within the'spacer'body. To the top of the'spacer'body will be fitted a specially manufactured and adapted gasket, which will have a beading around the inner circumference of the gasket and slightly overhang the inner'spacer'body wall. This is to ensure that any unvaporised fuel that would normally be left

to run down the wall is directed to the centre of the'spacer'body and onto the regulator. The regulator assembly is made of stainless steel, it is robust and will not react to the fuel mixture. All the required angles, perforations elongation's distances and depths will be finalise during the the manufacturing process. Should there be a twin choke or multi choke system the correct type'spacer'body and regulators will be manufactured to combat this.

In the preferred construction of the regulator the perforated plates would be at an angle of 18 degrees. However, it

is known that the angle can be varied between 10 and 30 degrees and remain functioning efficiently. The important point to note is although a single perforated gauze can create a vortex, this is of a low magnitude. With the fitment of the specifically designed perforated gauze/plate the vortex will become more efficient thereby ensuring that the fuel/air mixture is totally vaporised prior to the'bum'and also ensuring that any unvaporised fuel that would normally be running down the inner wall of the of the inlet manifold is now held within the'spacer'unit and directed

by the beading on the top gasket, thereby directing this unvaporised fuel directly into the centre of the regulator. In the event that the carburettor butterfly or the injection system of a single point injection body a further gasket would be fitted to and above the beaded gasket between the face of the upper'spacer'body and the face of the carburettor/

single-point injection system body. This would alleviate chance connection with the regulator. Finally, fitment of the regulator to the'spacer'body can also be secured as shown in diagrams at Fig. 1A and IB. In Fig I A a tab is at the lowest part of the regulator. The other side is supported by an elongated arm, which forms the angle of the regulator to that specified. Securing again will be as previously mentioned. A keyway will be formed within the 'spacer body on the bottom of the'spacer'body and secured as mentioned previously. In Fig IB, the regulator is fixed in place by two stainless steel pins through the regulator body and secured to the inner walls of the'spacer'body at the

required angle, this will dispense with the need of tabs. Heating will be done, again by heat transference, to the pins travelling through the regulator body, heater pads will be aligned to the pins within the'spacer'body.

Reference has been made to a separate'spacer'body, this body will now be called the'vortex'system throughout the said invention and will be referred to as such in all future correspondence. This is not to confuse it with the separate thicker gasket used in the system as a break between the carburettor/single point injection system body and the face of the'vortex'body (spacer body).

Notwithstanding the above, the alternative method of heat transference can be seen in Fig. 6. A water jacket'spacer' body made of aluminium as the outer'spacer'body with a central metal core. This would ensure that heat from the engine's cooling system would be used to heat the'spacer'inner central metal core and by heat transference the regulator. This will reduce the amount of liquid fuel running down and held on the inner core wall, thereby allowing a better vaporisation of the fuel, and, by heat transference to the regulator will allow it to work in a heated environment, thereby reducing emissions and increasing engine efficiency
