Definitions

  • the subject of the invention is a device (degasser) for a preparation of liquefied petroleum gas, preferably butane, propane, intended to be dosed to an internal combustion engine as fuel in a gaseous state to reach optimal reactivity in gasification.
  • the so-called petroleum gas is retailed in a liquefied state under a pressure of about 4 - 15 bar.
  • the technical problem solved by the present invention is how to design a device for a preparation of gas from a liquid state to a gaseous state as fuel under a pressure of about 0.9 - 3.5 bar that will have optimal reactivity and proper combustion based on a current consumption or on a need for supplying a proper quantity of properly pressurised gas, and that will deliver through injection electronics a proper mixture of fuel and air.
  • the device of the invention is also adapted to be initially or subsequently installed into any vehicle.
  • Known vaporizers of this type are designed as a vessel separated by a thermally conductive material (usually aluminium or an aluminium alloy is used due to an acceptable price) that separates a water heated section from a gas evaporating section.
  • the shape of the vessel must contribute to an optimal transfer of temperature from the water section to the gas section and thus ensure quick and efficient gasification.
  • the shape of the gas section is such that the gas is pushed against the wall when transferred through the vessel, as a contact of gas with an aluminium medium causes efficient gasification.
  • Known vaporizers of this type come in various shapes and due to various shapes centrifugal forces and/or turbulences are created due to which the gas in a vaporizing stage comes in contact with aluminium walls in order to reach efficient vaporization (Fig. 4).
  • a drawback of known solutions is that turbulences (9) that appear behind barriers, due to which a gas in drops contacts the walls, cause undesired side effects, such as a slower flow and reduced reactivity of a reducer.
  • a slower flow means poor reactivity and a too slow regulation of a proper quantity of fuel under the proper required pressure.
  • a too small quantity of pre-prepared fuel under a too low pressure causes supply of a too poor mixture of fuel, which increases combustion temperature and can consequently damage engine parts of a vehicle.
  • a solution to the technical problem would be a laminar medium, the production of which in a closed tight vessel is extremely demanding and economically unacceptable. Due to its huge contact surface a laminar medium causes an optimal transfer of heat energy.
  • the described technical problem is solved by a device of the invention that is characterized in that a medium of heat energy transfer is shaped in laminar curves.
  • the device is thus optimised through a reduced number of lamellas and their bending, which causes gas mixing and bouncing of gas from the walls, yet does not cause a turbulent flow, which is the cause in known solutions of this type for a slower flow of gas through a gasification vessel, for a lower efficiency, and for improperly prepared fuel.
  • a bent laminar flow causes a high level of heat energy transfer and efficient vaporization of liquefied petroleum gas for the preparation of use of the latter in a gaseous state in internal combustion engines.
  • a device consists of a vessel composed of a water heating section (1 ) and a pressure vaporizing, gasifying section (2).
  • a valve (3) for a supply of liquid gas into the vessel can be mechanical with a membrane or an electromagnetic valve controlled by electronic and sensors for a controlled flow of liquefied gas into the gasifying section of the vessel.
  • the objective of the device according to the invention is to provide the required over pressure above the pressure in an intake collector of an internal combustion engine at an outlet (4) of gas from the gasifying section, and consequently on gas injectors that are not part of the invention.
  • the essential part of the device is bent lamellas (5, 6) having a thickness ranging from 0.50 mm to 5.00 mm, and a height from 5 mm to 30 mm, wherein the bending of lamellas is defined by curves shaped like parts of circular curves, ellipse parts, sinusoid shapes and similarly curved shapes; the bending radius of lamellas lies in a range of diameter from 5.00 mm to 30.00 mm of said possible shapes and bending can pass from one shape to another also via a flat part of a lamella and various radii of said possible shapes.
  • the gas used is liquefied petroleum gas that is available on the market under a pressure of about 4 - 15 bar (butane, propane). From the economical point of view of huge series production it is reasonable to produce a dimensionally adapted device of the invention for an individual engine type.
  • the gas first enters the gasifying section (2) of the vessel and is then separated into two or several parallel flows separated by lamellas (5). As the lamellas are bent, the gas travels from one lamella to another and comes in contact with both, thus reaching optimal vaporization, gasification by giving away heat energy. A reverse function is performed by lamellas (6) on the water heating section (1 ). Water or another medium enters the water section of the vessel and is then separated in two or several parallel flows. The bent lamellas (6) cause the water to mix and contribute to a smooth and optimal transfer of heat energy from the water section to the medium of heat energy transfer from the water section to the gasifying section of the vessel (the medium is normally an aluminium alloy).
  • the cross-section of the flow of water or another medium in the water section (1 ) should amount to at least 0 1 1.00 mm.
  • the cross-section can be smaller, yet in this case it is necessary to have a parallel connection to the cooling system of the engine or a connection to a part that will not cause a negative effect due to a restricted flow of a cooling liquid.
  • the cross-section of gas flow must be taken into consideration.
  • the intermediate wall, on which lamellas are arranged, between the water and the gasifying sections must be as thin as possible, yet still allow gas tightness in the gasifying section (2) of the vessel up to legally determined pressures.
  • the lamellas (6) in the water section (1 ) and the lamellas (5) in the gasifying section (2) must be offset by a smallest possible value as allowed by manufacturing processes.
  • the valve (3) is controlled by an electromagnetic or a servo-operated valve. Control is done by electronics that guides the valve (3) based on the required over pressure between the pressure in the intake collector and the pressure of the gas at the outlet from the gasifying section or the pressure on injectors that is measured through adequate sensors, or through a valve (3) controlled by a membrane and ensuring the required over pressure mechanically.

Abstract

L'invention concerne un dispositif de préparation de gaz de pétrole liquéfié à doser dans un moteur à combustion interne, ledit dispositif étant caractérisé en ce qu'un moyen de transfert d'énergie thermique est façonné en courbes laminaire. Comme illustré, le gaz pénètre dans la zone de gazéification (2) d'une enceinte et est ensuite séparé en deux ou plusieurs flux parallèles séparés par des lamelles (5). Le cintrage des lamelles (5) provoque le déplacement du gaz d'une lamelle à l'autre et son contact avec les deux, ce qui permet d'obtenir une vaporisation optimale et une gazéification par dissipation d'énergie thermique. Une fonction inverse est réalisée par des lamelles (6) dans une zone d'eau (1). L'énergie thermique dans la zone d'eau (1) est transférée aux lamelles cintrées (6) qui transfèrent l'énergie thermique aux lamelles (5) dans la zone de gazéification (2). Le gaz de pétrole liquéfié qui pénètre dans l'enceinte par l'intermédiaire d'une soupape (3) est soumis à un écoulement forcé à travers les lamelles cintrées (5) et entre en contact actif avec les lamelles (5), absorbant ainsi l'énergie thermique.
