Description

a) O rendimento de um motor endotermico,estã dependente do nível da taxa de compressão· Com maior relêvo nos motores de explosão,esta taxa tem tido um limite,o qual lhe é impôsto pelos fenómenos de detonação consequentes,se Ssse limite fôr excedido. Para tornar possível o aumento dêsse limite,usa-se juntar aditivos âs gasolinas (como exemplo,o tetra-etilo de chumbo),os quais são poluentes,e a tendência actual ê para a sua completa exclusão,a) The performance of an endothermic engine is dependent on the level of the compression rate · With greater relief in the explosion engines, this rate has had a limit, which is imposed by the consequent detonation phenomena, if this limit is exceeded. To make it possible to increase this limit, it is used to add gasoline additives (for example, lead tetraethyl), which are pollutants, and the current trend is towards their complete exclusion,

b) 0 excesso de temperatura nas paredes da câmara de combustão,tem sido conduzido para o radiador,onde ê dissipado,resultando perdas de energia no sistema,b) The excess temperature in the combustion chamber walls has been conducted to the radiator, where it is dissipated, resulting in energy losses in the system,

c) Encontrou-se uma solução simples e económica,que resolve em simultâniojos dois problemas atrás referidos,c) A simple and economical solution was found, which simultaneously solves two problems mentioned above,

JUSTIFICAÇÃO:JUSTIFICATION:

a) A combustão da gasolina ê uma reacção química - cuja velocidade pode ser moderada,se intercalar-mos entre as moléculas reactivas (hidrocarbonetos + oxigénio),uma molécula inerte (não reactiva), A substância,para o efeito,practicamente inerte sob o ponto de vista químico (mas fisicamente activa),que se propãe,ê o vapor de égua,a) The combustion of gasoline is a chemical reaction - the speed of which can be moderated, if we intercalate between reactive molecules (hydrocarbons + oxygen), an inert (non-reactive) molecule. The substance, for this purpose, practically inert under the chemical point of view (but physically active), which is proposed, is mare vapor,

b) Em consequência,as moléculas de vapor de égua,são introduzidas na câmara de combustão conjuntamente com a mistura gasosa e têm umab) As a result, the water vapor molecules are introduced into the combustion chamber together with the gas mixture and have a

tripla função:triple function:

l) A primeira S,como jS foi referido,uma acção moderado:l) The first S, as already mentioned, a moderate action:

reacção,fazendo baixar a velocidade desta,de acôrdo com a maior proporção de vapor de Sgua,em relação com a mistura gasosa* 5je aplicarmos uma maior proporção de vapor,poderemos,por isso,aumentar a taxa de compressão (sem que se produzam fenómenos de detonação) .reaction, lowering its speed, according to the highest proportion of water vapor, in relation to the gas mixture * 5j and applying a higher proportion of steam, we can therefore increase the compression rate (without the occurrence of phenomena detonation).

Nos testes efectuadas,a taxa de compressão (cujo máximo nos motores de explosão,ê em média de 9/1 ) foi elevada para 14/l com a proporção de vapor de âgua seguinte:In the tests carried out, the compression ratio (whose maximum in the explosion engines is on average 9/1) was raised to 14 / l with the following proportion of water vapor:

pêso do vapor de Sgua = a 15# do pêso da gasolinasgua steam weight = to 15 # of gasoline weight

Entretanto pode prever-se que se pode aumentar a taxa de compressão,para um nível mais elevado (por exemplo 22/l),se aumentarmos a proporção de vapor·In the meantime, it can be anticipated that the compression ratio can be increased to a higher level (for example 22 / l) if we increase the proportion of steam ·

2) A segunda função (de natureza física) ê a de absorver calor das paredes da câmara de combustão (calor que iria dissipar-se no radiador) e consequentemente expandir-se· Esta expansão gera potência que vai adicionar-se à produzida pela combustão da gasolina.2) The second function (of a physical nature) is to absorb heat from the walls of the combustion chamber (heat that would dissipate in the radiator) and consequently expand · This expansion generates power that will be added to that produced by combustion of gasoline.

3) A terceira função ê de natureza mecânica,pela razão de o vapor de água ir beneficiar o trabalho do pistão,pois que - sendo deficiente a lubrificação do topo do cilindro - esta ê melhorada com a acção refrigerante e lubrificante do vapor.3) The third function is of a mechanical nature, for the reason that the water vapor will benefit the work of the piston, since - if the lubrication of the cylinder top is deficient - it is improved with the cooling and lubricating action of the steam.

DESCRIÇÃO ιΟ processo ê realizado pela forma seguinte:DESCRIPTION The process is carried out as follows:

l) D fluxo de ar que alimenta o carburador do motor ê dividido â salda do filtro do ar (l),pelo menos,por dois circuitos: a) um de secção maior (2) que alimenta directamente o carburador (10). b) um de menor secção (3) que se dirige para um alimentador de Sgual) The air flow that feeds the engine's carburetor is divided into the air filter outlet (l) by at least two circuits: a) one of larger section (2) that directly feeds the carburetor (10). b) one of smaller section (3) that goes to a Water feeder

(4)? Cada um dêstes circuitos ê interceptado,parcialmente,por válvulas (5) e (6),de preferência do tipo mariposa. Estas estão orientadas,de preferência,numa posição de natureza ortogonal e do seu accionamento resulta uma variação da velocidade do fluxo nos dois circuitos,e,em consequência - uma variação da quantidade de água debitada pelo alimentador (4)(êste encontra-se calibrado de acÕrdo com a proporção requerida pelo nivel da taxa de compressão),de modo a corresponder ao equilíbrio do nivel de temperatura das paredes da câmara de combustão.(4)? Each of these circuits is partially intercepted by valves (5) and (6), preferably of the moth type. These are preferably oriented in a position of an orthogonal nature and their activation results in a variation of the flow speed in the two circuits, and, consequently - a variation in the amount of water charged by the feeder (4) (this is calibrated according to the proportion required by the level of the compression rate), in order to correspond to the equilibrium of the temperature level of the combustion chamber walls.

2) Um vaporizador,de preferência uma pequena panela (7),a qual tem o fundo introduzido,de forma apropriada,na salda do colector (8)de escape dos gases do motor,e ê aquecida por êstes gases,onde a água recebida do alimentador (4)- o qual está sobrepêsto à abertura da panela - ê transformada em vapor. 0 mesmo fluxo de ar que passou pelo alimentador,transporta o vapor de água para o colector (9), juntando-se ao fluxo principal,seguindo para o carburador (10) e câmara de combustão (ll),2) A vaporizer, preferably a small pan (7), the bottom of which is properly inserted into the outlet of the engine exhaust manifold (8), and is heated by these gases, where the water received the feeder (4) - which is superimposed on the opening of the pan - is transformed into steam. The same air flow that passed through the feeder, carries the water vapor to the collector (9), joining the main flow, going to the carburetor (10) and combustion chamber (ll),

3) As válvulas (5) e (6),são accionadas em sincronia,por comando de um termástato que avalia a temperatura das paredes das câmaras de combustão,temperatura essa,que varia com as condiçSes de trabalho do motor e também com a natureza das condições atmosféricas (ar sêco e quente - necessita mais vapor;ar húmido e frio - menos vapor.3) The valves (5) and (6), are activated in sync, by command of a thermostat that evaluates the temperature of the combustion chamber walls, which temperature varies with the working conditions of the engine and also with the nature atmospheric conditions (dry and hot air - needs more steam; moist and cold air - less steam.
