Abstract
"SISTEMA PARA OPERAçãO ECOLóGICA DE MOTORES DO CICLO DIESEL UTILIZANDO O PROCESSO DE INJEçãO ADIABáTICA DE ETANOL HIDRATADO SATURADO NO COLETOR DE ADMISSãO". Consistindo de uma válvula eletrónica de injeção de combustível (3) instalada no coletor de admissão (1) de motores do ciclo Diesel (4) tendo por objetivo injetar etanol hidratado em quantidade tal que todo o combustivel seja vaporizado previamente à sua admissão pelos cilindros (2) pelo processo de saturação adiabática, garantindo um menor débito de óleo diesel aos cilindros, podendo-se obter redução em até 30%, em massa, ganhando-se muito em redução de poluentes emitidos para a atmosfera e em melhoria da eficiência da combustão da mistura. A redução da temperatura do ar no coletor de admissão devido à vaporização do etanol hidratado, que possui um alto calor latente de vaporização, é suficiente para substituir o uso do "intercooler" em motores dotados de turbo-compressor, reduzindo-se os custos de fabricação dos mesmos e obtendo-se ganhos em termos de eficiência volumétrica do motor. O uso de etanol hidratado com maiores porcentagens de água que o usualmente comercializado é perfeitamente viável e implica em menores custos de produção para este combustível."SYSTEM FOR THE ECOLOGICAL OPERATION OF DIESEL CYCLE ENGINES USING THE HYDRATED ETHANOL INJECTION PROCESS IN SATURATED INTAKE COLLECTOR". Consisting of an electronic fuel injection valve (3) installed in the intake manifold (1) of diesel cycle engines (4) with the purpose of injecting hydrated ethanol in such a quantity that all fuel is vaporized prior to its admission by the cylinders ( 2) by the adiabatic saturation process, guaranteeing a lower diesel oil flow to the cylinders, which can achieve a reduction of up to 30%, in mass, gaining a lot in reducing pollutants emitted to the atmosphere and improving combustion efficiency. of the mixture. The reduction of the air temperature in the intake manifold due to the vaporization of hydrated ethanol, which has a high latent heat of vaporization, is sufficient to replace the use of the "intercooler" in engines equipped with a turbocharger, reducing the costs of manufacture and obtaining gains in terms of volumetric efficiency of the engine. The use of hydrated ethanol with higher percentages of water than what is usually marketed is perfectly viable and implies lower production costs for this fuel.
