Abstract

Sistema de recalibração do cálculo da mistura Ar/combustível em veículo movidos a motor de combustão. Patente de Invenção de um sistema eletrónico que permite uma redução de consumo de combustível e emissão de gases poluentes. A presente invenção tem como foco buscar uma melhoria na UCE (Unidade de comando eletrónico), resultando na otimização de cálculo do combustível que a UCE realiza. A UCE calcula a quantidade de combustível a ser injetada pelo bicos injetores, em função da quantidade (massa) de ar que está sendo admitido pelo coletor de admissão do veículo. Existe uma formula que rege essa relação (ar/combustível). Essa formula possui uma relação chamada relação estequiométrica. Essa relação estequiométrica rege que idealmente uma combustão deva ter uma quantidade específica de combustível para uma determinada massa de ar que está sendo admitida. Nosso desenvolvimento se baseia no melhor controle da quantidade de ar que está sendo admitido no coletor. Utilizando o conceito que na Combustão real é necessário um excesso de ar para que possa ter a melhor combustão possível, é que desenvolvemos um dispositivo que influencia a central para modificar o calculo da melhor proporção da mistura ar/ combustível. A presente patente atua, dentre outros fatores, na correção do cálculo para o uso do melhor MAPA ou partes dele, a ser aplicado no veículo obtendo um melhor desempenho de redução de combustível e emissões gases. Esta tecnologia é aplicada a motores a combustão que utilizam gasolina, álcool, mistura dos dois (Flex Fuel). Como o principio da combustão sempre usa uma mistura ar/combustível, a tecnologia pode ser desenvolvida para o ciclo Diesel, GNV e Querosene de Aviação. Ainda nào foi testado em Diesel, GNV e Querosene de Avião, mas já estamos em fase final de desenvolvimento e testes para estas aplicações. Acreditamos que para Diesel a redução de emissão de gases será ainda maior. No caso de aplicação aeronáutica, o maior ganho será na economia de consumo de combustível.
