Abstract

resumo o presente invento fornece um método e módulo de detecção do teor de álcool em álcool combustível. o método compreende as seguintes etapas: coleta teor de oxigênio o(n) no sistema de escape de automóveis; a obtenção de uma relação de ar-combustível ac(n) de acordo com o(n) e um teor de etanol pré-definido ap(n); a obtenção de um volume de injeção de combustível fc(n) de acordo com o ac(n) e uma entrada de ar no motor g; o cálculo do desvio de combustível fd(n)=[fc(n)-fp(n)]/ fp(n), em que f p(n) é uma quantidade predefinida de injeção de combustível; obtenção de um desvio do teor de etanol ad(n) de acordo com fd(n); o cálculo do teor de etanol atual de ar(n)=ad(n)+ap(n); altera ap(n+1); e obtenção uma quantidade de injeção de combustível atual fr(n) de acordo com ar(n); alteração de fr(n+1); injeção do combustível de acordo com a quantidade fr(n) , e as referidas etapas de circulação; quando o valor absoluto de fd(n) for inferior a um valor de desvio de combustível estável s, parar a circulação. o método de detecção do teor de álcool de álcool combustível de acordo com a presente invenção pode detectar o teor de etanol no combustível, e melhorar o desempenho da utilização de veículos de combustível.Summary The present invention provides a method and module for detecting alcohol content in combustible alcohol. The method comprises the following steps: collects oxygen content o (n) in the car exhaust system; obtaining an air-fuel ratio ac (n) according to (n) and a predefined ethanol content ap (n); obtaining a fuel injection volume fc (n) according to ac (n) and an air intake in the engine g; calculating the fuel drift fd (n) = [fc (n) -fp (n)] / fp (n), where f p (n) is a predefined amount of fuel injection; obtaining a deviation in the ethanol content ad (n) according to fd (n); the calculation of the current ethanol content of air (n) = ad (n) + ap (n); change ap (n + 1); and obtaining a current fuel injection amount fr (n) according to air (n); change in fr (n + 1); fuel injection according to the quantity fr (n), and said circulation steps; when the absolute value of fd (n) is less than a stable fuel shift value s, stop circulation. The method of detecting the alcohol content of fuel alcohol according to the present invention can detect the ethanol content in the fuel, and improve the performance of fuel vehicle use.
