Abstract

Poder calcular la cantidad de inyección de combustible detectando la masa de aire de admisión sin usar un caudalímetro de aire. Una sección de cálculo de tiempo de compresión y escape 3 calcula respectivamente los tiempos de inicio y fin de lacarrera de compresión Tc1 y Tc2y los tiempos de inicio de la carrera de escape Te1, Te2 en base al período de pulsos de manivela generados por un sensor de ángulo de calado 2. Una sección de cálculo de masa de aire de admisión 4 calcula la masa deaire de admisión usando la ecuación como "Masa de aire de admisión A [{(1/Tc1)2-(1/Tc2)2}-{(1/Te1)2-(1/Te2)2}]". La masa de aire de admisión calculada se introduce en una sección de cálculo de cantidad de inyección de combustible 5, que calcula lacantidad de inyección de combustible correspondiente a la masa de aire de admisión según una relación objetivo de aire de combustible. Una válvula de inyección de combustible 16 es movida a un ciclo de trabajo determinado según la cantidad deinyección de combustible calculada, para suministrar una cantidad apropiada de combustible al motor 1.Be able to calculate the amount of fuel injection by detecting the mass of intake air without using an air flow meter. A compression and escape time calculation section 3 calculates respectively the start and end times of the compression stroke Tc1 and Tc2 and the start times of the escape stroke Te1, Te2 based on the period of crank pulses generated by a sensor of draft angle 2. An intake air mass calculation section 4 calculates the intake air mass using the equation as "Intake air mass A [{(1 / Tc1) 2- (1 / Tc2) 2} - {(1 / Te1) 2- (1 / Te2) 2}] ". The calculated intake air mass is entered in a fuel injection quantity calculation section 5, which calculates the amount of fuel injection corresponding to the intake air mass according to an objective fuel air ratio. A fuel injection valve 16 is moved to a determined duty cycle according to the calculated fuel injection amount, to supply an appropriate amount of fuel to the engine 1.
