Abstract

"CONTROLADOR DE INJEçãO DE COMBUSTìVEL". Um dispositivo de controle de injeção de combustível permitindo calcular uma quantidade de injeção de combustível por detecção da massa de ar admitido sem usar um medidor de fluxo de ar, em que uma parte de cálculo de tempo de compressão e de escapamento (3) calcula os tempos de início e de fim do curso de compressão (Tc 1) e (Tc2) e os tempos de início e de fim do curso de escapamento (Te1) e (Te2) com base no ciclo de pulsos da manivela gerados por um sensor do ângulo de manivela (2), uma parte de cálculo de massa de ar admitido (4) calcula uma massa de ar admitido por uso de uma massa de ar admitido <sym> [{(1/Tc1)^ 2^ - (1/Tc2)^ 2^} _ {(1/Tel)^ 2^ (1/Te2)^ 2^}], sendo a massa calculada de ar admitido introduzida, como dado de entrada, em uma parte de cálculo da quantidade de injeção de combustivel (5), de modo a calcular a quantidade de injeção de combustível para a massa de ar admitido de acordo com uma relação alvo ar/combustível, e uma válvula de injeção de combustível (1b) é acionada em uma carga determinada de acordo com a quantidade calculada de injeção de combustível de modo a suprir um motor com a quantidade correta de combustível (1)."FUEL INJECTION CONTROLLER". A fuel injection control device allowing to calculate a fuel injection amount by sensing the admitted air mass without using an air flow meter, where a compression and exhaust time calculation part (3) calculates the compression stroke start and stop times (Tc 1) and (Tc2) and exhaust stroke start and end times (Te1) and (Te2) based on the crank pulse cycle generated by a torque sensor crank angle (2), an allowable air mass calculation part (4) calculates an allowable air mass using an allowable air mass <sym> [{(1 / Tc1) ^ 2 ^ - (1 / Tc2) ^ 2 ^} _ {(1 / Tel) ^ 2 ^ (1 / Te2) ^ 2 ^}], where the calculated mass of admitted air is entered as input into a calculation portion of the injection quantity (5) to calculate the amount of fuel injection for the allowable air mass according to a target air / fuel ratio, and a fuel injection valve. the fuel (1b) is operated in a load determined according to the calculated amount of fuel injection in order to supply an engine with the correct fuel quantity (1).
