Abstract

"DISPOSITIVO DE CONTROLE DE INJEçãO DE COMBUSTìVEL". A presente invenção refere-se à permissão do cálculo de um tempo de injeção de combustível (Ti) com base em uma pressão atmosférica PA e uma pressão negativa de entrada PB sem utilizar um sensor de PA (atmosférico) e um sensor de PB (pressão negativa de entrada). Uma parte de operação aritmética básica (60) detecta os intervalos dos pulsos PLS nas regiões determinadas respectivamente em um curso de exaustão, em um curso de entrada, em um curso de compressão e em um curso de combustão de um motor em resposta aos pulsos PLS de um pulsador de manivela (1) e calcula os valores de flutuação de rotação do motor. Os valores de flutuação de rotação entre as regiões dos cursos respectivos do motor, e de uma pressão atmosférica PA, e de uma pressão negativa de entrada PB, possuem uma correlação um com o outro. Uma parte (65) de operação aritmética de previsão de PA e uma parte (66) de operação aritmética de previsão de PB são fornecidas para baixa rotação e alta rotação respectivamente. As partes de operação aritmética respectivas 65, 66 calculam a pressão atmosférica PA e a pressão negativa de entrada PB utilizando os valores de flutuação de rotação calculados pela parte de operação aritmética básica (60) nas fórmulas experimentais."FUEL INJECTION CONTROL DEVICE". The present invention relates to the allowance of calculating a fuel injection time (Ti) based on an atmospheric pressure PA and a negative inlet pressure PB without using an PA (atmospheric) sensor and a PB (pressure) sensor. negative input). A basic arithmetic operating part (60) detects the PLS pulse intervals in the regions determined respectively on an exhaust stroke, an input stroke, a compression stroke, and a combustion stroke of an engine in response to PLS pulses. crank pulsator (1) and calculates the engine's fluctuation values. The values of rotation fluctuation between the respective engine stroke regions, and an atmospheric pressure PA, and a negative inlet pressure PB, correlate with each other. A BP prediction arithmetic operation part (65) and a BP prediction arithmetic operation part (66) are provided for low rotation and high rotation respectively. The respective arithmetic operating parts 65, 66 calculate atmospheric pressure PA and negative inlet pressure PB using the rotational fluctuation values calculated by the basic arithmetic operating part (60) in the experimental formulas.
