Abstract

método e sistema para controlar a quantidade de injeção de combustível em motor de combustível etanol-flexível. método para controlar a quantidade de injeção de combustível de um motor alimentado a combustível de etanol-flexível. o método compreendendo: coletar a quantidade de entrada de ar de um coletor de admissão de ar do motor; coletar uma velocidade do motor e a temperatura do líquido de arrefecimento do motor para obter uma razão alvo de ar/combustível, analisando uma tabela; calcular a quantidade de evaporação de combustível de operação em um processo de operação do motor de acordo com um período predefinido; calcular uma quantidade alvo de injeção de combustível do motor de acordo com a quantidade de admissão de ar, a razão alvo de ar-combustível e a quantidade de evaporação de combustível na operação; e controlar a injeção de combustível do motor de acordo com a quantidade alvo de injeção de combustível. é também proporcionado um sistema para controlar a quantidade de injeção de combustível de um motor alimentado com combustível flexível de etanol. por meio do método e sistema para controlar a quantidade de injeção de combustível de um motor alimentado com combustível flexível de etanol, a quantidade de injeção de combustível alvo do motor pode ser calculada com precisão de acordo com a quantidade na operação de evaporação de combustível no processo de operação do motor.method and system for controlling the amount of fuel injection in an ethanol-flexible fuel engine. method for controlling the fuel injection amount of a flexible ethanol-fueled engine. the method comprising: collecting the amount of air intake from an engine air intake manifold; collect an engine speed and engine coolant temperature to obtain a target air / fuel ratio by analyzing a table; calculate the amount of fuel evaporation operating in an engine operation process over a predefined period; calculate an engine fuel injection target amount according to the amount of air intake, the target air-fuel ratio, and the amount of fuel evaporation at operation; and control the engine fuel injection according to the target amount of fuel injection. Also provided is a system for controlling the fuel injection amount of a flexible ethanol fueled engine. Through the method and system for controlling the fuel injection amount of a flexible ethanol fueled engine, the target fuel injection amount of the engine can be accurately calculated according to the amount of fuel evaporation operation in the engine operation process.
