Abstract

"DISPOSITIVO DE CONTROLE DE MOTOR DE 4 TEMPOS E MéTODO DE CONTROLE". O controle é efetuado verificando a pressão atmosférica a partir da pressão de admissão imediatamente antes do tempo de admissão, calculando a partir da pressão atmosférica, pressão de entrega da bomba e pressão de admissão, uma pressão de injeção do combustível (P) consistindo da diferença de pressão entre a pressão do combustível alimentado para o injetor (13) e a pressão de admissão, que é a atmosfera da injeção, calculando um coeficiente de injeção do combustível (Q~ t~) dividindo o coeficiente do tempo de injeção do combustível (Q~ to~) pela massa unitária medida no momento da pressão de injeção do combustível (P~ o~) que forma uma referência pela raiz quadrada (P^ 1/2^) da pressão de injeção do combustível, e calcular, pelo uso desse coeficiente de injeção de combustível (Q~ t~), o tempo de injeção de combustível para injetar a quantidade de injeção de combustível exigida para atingir uma razão desejada de ar-combustível. Isso torna altamente preciso o controle do tempo de injeção do combustível quando um regulador para controlar o limite superior da pressão da entrega da bomba de combustível é instalado no lado do tanque de combustível.
