Abstract

"APARELHO E MéTODO PARA DETECTAR PRESSãO ATMOSFéRICA PARA MOTOR DE 4-TEMPOS". Trata-se de um dispositivo de detecção de pressão atmosférica de um motor de quatro tempos e um método para detectar a pressão atmosférica capaz de detectar precisamente a pressão atmosférica sem usar um sensor de pressao atmosférica, o método compreendendo as etapas de detectar uma pressão de entrada, e calcular a pressão atmosférica usando a pressão de entrada imediatamente antes da abertura de uma válvula de entrada quando uma carga de motor é pequena e a velocidade do motor entra em uma faixa de velocidade especificada desde que, quando a carga de motor é grande ou dependendo da velocidade do motor, a pressão de entrada é instável imediatamente antes da abertura da válvula de entrada.
