Abstract

"MOTOR DE DOIS TEMPOS COM INJEçãO DIRETA". Motor de dois tempos que compreende uma câmara de combustão, um cilindro (6) dotado de uma abertura de escapamento (9) na qual está centrado um primeiro plano diametral do cilindro, um pistão (4), um cabeçote (10) dotado de uma vela (11) situada do lado da abertura de escapamento em relação a um segundo plano diametral (P2-P2) perpendicular ao primeiro, e de um injetor (20) adaptado para pulverizar um jato de combustível na câmara de combustão, que está situado do outro lado do segundo plano diametral, e o eixo de pulverização (P) forma um ângulo (X compreendido entre 30<198> e 70<198> a partir de um plano transversal (T-T) do cilindro, e um ângulo <225> compreendido entre + 45<198> e -45<198> a partir do primeiro plano diametral. O ângulo de abertura <sym> do jato está compreendido entre 15<198> e 75<198>, a injeção do combustível começa quando o virabrequim (3) está entre 45<198> e 20<198> antes do fechamento da abertura de escapamento (9), a pressão de injeção e a orientação do eixo de pulverização são determinadas em função da circulação dos gases para obter uma mistura ar/combustível estequiométrica na região da vela no momento da ignição.
