Abstract

"MOTORES DE COMBUSTãO INTERNA E CONTROLE". Motor de combustão interna compreendendo pelo menos uma câmara de combustão (20) com um injetor de distribuição (25) para injetar combustível diretamente na referida câmara de combustão, o referido motor ainda compreendendo pelo menos um duto de ar de entrada com válvula (46) para distribuição de ar de combustão na referida câmara de combustão, em que o referido duto de ar de entrada e/ou sua válvula (42) é disposto para produzir baixo movimento do rotação em cilindro do ar de entrada sendo distribuído na referida câmara de combustão, de modo a reduzir o empobrecimento excessivo de combustível em regiões finais de gás da referida câmara de combustão. O injetor de distribuição (25) é adaptado para distribuir combustível arrastado em um gás para a referida câmara de combustão e, em particular, é um injetor de combustível em cilindro direto auxiliado por gás adaptado para gerar uma carga estratificada dentro da referida câmara de combustão para combustão guiada por pulverização. O duto de ar de entrada com válvula é disposto para proporcionar uma rotação de ar de entrada em cilindro que seja menor do que cerca de 2,0 através de toda a faixa de valores de levantamento de válvula de orifício de entrada e, de preferência, menos do que 1,5 e, mais preferivelmente, cerca de 1,0 através de uma parte substancial de levantamento de válvula de entrada. O controle de estratificação do motor pode, desse modo, ser aperfeiçoado.
