Abstract
DISPOSITIVO DE ADMISSÃO DE MOTOR DE COMBUSTÃO INTERNA PARA VEÍCULO DO TIPO PARA CONDUZIR MONTADO EM SELIM. Dispositivo de admissão que em um motor de combustão interna para veículo do tipo para conduzir montado em selim incluindo uma válvula borboleta, uma válvula de controle de tumble e uma passagem de tumble fornecida em uma passagem de admissão de ar, garante o abastecimento de ar de admissão na passagem de tumble e aumenta uma velocidade do ar de admissão. A válvula borboleta é fornecida em uma passagem de admissão de ar de um motor de combustão interna, esta é controlada a qualquer determinado grau de abertura para controlar um volume de ar de admissão, e a válvula de controle de tumble está a jusante com relação à válvula borboleta e controla o abastecimento de ar de admissão em uma passagem principal da passagem de admissão de ar dividida em passagem principal e passagem de tumble que tem a seção transversal em um lado da extremidade a jusante que é demarcado pela parede divisória de um formato arqueado em uma seção transversal circular até uma extremidade a jusante, e tem uma seção transversal em uma extremidade a montante que é maior do que a área da seção transversal no lado da extremidade a jusante e demarcada pela parede divisória de um formato linear em um formato semicircular tendo um diâmetro máximo maior do que o diâmetro da seção transversal circular. A passagem de admissão de ar inclui uma parede divisória dividindo o interior da passagem de admissão de ar em duas áreas.INTERNAL COMBUSTION ENGINE INLET DEVICE FOR SADDLE MOUNTED DRIVING TYPE VEHICLE. Inlet device which in a saddle-mounted drive-type vehicle internal combustion engine including a butterfly valve, a tumble control valve and a tumble port provided in an air inlet port, ensures the air supply of inlet in the tumble passage and increases an inlet air velocity. The butterfly valve is provided in an air intake port of an internal combustion engine, this is controlled to any given degree of opening to control an intake air volume, and the tumble control valve is downstream of the valve. butterfly valve and controls the intake air supply in a main passage of the air intake passage divided into main passage and tumble passage which has the cross section on one side of the downstream end which is demarcated by the dividing wall of an arched shape in a circular cross section to a downstream end, and has a cross section at an upstream end that is greater than the cross sectional area on the downstream end side and demarcated by the dividing wall from a linear shape to a semicircular shape having a maximum diameter greater than the diameter of the circular cross section. The air inlet passage includes a partition wall dividing the interior of the air inlet passage into two areas.
