Abstract

a cabeça de cilindro (204) de um motor de combustão interna (101) compreende duas válvulas de admissão, a saber, a válvula de admissão de mistura (308), e a válvula de admissão de rolamento operando dentro de uma porta de mistura (501) e uma porta de rolamento (502). a carga é espirrada através de uma válvula de injeção de combustível (301) para dentro da porta de mistura e a porta de rolamento, respectivamente. uma área de mistura (620) é facilitada pela posição da válvula de injeção de combustível, onde o spray de combustível é esguichado para dentro da área de mistura (620) em direção à porta de mistura e a porta de rolamento. a relação de distância vertical (a) a partir de entre o ponto de spray de combustível (p) e a base da extremidade de porta (y-y) e a largura transversal (e, f) de pelo menos uma das duas portas de entrada é entre 1.5 e 3. a presente invenção fornece uma entrada de carga a partir de ambas as porta de mistura e porta de rolamento para assegurar a distribuição de carga adequada e evitar um barulho indesejado do motor.the cylinder head (204) of an internal combustion engine (101) comprises two inlet valves, namely, the mixing inlet valve (308), and the rolling inlet valve operating within a mixing port ( 501) and a rolling door (502). the load is splashed through a fuel injection valve (301) into the mixing port and the rolling port, respectively. a mixing area (620) is facilitated by the position of the fuel injection valve, where the fuel spray is squirted into the mixing area (620) towards the mixing port and the rolling port. the vertical distance ratio (a) from between the fuel spray point (p) and the base of the door end (yy) and the transverse width (e, f) of at least one of the two entrance doors is between 1.5 and 3. the present invention provides a load input from both the mixing port and the rolling port to ensure proper load distribution and avoid unwanted engine noise.
