FUEL SUPPLY DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To atomize fuel in a fuel supply device of an internal combustion engine. SOLUTION: A center of a large nozzle hole 12 is arranged on the side of an air intake passage center O2 from a horizontal line L4 passing a center of gravity O4 of a triangle connecting each of centers of three nozzle holes 11A, 11B, 12 and a straight line S4 passing this center of gravity O4 of the triangle and it is set so that an absolute value of an angle θ1 that a straight S4 passing this center of gravity O4 of the triangle and the center of the large nozzle hole 12 is inclined to a horizontal line L4 comes to be roughly equal to an absolute value of an angle θ2 that a straight line S8 passing the air intake passage center O2 and a center of gravity O8 of an opening part 8 of a swirl control valve 6 is inclined to a horizontal line L2 .
