Claims

[Scope of utility model registration request]

In the accumulator fuel system of an internal combustion engine, funk and
A function cam guide into which the John cam is slidably inserted and one end is pin-coupled to the box body, has a roller groove formed in a shape that corresponds to the optimal injection timing for each load of the engine, and is linked to the engine output. A function cam connected to the link, a function lever that uses the pin as a fulcrum as a fulcrum and swings a timing adjustment shaft at the other end by a roller guided by the roller groove at one end and linked to movement of the function cam, and a fuel control lever. a timing adjustment arm that adjusts the injection timing by moving a roller that contacts the cam and sets the injection timing in conjunction with the timing adjustment shaft; and a timing adjustment arm that adjusts the injection timing by moving a roller that comes into contact with the cam and sets the injection timing; A fuel injection timing adjustment device comprising: a timing adjustment lever for changing the injection timing by moving the roller position of the function lever;
