Abstract

PURPOSE:To prevent generation of smoke in accordance with a feed of excessive fuel at acceleration, by determining an injection amount characteristic with a link lever device, displacing a supporting point of the link lever device through a cam mechanism and interlocking said cam mechanism to an accelerator. CONSTITUTION:A control sleeve 16 opens and closes a cutoff port 15 to control an injection amount of fuel, and a link lever device 19, displacing the control sleeve 16, is provided. A cam mechanism 30, displacing a supporting point A determining an injection amount characteristic, is provided and interlocked to an accelerator. At high load operation, the supporting point A is displaced to the excess fuel direction. A governor characteristic is adjusted by a load adjusting screw 26 at medium and low load operation, and adjusted by a cam 30 at high load operation. In this way, a fuel injection amount can be fully fed at high load operatin to prevent waste of fuel at low and medium load operation. Further an excessive amount of fuel is not injected at acceleration, and generation of smoke can be prevented.
