PURPOSE:To prevent the generation of black smoke at the time of acceleration of an engine without reducing the starting characteristic of the engine by a method wherein a diaphragm is provided within an open air chamber of the boost compensator for correcting the amount of fuel injection so that the diaphragm has a dashpot function. CONSTITUTION:The second diaphragm 12 is provided within the open air chamber 7 of the boost compensator, a push rod 14 is fixed to the second diaphragm and one end of the push rod is brought into contact with the first diaphragm 5 while the other end is passed through a casing 19 leaving a clearance 15 from the latter so as to come into engagement with an arm 17 for refulating the fuel increasing direction of a control rack 3. When a boost pressure acts on the second diaphragm 12 suddenly, the downward displacement of the second diaphragm 12 is controlled by a return spring 13 and the choking action of the clearance 15. |
