Abstract:
A fuel limitation device for an engine with a supercharger comprising:a fuel meter (21) of a fuel injection pump (20) for the engine (E) with the supercharger, which is made movable for fuel metering through a governor lever (14); and a swing lever (31) supported by a pivot axis (Q) and having a power input point (J) which engages with an output rod (30) of a diaphragm-type boost actuator (26), the swing lever (31) having a power output point (K) faced to the fuel meter (21) from a fuel increase side (R) of the fuel meter (21), if the boost actuator (26) operates in response to a delayed rise of a pressure (P) supercharged to the engine (E), the power output point (K) of the swing lever (31) inhibiting the fuel meter (21) form moving for fuel increase, wherein the governor lever (14) has an output portion (17) connectably and separably opposed to the fuel meter (21) from the fuel increase side (R) and a start spring (18) urges the fuel meter (21) toward a starting fuel increase side, an actuator (40) displacing the pivot axis (Q) to position the power output point (K) of the swing lever (31) on the fuel increase side (R) or a fuel decrease side (L), when making a cold start of the engine, the power output point (K) positioned on the fuel increase side receiving the fuel meter (21) at a starting fuel increase position (St) and when making a warm start of the engine, the power output point (K) positioned on the fuel decrease side (L) receiving the fuel meter (21) at a starting fuel decrease position (Ls).
