PURPOSE:To prevent generation of black smoke and noise at the time of starting under a normal temperature, by controlling interlocking between a starter switch and a fuel increasing device at the time of starting according to an engine temperature or an engine speed, in a device actuating the fuel increasing device at the time of starting by interlocking it with a starter switch. CONSTITUTION:Although an output of an engine temperature responding to switch 18 is either ''1'' or ''0'' in case an engine speed is less than a specific value at the time of starting under either a low or a normal temperature of an engine, a solenoid directional control valve 10 is excited through an OR circuit 16 as an output of an engine speed responding to switch 17 is ''1'' and an output port 10a and an input port 10c are connected with each other. In this instance, when an input port 13c and an output port 13a are connected by exciting a solenoid directional control valve 13 through an output signal of a starter switch 19 with each other, negative pressure from a negative pressure source 15 is fed to a diaphragm chamber 5. A diaphragm 3, therefore, is moved to the left against a spring 6 and a control rack 2 of an injection pump 1 is moved to a fuel quantity increasing position X2. |
