PURPOSE:To control automatically an ignition time accurately for full operation range by controlling an actuating mechanism for a breaker plate of a distributor provided with a centrifugal angle leading mechanism correlatively with a fuel supply pressure to a fuel injection nozzle. CONSTITUTION:Ignition time of an engine is controlled in the leading direction by a centrifugal angle leading mechanism 25 of a distributor 23 in accordance as a rotational speed increases. However, in a domain where opening of a throttle valve 8 is small, a turbosupercharger 4 rotates slowly and a suction pressure is low, therefore a fuel supply pressure in a fuel supply passage 15 correlating therewith is low. A low pressure works in a diaphragm chamber of a diaphragm actuating mechanism 31, consequently, and a breaker plate 28 rotates in the leading direction. Then, when supercharging is kept on, said fuel supply pressure gets high, and the breaker plate 28 rotates in the lagging direction through the diaphragm actuating mechanism 31. |
