<p>PURPOSE: To prevent pressure fluctuation of fuel even if fuel injection periods partly overlap by grouping the respective injectors in such a manner that the fuel injection periods do not overlap, and respectively connecting the same to the respective fuel supply passages. CONSTITUTION: An injector control means 30 sets fuel oil consumption according to the engine characteristic to operate an injector 15a. Whereupon, a fuel supply passage 10 is communicated with a fuel injection passage to inject gaseous fuel into a manifold 4a. Though the pressure of gaseous fuel in the fuel supply passage 10 is temporarily lowered by the above injection, as an injector 15c which is the next to inject fuel into a manifold 4c is supplied with gaseous fuel through the fuel supply passage 11, the injector 15c injects fuel with proper fuel pressure. Further, fuel injection to the next manifold 4d is not influenced by lowering of pressure because after the interior of the fuel passage 10 returns to designated pressure on the completion of fuel injection to the manifold 4a, fuel is injected. So with the manifold 4b.</p> |
