摘要: A method of operating an engine with dual fuel injection capabilities to enable rail over-pressure control is shown. The comprises cylinder only port injection, while selectively activating and deactivating a direct injector in response estimated minimum mass from the injector. Direct actuated until injected by has reached lower threshold that above NVH limit engine.
