Abstract
Official abstract text for this publication.
Methods and systems are described for controlling fuel injection in an engine equipped with a dual injector system including a port injector and a direct injector. A ratio of port injected fuel to direct injected fuel is adjusted based at least on intake valve temperature. The proportion of fuel port injected into a cylinder is increased as the intake valve temperature for the given cylinder increases to improve fuel vaporization in the intake port.
First claim
Opening claim text (preview).
1 . A method for an engine, comprising: adjusting a ratio of fuel delivered to a cylinder via direct injection relative to port injection based on a temperature of an intake valve of the cylinder. 2 . The method of claim 1 , wherein the adjusting includes increasing the ratio of fuel delivered to the cylinder via port injection while correspondingly decreasing the ratio of fuel delivered via direct injection as the intake valve temperature of the cylinder increases.…
