Abstract
Official abstract text for this publication.
A method and system for improving starting of an engine is presented. In one example, the method selects a first cylinder to receive fuel since engine stop based on intake valve closing time. The method also describes selecting the first cylinder to receive fuel since engine stop based on an end of fuel injection time.
First claim
Opening claim text (preview).
The invention claimed is: 1. An engine system, comprising: an engine including a cylinder; a port fuel injector positioned to supply fuel to the cylinder; and a controller including non-transitory instructions for selecting a cylinder for a first combustion event in the cylinder since engine stop in response to an end of fuel injection timing and an intake valve closing time. 2. The engine system of claim 1 , where the end of fuel injection timing is bas…
