ENGINE STARTUP FUEL PRESSURE CONTROL SYSTEMS AND METHODS
First Claim
1. A fuel pressure control system for a vehicle, comprising:
- a pressure regulator module that regulates a fuel pressure supplied to an engine to a first predetermined pressure during an engine running period; and
a pressure increasing module that selectively increases said fuel pressure to a second predetermined pressure during said engine running period when a counter value is one of greater than and less than a predetermined final value,wherein said second predetermined pressure is greater than said first predetermined pressure, andwherein said counter value is set to said predetermined final value after said engine is started for a first time after being assembled.

Abstract
A fuel pressure control system for a vehicle comprises a pressure regulator module and a pressure increasing module. The pressure regulator module regulates a fuel pressure supplied to an engine to a first predetermined pressure during an engine running period. The pressure increasing module selectively increases the fuel pressure to a second predetermined pressure during the engine running period when a counter value is one of greater than and less than a predetermined final value. The second predetermined pressure is greater than the first predetermined pressure, and the counter value is set to the predetermined final value after the engine is started for a first time after being assembled.
