System and method for controlling operating frequency of a purge valve to improve fuel distribution

Abstract

A system according to the principles of the present disclosure includes an engine speed module and a valve control module. The engine speed module determines a speed of an engine based on a position of a crankshaft. The valve control module selectively adjusts an operating frequency of a purge valve based on the engine speed.

Description

technical field [0001] The present disclosure relates to internal combustion engines, and more particularly to systems and methods for controlling the frequency of operation of purge valves to improve fuel distribution to cylinders of the engine. Background technique [0002] The background description provided herein is for the purpose of generally presenting the context of the disclosure. The work of the presently named inventors (to the extent described in the Background section), and aspects of this description that are not otherwise considered prior art at the time of filing, are neither expressly nor implicitly admitted to be inconsistent with this disclosure existing technology. [0003] Internal combustion engines combust an air and fuel mixture within cylinders to drive pistons, which produces drive torque. Airflow into the engine is regulated via a throttle. More specifically, the throttle adjusts throttle area, which increases or decreases airflow into the engi...
