摘要：
A system according to the present disclosure includes a pump operating parameter module and a purge flow control module. The pump operating parameter module determines a value of an operating parameter of a purge pump that delivers purge fluid from a canister in an evaporative emissions system to an intake system of an engine. The operating parameter of the purge pump includes at least one of a speed of the purge pump, an amount of current supplied to the purge pump, and an amount of power supplied to the purge pump. The purge flow control module controls at least one of a purge valve and the purge pump to adjust an amount of purge fluid delivered to a cylinder of an engine based on the determined value of the operating parameter of the purge pump.
