SYSTEM AND METHOD FOR DETERMINING THE REID VAPOR PRESSURE OF FUEL COMBUSTED BY AN ENGINE AND FOR CONTROLLING FUEL DELIVERY TO CYLINDERS OF THE ENGINE BASED ON THE REID VAPOR PRESSURE

摘要

A system according to the principles of the present disclosure includes a Reid vapor pressure (RVP) module and a fuel control module. The RVP module determines a Reid vapor pressure of fuel combusted by an engine based on a hydrocarbon concentration measured by a hydrocarbon sensor disposed in a fuel system of the engine. The fuel control module controls at least one of a fuel injector of the engine, a purge valve in an evaporative emissions (EVAP) system of the engine, and a vent valve in the EVAP system of the engine to adjust an amount of fuel delivered to cylinders of the engine based on the Reid vapor pressure.
