Abstract
A system ( ) and method for controlling the injection of fuel into a cylinder ( ) of an internal combustion engine ( ) are provided. The system ( ) includes a fuel injector ( ), a temperature sensor ( ), and an electronic control unit (ECU) ( ). The fuel is parsed into a plurality of components based on the boiling points of elements of the fuel. ECU ( ) stores mass fraction values for each component relative to the total mass of a sample of the fuel along with vaporization rates for each component. These values are used by the ECU ( ) to account for different vaporization rates among fuel elements. In accordance with the invention, ECU ( ) is further configured to adjust the mass fraction values responsive to the combustion air-fuel ratio and the engine temperature to account for the different volatility characteristics of various fuels.
