Abstract
A system according to the principles of the present disclosure includes a fuel volatility module, a temperature generation module, and a fuel control module. The fuel volatility module estimates a volatility of fuel provided to an engine based on an engine torque and an engine speed. The temperature generation module generates a temperature of an intake valve of the engine. The fuel control module selectively increases an amount of fuel provided to the engine based on the temperature of the intake valve, the engine torque, and the fuel volatility.
