摘要： An engine system according to the present invention includes an engine and a fuel system that delivers a liquid fuel and a vapor fuel to the engine. A control module communicates with the fuel system and modulates the vapor fuel delivered to said engine based on a determination of a desired vapor fuel rate and a maximum available vapor fuel rate of the fuel system. The control module determines the desired vapor rate based on a mass rate of liquid fuel being delivered to the engine and a coolant temperature of the engine. The control module determines a vapor density by estimating the vapor density based on a temperature of an intake manifold or alternatively receives a signal from a sensor.

The first module monitors at least one of (i) a temperature of a first catalyst of a catalyst assembly in an exhaust system of an engine and (ii) an active catalyst volume of the first catalyst. The mode selection module is configured to select an adsorber regeneration mode and generates a mode signal based on the at least one of the temperature and the active catalyst volume. The ARC module at least one of activates an air pump and cranks the engine to regenerate an adsorber of the catalyst assembly while the engine is deactivated based on the mode signal.

摘要： A start-stop system includes a fuel type module that determines a fuel type of a fuel supplied to an engine. A threshold module determines a first threshold based on the fuel type. A temperature module estimates a temperature of a catalyst of an exhaust system of the engine. A comparison module compares the temperature to the first threshold and generates a comparison signal. A power module adjusts power to a heating circuit based on the comparison signal. The heating circuit is configured to increase temperature of the catalyst. The power module adjusts the power to the heating circuit to increase the temperature of the catalyst when the engine is shutdown. An engine control module shuts down and restarts the engine to reduce idling time of the engine.
