摘要： A control module for a vehicle includes a correction module that generates a correction signal based on a regeneration state of an exhaust system of the vehicle and based on a received environmental signal. The environmental signal includes at least one of an altitude value, an ambient temperature, and an air flow value. The air flow value corresponds to air flow across an external area of the exhaust system. A first post injection module generates a first post injection signal. A second post injection module adjusts the first post injection signal based on the correction signal to generate a second post injection signal.

摘要： A method unloads hydrocarbon emissions deposited by an exhaust gas on an after-treatment device that is employed in an exhaust system for an internal combustion engine. The method includes determining whether the engine has been operating at a preset idle speed for a predetermined amount of time. The method also includes increasing the preset idle speed by a predetermined value if the engine has been operating at a preset idle speed for a predetermined amount of time. The increasing of the engine idle speed increases a flow rate of the exhaust gas to the after-treatment device and unloads the deposited hydrocarbon emissions. A system for unloading hydrocarbon emissions deposited on an after-treatment device and a vehicle employing such a system are also disclosed.

摘要： A fuel control system for a vehicle comprises a fuel control module, a heat release determination module, and a detection module. The fuel control module supplies fuel to a cylinder of a diesel engine for combustion within the cylinder. The heat release determination module determines a heat release value based on a pressure within the cylinder during the combustion. The detection module selectively indicates that the fuel is a diesel fuel alternative when the heat release value is less than a predetermined heat release value. The predetermined heat release value is less than a second predetermined heat release value associated with diesel fuel.
