摘要： A vehicle biodiesel fuel diagnostic method may include determining a biodiesel fuel concentration of fuel added to a vehicle fuel tank during a fueling event at a fueling location and determining the fueling location. The biodiesel fuel concentration and fueling location may be transmitted to an information system where the concentration and location are stored in a database. The method may further include indicating an abnormal biodiesel fuel condition in the database when the biodiesel fuel concentration is outside of a predetermined range.

摘要： A system for a vehicle includes a triggering module and a cylinder control module. The triggering module generates a trigger when a catalyst temperature is greater than a predetermined temperature. In response to the generation of the trigger, the cylinder control module: disables opening of an exhaust valve of a cylinder for an exhaust phase of a first combustion cycle of the cylinder; disables opening of the exhaust valve for N combustion cycles of the cylinder that follow the first combustion cycle; and enables opening of the exhaust valve for a second combustion cycle that follows the N combustion cycles. N is an integer greater than zero.
