摘要： The diagnosis of the heating of a catalytic converter situated in an exhaust system of an internal combustion engine is described. The system includes monitoring the actual ignition angle intervention. A current ignition angle is acquired over a specified time and converted into a torque model used for catalytic converter heating. Using the torque model, a degree of fulfillment of executed catalytic converter heating measures is obtained and an error signal is generated by comparing the obtained degree of fulfillment to a limiting value.

摘要： The handheld hair dryer for generating a heated air stream has a blower for generating an air stream, an electric heater for heating the air stream, a catalytic odor filter for deodorizing the air stream and a thermal radiator for heating the catalytic odor filter. The electric heater and the catalytic odor filter are separate from each other so that the active surface area of the catalytic odor filter can be maximized to deodorize the air stream. The thermal radiator is also separate from the electric heater.
