摘要： A method for determining a temperature of a diaphragm of a pump, the pump pumping a fluid out of a tank to a dispersion point by way of a movement of the diaphragm, the pump being fastened to the tank, the temperature of the diaphragm being estimated in a manner which is at least dependent on the temperature of the fluid in the tank.

摘要： The present disclosure relates to engines for a motor vehicle and some embodiments include a method for operating an exhaust train of a motor vehicle engine including: measuring a particle concentration downstream of a particle filter at a first operating point; determining the filter efficiency at the first operating point; changing operation of the engine to a second operating point to increase the particle emissions; measuring the particle concentration downstream of the filter at the second operating point; determining the filter efficiency at the second operating point; determining a difference between the efficiency levels; detecting an offset error, if the difference exceeds a defined threshold; and identifying a particle sensor as defective if an offset error is detected, rather than identifying the particle filter as defective.
