Motor vehicle, particularly city-bus, with a dieselengine/generator unit

摘要

In a motor vehicle, the driven wheels are driven by electric motors (16, 18) which are fed via a current controller (8) by a generator (6) coupled to a diesel engine (4). In the exhaust duct of the diesel engine (4) there is a particle filter (30) which is heated electrically via a circuit breaker (22) coupled to the electric lead arrangement for the driving motors (16, 18). For this purpose, there are resistance heating elements in the filter material of the particle filter (30). Regeneration of the filter is preferably carried out during the braking phases of the vehicle. In these braking phases, the driving motors (16, 18) act as generators and the electrical energy supplied by them serves to heat the particle filter (30) and to drive the generator (6), which is then motor-driven. This generator then operates the diesel engine, the fuel supply having been shut off, and the diesel engine thus operates as a compressor, pumping fresh air into the particle filter (30) via the exhaust system.
