For this purpose and diesel-electric hybrid drive strands emissions test

摘要

By means of the present invention are diesel-electric hybrid drive strands and method for operating and testing of such drive trains is made available. Certain exemplary embodiments, the test and certification procedure -, in which a controller according to predetermined duty cycle criteria a diesel engine alone, an integrated motor / generator alone or both the diesel engine as well as the motor / generator operates a braking torque, in order to provide on a common output shaft. Emissions are based on criteria is measured which the effects of a regenerative braking operation, a shut-off internal combustion engine and other operating modes be taken into account, which are specific for hybrid-drive strands. Further exemplary embodiments, hybrid powertrain systems and method for operating the same in order to fulfil of power and emission requirements, including respective limit values for no_x-, Hydrocarbon, fine dust-, co and co₂-Emissions, without that conventional devices, or techniques for reducing emissions are required.
