G. E. Brownission limit is reduced to the ambitious long-term target of 95 g/km from 2020. Additionally, the average CO. emission limit for new light-duty commercial vehicles is 175 g/km from 2014 (70% manufactured vehicles) to 2017 (100%); and it is reduced to 147 g/km (ambitious long-term target) from 2020.

T. J. Mazurek,J. Cooperstein,S. Kahanaficult or impossible to take all of them into account in the rotordynamic computation where only the rotor containing the compressor, turbine wheels, rotor shaft, radial bearings, and seal rings is considered. The boundary conditions are generally assumed ideal in the computation, such as sufficient

J. R. Bond,W. D. Arnett,B. J. Carrdius, constitutes a classic subject of machine design. Nevertheless attention is limited to rotor profiles for which governing equations are solvable in closed form. Furthermore very few actual engineering issues may relate to structures for which stress and strain analysis in the linear elastic fie
