Hydraulics still in control of off-highway
needs
Engineers continue to master electronic controllers and software to
help systems manage engine speeds and boost efficiency, to the
ultimate benefit of both OEMs and end-users.
Off-highway calibration challenges-big and
complex
As the final set of Tier 4 regulations kick in for engines greater
than 750 hp (560 kW), calibration efforts must contend with complex
engine and aftertreatment systems. Engine manufacturers and service
providers deal with this complexity, but does it need to be
so?
DEF delivery modelling for SCR systems
Researchers characterize a 0-D model of a urea delivery module,
oriented to model-based control and to the simulation of the system
response to fault injections finalized to diagnosis
validation.
Development trends for heavy engines
Downsizing engine displacement, new materials, friction reduction,
and advanced boosting and fuel-injection technologies have
demonstrated potential in light-duty vehicles, and implementation
is under way. FEV experts provide an outlook of how these
technologies can improve the base engine for commercial
applications with regard to future emissions and fuel-efficiency
requirements.
