l probes in turbocharged diesel engines are usually located downstream of the turbine, exhibiting a good dynamic
response but a significant delay because of the exhaust line transport and the hardware itself. With the ...

No-x estimation in diesel engines is an up-to-date problem but still some issues need to be solved. Raw sensor signals are not fast enough for real-time use while control-oriented models suffer from drift and aging. A ...
Look-up tables are commonly used in the automotive field for handling operating point variations. However, constant maps cannot cope with systems variations and ageing. Methods, such as Kalman filter or Extended Kalman ...
There are many approaches addressing the problem of optimal energy management in hybrid electric vehicles; however, most of them optimise the control strategy for particular driving cycles. This paper takes into account ...

[ES] La sociedad está cada vez mas concienciada con el medio ambiente y los problemas asociados. Los avances en la Industria automovilística no deben buscar únicamente la mejora de las prestaciones de los vehículos, sino ...
An on-engine method for dynamic characterisation of automotive NOx concentration sensors is presented. Steps in start of injection on a diesel engine are employed to achieve step-like NOx concentration variations on exhaust ...
The development of one cycle resolution control strategies and the research at HCCI engines demands an accurate estimation of the trapped mass. In contrast to current methods for determining the mass flow, which are only ...
The implantation of nitrogen oxide sensors in diesel engines was proposed in order to track the emissions at the engine exhaust, with applications to the control and diagnosis of the after-treatment devices. However, the ...
The implantation of nitrogen oxide sensors in diesel engines is necessary in order to track emissions at the engine exhaust line for diagnosis and control of the after-treatment devices. However, the use of models is still ...
[EN] This report documents the experimental characterisation and setting-up of a cleanroom
that has been built at the von Karman Institute. It is a required process that will
allow researchers to operate the facility for ...
