Nonlinear model predictive control applied to multivariable thermal and chemical control of selective catalytic reduction aftertreatment

Autor: Anthony Truscott, Dina Shona Laila, Peter Fussey, Jonathan Sowman, Andrew Cruden

Publikováno v: International Journal of Engine Research. 20:1017-1024

Manufacturers of diesel engines are under increasing pressure to meet progressively stricter NO x emission limits. A key NO x abatement technology is selective catalytic reduction in which ammonia, aided by a catalyst, reacts with NO x in the exhaust

Despite the continuously tightening emissions legislation, urban concentrations of nitrogen oxides (NO x ) remain at harmful levels. Road transport is responsible for a large fraction, wherein diesel engines are the principal culprits. Turbocharged d

Nonlinear Model Predictive Control for Cold Start Selective Catalytic Reduction

Autor: Jonathan Sowman, Andrew Cruden, Peter Fussey, Dina Shona Laila

Publikováno v: IFAC-PapersOnLine. 48:471-476

Selective catalytic reduction (SCR) is emerging as a key technology for reducing emissions of nitrogen oxides (NOx) from diesel vehicles, but the temperature dependence of the governing chemical kinetics are highly nonlinear and industry standard tec

Selective catalytic reduction (SCR) continues to be the preferred technology for abatement of oxides of nitrogen (NO x ) from diesel engines, yet challenges remain to bring SCR efficiency up to the level required by legislation. Such efficiency gains

Design of digital testbeds for undergraduate microelectronics teaching

Autor: Jeffrey Hooker, Jonathan Sowman, Matthew Brejza, Robert G. Maunder, David Oakley

Publikováno v: EWME

In this paper we detail the series of digital microelectronics testbed boards which have been developed to meet the requirements of the microelectronics undergraduate programmes at the University of Southampton. We discuss how our boards solve many o

A predictive control approach to diesel Selective Catalytic Reduction

Autor: Dina Shona Laila, Peter Fussey, Jonathan Sowman, Andrew Cruden, Anthony Truscott

Publikováno v: ECC

Reduction of oxides of nitrogen (NO x ) emitted from diesel exhaust systems is a current problem due to increased stringency in worldwide emissions legislation. One of the most successful approaches to reduce tailpipe NO x is to reduce NO x by ammoni
