Design and rapid prototyping of a closed-loop control strategy of the injected mass for the reduction of CO2, combustion noise and pollutant emissions in diesel engines

Preliminary simulation tests, performed with a 1D code on a diesel engine for light duty commercial vehicles, have proved that the new technology could lead to important reductions in the CO2 engine out emissions (3%) and in the combustion noise (up to 0.5 dBA). Significant percentage improvements in NOx (3%) and soot (6%) engine out emissions have also been found.
