Abstract
This paper discusses the possibility of equipping Euro 3 and older vehicles with a universal retrofit kit to reduce the NOX and the PM emissions without producing any secondary effect.
Out of several configurations, the optimal setup for EGR and DPF regeneration was evaluated and tested on a passenger car engine testbench. Stationary results showed that with a low pressure EGR it was possible to reduce the NOX emissions by more than 50%, and the filtration efficiency of the DPF was greater than 99%.
After various dynamic tests on the test bench to improve the control algorithm, the system was designed to be installed on a garbage truck.
