MICO/BOSCH are providing high sophisticated diesel injection systems being essential for lowest raw emissions and fuel consumption values. Even the most demanding emission limits can be achieved when adding exhaust gas aftertreatment systems like diesel particulate filters and DeNOx catalytic converters. “Homogeneous diesel combustion” has an enormous emission reduction potential limiting the effort on exhaust gas aftertreatment in future Summary
