Explanation:

CReDI is a two-stage fuel distribution system which offers greater flexibility than a normal engine.

It is electronically controlled through an electronic engine management System.

It reduces particulate/soot and gaseous emissions (e.g. (NOx emission) because the efficacy of the catalytic converter (device that filter pollutants) is increased under this method. You will read about catalytic converters in higher classes NCERT
