    Experimental study of exhaust emissions and performance of a dual fuel IDI diesel engine by Badr, O.

    Published 1999
    “…Dual fuel engines of the compression ignition type provide an alternative approach for I.C. engines to improve economy, reduce exhaust emissions and achieve a greater power. The present contribution is an experimental investigation to evaluate such a statement using a modified Ricardo E6 indirect injection diesel engine. …”
