Emission characteristics of diesel engines fuelled with B20 with different DPF, DOC and EGR arrangements

In the present investigation, pre- and post-combustion techniques are adopted for diesel engines. This work focuses on optimisation of engine performance powered with biodiesel B20 blend by incorporating pre- and post-combustion techniques addressing emission from diesel engines within acceptable no...
