A team from the National University of Singapore (NUS) reports on the effects of piston bowl geometry on the combustion and emission characteristics of a diesel engine fueled with biodiesel under medium load condition in a paper in the journal Fuel.

The team investigated three different bowl geometries in its numerical study: Hemispherical Combustion Chamber (HCC), Shallow depth Combustion Chamber (SCC), and the baseline Omega Combustion Chamber (OCC). All used the same compression ratio of 18.5.
