To study the application of biodiesel-methanol blends on diesel engines, combustion and emission experiments
are done on a single cylinder diesel engine. Results show that with the blend of methanol, the combustion delays; the peak
combustion pressure decreases at small load and increases at middle and large loads; peak heat release rate is similar; HC,
CO and smoke decrease; variation of NOX emission is not clear. The study proves that with the methanol blending, major
emission pollutants can be reduced and the combustion process can be improved at middle and large loads.
