The effects of methanol–diesel direct dual fuel injection at varying injection pressures in a compression ignition engine

Direct injection of methanol and diesel benefits over other fuel-air mixture preparation strategies.

This work investigates the effect of methanol and diesel injection pressure (IP) on combustion and emissions characteristics. CONVERGE CFD (computational fluid dynamics) was used for simulations, and the combustion model was validated with the experimental data.

The analysis found that 270 bar diesel IP and 230 bar methanol IP showed better engine performance.

Methanol can be an alternative fuel for internal combustion engines.
