Emission characteristic of small diesel engine fuelled by preheat biodiesel

The viscosity of fuels has important effects on fuel droplet formation, atomization, vaporization and fuel–air mixing process, thus influencing the exhaust emissions and performance parameters of the engine. The higher viscosity has effect on combustion and proper mixing of fuel with air in the comb...
