Combustion and emission characteristics of Multiple Premixed Compression Ignition (MPCI) mode fuelled with different low octane gasolines

The diesel fuel has lower CO and HC emissions than the gasoline-type fuels do, but much higher pressure rise rate, NOx and soot emissions due to high combustion temperature and poor premixing. Therefore, the low octane gasoline fuels are more suitable than the diesel for compression ignition engines in terms of the emissions.
