A novel fumigation technology for the use of methanol/ethanol as a dual fuel for compression ignition (diesel) engines has been developed to offer the option to replace the use of diesel with up to 40% of these renewable fuels, and to reduce the greenhouse emissions and fine particulate emissions from compression ignition engines, whether in transport or for stationary energy generation. This technology involves the addition of an apparatus to the air intake of a standard compression ignition engine, requiring no modification to the engine. This research found that the vortex creator design greatly shortens the required mixing length from 10 D to 1 D. In addition, we found in conservative estimation that the required ethanol evaporation distance (without heating) is more than 1 meter. Furthermore, a new dual fuel system design putting a vortex creator after the turbocharger was proposed.
