There are millions of diesel powered vehicles and stationary engines around the world. Although diesel dual fuel systems
have already been developed for specific engines, there are very few universal diesel-CNG systems available to retrofit other engines. Besides being cheaper to operate and reducing dependence on foreign oil, diesel-CNG systems reduce the particulate emissions that have been found to be a health hazard (see CARB School Bus Study
). However, although diesel dual fuel systems (diesel-CNG and diesel-LPG) are proven technology, they do not appear to be recognized as alternative fuel systems by the US Department of Energy's AFDC
For those people having a fleet of diesel engines and readily available supply of natural gas, Technocarb
has recently developed the EcoDiesel System
, which is a universal, self-calibrating diesel-CNG system that can be installed on any turbocharged engine. Depending upon the amount of diesel fuel purchased annually, a diesel dual fuel system could be a viable option to reduce operating costs, emissions, and dependence on foreign oil.
