The US Environmental Protection Agency (EPA) is proposing to make it easier for manufacturers to gain approval to sell fuel conversion systems. The proposed rule would cover conversions of light-duty vehicles and heavy-duty highway vehicles and engines, and would apply to all clean alternative fuels. Exhaust, Evap, and OBD testing 2.

A dynamic driving style demands an equally dynamic recirculation of exhaust gases. With a combination of high- and low-pressure exhaust-gas recirculation, the air-flow management system becomes even more flexible. To ensure optimum NO x conversion, the exhaust gases must be hotter than 200 degrees Celsius.
