Title: Evaluation of exhaust emissions from a Bi-fueled vehicle operating on liquid and gaseous fuels. Topical report, June-July 1995

Abstract

Exhaust emissions were characterized from a bi-fueled vehicle operating on compressed natural gas and two gasolines over a heavy acceleration/high speed driving cycle and during cold temperature operation. The test fuels included compressed natural gas (CNG) meeting California Air Resources Board emissions certification specifications, industry average gasoline formulated to the specifications of Reference Fuel A (RF-A) used in the CRC/Auto Oil program, and Federal reformulated gasoline (RFG) purchased at a commercial service station in metropolitan Houston. Exhaust emissions were evaluated over the light-duty chassis dynamometer portion of the Federal Test Procedure at 75 deg F and at 20 deg F, and the REP05 - a hot, stabilized, high speed, high acceleration driving cycle developed by the EPA to be representative of non-FTP, in-use driving. In addition, CNG emissions were evaluated over the US06 driving cycle. Average regulated exhaust emissions (total hydrocarbons, methane, carbon monoxide, and oxides of nitrogen) were evaluated in a manner consistent with the Code of Federal Regulations.
