The The project's goal is to demonstrate reduced emissions and improved fuel economy and to evaluate the feasibility of converting NYCT's fleet of 2,800 RTS buses to hybrid drive at the normal mid-life powertrain overhaul. NYCT set aggressive emissions targets for the bus of 0.06 gpm of PM, 15.0 gpm of NOx, and a fuel economy objective of 4.3 mpg. The series hybrid-electric drive system is designed and integrated by Allison Transmission, a division of General Motors. It features a single high-powered AC induction motor and gear reduction coupled with a genset to maintain voltage in the traction batteries. The bus is fitted with a CRT continuously regenerating particulate trap produced by Johnson Mathey Inc. (JMI). The JMI trap technology is sensitive to fuel sulfur levels, and therefore requires the use of reduced sulfur diesel fuel(less than 50 ppm sulfur). The bus began a six-month revenue service test in 1999 and was emission tested in April 1999. The project sponsors included DARPA, Electricore, and the New York Power Authority; the project cost was $1.25 million. ---http://onlinepubs.trb.org/onlinepubs/tcrp/tcrp_rpt_59.pdf ---http://www.walshcarlines.com/pdf/Navc9837.pdf |
