Abstract
A diesel emission control system comprising two (2) catalyzed, monolithic ceramic exhaust filters, a diesel burner and electronic controller has been designed and installed on a 1982 GMC RTS-04 bus powered by a Detroit Diesel 6V-92TA engine.
The system reduces exhaust particulates by over 80 percent and is also effective in reducing carbon monoxide and hydrocarbon emission. A minor NOx reduction was also observed.
The New York City Transit Authority has operated the bus in downtown Manhattan since April, 1989. Its performance has been closely monitored and compared to a fleet of control buses running on the same route.
Exhaust emission levels have been measured at regular intervals by NYCDEP to determine the emission reduction efficiencies and to track deterioration factors. Operating experience with this system is reported.
