| Abstract |
Exhaust emissions from the two methanol-powered buses used in the California Methanol Bus Demonstration have been characterized. The M.A.N. SU 240 bus is powered by M.A.N.'s D2566 FMUH methanol engine, and utilizes catalytic exhaust aftertreatment. The GMC RTS II 04 bus is powered by a first-generation DDAD 6V-92TA methanol engine without exhaust aftertreatment. Emissions of HC, CO, NOxide, unburned methanol, aldehydes, total particulates, and soluble fraction of particulate were determined for both buses over steady-state and transient chassis dynamometer test cycles. Emission levels from the M.A.N. bus were considerably lower than those from the GMC bus, with the exception of NOxide. Comparison of emission levels from methanol-and diesel-powered buses indicates that substantial reduction in emissions (especially particulate and NOxide) are possible with careful implementation of methanol fueling. |
