City of Los Angeles Experience With a Methanol-Fueled Dump Truck 921536

THE CITY OF LOS ANGELES operated a methanol-fueled dump truck for a period of 23 months. The vehicle was in asphalt paving service and was equipped with a Cummins L10 engine fueled with 95 percent methanol and 5 percent Avocet ignition improver. The City operated a control vehicle, equipped with a diesel-fueled Cummins L10, at the same location in similar service. The methanol-fueled truck was initially not equipped with a catalytic converter but one was added during the course of the demonstration. The methanol-fueled truck fueled at a City of Los Angeles fueling facility dedicated to this vehicle. During the demonstration period, fuel consumption, uptime, vehicle performance and steady state emissions were measured.
