(Whittier, CA) -- The Sanitation Districts of Los Angeles County have recently begun to use five liquified natural gas (LNG) trucks to transfer municipal solid waste from Sanitation Districts' transfer stations to landfills for disposal. The LNG trucks are the latest addition to the Sanitation Districts' comprehensive clean fuels program, the goal of which is to replace Sanitation Districts' wastewater and solid waste operational vehicles with compressed natural gas and LNG vehicles.
Cummins ISX 15-liter engines, equipped with Westport's High Pressure Direct Injection (HPDI) fueling system, power the LNG trucks. The HPDI system, certified by the California Air Resources Board and the United States Environmental Protection Agency, allows engines to operate at lower emissions using LNG instead of diesel, as the primary fuel, using only a small quantity of diesel as the starting ignition source.
