LPG-fuelled tractor emit less 99% NOx than diesel equivalent during study at US port terminal
New data released from the U.S. Propane Education & Research Council (PERC) and New Jersey-based Port Newark Container Terminal (PNCT) shows that LPG-powered terminal tractors are significantly cleaner than their diesel counterparts in several key emissions reduction areas.
According to the testing, researchers collected emissions data from a MAFI-manufactured LPG terminal tractor and Tier 4 diesel technologies. The results confirm the first unit yielded 99% fewer NOx composite and idle emissions than either diesel tractor. Additionally, the LPG tractor produced 77.5% fewer THC idle emissions, 14% fewer brake-specific CO2 emissions, and 75% fewer TPM emissions than the diesel vehicles.
MAFI’s Autogas tractor is powered by Power Solutions International’s (PSI) 8.8-litre LPG engine, which is over 90% cleaner than mandated U.S. Environmental Protection Agency (EPA) standards and certified to the optional ultra-low NOx emissions standard as defined by the California Air Resources Board (CARB) for heavy-duty engines with .02 grams of per brake horsepower. Plus, the propane engine competes with diesel engines on performance, providing 270 horsepower with 565 lb-ft of torque.
“This near-zero emissions technology tractor is available now for an affordable price,” said Gavin Hale, vice president of business development at the Propane Education & Research Council (PERC). “LPG technology adoptions are continuing to grow throughout the country to eliminate diesel emissions and make significant strides toward greenhouse gas reduction.”
Not only are LPG-powered terminal tractors cost effective, there is also grant money available through the Diesel Emissions Reduction Act (DERA) to support the transition to clean Autogas fleet technology, according to Hale.
