California Jump Start
The following percentages indicate minimum fuel savings on aerodynamic technologies, according to third-party testing used by the U.S. Environmental Protection Agency’s SmartWay Transport Partnership. “Advanced” refers to later generation products that achieved 5 percent or better fuel savings without being used in combination with a gap fairing or tail device.
1% TRAILER GAP REDUCERS. Recommended to be used with side skirts. Products are the Carrier Transicold Gap Fairing, Freight Wing gap reducer, Laydon Composites gap reducer and Nose Cone’s 3-D gap reducer.
1% TRAILER BOAT TAIL. Recommended to be used with side skirts. Devices are the Aerodynamic Trailer Systems dual lobe boat tail, AeroVolution inflatable boat tail, ATS SmartTail and Transtex rear trailer fairing.
4% TRAILER SIDE SKIRTS. Recommended for use with a gap reducer or tail. Among the manufacturers are Carrier Transicold, Fleet Engineers, Freight Wing, Laydon Composites, Ridge Corp., Silver Eagle, Transtex and Utility Trailer.
5% ADVANCED TRAILER END FAIRINGS. Makers are ATDynamics, ATS and SmartTruck.
5% ADVANCED TRAILER SKIRTS. Makers are Aerofficient, Airflow Deflector, ATDynamics-Transtex, Atlantic Great Dane, Carrier Transicold, Freight Wing, Laydon Composites, Ridge Corp., Silver Eagle, Strehl, Sweet Bottom, Transtex, Utility Trailer, Wabash National and Windyne.
Reefer update schedule
Reefer owners who run in California face another set of deadlines, depending on the age of what the state calls transport refrigeration units.
California-based TRUs had to be registered with the state Air Resources Board by July 31, 2009, and the following month CARB staff began enforcement.
Beginning with 2001 model year reefer engines, CARB set deadlines for low-emission TRUs, followed by ultra-low-emission TRUs. Model year 2004 with 25 hp and greater must meet the standard by Dec. 31, and model year 2005’s deadline is Dec. 31, 2012.
For each year after that, add seven years to the TRU engine year to get the compliance year for that engine — for example, model year 2011 engine will be Dec. 31, 2018.
