U.S. and California regulations do not require complete heavy-duty diesel vehicles to be chassis certified, but rather require certification of their engines (optionally, complete heavy-duty diesel vehicles under 14,000 lbs can be chassis certified). Therefore, the basic standards are expressed in g/bh·hr and require emissions testing on the transient cycle of the FTP engine dynamometer (however, chassis certification may be required for heavy gasoline vehicles complete with the relevant emission standards, expressed in g/mile). This year, business owners in San Jose, Santa Cruz, Gilroy, Sunnyvale, Fremont and Mountain View that operate diesel-powered trucks may find that their old trucks are allowed to drive illegally on California roads. If you own a commercial vehicle with a total laden weight of 14,001 to 26,000 pounds and it does not meet the new emission standards, you will not be able to renew your registration. Commercial diesel trucks will be phased out by the model year. The older your vehicle, the sooner you need to purchase a new commercial vehicle, from: Class II diesel FIPs must have a fleet of 10 heavy diesel vehicles or more than 18,000 lbs of GVWR or more and are only allowed to inspect other owners or lessees of fleets of 10 or more. The emission standards included new and very strict limits for particulate matter (0.01 g/bhp·h) and NOx (0.20 g/bhp·h). The particulate emission standard entered into full force in 2007. The NOx standard was gradually introduced for diesel engines between 2007 and 2010. Phased implementation was defined based on a percentage of revenues: 50% from 2007 to 2009 and 100% in 2010 (gasoline engines are subject to these standards based on an introduction that requires 50% compliance in 2008 and 100% compliance in 2009). In practice, very few engines that reached the NOx limit of 0.20 g/bhs appeared before 2010.
During the period 2007-2009, most manufacturers decided to comply with a NOx emission limit value (FEL) of around 1.2 g/hp for most of their engines. Due to this compliance trajectory during the NOx limitation phase, the engines produced in 2007-2009 were technologically very different from those that had to be met in 2010 and later, when all engines had to meet the NOx limit of 0.2 g/bh·h. While it is common to refer to the “2010 standards” in a way that implies that they are different from the “2007 standards,” there was no legal standard for 2010 that differed from 2007. Starting in 1998, additional emission testing requirements were added in several stages. These include: Starting in 2007, manufacturers could choose to certify complete heavy-duty diesel (HDV) vehicles with a total laden weight of 14,000 lbs or less as an option for engine certification. The emission limit values for heavy-duty vehicles in the petrol cycle with the same GVWR shall apply. Diesel engines that were eventually certified as complete vehicles were not allowed to be included in an average, banking or trading program for criteria emissions. However, they were included in the phased implementation calculations, where 50% of engines had to comply with the final NOx limit of 2010. Thus, certified diesel engines were considered legally equivalent to a 0.20 g/bh NOx engine as long as they met the limits of the 2008 Otto Cycle HDV (0.2 g/mile NOx and 0.02 g/mile particulate matter for 8500 lbs < GVWR ≤ 10000 lb and 0.4 g/mile NOx and 0.02 g/mile pm per 10000 lb < GVWR ≤ 14000 lb). After 2011, all manufacturers of heavy-duty vehicles complete with GVWR ≤ 14000 lbs (mainly heavy-duty trucks and commercial vehicles) introduced this optional approach to chassis certification due to the GHG regulations for heavy-duty vehicles applicable for MY 2014. Effective March 2, 2020, the New Jersey Motor Vehicle Commission (NJMVC) will launch a pilot program for road inspections of medium-weight diesel vehicles (VDSVs) under N.J.A.C. 13:26-14 and N.J.A.C.
13:20-46.3. The pilot project is being conducted in collaboration with the New Jersey Department of Environmental Protection (NJDEP) and with the assistance of the New Jersey State Police (NJSP). From 1. As of January 2020, private commercial waste truck companies licensed or registered with the New York City Business Integrity Commission (BIC) must meet the requirements of Local Law 145 of 2013. Mandatory low NOx emission standards apply to diesel cycle and heavy-duty gasoline engines (GVWR > 14,000 lbs), as well as engines used in medium-weight vehicles with a GVWR of 10,001 to 14,000 lbs.
