As of 2010, "clean fuel vehicle" covers trucks manufactured from 1999 to the present---see "U.S. Code Part 86" in References for the law that applies to you. A consumer need not worry about these restrictions if the catalytic converter was originally warrantied and it is compatible with his vehicle.
According to state, all vehicles and their emissions fall into categories.
For the aim of enactment, emission restrictions are are fitted to vehicle classifications. In 2005, the EPA amended emissions rules in both automobile and Motor lorry weight classes according to Gross Vehicle Weight Classifying (GVWR). For instance, EPA standards incorporate three popular vehicle classes: light-duty vehicles and light-duty trucks weigh up to 8,500 lbs. Heavy-duty vehicles weigh between 8,501 lbs. and 26,000 lbs. Vehicles are too defined according to emissions categories: transitionally low emissions vehicle (TLEV), low-emission vehicle (LEV), ultra low-emission vehicle (ULEV), or a nadir emission vehicle (ZEV). Due to the prevalence and contrasting styles of vehicles throughout the USA, the EPA used weight to start the method of defining standards for all vehicles traversing America's roads.
Certifications for Compatibility
Evaluation the manufacturer's statute on ancient converters before installing them.
All cutting edge EPA-approved catalytic converters must be so labelled and warranted for five second childhood or 50,000 miles (proof elsewhere "What You Should Notice..." in Resources for codes). Consumers may deploy "aftermarket" (or used) converters, but these must have the same warranty. This is the EPA's way of ensuring the converter's integrity regardless of the vehicle attached to it. That said, consumers must be aware that not all converters are necessarily compatible with all vehicles models. Four factors determine which kind of catalytic converter meets EPA standards: your vehicle's year, make and model, extremely as its engine type.
Restrictions by Class
U.S. Code 40, Part 86 divides emission standards by model year for different classes of vehicles: motorcycles, cars and light-to-heavy duty trucks---emission regulations reach back to 1978. Moreover, vehicles require different types of catalytic converters---there are two kinds: dual-bed and three-way---based on their year of production. When the government tightened emission standards, manufacturers equipped 1980-81 models with the "three-way" catalytic converter. Absolutely, EPA standards for light-duty trucks are divided into three categories based on model years. "Tier 0" applies to trucks produced between 1981and 1993. "Tier 1" applies to production years 1994-1999.The U.S. polity wants catalytic converters to block pollutants before they distance the extremity of your tailpipe.In 1971, the U.S. governance legalized catalytic converters in aligning to decrease four kinds of vehicles emissions: hydrocarbon, nitrogen oxides (NOx), carbon monoxide (CO) and carbon dioxide (CO2). In 1990, America's Disinfected Air Point too empowered the Duty of Transportation and Air Quality---a department of the Environmental Safeguard Agency---to enforce U.S. federal standards. Catalytic converters that discharge not applicable EPA standards are against the regulation, extension.
