    U.S. EPA / Heavy-Duty Engine and Vehicle Standards and Highway Diesel Fuel Sulfur Control Requirements. In December , EPA adopted a rulemaking to establish stringent standards designed to reduce emissions from on-road heavy-duty trucks and buses by up to 95 percent and to cut the allowable levels of sulfur in diesel fuel by 97 percent.

CONTROL OF EXHAUST EMISSIONS FROM INTERNAL COMBUSTION ENGINED VEHICLES. attributed to heavy-duty diesel vehicl es and aircraft. Heavy-Duty Highway Compression-Ignition and Spark-Ignition Engines: Evaporative Emission Standards (PDF) (1 pg, 84 K, MarchEPAB) Phase 1 Greenhouse Gas Emissions Standards and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles.

The U.S. Environmental Protection Agency (EPA) is establishing a comprehensive national control program that will regulate the heavyduty vehicle and its fuel as a single system.

As part of this program, new emission standards will begin to take effect in model year and will apply to heavy-duty highway engines and vehicles. Heavy heavy-duty diesel engines (including urban bus): HHDDE > 33,; Testing. Current federal regulations do not require that complete heavy-duty diesel vehicles be chassis certified, instead requiring certification of their engines (as an option, complete heavy-duty diesel vehicles un lbs can be chassis certified).

SCR Workshop for On Road Medium Duty and Heavy Duty Engines: The California Air Resources Board (ARB) staff invites you to participate in a public workshop regarding medium-heavy and heavy-heavy diesel engine certification requirements related to engines using SCR control technology for and later model year on-road heavy-duty diesel engines and off-road compression ignition engines.

Two- and three-wheel vehicles (motorcycles) [][] Carbon dioxide emissions of from passenger cars and light commercial vehicles (once controlled through voluntary agreements with the automotive industry) have been regulated since CO 2 emissions from selected categories of heavy-duty vehicles (HDV) are regulated from Canada: Heavy-Duty Engines & Vehicles.

Heavy-Duty Engines; Heavy-Duty Vehicles; Heavy-Duty Engines. Diesel Engines. The On-Road Vehicle and Engine Emission Regulations (SOR/) [] introduced two sets of emisison standards for heavy-duty diesel truck and bus engines, that are harmonized with the US standards.

Phase 1 standards—equivalent to US standards—apply. National Emissions Invento ry forheavy ­duty diesel vehicles contributed 36 percent of the particulate matter, 30 percent o f the NOx and 26 percent of the SOx from the transportation sector, yet comprise only 2 percent of the total number of vehicles on the roadways.

D iesel. In the U.S., ultralow sulfur diesel fuel (ULSD, sulfur content less than 15 ppm) has been phased in since for on-road diesel vehicles, 2 and biodiesel blends have become widely available.

While most heavy-duty (HD) vehicles are diesel, currently only a small fraction of light-duty vehicles in the U.S. are diesel. 3,4Cited by: Factors Affecting Heavy-Duty Diesel Vehicle Emissions Article (PDF Available) in Journal of the Air & Waste Management Association () 52(1) February with Reads.

Three out of four trucks on the road are powered by diesel and 98 percent of the large over-the-road Class 8 trucks are diesel. Over the last 20 years, emissions from heavy-duty diesel trucks, buses and other vehicles have been reduced by 95 percent for nitrogen oxides (NOx) - an ozone precursor - and 90 percent for particulate emissions.

These requirements went into effect in late for on-road diesel vehicles, while off-road diesel fuel used in construction equipment and trains will take effect over the next five years. Lower sulfur diesel fuel allows the use of advanced emission control technologies, which when combined, can reduce emissions more than 85 percent.

Global Strategy to Introduce Low Sulphur Fuels and Clean Diesel Vehicles sets first global timeline for cleaner fuels: all countries adopt all countries to 50 ppm low sulfur fuels byand most countries go to ultra-low (10 ppm) sulfur in fuels by ; Strategy launched at COP 21 in Paris, the first global plan to reduce black carbon emissions from cars, trucks and buses by over 90%.

Nevada requires used car dealers to issue a valid emissions test, when required, on any vehicle they sell. In private transactions, the test is the buyer's responsibility. Light duty diesel vehicles undergo testing on a dynamometer.

The technician will also perform an opacity test. Heavy Duty Diesel Engine Standards All manufacturers of and model year heavy-duty diesel vehicles with a GVWR of 14, pounds or greater shall provide certification that the engine used in the manufacturer’s vehicle comply with the applicable exhaust emissions standards under Ti Section of the California Code.

Diesel exhaust is the gaseous exhaust produced by a diesel type of internal combustion engine, plus any contained composition may vary with the fuel type or rate of consumption, or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator or other.
