Sep 03, 2020 · Photo:Getty Images. In 2005, Government Fleet and other trade publications ran articles about the coming mandate for a new diesel fuel, Ultra Low Sulphur, and the coming changes in both 2007 and 2010 diesel engines. Little did we in government fleet, or the industry as a whole, realize then how greatly those changes would impact vehicle costs in both capital and maintenance.
CALIFORNIA EVAPORATIVE EMISSIONS STANDARDS of the useful life and emissions at the low-hour test point. In these cases, adjust the official emission results for each tested vehicle or engine at the selected test point by adding the factor to the measured emissions. If the factor is less than zero, use zero. Additive

Emission Standards:USA:Heavy-Duty Onroad Engines
Summary of Emission LimitsModel Year 1974-2003Model Year 2004-2006Model Year 2007 and LaterThe first federal emission limits were introduced in 1974 and gradually tightened in a number of steps, as shown in Table 1. The current mandatory emission standards for heavy-duty engines were phased-in over the period of 2007-2010. The table also covers the 2015 California Optional Low NOx Standards. In addition to the limits shown above, the following emission standards apply:1. Smoke OpacitySmoke opacity limits of 20% / 15% / 50% at acceleration/lug/peak modes, respectively, have been applicable siNEA Air Pollution RegulationsUnder the Environmental Protection and Management (Vehicular Emissions) Regulations, it is an offence for the driver of a motor vehicle to leave the engine of a vehicle idling while it is stationary, for reasons other than traffic conditions. The rationale is to minimise pollution. It will in turn reduce fuel wastage.
Federal Register ::Vehicle Test Procedure Adjustments for May 13, 2020 · In the Tier 3 Final Rulemaking, EPA required vehicle manufacturers to perform greenhouse gas (GHG) and CAFE fuel economy testing on the new Tier 3 test fuel, beginning for model year 2020 and later vehicles. Changes to the fuel used for emissions testing can result in a change in emission results on the tests.
Diesel Engine Idling Requirements - 2008 and Subsequent; Idle Options Description:Engine Shutdown System All-new heavy-duty diesel engines shall be equipped with an engine shutdown system that automatically shuts down the engine after 300 seconds of continuous idling operation once the vehicle is stopped, the transmission is set to neutral or park, and the parking brake is engaged.
Regulations for Emissions from Vehicles and Engines - US EPAThe Direct Final Rule included amendments as follows:Corrections to the Tier 3 motor vehicle emission and fuel standards and the Quality Assurance Program; Revisions to the test procedures and compliance provisions for nonroad spark-ignition engines at or below 19 kW; Changes to address ambiguity regarding permissible design approaches for portable fuel containers meeting evaporative emission standards; Revisions to align with current requirements

LEV III extended PZEV-type, near-zero evaporative emission requirements to all light-duty vehicles by 2022. Manufacturers have two compliance options that include a zero evap-based fuel system test and a 2-day and 3-day + hot soak whole vehicle test in a Sealed Housing for Evaporative Determination (SHED) apparatus.
Understanding Engine Cert - California Air Resources Boardregulations, engine manufacturers must follow strict testing procedures to demonstrate or certify that their engine or vehicle meets the engine emission standards while operating in a specific service class (test cycle and weight restriction). An engine can not be placed in a vehicle and operated outside its service class designation.
