Aerosol additive means a chemical mixture in aerosol form generally used as a motor vehicle engine starting aid or carburetor cleaner and not recommended to be placed in the fuel tank. Aftermarket fuel additive means a product which is added by the end-user directly to fuel in a motor vehicle or engine to modify the performance or other characteristics of the fuel, the engine, or its emissions. Base fuel means a generic fuel formulated from a set of specifications to be analytical engine definition of a particular fuel family.

Basic emissions means the total hydrocarbons, carbon monoxide, oxides of nitrogen, and particulates occurring in motor vehicle or engine emissions. Bulk fuel additive means a product which is added to fuel at the refinery as part of the analytical engine definition blending stream or after the fuel is transported from the refinery but before the fuel is purchased for introduction into the fuel tank of a motor vehicle. Emission characterization means the determination of the chemical composition of emissions. Emission sampling means the removal of a fraction of collected emissions for testing purposes. Emission speciation means the analysis of vehicle or engine emissions to determine the individual chemical compounds analytical engine definition comprise those emissions.
Engine Dynamometer Learn more here EDS means the transient engine speed versus torque time sequence commonly used in heavy-duty engine evaluation. Evaporative Emission Generator EEG means a fuel tank or vessel to which heat is applied to cause a portion of the fuel to evaporate at a desired rate.

Evaporative fuel additive means a fuel additive which, when mixed with its specified base fuel, causes an increase in the RVP of the base fuel by 0. Excluded from this definition are fuel analytical engine definition used with fuels which are supplied to motor vehicle engines by way of sealed containment and delivery systems. Federal Test Procedure FTP enginr the body of exhaust and evaporative emissions test procedures described in 40 CFR 86 for the certification of new motor vehicles to Federal motor vehicle emissions standards.
Fuel family means a set of fuels and fuel additives which share basic chemical and physical formulation characteristics and can be used in the same engine or vehicle. Nitrated polycyclic aromatic hydrocarbons NPAH means the class of compounds whose molecular structure includes two or more aromatic rings and contains one or more nitrogen substitutions. Non-catalyzed emissions means exhaust emissions not subject to an effective aftertreatment analytical engine definition such as a functional catalyst or particulate trap. Oxygenate compound means an oxygen-containing, ashless organic compound, such as an alcohol or ether, which may be used as a fuel or fuel additive. Polycyclic aromatic hydrocarbons PAH means the class of hydrocarbon compounds whose molecular structure includes two or more aromatic rings.

Semi-volatile organic compounds means that fraction of gaseous combustion ddefinition which consists of compounds with greater than twelve carbon atoms and can be trapped in sorbent polymer resins. Vehicle type means the divisions of motor vehicles according to combustion cycle and intended fuel class, including, but not analytical engine definition limited to, Otto cycle gasoline-fueled vehicles, Otto cycle methanol-fueled vehicles, diesel cycle diesel-fueled vehicles, and diesel cycle methanol-fueled vehicles. Whole emissions means all components of unfiltered combustion emissions or evaporative emissions.
If manufacturers elect to comply by participation in a group, each manufacturer continues to be individually subject to the requirements of subpart F of this read article, and responsible for testing under this subpart.
Nothing in this subsection b shall be definitikn to require a manufacturer to rely on another manufacturer's testing. If the Administrator determines that the product is registrable under this section, then the Administrator shall promptly register the product, provided that the applicant has analytical engine definition all of the other requirements for registration under subpart B or subpart C of this part, and contingent upon satisfactory submission of required information under paragraph c 2 iii of this section.]
Speak to the point
In my opinion you commit an error. Let's discuss. Write to me in PM, we will communicate.
I can not take part now in discussion - it is very occupied. I will be free - I will necessarily express the opinion.
The matchless message, very much is pleasant to me :)
