Sec. 88.102-94  Definitions.

    Any terms defined in 40 CFR part 86 and not defined in this part 
shall have the meaning given them in 40 CFR part 86, subpart A.
    Adjusted Loaded Vehicle Weight is defined as the numerical average 
of the vehicle curb weight and the GVWR.
    Dual Fuel Vehicle (or Engine) means any motor vehicle (or motor 
vehicle engine) engineered and designed to be operated on two different 
fuels, but not on a mixture of the fuels.
    Flexible Fuel Vehicle (or Engine) means any motor vehicle (or motor 
vehicle engine) engineered and designed to be operated on any mixture of 
two or more different fuels.
    Heavy Light-Duty Truck means any light-duty truck rated greater than 
6000 lbs. GVWR.
    Light Light-Duty Truck means any light-duty truck rated through 6000 
lbs GVWR.
    Loaded Vehicle Weight is defined as the curb weight plus 300 lbs.
    Low-Emission Vehicle means any light-duty vehicle or light-duty 
truck conforming to the applicable Low-Emission Vehicle standard, or any 
heavy-duty vehicle with an engine conforming to the applicable Low-
Emission Vehicle standard.
    Non-methane Hydrocarbon Equivalent means the sum of the carbon mass 
emissions of non-oxygenated non-methane hydrocarbons plus the carbon 
mass emissions of alcohols, aldehydes, or other organic compounds which 
are separately measured in accordance with the applicable test 
procedures of 40 CFR part 86, expressed as gasoline-fueled vehicle non-
methane hydrocarbons. In the case of exhaust emissions, the hydrogen-to-
carbon ratio of the equivalent hydrocarbon is 1.85:1. In the case of 
diurnal and hot soak emissions, the hydrogen-to-carbon ratios of the 
equivalent hydrocarbons are 2.33:1 and 2.2:1 respectively.
    Non-methane Organic Gas is defined as in section 241(3) Clean Air 
Act as amended (42 U.S.C. 7581(3)).
    Test Weight is defined as the average of the curb weight and the 
GVWR.
    Transitional Low-Emission Vehicle means any light-duty vehicle or 
light-duty truck conforming to the applicable Transitional Low-Emission 
Vehicle standard.
    Ultra Low-Emission Vehicle means any light-duty vehicle or light-
duty truck conforming to the applicable Ultra Low-Emission Vehicle 
standard, or any heavy-duty vehicle with an engine conforming to the 
applicable Ultra Low-Emission Vehicle standard.
    Zero-Emission Vehicle means any light-duty vehicle or light-
dutytruck conforming to the applicable Zero-Emission Vehicle standard, 
or any heavy-duty vehicle conforming to the applicable Zero-Emission 
Vehicle standard.
