SPARK-IGNITION ENGINES--Table of Contents
 
          Subpart B_Emission Standards and Related Requirements
 
Sec.  1048.105  What evaporative emission standards and requirements apply?

    The requirements of this section apply to all engines that are 
subject to this part, except auxiliary marine engines.
    (a) Starting in the 2007 model year, engines that run on a volatile 
liquid fuel (such as gasoline), must meet the following evaporative 
emissions standards and requirements:
    (1) Evaporative hydrocarbon emissions may not exceed 0.2 grams per 
gallon of fuel tank capacity when measured with the test procedures for 
evaporative emissions in subpart F of this part.
    (2) For nonmetallic fuel lines, you must specify and use products 
that meet the Category 1 specifications in SAE J2260 (incorporated by 
reference in Sec.  1048.810).
    (3) Liquid fuel in the fuel tank may not reach boiling during 
continuous engine operation in the final installation at an ambient 
temperature of 30 [deg]C. Note that gasoline with a Reid vapor pressure 
of 62 kPa (9 psi) begins to boil at about 53 [deg]C.
    (b) Note that Sec.  1048.245 allows you to use design-based 
certification instead of generating new emission data.
    (c) If other companies install your engines in their equipment, give 
them any appropriate instructions, as described in Sec.  1048.130.
