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.
