Measurement of Fuel Evaporative Emissions From Gasoline Powered Passenger Cars and Light Trucks Using the Enclosure Technique

1991-04-01
HISTORICAL
J171_199104
This SAE Recommended Practice describes a procedure for measuring evaporative emissions from fuel systems of passenger cars and light trucks. Emissions are measured during a sequence of laboratory tests that simulate typical vehicle usage in a metropolitan area during summer months: 1.) A 1 h soak representing one diurnal cycle in which temperature of fuel in the vehicle's tank is raised from 15.6 to 28.9 degrees C (60 to 84 degrees F). 2.) A 17.9 km (11.1 mile) run on a chassis dynamometer. 3.) A 1 h hot soak immediately following the 17.9 km (11.1 mile) drive. The method described in this document, commonly known as the SHED (Sealed Housing for Evaporative Determination) technique, employs an enclosure in which the vehicle is placed during the diurnal and hot soak phases of the test.

HISTORICAL
J923_199104
This SAE Recommended Practice outlines basic nomenclature in common use for truck and bus drive axle designs. Over a period of years there have been many different designs introduced; however, for this report, only the most common have been selected and only their general construction is illustrated to show the nomenclature of the various parts.
