INSTRUMENTATION AND TECHNIQUES FOR VEHICLE REFUELING EMISSIONS MEASUREMENT

1993-05-01
HISTORICAL
J1045_199305
This SAE Recommended Practice describes a procedure for measuring the hydrocarbon emissions occurring during the refueling of passenger cars and light trucks. It can be used as a method for investigating the effects of temperatures, fuel characteristics, etc., on refueling emissions in the laboratory. It also can be used to determine the effectiveness of evaporative emissions control systems to control refueling emissions. For this latter use, standard temperatures, fuel volatility, and fuel quantities are specified.

This SAE Recommended Practice describes a procedure for measuring the hydrocarbon emissions occurring during the refueling of passenger cars and light trucks. It can be used as a method for investigating the effects of temperatures, fuel characteristics, etc., on refueling emissions in the laboratory. It also can be used for determining the reduction in emissions achieved with emission control hardware. For this latter use, standard temperatures, fuel volatility, and fuel quantities are specified.

This SAE Standard presents the basic size and tolerance information for the design and manufacture of thrust washers. In most cases, the standard employs nominal figures in both metric and inch-pound units and, therefore, does not necessarily provide exact equivalents.

MEASUREMENT OF FUEL EVAPORATIVE EMISSIONS FROM GASOLINE POWERED PASSENGER CARS AND LIGHT TRUCKS USING THE ENCLOSURE TECHNIQUE

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: a 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 °C (60 to 84 °F) b A 17.9 km (11.1 mile) drive on a chassis dynamometer c 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.

MEASUREMENT OF FUEL EVAPORATIVE EMISSIONS FROM GASOLINE POWERED PASSENGER CARS AND LIGHT TRUCKS USING THE ENCLOSURE TECHNIQUE

J171_197009
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 hr soak representing one diurnal cycle in which temperature of fuel in the vehicle’s tank is raised from 60 to 84 F. 2 A 7 mile run on a chassis dynamometer. 3 A 1 hr hot soak immediately following the 7 mile run. The method described in this recommended practice for measuring the weight of fuel vapors emitted during the tests differs from that described in SAE J170. SAE J170 employs activated carbon traps connected to the fuel system at locations where vapors are expected to escape. Vapors from these openings are absorbed by the traps, and the gain in weight of the traps represents the fuel evaporative emissions.

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 60-84°F (15.6-28.9°C). 2 An 11.1 mile (17.9 km) run on a chassis dynamometer. 3 A 1 h hot soak immediately following the 11.1 mile (17.9 km) run. The method described in this recommended practice for measuring the weight of fuel vapors emitted during the tests differs from that described in SAE J170a (July, 1972). SAE J170a employs activated carbon traps connected to the fuel system at locations where vapors are expected to escape. Vapors from these openings are absorbed by the traps, and the gain in weight of the traps represents the fuel evaporative emissions.

Spark Arrester Test Procedure for Large Size Engines

J342_201303
This SAE Recommended Practice establishes equipment and procedures for the evaluation of the effectiveness and other performance characteristics of spark arresters or turbochargers used on the exhaust system of large engines normally used in a railroad locomotive, stationary power plant, and other similar applications. This document does not cover applications requiring flame arresting, exhaust gas cooling, or isolation from explosive gases. Two test methods are presented: a laboratory test using ambient air (cold test) and an engine test using exhaust gases (hot test). The hot test is preferred. Arresters tested by the provisions of this document can be expected to perform as tested when tilted no more than 45 degrees from their normal position. Test results from a spark arrester or turbocharger evaluated by the hot test can be applied to different engines of similar design, provided the data shows it to be effective in the applicable flow ranges.
