This SAE Information Report describes various dynamometer driving schedules currently in use in the world for measurement of exhaust emissions and fuel economy of passenger cars and light trucks. Issuance of this document will allow driving schedules to be deleted from individual test procedures, thus reducing the amount of repeated information in the SAE Handbook. This document includes: a. Descriptions of driving schedules; and b. Second-by second definition of speed versus time sequences.

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.

This practice applies to flywheels and flywheel-starter ring gear assemblies used with internal combustion engines of the spark ignition and diesel type equipped with a governor or speed limiting device. Engine sizes are those capable of using SAE No. 6 through SAE No. 00 flywheel housings. This practice applies to methods used to determine the rotational speed capability of flywheels for stresses imposed by centrifugal forces only.

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 to 84 F (15.6 to 28.9 C). 2 A 7.5 mile (12.1 km) run on a chassis dynamometer. 3 A 1 h hot soak immediately following the 7.5 mile (12.1 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. 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.

This SAE Recommended Practice is intended as a guide to the use of radial lip type seals. It has been prepared from existing literature, which includes standards, specifications, and catalog data of both oil seal producers and users and includes generally accepted information and data. The main reason for the preparation of the document is to make standard information available in one document to the users of oil seals.

This SAE standard outlines physical dimensions and nomenclature for the sizes of seals commonly used in engine coolant pumps of automotive type engines. Its purpose is to define a standard envelope to accommodate installation of various seal designs and to promote uniformity in seal nomenclature.

The methods presented in this document apply to the controlled testing of low temperature charge, air cooled, heavy duty diesel engines. This document encompasses the following main sections: a Definitions of pertinent parameters. b Vehicle testing to determine typical values for these parameters. c Description of the setup and operation of the test cell system. d Validation testing of the test cell system. While not covered in this document, computer modeling of the vehicle engine cooler system is recognized as a valid tool to determine cooler system performance and could be utilized to supplement the testing described. However, adequate in-vehicle testing should be performed to validate the model before it is used for the purposes outlined. The procedure makes references to test cycles that are prescribed by the United States Environmental Protection Agency (US EPA) and are contained in the Code of Federal Regulations.
