Flywheels for Single-Plate Spring-Loaded Clutches

2012-05-31

CURRENT

J618_201205

This SAE Recommended Practice applies to flywheels for dry spring-loaded clutches used on internal combustion engines. Figure 1 and Tables 1, 2, and 3 report information currently used in the industry. Clutches requiring other dimensions are also manufactured. Dimensions given are primarily for single-plate clutches. Flywheels for two plate clutches have the same dimensions if an adaptor for the intermediate plate and second driven disc is supplied with the clutch. If instead the flywheel is to be extended to adapt the intermediate plate and second driven member, consult the clutch manufacturer for the required J dimension and drive arrangements for the intermediate plate. See SAE J1806 for flywheels for size 14 and 15.5 two plate pull-type clutches.

Impact of Alternative Fuels on Engine Test and Reporting Procedures

2011-09-06

CURRENT

J1515_201109

The guidelines in this SAE Information Report are directed at laboratory engine dynamometer test procedures with alternative fuels, and they are applicable to four-stroke and two-stroke cycle spark ignition (SI) and diesel (CI) engines (naturally aspirated or pressure charged, with or without charge air cooling). A brief overview of investigations with some alternative fuels can be found in SAE J1297. Other SAE documents covering vehicle, engine, or component testing may be affected by use of alternative fuels. Some of the documents that may be affected can be found in Appendix A. Guidelines are provided for the engine power test code (SAE J1349) in Appendix D. The principles of these guidelines may apply to other procedures and codes, but the effects have not been investigated. The report is organized into four technical sections, each dealing with an important aspect of testing or reporting of results when using alternative fuels.

Manual Transmission and Transaxle Efficiency and Parasitic Loss Measurement

2011-09-02

CURRENT

J2453_201109

Because of the intense focus on CAFE and fuel emission standards, optimization of the automobile drivetrain is imperative. In light of this, component efficiencies have become an important factor in the drivetrain decision-making process. It has therefore become necessary to develop a universal standard to judge transmission efficiency. This SAE Recommended Practice specifies the dynamometer test procedure which maps a manual transmission’s efficiency. The document is separated into two parts. The first compares input and output torque throughout a specified input speed range in order to determine “in-gear” transmission efficiency. The second procedure measures parasitic losses experienced while in neutral at nominal idling speeds and also churning losses while in gear. The application of this document is intended for passenger car and light truck. All references to transmissions throughout this document include transaxles.

Sleeve Type Half Bearings

2011-06-10

CURRENT

J506_201106

This SAE Standard defines the normal dimensions, dimensioning practice, tolerances, specialized measurement techniques, and glossary of terms for bearing inserts commonly used in reciprocating machinery. The standard sizes cover a range which permits a designer to employ, in proper proportion, the durability and lubrication requirements of each application, while utilizing the forming and machining practices common in manufacture of sleeve type half bearings. Not included are considerations of hydrodynamic lubrication analysis or mechanical stress factors of associated machine structural parts which determine the nominal sizes to be used, selection of bearing material as related to load carrying capacity, and economics of manufacture. For information concerning materials, see SAE J459 and SAE J460. These suggested sizes provide guidelines which may result in minimal costs of tooling but do not necessarily represent items which can be ordered from stock.

This SAE Information Report covers thin coatings of resinous based materials that can be placed on the metallic outer diameter of radial lip-type shaft seals to provide sealing when the mating bore finish is too rough to insure a proper seal (typically when finish exceeds 2.54 µm Ra, or in pressurized applications.) The coatings will have the following characteristics: a. Material shall dry to a tough, flexible, and non-tacky film. b. Thickness typically ranges from 0.005 to 0.076 mm. c. It shall not crack, flake, or powder when scraped. d. Coating shall adhere to seal case as noted in text. e. The sealer shall not show any evidence of peeling, blistering, softening, or dissolution when tested in media to be sealed.

Determination of Sulfur Compounds in Automotive Exhaust

2002-10-21

CURRENT

J1280_200210

This SAE Information Report deals exclusively with the determination of sulfur compounds in automotive exhaust. Engine operating cycles and interpretation of results are not covered. Methods described in detail are those that have been or are being used by various laboratories. None are specifically recommended as superior to others. Since intensive measurement of automotive sulfur compounds is a relatively new activity, methods and practices have changed rapidly. Some methods are more experimental than others and are so noted in the test.
