Diesel Engine Smoke Measurement

2002-10-21

CURRENT

J255_200210

Measurement of diesel smoke in an accurate and consistent manner has been a serious problem for engine and vehicle manufacturers, users, and agencies charged with enforcing smoke limits. Several instruments, based on different principles and using different scales, are commonly used. In addition to these, human observation and judgement are often used to relate smoke to a variety of standards. The purpose of this SAE Information Report is to provide an understanding of the nature of diesel smoke, how it can be measured, and how the various measurement methods can be correlated. Except for defining the various types of smoke, the report deals solely with the steady-state measurement of visible, black smoke emitted from diesel engines.

Diesel Smoke Measurement Procedure

1995-03-01

HISTORICAL

J35_199503

This SAE Recommended Practice applies to the dynamometer test procedure which can be used to assess the smoke emission characteristics of vehicular diesel engines. In particular, this procedure describes the smoke test cycle, equipment and instrumentation, instrument checks, chart reading, and calculation for evaluation of an engine's transient smoke emission characteristic. In addition, this procedure offers guidelines to be used in establishing correlation between full flow in-line and end-of-line opacimeters. Since the type of test described here is transient in nature, a fast responding full flow opacimeter is required for the smoke measurements. Slow responding or sampling, or both, type instruments must not be used since they typically have excessive and variable response delays and do not provide an accurate measurement of an engine's transient smoke characteristics.

ENGINE TESTING WITH LOW TEMPERATURE CHARGE AIR COOLER SYSTEMS IN A DYNAMOMETER TEST CELL

1989-11-01

HISTORICAL

J1937_198911

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.

J1515_199506

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.

It is anticipated that this SAE Recommended Practice will be only one step in a comprehensive evaluation of the vehicle/transmission application. This document alone is not adequate “due care” to insure against high-speed seizure or other high-speed problems. The notes printed in bold print throughout the practice convey important information about the test itself or the results and should be considered carefully. All references to transmissions also apply to transaxles, except for the unbalance evaluation which applies only to rear-wheel-drive transmissions with propeller shaft output.
