CURRENT
J215_200210
The method presented is the current recommendation for the use of flame ionization detectors to determine the hydrocarbon content of diesel engine exhaust, or exhaust of vehicles using diesel engines, when operating at steady-state. The requirements of the associated sampling system and a general procedure for a continuous measuring method are presented. This SAE Recommended Practice provides for the continuous measurement of the hydrocarbon concentration in diesel exhaust.

Crankcase Emission Control Test Code
2012-01-23
CURRENT
J900_201201
The purpose of this SAE STandard is to provide standard test procedures for crankcase emission control systems and/or devices. The procedures included are for determining: a. The flow rate of the blowby of an engine; b. The flow rates through the crankcase emission control system inlet and outlet. This code is written to cover crankcase emission control systems which are designed to reduce the emission of engine blowby gases to the atmosphere. The code includes the following sections: 3. Definitions and Terminology; 4. Test Equipment; 5. Test Procedures; 6. Information and Data to be Recorded; 7. Data Analysis; 8. Presentation of Information and Data.

HISTORICAL
J1506_199106
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.

Engine Testing with Low-Temperature Charge Air-cooler Systems in a Dynamometer Test Cell
2011-09-06
CURRENT
J1937_201109
The methods presented in this SAE Recommended Practice 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.

IMPACT OF ALTERNATIVE FUELS ON ENGINE TEST AND REPORTING PROCEDURES
1995-06-28
HISTORICAL
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.

INSTRUMENTATION AND TECHNIQUES FOR EXHAUST GAS EMISSIONS MEASUREMENT
1971-06-01
HISTORICAL
J254_197106
This SAE Recommended Practice establishes uniform laboratory techniques for the continuous and grab sample measurement of various constituents in the exhaust gas of the gasoline engines installed in passenger cars and light trucks. The report concentrates on the measurement of the following components in exhaust gas: hydrocarbons (HC), carbon monoxide (CO), carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2), and oxygen (O2). This recommended practice includes the following sections: 1. Introduction 2. Definitions and Terminology 3. Sampling and Instrumentation 4. Associated Test Equipment 5.

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.

Manual Transmissions and Transaxle High-speed Lubrication, Unbalance, and Seizure Evaluation
2011-09-06
CURRENT
J2132_201109
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.

NONMETALLIC GASKETS FOR GENERAL AUTOMOTIVE PURPOSES
1963-04-01
HISTORICAL
J90A_196304
These specifications for SAE J90 are intended to define the basic properties of commercial nonmetallic gasketing materials commonly used in automotive applications. These include materials composed of asbestos or other inorganic fibers, cork, or cellulose or other organic fibers, in combination with various binders or impregnants. Rubber compounds without fibrous or cork reinforcement are not included since they are covered in SAE Standard, Specifications for Elastomer Compounds for Automotive Applications—SAE J14, and in ASTM D 735-61T. Although the test methods and values are designed to describe the basic properties of the material in each category, they do not define all of, the properties which govern gasket performance. Caution should, therefore, be exercised in using these specifications as a basis for the selection of materials.
