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 Recommended Practice establishes uniform laboratory techniques for the continuous and bag-sample measurement of various constituents in the exhaust gas of the gasoline engines installed in passenger cars and light-duty trucks. The report concentrates on the measurement of the following components in exhaust gas: hydrocarbons (HC), carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2), and nitrogen oxides (NOx). NOx is the sum of nitric oxide (NO) and nitrogen dioxide (NO2). A complete procedure for testing vehicles may be found in SAE J1094. This document includes the following sections: 1 Scope 2 References 3 Emissions Sampling Systems 4 Emissions Analyzers 5 Data Analysis 6 Associated Test Equipment 7 Test Procedures

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.

This SAE Recommended Practice provides information on procedures, tools, and fixtures useful in determining frictional torque measurement of radial lip oil seals. Information on the effect of various operational environments on oil seals are discussed and a means of calculation of power consumption of seals is provided.

This SAE Recommended Practice covers the dimensional and material requirements of rubber O-rings for automotive application and rectangular section rubber seal rings for automotive applications.

This SAE Recommended Practice defines flywheel configuration to promote standardization of flywheels for dry spring-loaded clutches. Clutches to fit flywheels with configurations per this document may not be commercially available. Availability should be ascertained prior to flywheel design Figure 1 and Table 1A.

The following is a list of the most common terminology used in describing hydraulic control systems. The hydraulic control system of an automatic transmission may include oil pumps, pressure regulator, governor, and control valves.

This SAE Recommended Practice is intended as a guide to the design and use of static and reciprocating elastomeric transmission seals. It has been prepared from existing literature, which includes standards, specifications, and catalog data of both 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 static and reciprocating elastomeric transmission seals.
