Thrust Washers – Design and Application

2011-06-13
CURRENT
J924_201106
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.

SPARK ARRESTER TEST PROCEDURE FOR MEDIUM SIZE ENGINES

1991-01-01
HISTORICAL
J350_199101
This SAE Recommended Practice establishes equipment and procedures for testing spark arresters used on medium-size, single-position internal combustion engines, normally used in transportable, stationary, and vehicular applications, such as highway trucks, agricultural tractors, industrial tractors, other mobile equipment, and motorcycles. This document provides two methods of testing (laboratory testing and engine testing) which may be used to evaluate a spark arrester. It also includes special requirements for screen type devices and an endurance test procedure for screen type spark arresters.

REPORTING ON EMISSION TESTING FOR IN-USE LIGHT-DUTY TRUCKS AND PASSENGER VEHICLES

2000-10-01
HISTORICAL
J1712_200010
This SAE Recommended Practice applies to the reporting of laboratory and test site data from the gaseous and evaporative emission tests of in-use light-duty trucks and passenger vehicles. This document describes the reporting of procedures, fuel specifications, and vehicle information necessary to compare the results of in-use tests. Any variations in vehicles, instrumentation, test equipment, or test program purpose should be adequately described.

Measurement of Fuel Evaporative Emissions from Gasoline Powered Passenger Carsand Light Trucks Using the Enclosure Technique

2000-12-07
CURRENT
J171_200012
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: a. A 1 h soak representing one diurnal cycle in which temperature of fuel in the vehicle's tank is raised from 15.6 to 28.9 °C (60 to 84 °F) b. A 17.9 km (11.1 mile) drive on a chassis dynamometer c. A 1 h hot soak immediately following the 17.9 km (11.1 mile) drive The method described in this document, commonly known as the SHED (Sealed Housing for Evaporative Determination) technique, employs an enclosure in which the vehicle is placed during the diurnal and hot soak phases of the test.

Manual Transmission and Transaxle Efficiency and Parasitic Loss Measurement

1999-08-30
HISTORICAL
J2453_199908
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.
