EMISSION TEST DRIVING SCHEDULES

1991-06-01
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.

Reporting on Emission Testing for In-Use Light-Duty Trucks and Passenger Vehicles

2001-06-27
CURRENT
J1712_200106
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.

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.

J335_202010
This SAE Recommended Practice establishes equipment and test procedures for determining the performance of spark arrester exhaust systems of multiposition small engines (<19 kW) used in portable applications, including hand-held, hand-guided, and backpack mounted devices. It is not applicable to spark arresters used in vehicles or stationary equipment.

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.

Flywheels for Single-Plate Spring-Loaded Clutches

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.
