DIESEL SMOKE MEASUREMENT PROCEDURE

1988-09-01

HISTORICAL

J35_198809

The 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.

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.
