Spark Arrester Test Procedure for Large Size Engines

2020-10-06

CURRENT

J342_202010

This SAE Recommended Practice establishes equipment and procedures for the evaluation of the effectiveness and other performance characteristics of spark arresters or turbochargers used on the exhaust system of large engines normally used in a railroad locomotive, stationary power plant, and other similar applications. This document does not cover applications requiring flame arresting, exhaust gas cooling, or isolation from explosive gases. Two test methods are presented: a laboratory test using ambient air (cold test) and an engine test using exhaust gases (hot test). The hot test is preferred. Arresters tested by the provisions of this document can be expected to perform as tested when tilted no more than 45 degrees from their normal position. Test results from a spark arrester or turbocharger evaluated by the hot test can be applied to different engines of similar design, provided the data shows it to be effective in the applicable flow ranges.

CURRENT

J1033_201206

This SAE Recommended Practice applies to any internal combustion engine which can utilize SAE No. 6 thru SAE No. 00 size flywheel housing. It provides instructions for correcting flywheel housing bore runout readings which are influenced by crankshaft bearing clearance. Limits for bore and face runout are specified in the various SAE Standards and Recommended Practices covering flywheels and flywheel housings.

Flywheels for Single-Plate Spring-Loaded Clutches

2012-05-31

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.

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.

Impact of Alternative Fuels on Engine Test and Reporting Procedures

2011-09-06

CURRENT

J1515_201109

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.

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.

Measurement of Intake Air or Exhaust Gas Flow of Diesel Engines

2011-06-13

CURRENT

J244_201106

This procedure establishes recommendations on the measurement of diesel engine intake air flow under steady-state test conditions. The measurement methods discussed have been limited to metering systems and associated equipment found in common usage in the industry, specifically, nozzles, laminar flow devices, and vortex shedding. The procedure establishes accuracy goals as well as explains proper usage of equipment. The recommendations concerning diesel engine exhaust mass flow measurements are minimal in scope.
