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.

MEASUREMENT OF INTAKE AIR OR EXHAUST GAS FLOW OF DIESEL ENGINES
1971-05-01
HISTORICAL
J244_197105
The detailed recommendations have been limited to three metering systems and the associated equipment required to measure diesel engine gas flows at steady-state operating conditions. Accuracy goals are established, and the procedures and equipment are proposed as required to obtain desired measurement accuracy.

HISTORICAL
J244_199208
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.

Instrumentation and Techniques for Exhaust Gas Emissions Measurement
2011-06-10
CURRENT
J254_201106
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

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.
