DIESEL ENGINE EMISSION MEASUREMENT PROCEDURE

1990-06-01
HISTORICAL
J1003_199006
This SAE Recommended Practice is intended for use as a test procedure to determine the gaseous emission levels of diesel engines. Its purpose is to provide a map of an engine's emissions characteristics which, through use of the proper weighting factors, can be used as a measure of that engine's emission levels under various applications. The emission results for hydrocarbons, nitrogen oxides, carbon monoxide, and carbon dioxide are expressed in units of grams per kilowatt hour (grams/brake horsepower hour) and represent the mass rate of emissions per unit of work accomplished. The emissions are measured in accordance with SAE Recommended Practices J177, J215, and J244 using nondispersive infrared equipment for CO and CO2, a heated flame ionization analyzer for HC, and a high performance NDIR or a chemiluminescence analyzer for NOx. All emissions are measured during steady-state engine operation.

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

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.

ENGINE TERMINOLOGY AND NOMENCLATURE—GENERAL

1995-06-28
HISTORICAL
J604_199506
This SAE Recommended Practice is applicable to all types of reciprocating engines including two-stroke cycle and free piston engines, and was prepared to facilitate clear understanding and promote uniformity in nomenclature. Modifying adjectives in some cases were omitted for simplicity. However, it is good practice to use adjectives when they add to clarity and understanding.

CONTINUOUS HYDROCARBON ANALYSIS OF DIESEL EMISSIONS

1970-11-01
HISTORICAL
J215_197011
The method presented is the current recommendation for the use of flame ionization detectors to determine the hydrocarbon content of diesel engine exhaust, or exhaust of vehicles using diesel engines, when operating at steady-state. The requirements of the associated sampling system and a general procedure for a continuous measuring method are presented.

MEASUREMENT OF CARBON DIOXIDE, CARBON MONOXIDE, AND OXIDES OF NITROGEN IN DIESEL EXHAUST

1970-06-01
HISTORICAL
J177_197006
The method presented applies to the analysis of the indicated constituents in diesel engine exhaust, or exhaust of vehicles using diesel engines, when operating at steady-state conditions. The measurements of carbon monoxide, carbon dioxide, and nitric oxide are based on continuous sampling and analysis by nondispersive infrared methods. A supplementary batch sampling, wet chemistry method is described for analysis of the oxides of nitrogen.

CRANKCASE EMISSION CONTROL TEST CODE

1964-06-01
HISTORICAL
J900_196406
The purpose of this code is to provide standard test procedures for crankcase emission control systems and/or devices. The procedures included are for determining: 1 The flow rate of the blowby of an engine. 2 The flow rates through the crankcase emission control system inlet and outlet. This code is written to cover crankcase emission control systems which are designed to reduce the emission of engine blowby gases to the atmosphere. The code includes the following sections: 1. Definitions and Terminology 2. Test Equipment 3. Test Procedures 4. Information and Data to be Recorded 5. Data Analysis 6. Presentation of Information and Data
