【国外标准】 Test Method for Evaluation of Automotive Engine Oils for Inhibition of Deposit Formation and Wear in a Spark-Ignition Internal Combustion Engine Fueled with Gasoline and Operated Under Low-Temperature, Light-Duty Conditions (Withdrawn 2003)

1.1 This test method is commonly referred to as the Sequence VE test2 and has been correlated with vehicles used in stop-and-go service prior to 1988, particularly with regard to sludge and varnish formation and valve train wear. It is one of the test methods required to evaluate oils intended to satisfy the API SJ performance category.1.2 The values stated in either inch-pound units or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in parentheses when combined with inch-pound units. Some of the figures and forms have identical numerical designations, but with the letter M following the numerical designation: these are alternative figures and forms that contain SI units.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 7.7, 7.8.9.6, 7.8.13, 7.10.2, 7.10.3.2(c), 8.3.4.2, 8.4.4.3, 8.4.5.2, 9.3.4.4, 9.6.1.2, 12.1.1.5, 12.1.4.5, 12.2.1, 12.2.1.5, Fig. A3.6, and Annex A8.1.4 Table of Contents: Section 1Referenced Documents 2Terminology 3Summary of Test Method 4Significance and Use 5Apparatus-General Description 6Apparatus-The Test Engine 7Sequence VE Test Engine Parts Kit 7.1Required New Engine Parts 7.2Reusable Engine Parts 7.3Specially Fabricated Engine Parts 7.4Special Engine Measurement and Assembly Equipment 7.5Miscellaneous Engine Components-Preparation 7.6Solvents and Cleansers Required 7.7Assembling the Test Engine-Preparations 7.8Assembling the Test Engine-Installations 7.9Engine Installation on the Test Stand 7.10Engine Fluids-Supply/Discharge Systems 8Intake Air 8.1Fuel 8.2Engine Oil 8.3Coolants 8.4Measurement Instrumentation 9Temperatures 9.1Pressures 9.2Flow Rates 9.3Fuel Consumption 9.4Speed and Load 9.5Exhaust Gas 9.6Miscellaneous Laboratory Equipment 10Test Stand Calibration 11Verification 11.1Unacceptable Calibration Tests 11.2Test Stand Modifications 11.3Reference Oil Accountability 11.4Test Numbering System 11.5Procedure 12Pre-Test Procedure 12.1Engine Operating Procedure 12.2Periodic Measurements and Functions 12.3Special Maintenance Procedures 12.4Diagnostic Data Review 12.5End of Test Procedure 12.6Interpretation of Results 13Parts Rating Area-Environment 13.1Sludge Ratings 13.2Varnish Ratings 13.3Clogging 13.4Sticking 13.5Wear Measurements 13.6Assessment of Test Validity 14Average Exhaust Gas NOX Levels 14.2Used Oil Analyses 14.3Blowby Flow Rate 14.4Intake Manifold Vacuum 14.5Fuel Consumption Rate 14.6Oil Consumption 14.7Report 15Report Format 15.1Special Forms for Automated Data Acquisition 15.2Standard Report 15.3Calibration Test Report 15.4Precision and Bias 16Precision 16.1Bias 16.2ANNEXESSpecial Service Tools for the Test Engine A1External Oil Heat Exchanger Cleaning Technique A2Detailed Specifications and Photographs of Apparatus A3Engine Part Number Listing A4Operational Data Log Sheets A5Rating Worksheets A6Final Report Forms and Photographs A7Safety Precautions A8Automatic Data Acquisition A9Oakite 811 Monitoring Program A10Test Precision-Reference Oils A11Control Chart Technique for Severity Adjustment A12Statistical Equations for Mean and Standard Deviation A13Data Dictionary A14One-half Millimetre Oversize Piston Modifications A15Required Inspections and Operations for Reuse of Cylinder Heads A16APPENDIXESEngine Measurement Sheets X1Sources of Materials and Information X2Analysis of Phillips "J" Fuel (Batch 26) X3Theoretical Exhaust Gas Relationships-Phillips "J" Fuel X4Description of Scott Quarterly Gas Audit Service X5
