Significance and Use |
5.1?This test method was developed to evaluate automotive lubricants effect on controlling valve-train wear and overall engine wear for overhead camshaft engines with direct acting bucket lifters. 5.2?Average intake lifter volume loss is used as a measure of an oils ability to prevent valve-train wear. 5.3?End-of-test oil iron concentration is used as a measure of an oils ability to prevent overall engine wear. Note 2:?This test method may be used for engine oil
specifications such as API SP, and ILSAC GF- 6A, and
GF-6B.

1. Scope |
1.1?This test method measures the ability of an engine crankcase oil to control valve-train wear in spark-ignition engines at low operating temperature conditions. This test method is designed to simulate extended engine cyclic vehicle operation. The Sequence IVB Test Method uses a Toyota 2NR-FE water cooled, 4 cycle, in-line cylinder, 1.5 L engine. The primary result is bucket lifter wear. Secondary results include cam lobe nose wear and measurement of iron (Fe) wear metal concentration in the used engine oil. Other determinations such as fuel dilution of the crankcase oil, non-ferrous wear metal concentrations, total fuel consumption, and total oil consumption, can be useful in the assessment of the validity of the test results.2 1.2?The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.2.1?ExceptionsWhere there is no direct SI equivalent such as pipe fittings, tubing, NPT screw threads/diameters, or single source equipment specified. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific warning statements are provided throughout this document as necessary in each particular section. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
