5.1 This test method was developed to evaluate automotive lubricant’s effect on controlling cam lobe wear for overhead valve-train equipped engines with sliding cam followers. 1.1 This test method measures the
ability of crankcase oil to control camshaft lobe wear for
spark-ignition engines equipped with an overhead valve-train and
sliding cam followers. This test method is designed to simulate
extended engine idling vehicle operation. The Sequence IVA Test
Method uses a Nissan KA24E engine. The primary result is camshaft
lobe wear (measured at seven locations around each of the twelve
lobes). Secondary results include cam lobe nose wear and
measurement of iron wear metal concentration in the used engine
oil. Other determinations such as fuel dilution of crankcase oil,
non-ferrous wear metal concentrations, and total oil consumption,
can be useful in the assessment of the validity of the test
results.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 Exceptions—Where 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 and health practices and determine
the applicability of regulatory limitations prior to use.
