استاندارد ASTM D6894 در خصوص Evaluation of Aeration Resistance of Engine Oils in Direct- Injected Turbocharged Automotive Diesel Engine

استاندارد ASTM D6894 در خصوص
Evaluation of Aeration Resistance of Engine Oils in
Direct- Injected Turbocharged Automotive Diesel Engine
 
نسخه ۲۰۱۳
۱۲ صفحه
 
Scope1.1 This test method was designed to evaluate an engine oil’s resistance to aeration in automotive diesel engine service.It is commonly referred to as the Engine Oil Aeration Test (EOAT). The test is conducted using a specified 7.3 L, directinjection, turbocharged diesel engine on a dynamometer teststand. This test method was developed as a replacement for Test Method D892 after it was determined that this bench test did not correlate with oil aeration in actual service. The EOATwas first included in API Service Category CG-4 in 1995.
۱٫۲ The values stated in SI units are to…

استاندارد ASTM D5966 در خصوص
Evaluation of Engine Oils for Roller Follower Wear
in Light-Duty Diesel Engine
نسخه ۲۰۱۳
۱۹ صفحه
 
Scope1.1 This engine lubricant test method is commonly referred to as the Roller Follower Wear Test. Its primary result, roller follower shaft wear in the hydraulic valve lifter assembly, hasbeen correlated with vehicles used in stop-and-go delivery service prior to 1993. It is one of the test methods required to evaluate lubricants intended to satisfy the API CG-4 performance category. This test has also been referred to as the 6.2 LTest.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,…
