Standard Test Method for Evaluation of Engine Oil Aeration Resistance in a Caterpillar C13 Direct-Injected Turbocharged Automotive Diesel Engine
 N D8047

Annotation

This test method evaluates an engine oil’s resistance to aeration in automotive diesel engine service. It is commonly referred to as the Caterpillar-C13 Engine-Oil Aeration Test (COAT). The test is conducted under high-engine-speed (1800 r ?min), zero-load conditions using a specified Caterpillar 320 kW, direct-injection, turbocharged, after-cooled, sixcylinder diesel engine designed for heavy-duty, on-highway truck use. This test method was developed as a replacement for Test Method D6894.

NOTE 1—Companion test methods used to evaluate engine oil performance for specification requirements are discussed in the latest revision of Specification D4485.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

Exception—Where there is no direct SI equivalent, for example, screw threads, national pipe threads/diameters, and tubing size.

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. See Annex A2 for general safety precautions.

This test method is arranged as follows:
