Summary of Test Method4.1 The test operation involves use of a Mack E7-350 diesel engine with a warm-up, a 2 h flush for each test, and then a constantspeed and torque conditions that a

39、re held for the remainder of the test. Reference oil test length is 300 h. Non-reference oil testlength is 250 h.4.2 Oil samples are taken periodically and analyzed for viscosity increase.4.3 Engine rebuild frequency is based on the degradation of test parameters and is left to the discretion of the

40、 test laboratory.At rebuild, the power section of the engine is disassembled, solvent-cleaned, measured, and rebuilt, using all new pistons, rings,cylinder liners, and valve guides, in strict accordance with furnished specifications.4.4 The engine crankcase is solvent-cleaned, and worn or defective

41、parts are replaced.4.5 The test stand is equipped with appropriate accessories for controlling speed, load, and various engine operating conditions.5. Significance and Use5.1 This test method was developed to evaluate the viscometric performance of engine oils in turbocharged and intercooledfour-cyc

42、le diesel engines. Results are obtained from used oil analysis.5.2 The test method is used for engine oil specification acceptance when all details of the procedure are followed.6. Apparatus6.1 General Description:6.1.1 The test engine is a Mack E7-350 mechanically governed engine, P/N 11GBA77623 (s

43、ee Annex A5). It is anopen-chamber, in-line, six-cylinder, four-stroke, turbocharged, charge air-cooled, compression ignition engine. The bore and strokeare 124 mm by 165 mm, and the displacement is 12 L. The engine is rated at 261 kW at 1800 r/min governed speed (see SAEJ1995).6.1.2 The ambient lab

44、oratory atmosphere should be relatively free of dirt, dust, and other contaminants as required by goodlaboratory standards. Additionally, it is recommended that the atmosphere in the engine buildup area be filtered and controlled fortemperature and humidity to prevent accumulation of dirt or dust on

45、 engine parts. Uniform temperature control will also aid inmeasuring and selecting parts for assembly.6.1.3 Use the low sulfur reference diesel fuel shown in Table 1.6.2 The Test Engine:6.2.1 Mack Test EngineThe engine is available from Mack Trucks, Inc. A complete parts list is shown in Table A5.1.

46、6.2.2 Engine Cooling System:6.2.2.1 A new Mack coolant conditioner shown in Table A5.1 is required every test to limit scaling in the cooling system.Pressurize the system at the expansion tank to 103 kPa.TABLE 1 PC-9-HS Reference Diesel FuelProperty Test Method MinA MaxASulfur, mass % D2622 0.04 0.0
