Summary of Test Method4.1 The test operation involves use of a Volvo/Mack D13/MP8 diesel engine with Exhaust Gas Recirculation (EGR). Awarm-up and a 1 h break-in are followed by a single-phase testconsisting o

36、f 360 h at 1500 r/min and fuel flow of 68.0 kg/h.4.2 Take oil samples periodically and analyze for viscosityincrease, oxidation, and wear metals content.4.3 Rebuild the engine prior to each test. Disassemble,solvent-clean, measure, and rebuild the engine power sectionusing all new pistons, rings, cy

37、linder liners, and connecting rodbearings, in strict accordance with furnished specifications.4.4 Solvent-clean the engine crankcase and replace worn ordefective parts.4.5 Equip the test stand with appropriate accessories forcontrolling speed, fuel flow, and various engine operatingconditions.5. Sig

38、nificance and Use5.1 This test method was developed to evaluate the oxida-tion resistance performance of engine oils in turbocharged andintercooled four-cycle diesel engines equipped with EGR andrunning on ultra-low sulfur diesel fuel. Obtain results fromused oil analysis and component measurements

39、before andafter test.5.2 The test method may be used for engine oil specificationacceptance when all details of the procedure are followed.6. Apparatus6.1 General Description:6.1.1 The test engine is a Volvo/Mack D13/MP8, electroni-cally controlled fuel injection with six electronic unit injectors.I

40、t is an open-chamber, in-line, six-cylinder, four-stroke,turbocharged, charge air-cooled, and compression ignitionengine.6.1.2 The ambient laboratory atmosphere shall be relativelyfree of dirt and other contaminants as required by goodlaboratory standards. Filtering air, controlling temperature, and

41、controlling humidity in the engine buildup area helps preventaccumulation of dirt and other contaminants on engine partsand aids in measuring and selecting parts for assembly.6.2 Test Engine:6.2.1 Volvo T-13 Test EngineThe engine is available fromTEI. A list of test parts to be replaced for each tes

42、t is shown inTable A6.1. Use test parts on a first-in/first-out basis. Acomplete engine parts list is available from the TMC website.6.2.1.1 The engine should be mounted with the flywheelperpendicular to the floor and tilted 4 toward the intakemanifold side of the engine.6.2.2 Engine Cooling System:

43、6.2.2.1 Use a new Volvo coolant filter shown in Table A6.1,every test, to limit scaling in the cooling system. Pressurize thesystem at the expansion tank to 103 kPa. Use the coolantdescribed in 7.3.1.6.2.2.2 Remove the thermostat and replace it with a sleeve(P/N 21474103) and seal (P/N 1549651).6.2.

44、2.3 Use a closed-loop, pressurized external engine cool-ing system composed of a heat exchanger, reservoir, andwater-out temperature control valve. The system shall preventair entrainment and control jacket temperatures within thespecified limit. Install a sight glass between the engine and thecooli

45、ng tower to check for air entrainment and uniform flow inan effort to observe and prevent localized boiling.6.2.2.4 Use a closed-loop, pressurized external EGR cool-ing system composed of a heat exchanger, reservoir, andcoolant-out temperature control valve. The system shall pre-vent air entrainment

46、 and control jacket temperatures within thespecified limit. Install a sight glass between the EGR coolerand the cooling tower to check for air entrainment and uniformflow in an effort to observe and prevent localized boiling. Thecoolant flow direction is to be parallel (concurrent) with theEGR gas f

Circulate oil through the tank with anauxiliary pump. The system schematic is shown in Fig. A5.1.The supply line to the tank from

48、the sump is to have an insidediameter of 16 mm. The return line from the tank to the sumpis to have an inside diameter of 12 mm. Use a vent line with aminimum inside diameter of 13 mm. Return line from externaloil vessel connected to center of compressor block-off plate.Refer to Fig. A5.2. Vent of e

49、xternal oil vessel connected tocylinder head cover between cylinder 1 and cylinder 2 (seeattached). Max length of supply and return line combined: 5.4m (18 ft).6.2.3.2 Use a front mount steel oil pan (P/N 21585801) withgasket (P/N 21293367). Remove the oil level sensor. Locatethe auxiliary oil system suction line on the exhaust side of theoil pan, down from the oil pan rail 245 mm, and back from thefront of the pan 157 mm. Refer to Fig. A5.3. Connect theauxiliary oil system return line to the air compressor block offplate on the rear timing gear cover. Connect
