33、r Co. (see Table A2.3). New,weighed, intake valves are used to rebuild the cylinder head. Astandard engine oil is used for each test and a new oil filter isinstalled. The test engine is subjected to a rigorous qualitycontrol procedure to verify proper engine operation. To ensurecompliance with the t

34、est objective, data acquisition of keyparameters is utilized during test operation.4.3 The complete fuel system is flushed of test fuel from theprevious test. The fuel system is then filled with the new testfuel.4.4 The engine is operated on a cycle consisting of twostages. The first stage comprises

35、 operating the engine at 2000r/min and 30.6 kPa (230 mm Hg) manifold absolute pressurefor 4 min. The second stage comprises operating the engine at2800 r/min and 71.8 kPa (540 mm Hg) manifold absolutepressure for 8 min. Ramp time between each stage is 30 s andis independent of the stage times. The c

ApparatusNOTE 1Photographs are provided in Annex A1 depicting the requiredapparatus and suggesting appropriate design details.6.1 Laboratory Facilities:6.1.1 Engine and Cylinder Head Build-up and Measurement

41、AreaThe engine and cylinder head build-up and measure-ment area shall be reasonably free from contaminants andmaintained at a uniform temperature 63C (65F) between 10to 27C (50 to 80F).6.1.2 Engine Operating AreaThe engine operating areashould be relatively free from contaminants. The temperatureand

42、 humidity level of the operating area are not specified. Airfrom a fan can be routed on to the production air intake systemto assist in maintaining intake air temperature control.6.1.3 Fuel Injector Testing AreaThe fuel injector testingarea shall be reasonably free of contaminants. The humidityshoul

46、and ConfigurationAn example of a similartest stand configuration is described in Test Method D 5302(Sequence VE lubricant test method) since the same Ford 2.3L base engine is utilized. Mount the engine on the test stand sothat the flywheel friction face is 4.0 6 0.5 from the verticalwith the front o

47、f the engine higher than the rear. The engineshall be coupled directly to the dynamometer through adriveshaft. A test stand set-up kit is detailed in Table A2.1. Aspecial “dynamometer laboratory” wiring harness, Part No.DTSC.260.113.00E is required. Engine driven accessoriesinclude engine water pump

48、 and alternator or idler pulleyconfiguration as detailed in 10.7.9. If an alternator is installed,it is to serve only as an idler pulley; it is not to be energized.6.2.2 Dynamometer Speed and Load Control SystemThedynamometer used for this test is the Midwest 1014, 175horsepower, dry gap dynamometer

49、 or equivalent. Equivalencymeans that the dynamometer and dynamometer control systemshall be capable of controlling the procedural specifications asdetailed in Table 1 and the stage transitions to the specificationsin 13.4.3.1 and 13.4.4.1.6.2.3 Intake Air Supply SystemThe intake air supplysystem shall be capable of controlling moisture content, drybulb temperature, and inlet air pressure as specified in Table 1.See 10.7.8 and Fig. A1.4 for details of connection of thelaboratory intake air system to the engine.6.2.3.1 Intake Air HumidityDetermination of
