2.0 DISCUSSION
Asaresultoftheongoinginvestigation intotheroot-cause oftherecentdieselgenerator crankcase explosions anareaofconcernis,whatimpactdoescombustion intakeairtemperature haveondieseloperation.
Perthemanufacturers specifications thistestwillincreasecombustion intakeairtemperature towithinarangeof105-110'F.
Atthistemperature anengineanalyzerwillbeutilizedtomeasureparameters suchascylinderpeakfiringpressure, firingangleandhorsepower.
Areviewofthisdatawilldetermine iftheEDieselGenerator isproperlybalanced, Ifnecessary engineadjustments willbeperformed andanotherengineanalyzerdatacollection willbeperformed.
Thisprocesswillberepeateduntilthedieselisconsidered tobebalanced.
Uponobtaining abalanceddieseltheESWflowthruthedieselintercoolers willbeincreased andmeasureduntilcertainintakeairtemperatures areobtained.
FinallytheESWflowthroughtheintercoolers willbereturnedtoitsnormalstatus(i.e.,inletvalvefullopen)andanengineanalyzerrunwillbeperformed.
Thedatafromthisfinalanalyzerrunwillbecomparedtothepreviousanalyzerrunstodetermine thecharacteristics ofengineoperation withrespecttointakeairtemperature.
Presently theESWInletValvetotheEDieselGenerator Intercoolers isFullOpen.Therefore, bythrottling inthecloseddirection duringthistest,moreflowwillbedirectedtotheothercomponents suppliedbyESW.Asaresul't,ifaffected, theflowstoothercomponents suppliedbyESWwillbeconservatively affected.
