Diesel EmissionsTopic:Diesel Fuel QualificationPoint of Contact:Test Objective:Bob FanickPhone: (210) 522-2653Fax: (210) 522-3950The objective of this test is to qualify one fuel bycomparing resulting emissions against another acceptedfuel.Apparatus:The apparatus used is principally a DDC Series 60 HDDiesel engine. Other post-1990 engines can besubstituted.Test Procedure:Repetitive EPA hot start transient emission tests areperformed.Fuel Requirement:The fuel requirement for this test is 250 gallons of eachtest fuel.Duration:The duration of this test is from 7 to 10 days, with 20 hotstarttransient tests on each fuel.Test Results: Test results include quantification of HC, CO, NO x ,particulate, SOF, and SO4.A PASS/FAIL determination is made with regard to NO x ,particulate, and SOF as compared to reference fuel.Note:This procedure is recognized by CARB.2SOUTHWEST RESEARCH INSTITUTESan Antonio, TexasJuly 2010
Emissions Research and DevelopmentTopic:Point of Contact:Test Objective:Emissions EvaluationUsing EngineDynamometerVlad UlmetPhone: (210) 522-2Fax: (210) 522-3950Objectives for this test include:• EPA transient, modal tests• Emissions mapping• Certification, audit, compliance• Fuel/additives effects• Control technology developmentApparatus:Various test apparatus may be used, with a power rangeof 1 hp to 2,500 hp or more.Test Procedure:Fuel Requirement:Duration:Test Results:Any transient or steady state schedule may be followed.This includes U.S., European, Japanese, and othercertification tests.Gasoline, diesel fuel, liquefied petroleum gas, natural gas,alcohols, biofuels, and blends in varying quantities may becalled for in this test procedure.The duration of this test procedure depends on the testobjective. Typical duration for these emissions tests isfrom 20 minutes to 1 hour.Test results vary according to procedure/objective.Usually, regulated emissions, particulate matter, and fuelconsumption are reported. Sometimes smoke orunregulated emissions may be reported. Numerousoptions are available depending on specific client needs.Note:3SOUTHWEST RESEARCH INSTITUTESan Antonio, TexasJuly 2010
