长城汽车召开绿静2.0T乘用车柴油动力媒体发布会（原文）“高效节能、绿色环保、静音舒适”，10月12日，长城汽车召开媒体发布会，宣布将GW4D20柴油发动机正式命名为绿静2.0T柴油发动机。这个国内第一款自己设计、自主研发的柴油发动机采用了双顶置凸轮轴、电控高压共轨、VGT增压中冷、EGR系统和气门间隙自动补偿器等5项先进技术，且在“排放、动力、噪音、低耗”上创造了四项国内第一，并达到国际领先水平。绿静2.0T柴油发动机达到欧IV排放标准，已通过了欧盟认证，其升功率指标可达55KW/L、升扭矩可达155Nm/L，动力达到同类型3.0L发动机水平，超过国内外同类产品10%以上。由于采用了VGT增压中冷技术，大大降低发动机的噪音，绿静2.0T搭载在哈弗H5上之后，驾驶室内平均分贝可达到45.3Db(A)，车内噪音优于国际知名品牌柴油车型，与汽油机相差不大。同时，此款发动机搭载在1.72吨的哈弗H5上，其整车综合油耗仅为百公里6.8L，相当于1.5L汽油轿车的油耗。该款柴油发动机将首先装配在哈弗H5欧风版、风骏高端皮卡上，今后还将陆续匹配在轻型商务车、中级轿车上。来自中央电视台、新华社、中国青年报、中国汽车报等20多家媒体记者出席了发布会。同时，会议还邀请了全国清洁汽车协调领导小组办公室专家组组长、“国家科技部863计划节能与新能源汽车”重大科技专项特聘专家、原中国汽车技术研究中心主任王秉刚，吉林大学内燃机工程系主任、中国汽车工程学会代用燃料汽车分会副主任、“国家863计划节能与新能源汽车”咨询专家李君，天津大学教授、博士生导师、中国热物理学会常务理事、汽车工程学会理事姚春德3位专家进行点评。译文：DieselPoweredPressConferenceheldbyGreetwallMotorsforits“GreenandQuiet2.0T”PassengerVehicleWithslogan”Highefficiencyandenergysaving,GreenEnvironmentalProtection,QuietandDrivingComfort”,OnOctober12th,GreetWallMotorsheldthepressconference,declaringthatitsGW4D20dieselenginewillbeofficiallycalledGreenandQuiet2.0Tdieselengine.China’sfirsttypeofself-designeddieselengineadoptedfiveadvancedtechnologieswithDualoverheadcamshafts,Electricallycontrolledhigh-pressurecommonrail,VGTChargeInter-cooling,EGRsystemandself-Compensationdeviceforvalveclearance,Itscoretechnologyisresearchedanddevelopedindependently.Italsowonfirstplaceatfourtermson“displacement,power,dieselenginenoiseandlowconsumption”inthecountryandhadreachedleadinglevelthroughouttheworld.TheemissionresultsofGreen-Quiet2.0TdieselenginecanreachtheEuroIVstandardandhaspassedtheEUcertification.Thepowerperliterofthisenginereaches55KW,thetorqueperliterreaches155Nm,itspowerreachesthelevelof3.0Lengineofthesametypeandexceeds10%comparedtothesametypeofdomesticandoverseasproducts.OwingtotheintroductionoftheVGTChargeInter-coolingtechnology,thedieselenginenoisewasgreatlyreduced.WhenequippedonHavelH5,theaveragedecibelinthecabis45.3Db(A),whichisnotsignificantlydifferentwithgasolineengineandbetterthandieselmodelsofinternationalfamousbrand.Meanwhile,thecompletevehiclecomprehensiveoilconsumptionof1.72tonofhalvaH5equippedwiththisengineisonly6.8L/hundredkm,anequivalentofthatofa1.5Lgasolinecar.ThistypeofdieselenginewillbefirstassembledonHavarlH5EurostyleversionandWingleHigh-endPickupandwillprogressivelybeappliedtolightcommercialvehiclesandmiddle-classvehiclesinthefuture.Journalistsfrommorethan20mediaoutletsincludingCCTV,NewChinaNewsAgency,ChinaYouthDailyandChinaAutomotiveNewsjoinedthepressconference.Atthesametime,Threeexpertswereinvitedtomakecommentsontheconference,theyareWangBinggang---groupleaderofexpertpanelofofficeofcoordinatingleadinggroupofnationalcleanautomobile,specialinvitedexpertofstates863planenergySavingandNewEnergyVehicleKeyProgramofMinistryofScienceandTechnology,theoriginaldirectorofChinaAutomotiveTechnologyandResearchCenter.LiJun---directorofDepartmentofInternalCombustionEngineofJilinUniversity,deputydirectorofalternativefuelautomobilebranchofChina'sAutomotiveEngineeringSociety,consultingexpertofStates863PlanEnergySavingandNewEnergyVehicle.YaoChunDeProfessor,doctoralsupervisorofTianjinUniversity,standingdirectorofThermalPhysicalSociety,directorofAutomotiveEngineeringSociety.参考网址：http://www.gwm.com.cn/en/newsDetail_1256111095687_1287622427171.html
