3.0L V6 TFSI engineof EA839 series  \nSelf Study Programme 655  \nFor internal use only.  \nThe new 3.0LV6 TFSI engine of the EA839 series supersedes thepreviously installed 3.0LV6 TFSI EA837.It will initially be used inthe Audi S4(type 8W),where it provides better performance andfuel economy than its predecessor.  \nThe engine will be available in several performance classes,eitheras a mono-turbo or a biturbo,in Audi models and also in othergroup models.  \nThe development goals were not only to improve fueleconomy forendusers,but also to meet the mandatory emission limits in allmarkets.This is achieved by a range of modifications includingreduced friction,innovative thermal management,lightweightdesign and cutting-edge engine management technology.  \nLearning objectives of this self study programme:  \nThis self study programme describes the design and function ofthe fourth-generation 3.0LV6 TFSI engine of the EA839 series inthe Audi S4(type 8W).  \nAfter you have completed this self study programme you will beable to answer the following questions:  \nOther innovative features of the new V6 engine are:  \n>Thermostat controlled oil circuit  \n>Cylinder heads with integrated exhaust manifold and \"Hot SideInside\"(HSI)technology  \n>New timing assembly with balancer shaft  \n>New combustion process(Miller cycle)with central injectorconfiguration  \nThis SSP contains QR codes which you canuse to access additional interactive content(refer to page 58).  \n655-002  \n>What are the differences between the EA839 and the EA837?  \n>Which structural design measures are used to achieve light-weight design?  \n>How do the oil supply and engine cooling systems work?  \n>What are the special features of the air supply system?  \n>How do the new injection process and the engine managementsystem work?  \nContents  \nIntroduction  \nEngine description and special features ………………………………………………………………………………………………………………………………………………………………………………………………………………4  \nSpecifications_
