Introduc1on  –  Brazilian  Legisla1ons  

 Brazilian  future  emission  legisla:on  will  enforce  a  decay  on  CAFE  InovarAuto:  decree-­‐law  that  imposes  new  limits

Introduc1on  –  Fuel  Par1culari1es  

 Brazilian  market  requires  Flex  Fuel  engine  opera:on    The  engine  should  work  properly  with  mixtures  between  E18  and  E100    Ethanol  has  several  different  proper:es  in  comparison  with  regular  pure  gasoline

Energe1c  Density  

Lubricity  and  Oil  dilu1on  

Allows  higher  spark  advances  and  increased  compression  ra:os  

Higher  H/C  ra:o  is  beneficial  for  emissions    

Upper  vaporiza:on  enthalpy  leads  to:    •  Enhanced  engine  

breathing  •  cold  start  difficul:es  

Diminishes  unburned  emissions  and  decreases  the  Lower  Hea:ng  Value  

Decrease  in  the  Lower  Hea:ng  Value  requires  higher  fuel  mass  delivery  

Higher  oil  consump:on  and  poor  lubricity  features  for  ethanol  

èLeads  to  engine  wear  intensifica:on

Main  Conclusions  

 Has  to  to  get  o  good  state  of  the  art  with  E100  fuel      

Understand  physical  and  chimical  phenomena  concerned    To  enfase  remarkable  proper:es  for  combus:on    

   E100  specific  features  can  brings  significant  addicional  CO2  benefit  to  gasoline  engine  technology  as  :    

  Miller  cycle      EGR    Variable  compression  ra:o    

  .....     Low  water  content  ethanol  introduc:on    can  be  an  addicional  

opportunity  for  fuel    consump:on  reduc:on  .
