1 Kompetenscentrum Förbränningsprocesser, KCFP Prof. Bengt Johansson Div. of Combustion Engines, Dept. of Energy Sciences

2 Kompetenscentrum Förbränningsprocesser, KCFP ett centrum för grundläggande studier av förbränning, både stationär och instationär 1/3 STEM, 1/3 Industri, 1/3 Lund Universitet, totalt minst 18 Mkr/år dvs. ca. 200 mkr omsatt Från 1/ ett centrum för motorförbränning Nu ca. 22 Mkr/år varav STEM 7 Mkr. Alla typer av förbränning skall studeras men fokus på den nya generationen med låg NOx, HCCI

3 Power capacity by Swedish combustion engines produced annually Volvo Trucks 2005: trucks and busses with average power of 400 kW= MW Volvo Cars 2004: cars with average power of 150 kW = MW Scania 2005: trucks with average power of 400 kW= MW Saab Automobile 2004: cars with average power of 150 kW = MW Total power capacity produced per year = MW (Total installed wind power in Sweden 404 MW)

4 HCCI research in the world

5 The first conference dedicated to HCCI

6 From keynote talk by Pierre Duret at IFP International Congress Nov

7 More recent

8 From keynote talk by Pierre Duret at IFP International Congress Sept Papers on HCCI the last 3.5 years

9 HCCI in Lund

10 Combustion activities in KCFP 1.Basic engine studies 2.Laser diagnostics 3.Combustion modeling - Chemical kinetics 4.Closed loop combustion control 5.Fuel effects

11 Per Amnéus Magnus Christensen Mattias Richter HCCI in Lund 1997

12 Olof Erlandsson Per Amnéus Magnus Christensen Mattias Richter HCCI-Projects 1999 Anders Hultqvist Jan-Ola Olsson

17 HCCI?

18 HCCI = Homogeneous Charge Compression Ignition  Kompressionsantändning av en förblandad bränsle/luft-blandning

19 Why HCCI?

20 HCCI Emissions vs. diesel HCCI 0,01 0,50 0,00 NOx PM * 0,05 USA 2007 AutoTechnology Oct. 2002, p 54

21 Brake fuel efficiency for 1.6 liter four cylinder VW engine

22 Clean locally or globally? Global emission (Greenhouse effect): CO2 i.e. fuel consumption Local emissions: NOx HC CO PM

23 Environmentally friendly ≡ no CO2?

24 A CO2 neutral alternative

25 Local Emissions ?

26 Some emission statistics from New York by the turn of the century… 200 m 3 liquid emissions per day 1000 ton solid emissions per day An army of tenths of thousands worked with transporting the emissions out from the city

27 Now time for the next step OttoDieselHCCI SACIPPC SACI= Spark Assisted Compression Ignition PPC= Partially Premixed Combustion

28 Partially premixed combustion, PPC Def: region between truly homogeneous combustion, HCCI, and diffusion controlled combustion, diesel Trade-off between NOx and HC, soot typical Combustion process not well known Soot the key feature

29 PPC potential
