PARTICULATES PROGRAMWP500

• Laurent FORTI
• Particulates meeting
• CONCAWE - January 2003

2
WP500 - IFP Activities

• Vehicle selection and preparation
• Fuels and lubricant
• Equipment and set-up
• Test protocol
• Test schedule

3
Vehicle selection
4 Different engine and post-treatment
technologies representative of EURO3 and may be
EURO4 levels

• Gasoline vehicles
• Renault Mégane II 1.6 l coupe (IDI)
• Citroen C5 2l HPI - 143 HP (DI).
• Diesel vehicles
• VW Golf TDI 1.9l - 100 HP
• Peugeot 307 2.0 l HDI - 110 HP
• Minimum mileage before test 5000 km

4
Vehicle preparation

• Change of the lubricant - 500 km of conditioning
  period
• Road load setup
• Change of the fuel

5
Equipment - Dilution system
Specific primary dilution system (IFP but
equivalent to Dekati)
Dilution outside the exhaust line to limit
pressure pulse effect and gas temperature.
Moreover, the probe can be entirely dismounted
for cleaning.
6
Dilution Ratio with Dekati system GOLF TDI - No
catalyst
Large variations of the dilution ratio (6 to 20)
7
Dilution ratio with IFP systemPeugeot 405 - No
catalyst
Less variations of the dilution ratio
8
Equipment - Material Set-up
Wet branch - SMPS - DGI - LQ1 - DC (diffusion
charger Matter Engineering) - CPC Dry branch -
ELPI after thermodenuder Set-up Similar to
the round robin set-up
9
Test protocol (Standard Particulate Protocol)

• Prior to the series of tests Assessment of
  thermodesorber losses
• Steady state 50 km/h, 3rd Gear - Dilution ratio
  set-up (10 minutes) and 120 km, 5th gear
• Sampling with all instrument in dry branch (ELPI,
  SMPS, CPC), then in wet branch
• 2 days by fuel (IFP constraints)
• 1st day
• Cold NEDC
• Hot NEDC
• Artemis Urban and Road
• 2nd day
• Steady state measurement (50 km/h and 120 km/h)
• Fuel change, vehicle conditioning, cold soak

10
Test protocol (Specific after-treatment systems)

• Particulate trap
• Standard tests Specific procedure to regenerate
  the trap before the series of tests (high speed
  and load)
• Specific tests Measurements during a
  regeneration phase under steady state measurement
  (high speed and load)
• NOx Trap
• Standard tests High load running before
  conditioning the vehicle (before the 3 EUDC) to
  remove the sulphate from the NOx trap.
• Study of the regeneration strategy and
  measurement of particulate emissions during
  regeneration

11
Fuel order

• From the lower to the higher sulphur content
• Gasoline G3 to G1
• Diesel fuel D5 to D2
• One repeat for one fuel (G3 and D5)

12
Test schedule

• Start the 20th of January
• 1 week preliminary tests
• 2 weeks with GOLF TDI
• 2 weeks with Renault Megane
• 3 weeks with Peugeot 307 HDI
• 3 weeks with Citroen C5 HPI
• End mid April
