Comprehensive Testing of Diesel and Gasoline Vehicles Under CONCAWE LD Program

This report details the vehicle testing conducted by Shell Global Solutions as part of the CONCAWE LD Programme. It includes assessments of two Euro 3 diesel vehicles (VW Golf 1.9 TDI and Peugeot 607 2.2 HDI with DPF) and two gasoline vehicles (Renault Megane 2.0 IDE and Citroen C5 2.0 HPI). Testing utilized various fuel types and emission measurement equipment, showcasing results on regulated emissions like PM, NOx, CO, and HC. The comprehensive data is summarized in a detailed format for analysis by fuel number and testing conditions.

  2. CONCAWE LD Programme • Test Facility • Tests Performed by Shell Global Solutions in the UK • Test Vehicles • Two diesel vehicles (Euro 3):VW Golf 1.9 TDIPeugeot 607 2.2 HDI with DPF • Two Gasoline vehicles (Euro 3):Renault Megane 2.0 IDE (stoichiometric DI)Citroen C5 2.0 HPI (Lean-burn DI) • Test Fuels • Diesel: D2 (280 mg/kg S), D3 (38 mg/kg S), D4 (8 mg/kg S), D5 (Swedish Class 1) and D6 (340 mg/kg S – Euro 3) • Gasoline: G1 (143 mg/kg S), G2 (45 mg/kg S) and G3 (6 mg/kg S) Each fuel to be tested three times (3 blocks) with randomised test order.

  3. CONCAWE LD Programme • Daily Test Schedule • Cold NEDC (1180 s) • Hot NEDC (1180 s) • Artemis Urban (993 s) • Artemis Road (1082 s) • Artemis Motorway 130 km/h (1068 s) • 120 km/h Road-Load (600 s) • 50 km/h High-Load (600 s) • 50 km/h Road-Load (600 s) • 50 km/h Road-Load with High Dilution [W1] (600 s) • Fuel Change • Pre-condition Monday – Data processing and Pre-condition Tuesday to Friday – Full Test Days

  4. CONCAWE LD Programme • Sampling System and Instrumentation • Full Particulates system: • Dekati Porous-Tube dilutor with ageing chamber. • Dekati Ejector dilutors (on Wet and Dry branches) • Dekati Thermodesorber • TSI SMPS (3071A with 3022A CPC) – steady state only • TSI CPC (3022A) • Dekati ELPI • Dekati ASMO • Dekati DGI • CO2 analysers (three) for DR calculation • Horiba 9000 Emissions System

  6. CONCAWE LD Programme - Status • VW Golf 1.9 TDI • Triplicate Tests on 5 fuels completed • Additional tests complete- Thermodesorber tests with ELPI and SMPS- ELPI sampling from CVS • Peugeot 607 2.2 HDI with DPF • Triplicate Tests on 5 fuels completed in January 2003 • Tests on two Gasoline vehicles to follow after transfer of equipment to Gasoline emissions dynamometer. • 9 test days (3 fuels) per vehicle

  7. CONCAWE LD Programme - Results • Data summarised in to single sheet per vehicle: • 144 columns of data covering: • Test number, date, fuel etc. • Cycle/Phase time, distance, flow • Regulated emissions • DGI g/km (by stage and total) • ASMO cm2/km • ELPI #/km (by stage and total), mean particle size • SMPS #/km in 104 bins, <50nm, >50nm and mean particle size. • 3 rows for NEDC (cold and hot) • ECE, EUDC, Total Cycle • 1 row for each Artemis cycle and each steady-state test • Gives a total of 13 rows per test day

  8. Summary Results Sheet - Sample Columns: - 144 Columns to define tests and store summary results Rows: - One row per Test or Phase. - 13 Rows per Test day. Dropdown Boxes: - To select Column (Result) for plot. - To select Row (Test) for plot.
