3. Logistics The transported RR equipment package comprises
Three (3-4) pallets and the vehicle
About 650 kg kg
Fuel will be transported separately to each lab
Each lab transports the package to the following lab
Table of laboratories will follow
Each lab covers the transportation costs
Each lab should inform JRC about the
Condition of the RR equipment at arrival

5. Objectives Objectives of the RR is to
To evaluate the measurement uncertainties of the PMP- 23nm and PMP-10nm systems
Assess the need of a catalytic stripper (CS)
To obtain data for evaluation of sub23nm fraction of modern engines

6. Test protocol
Tests are aimed to be conducted within 3 measurement days
3 cold WLTCs and 5 hot WLTCs
cold start WLTCs
1 steady speed test
The test results are used for
Evaluating PN10 measurement possibilities with existing LabPMP
Gathering PN23/PM10 data for vehicles
Compare results between the laboratories
The steady speeds are included in the protocol to
Compare sub23nm fractions from the steady points at different labs.
Stability or setup differences can be better understood

7. About steady speed test
Example speed/gear - compinations
Selected stable
periods
About steady speed test
The steady speed test protocol
Warm up the engine to oil temperature above 80 °C.
When the oil temperature is reached, start WLTC cycle
Keep the speed/gear compination steady
Always change to following speed- gear combination 10 s before phase ends

11. Questions to PMP RR labs
What other vehicles are you going to measure (MPI, GDI, GPF, DI, CNG, Hybrid GDI/MPI/DI) ?
Can you run test cycles at -7 °C dynamometer room temperature?
Any other suggestions for the RR?
