Agenda Item 4.
OIL #2, 56: CO2 family definition and Combined Approach

Presentation of ACEA document.

Will present results from further investigation in January.

ACEA means that the combined approach works for complete cycle and phases because the method is based on cycle energy.

EC question regarding phase specific values based on test of complete cycle.

Japan presents their position regarding combined approach.

Proposes to narrow applicable criteria or require additional midpoint test in the CS test.

ACEA proposes that instead of midpoint, the midpoint is TMH in one family and TML in a new family. Divide the nonlinear family in two families.

As a check of linearity the proposed method could work. The concept needs to be developed further regarding definition of the midpoint.

T&E proposes to combine the two proposals from Japan and ACEA to clarify which parameters that needs to be considered regarding phase specific values in the combined approach.
