ANSWERS TO QUESTIONS

Answer: Harmony with Phase-I with regard to LDV-PC is essential. As mentioned above main task is to move the existing HORIBA emission measurement system to the new place (Please refer to “Annex II of Minutes of the Site Visit” no. 1 or 2 in drawing-1). This HORIBA system must work with the new chassis dynamometer. Detailed information on Phase I is provided in Clarification No. I and Annex II of the Minutes of the Site Visit.

Question-4 Page 69 - Chassis dynamometer supplied in this project and mounted in the specified test cell will be used with the exhaust gas collecting, dilution and analyzing system purchased in the first phase of the Automotive Technology R&D Center project.

The emission analysis system supplied at the first phase of the project may not be suitable for the actual conditions required by the laboratory and some add-on's might be necessary for its integration. According to legislation the length of exhaust gas lines are limited.

We need detailed information about layout of equipment to be installed at phase 1. Where is the Emission analyzer installed? Where will the CVS system be installed?

Answer: Detailed information on Phase I is provided in Clarification No. I and Annex II of Minutes of the Site Visit.

Question-5 Page 69 - Air conditioning system of “acoustic room” will also be used for “LDV-PC TS room” to keep the ambient temperature and humidity between the limits specified in standards (for visualizing see the drawings 1 and 2 given in APPENDIX-I.)

The system foreseen for the acoustic room might be not prepared for the climatic conditions required for the LDV-PC TS according to the legislation (-7ºC). On the other hand, the A/C system for LDV/PC TS is included in pos. 1.1.3 As the LDV-PC TS is a cold chamber the air condition from acoustic cell can most likely not be used.

There are inconsistencies in this issue. Confirm and rectify. What means in this case air conditioning?

Answer: To use, if possible, the existing ventilation (conditioning) system of the acoustic room for the new test cell (no: 1 or 2 in the drawing 1- Annex II of Minutes of the Site Visit) may be used to keep the conditions (i.e. 20 - 30^oC, etc) in test cell during normal emission tests. The existing system is capable to keep the room temperature between 20 -30^o C during emission test circulating 30.000 m3/h air, 8.000 m3/h of which being fresh air. / Rooms for chassis dynamometer and for emission measurement system (no: 1 or 2 in the drawing 1) may be divided into two stages and the air conditioning systems can be placed there. For -7º C test a separate conditioning system must be supplied by contractor.

Question-6 Page 70 - Water and electricity will be supplied by the Automotive Division of ITU, but, if necessary, they will be brought to the system rooms and distributed to the equipment by contractor.

The definition of the supplies for this phase should include the interfacing between the services provided by the building and the test and measurement systems
