This report is focused on testing instrumentation and demonstration of multi gas exhaust measurements in cold climate. The multi gas measurements are possible to use in mobile field condition as well as in stationary condition on a routine basis. The objective is to demonstrate how cold start measurements (without exhaust gas flow measurement) can be performed with FTIR (Fourier Transform Infra Red spectroscopy), The main questions are how to assemble and maintain system/systems for routine measurements by the testing companies which fulfils the requirement of the car manufactures. Cold start testing is in certification performed with a sophisticated dynamometers system to obtain the standard heating rates for the system (including the catalyst). The catalyst starts to work at a certain temperature. Emissions emitted before this temperature gives the cold start emissions. The easiest way to measure cold start emissions would be to measure the emissions at idling. If this is not sufficient to give usable data for the car manufactures a brake system would be required, which is very costly. A cheaper system would be to use an onboard measurement system. Therefore is the major question; is it required to have a brake system to be able to obtain usable emission data for the car manufactures and if yes, what is the requirement on the dynamometer system. Or could a mobile system fulfil the requirements and obtain acceptance for real driving tests. This report discusses three different options of which option 1 and 2 is movable and option 3 is stationary; - 1. Mobile measurement system - cold start emission testing at idling. - 2. Mobile measurement system with the FTIR on-board. - 3. Vehicle test system using a dynamometer system. It demonstrates also a cold start emission test.
