The Vehicle Emissions Laboratory carries out combustion gas emissions tests on chassis benches for motorcycles and vehicles with diesel or Otto cycle engines. It acts in the area of bench tests for combustion engines, in the determination of gaseous and particulate emissions, durability for the evaluation of engine components, performance and fuel consumption.
TESTS PERFORMED *
Vehicles and motorcycles:
- Light-duty motor vehicles, with determination of hydrocarbons, carbon monoxide, nitrogen oxides, carbon dioxide and particulate matter in the exhaust gas (NBR 6601);
- Light motor vehicles, with evaluations in accordance with European, American and Japanese standards; and fuel consumption measurement (NBR 7024);
- Light motor vehicles, with determination of aldehydes and ketones contained in the exhaust gas by liquid chromatography in the DNPH method (NBR 12026);
- Light motor vehicles, with determination of unburned ethanol contained in the exhaust gas, by gas chromatography (NBR 15598);
- Emissions test on mopeds and motorcycles, chassis dynamometer (WMTC-/ECE/TRANS/180Add.2);
- Emissions test on mopeds and motorcycles, on chassis dynamometer (European Community Directive nº 97/24/EC);
- Testing with gaseous emissions measurements, pre- and post-catalysts to verify efficiency and development of catalysts and engines;
- Emission tests for the evaluation of fuels and additives;
- Research and development in regulated and non-regulated emissions through techniques such as HPLC, GC and GCMS and FTIR;
- Emission tests to assess the energy efficiency of the vehicle.
- Motorized road vehicles with exhaust gas analysis and determination according to ETC, ESC and ELR cycles (NBR 15634);
- Road vehicles, with engine test code for net effective power (NBR ISO 1585);
