The scope of the work done by this Laboratory includes:

•   Testing of the emission of exhaust gas pollutants from IC engines;

•   Carrying out of tests to standard CEC PF-023 on an engine test bench;

•   Determining of engine performance vs. speed curves (power and torque curves) for an engine installed in a vehicle;

•   Determining of fuel economy performance of a vehicle to the UDC/EUDC procedures or any other procedure to customer’s order;

•   Measurements of the intensity of pollutant emissions during the operation of IC engines, carried out to various test procedures;

•   Determining of IC engine performance curves, i.e. performance vs. speed curves, engine governor curves, and load curves (at constant speed);

•   Durability tests of engines installed in vehicles, to any customer’s test program;

•   Bench testing of IC engines of 2 ÷ 260 kW power ratings, inclusive of the measuring of basic performance characteristics, durability and reliability testing, and measuring of exhaust emissions of such engines;

•   Engineering design work on IC engines and their components;

•   Studies, analyses and expert’s opinions concerning IC engine-related issues;

•   Testing, research work, and engineering studies on automotive heat exchangers;

•   Testing of fuel injection equipment for compression-ignition (CI) and spark-ignition (SI) engines;

•   Bench testing of automotive vehicles of up to 3.5 t maximum permissible total mass on a chassis dynamometer, including the measuring of dynamic performance and exhaust emissions.

Selected R&D projects carried out at the Laboratory:

•   “Susceptibility of pollutant emissions and fuel consumption to the conditions of operation of a spark-ignition IC engine.”

Basic test equipment of the Laboratory:

•   Schenck 2WD chassis dynamometer for the testing of complete vehicles;

•   Automex engine test benches with eddy-current dynamometers of various sizes for the testing of engines at steady ambient conditions, provided with a computer control system making it possible to pre-program the test loads and to record the test results;

•   Integrated HORIBA automotive exhaust-gas analyser with extended CO, CO2, HC, NOx, and O2 contents measuring ranges, providing a possibility to carry out tests with both diluted and non-diluted exhaust gases;


•   HORIBA analyser for the testing of particulate matter (PM) emission;

•   Exhaust gas sampling and diluting system with a HORIBA CVS critical flow Venturi tube, to prepare the exhaust gas samples for analysis.

•   Schenck 2WD chassis dynamometer for the testing of complete vehicles;

•   AVL opacimeter model 439 for the measurements of exhaust smoke density;

•   AVL DiCom five-cell exhaust-gas analyser.

The Laboratory guarantees:

•   The tests mentioned above to be carried out by excellent specialists;

•   Professional test stands;

•   Modern monitoring and measuring equipment;

•   Short test completion periods.
