Opis:: The paper presents results of the pollutants emission measurements from the exhaust system of the forklift truck as a representative of the off-road mobile machinery operating in real conditions. Directive 96/68/EC does not include spark ignition engines with maximum power output greater than 19 kW. In order to check the emission characteristics of the off-road mobile machinery equipped with such engine, the tests have been carried out of the H16T type forklift truck, manufactured by Linde company, fuelled with LPG. The portable analyzer (PEMS) Semtech-DS by Sensors was used for the measurements. It allowed making the necessary calculations to determine the road - test pollutants emission as a function of time. The tests included emission testing in stationary conditions and roadside emission testing of the forklift truck. The paper contains illustrations with many figures and tables showing CO, CO2, THC and NOx emissions versus speed, time and fork load of the tested machine. It contains discussion on the possibility of road emission measurements expressed in g/km for off-road machineries as well as usefulness of these measurements using portable emission measurement systems for the off-road machinery.

Tytuł:: Exhaust emission from vehicles under real road traffic conditions - a new chance for PTI

Opis:: The paper presents regulations and methods of testing emissions of exhaust toxic components from vehicles, particularly with respect to research methods under real road traffic conditions. In Europe, legal regulations determine emission values of the exhaust toxic components: carbon monoxide CO, unburned hydrocarbons HC and hydrocarbons released by evaporation (VOC - Volatile Organic Compound), nitrogen oxides NOx, and also PM emitted with the exhaust gasses. Emission of the harmful substances from the vehicles is tested on the chassis dynamometer, and the combustion engines them, on engine test bench. Due to a high cost of the test equipment and complexity of the tests, it is possible to use one measuring system, for both types of stands. Basic EU Directives and UN-ECE Regulations contain rules on conducting the aforementioned tests together with the regulations for the measuring equipment. In the beginning of 2005 in Europe the introduction of a new set of regulations began be introduced, concerning emissions from the M1 and N1 category vehicles. They are called Euro IV (currently obligatory) and Euro V (introduced in 2008). New regulations introduced not only more stringent requirements for the vehicles they refer to, but also for the research laboratories as far as the equipment level and research methods are concerned. Compliance with these requirements is being verified during type approval of vehicles, conformity of production (COP), and in-service conformity.
