Modern methods of testing vehicles for environmental safety

Introduction (problem statement and relevance). The problem of reducing emissions of harmful substances (HS) by road transport plays a paramount role in solving the environmental problem in the advanced countries of the world.

The purpose of the work was to develop a route according to the RDE test methodology (tests for emissions in real operating conditions) to determine the fuel consumption and emissions values of worked out harmful substances in exhaust gases of vehicles, close to real operating modes.

Methodology and research methods. The analytical method of research was applied.

Results. Information was provided on current regulatory documents, requirements and test methods, together with the trends in the development of new test methods for assessing the environmental and fuel-economic characteristics of vehicles. Comparative parameters/modes of various laboratory tests driving cycles were presented, together with test route requirements and speed limits in real road conditions. The expediency of introducing and applying new test methods to obtain real data on fuel consumption was noted.

Practical significance. The direct full-scale route testing on the ground with the application of the PEMS gas analysis complex confirmed the possibility of using the RDE test methodology technique on the territory of the Russian Federation virtually all year round.
