Perspectives for using clean and energy efficient road vehicles

Abstract

The development of the economy promotes the growth of the travel market, creating challenges and opportunities for the development of the transportation system. Increased income and personal demands are also conditions for people to buy and use vehicles. Habits and needs are one of the main leading causes of environmental pollution, especially air pollution. This article focuses on the pollution caused by vehicles. The process of checking the quality of a car before it is put into production is very complicated, combining many inspection steps. This article is about the PEMS method that meets Euro 6 standards, should be widely applied in the future not only for passenger cars but also for heavy vehicles and others. According to the measurements, Volkswagen Golf met the Euro 6b limits for the NEDC and PEMS test in lighter conditions. Detected values were well below the limit value. Skoda Octavia is well below the limit value for carbon monoxide in the RDE-PEMS test; however, NOx emissions were 2-3 times higher than in the NEDC test. Emissions of vehicles in the laboratory test are different from the actual environment, so the use of PEMS for vehicle testing is necessary.
