The latest legislation regarding the reduction of harmful exhaust emissions, greenhouse gases and fuel consumption determines not only maximum permissible emissions factors, but also emissions testing methods and laboratory design and additionally leads to the development of new research methods. BOSMAL has risen to meet these challenges by investing in an updated, state-of-the-art emissions testing laboratory, housed within a climate chamber and in parallel investing in a completely new laboratory designed with incoming and future legislative requirements in mind. This paper presents BOSMAL’s improved M1/N1 vehicular emissions and fuel consumption laboratory in a climatic chamber and BOSMAL’s standard chamber for the testing of vehicles in accordance with European Union, US and Japanese standards. The specifications, capabilities and design features of the sampling, analysis and development research possibilities and climate simulation systems are presented and discussed in relation to the increasing drive for cleaner, light duty road vehicles (including hybrids and electric vehicles). The recently-renovated laboratory with extended standard temperature range and the laboratory with climatic chamber are described in the context of the newest European Union legislation on the emission in the range of Euro 6d testing requirements. The laboratories permit BOSMAL’s engineers to compete in the international automotive arena in the development of new, more ecologically friendly and increasingly fuel efficient vehicles.
