Measurement Delays and Modal Analysis for a Heavy Duty Transportable Emissions Testing Laboratory

Legislation regarding the reduction of harmful exhaust emissions, greenhouse gases and fuel consumption is one of the strongest drivers of development in automobile design. Emissions standards in the European Union (EU), USA and Japan determine not only maximum permissible emissions factors, but also emissions testing methods and laboratory design. BOSMAL has risen to meet these challenges by investing in a new, state-of-the-art emissions testing laboratory, housed within a climate chamber. This paper presents BOSMAL’s new M1/N1 vehicular emissions and fuel consumption laboratory in a climatic chamber for the testing of vehicles in accordance with the Euro 5 & 6 and US Environmental Protection Agency (EPA) & California Air Resources Board (CARB) standards. The specifications, capabilities and design features of the sampling and analysis and climate simulation systems are presented and discussed in relation to the increasing drive for cleaner light duty road vehicles. A recently-installed particle number counting system is described in the context of European Union legislation on the emission of particle matter from CI and SI vehicles. The laboratory permits BOSMAL’s engineers to compete in the international automotive arena in the development and construction of new, more ecologically friendly and increasingly fuel efficient vehicles.

Emissions Testing

Legislation regarding the reduction of harmful exhaust emissions, greenhouse gases and fuel consumption is one of the strongest drivers of development in automobile design. Strict legislation requires changes to engine calibration and hardware, but also to test facilities and emissions analysis systems; indeed, emissions standards in the European Union (EU), USA and Japan determine not only maximum permissible emissions factors, but also emissions testing methods and laboratory design. This paper is a continuation of [1], and presents the most recent additions to BOSMAL’s emissions testing laboratory – a recently-installed analyzer bench for modal raw exhaust measurement at both pre- and post-catalytic converter sampling locations, as well as EGR ratio calculation, are described in the context of its sophisticated emissions measurement facilities and the increasingly complex testing demands of vehicle and aftertreatment system manufacturers.
