“…Hawirko et al developed an on-board emissions measurement system using a Vetronix PXA-1100 5-gas analyzer with a built-in sample handling system, a wideband lambda sensor, a hot-wire Siemens mass air flow meter, and temperature probes for coolant, ambient and inlet temperatures [25], All parameters were logged on a laptop computer at an average of 1.5Hz along with engine and road speed. The analyzer used NDIR for HC, CO and CO 2 , and electro-chemical cells for NO x and O 2 .…”

“…Por su parte la Universidad de Alberta, desarrolló un sistema no intrusivo diseñado para ser instalado en cualquier vehículo. Este sistema se desarrolló con la capacidad de registrar condiciones ambientales, comportamiento del conductor, parámetros operativos del vehículo, consumo y emisiones en los gases de escape (Hawirko & Checkel, 2002). Así mismo, el Imperial College of Science, Technology and Medicine de Londres, desarrolló un PEMS al que llamó VPEMS y en el que se usó la ECU para obtener la información de la actividad del vehículo (Ochieng et al, 2002).…”

Class-8 trucks with GVWR of 80,000 lbs were tested on different driving routes and inuse brake-specific emissions of NO x and CO 2 data were collected using the West Virginia University's Mobile Emissions Measurement System (MEMS). An uncertainty analysis was performed on the MEMS and it was determined the maximum possible error in the measurement of brake-specific emissions of NO x was 8% and CO 2 was 6%. A modal analysis indicated that the cruise mode comprised 70% of the time that the vehicle spent in the Not-to-Exceed (NTE) zone while the acceleration and deceleration modes about 20% and 10% respectively. In order to reduce the uncertainties in emissions measurement, it is proposed that fuel specific NO x , a ratio NO x /CO 2 be used for emissions compliance purposes. The values of the proposed ratio were found to vary from 1.17 to 1.83 depending upon engine model, model year, manufacturer and the driving route.
