Measurement Of Gas-phase Acids In Diesel Exhaust




American Geophysical Union, Fall Meeting 2012, abstract id. Gas-phase acids were measured using chemical ionization mass spectrometry (CIMS) as part of the Diesel Engine Emission Research Experiment (DEERE). The CIMS technique, utilizing acetate ion (CH3COO-) as a reagent ion, proved to be a rapid (measurements on the order of seconds) and sensitive (several counts/pptv) method of quantifying the acid emissions. Diluted diesel exhaust measurements were made from a Constant Volume Sampling dilution tunnel using a light duty (1.9L turbocharged Volkswagen Jetta TDI) diesel engine equipped with an OEM diesel oxidation catalyst and exhaust gas recirculation, mounted on an engine dynamometer. Acids measured included isocyanic, nitrous, nitric, propionic and sum of lactic and oxalic, as well as other unidentified compounds. Complimentary measurements of CO, CO2, Total Hydrocarbon (THC), and NOx, were also performed. Several engine modes (different engine rpm and torque outputs) at steady state were examined to determine their effect on acid emissions. Emission rates with respect to NOx and fuel based emission factors were determined.

Volkswagen unveiled the VW Virtus in Brazil last month. The company has developed the small sedan for markets like South America, Central America, and the Caribbean region. According to a report from Al Volante, the VW Virtus could replace the India-made VW Vento in Mexico in Q1 2018. Volkswagen revealed the car in Brazil last month, but there too, sales will commence only in January next year. The VW Virtus is essentially the sedan version of the sixth-gen VW Polo, which went on sale in Brazil just last month. Based on the MQB A0 platform, the VW Virtus measures 4.48 metres in length and has a 2.65-metre wheelbase, which is the same as the VW Jetta鈥檚 wheelbase. The Virtus鈥?body is 1,751 mm wide and 1,468 mm tall. Its width is the same as that of the all-new Polo, but its height is 4 mm more. The B-segment sedan has a boot space of 521 litres. Volkswagen has confirmed only one engine for the VW Virtus so far - 1.0-litre TSI. This flex-fuel engine develops up to 128 hp and 200 Nm of torque. A 6-speed automatic transmission sends power to the front wheels. Reports say that buyers will also have the option to go for the 1.6-litre MSI flex-fuel engine that develops up to 117 hp and up to 162 Nm of torque. Volkswagen is expected offer this engine with a 5-speed automatic transmission. Engine and transmission choices will differ as per the market. The VW Virtus鈥?production takes place alongside the sixth-gen VW Polo in Sao Bernardo do Campo, Brazil. This plant will supply to the Mexican market as well.
