✦ Synopsis

15 Environment (life cycle analysis) changes in CO, THC, NO,, CO2 and particulate matter emissions: The research programme was developed in two steps. First one, developed in Bogo~, involved a fleet test with 15 public service buses that normally operate in Bogotgt's Savannah, using a portable emissions sampling technology developed for ERMD (DOES2) and following a representative transient driving cycle. Second step, carried out in ERMD's Heavy-Duty Engine Emissions laboratory in Ottawa, tested a 1995 caterpillar 3406E 324,5 kW (435 HP) diesel truck engine on the same samples of Colombian diesel fuels used in the fleet tests performed in BogotA, baselining the tests with a Canadian commercial low sulfur diesel fuel. The two commercial Colombian diesel fuels used had the following properties: high sulfur diesel (HSD), with 3000 ppm (0.3 wt%) of sulfur and a final boiling point (FBP) of 633 K and the new reformulated diesel fuel, with 1000 ppm (0.1 wt%) of sulfur and FBP of 613 K, which is currently been distributed in Bogota. Fleet test show small reduction on CO, THC and TPM, and small increments on CO~ and NO,, but with not statistically significant results, while engine testing shows an strong reduction of 40.8% in TPM when you use the new reformulated diesel fuel (0.1 wt% of sulfur) instead of high sulfur diesel.
