Conducted measurements on biodiesel emissions results from an internal combustion engine.
- Conducted measurements on biodiesel emissions from an internal combustion engine (92hp 4-cylinder VW Jetta TDI) at Tecnológico de Monterrey.
- Test of B100 and B20 formulations; virgin soy bean oil and waste vegetable oil (WVO) were used as feedstock.
- Measurements performed according to Mexican norm NOM-047-ECOL-1999 wih two alternative measurement protocols (i.e. based on no-load and on dynamic)
- Considering only "pure" feedstocks (soybean oil or waste vegetable oil with no cocnut admixture) all formulation show a very similar picture.
- with reduction in CO emissions of 70 to 90%
- reductions in total hydrocarbons of 20%
- slight decrease in NOx emissions (contrary to the slight increase generally reported in literature)
