Abstract

Emissions of CO, CO2, and oxygen, exhaust opacity, and engine performance were measured on (1) a 1.4L turbo-charged Elsbett powered Volkswagen Transporter, running on cold pressed, filtered-to-25μ, unprocessed rape seed oil, compared with running on mineral fuel oil; and (2) a 2.4L naturally aspirated Toyota Dyna, running on rape methyl ester compared with running on mineral fuel oil. Emissions of CO were found to be generally higher with the mineral fuel oil than with the rape methyl ester used in the Toyota Dyna; however with the Elsbett engined vehicle running on unprocessed rape seed oil the CO emissions were significantly higher than that of the mineral fuel oil. The emissions of CO2 were similar for both vehicles and for both fuels, whereas oxygen emission was found to be greater with the oil seed rape based fuels than with the mineral fuel for both vehicles. Exhaust opacity was found to be significantly greater for the mineral fuel oil than the oil seed rape based fuels; in the case of the Toyota Dyna running on rape methyl ester the exhaust smoke output was about half that of the mineral based fuel.
