Question
Pure biodiesel does not emit what pollutant?
Open in App
Solution
The correct option is B Sulfur Dioxides
Typically, emissions of nitrogen oxides are either slightly reduced or slightly increased depending on the duty cycle of the engine and testing methods used. Increases in NOx can be effectively eliminated with the use of normal mechanical remediation techniques (e.g. catalysts or timing changes). Research also documents the fact that the ozone forming potential of the hydrocarbon emissions of pure biodiesel is nearly 50% less than that of petroleum fuel. Pure biodiesel does not contain sulphur and therefore reduces sulphur dioxide exhaust from diesel engines to virtually zero.
