Abstract Exhaust emissions and their effects on the environment human health, such as mutagenicity of particulate matter (PM) ozone‐forming potential, must be considered when using an alternative fuel. In present work, a test engine two agricultural tractors ran rapeseed oil methyl ester (biodiesel) or conventional diesel fuel well blends thereof. The objective was to detect any disproportionately positive negative depending blend levels, because biodiesel can blended in every ratio. Generally, regulated compounds changed linearly with level. known varied accordingly. Overall, no optimal found. Increasing content caused linear increase benzene five‐mode test, effect that may explained from previous studies precombustion chemistry. engine, it found PM significantly reduced mutagenic potential compared fuel, although this work masses were reproducibly higher for Ozone precursors increased 10–30% Emissions aldehydes alkenes are mainly responsible effect.
