Abstract
<div class="section abstract"><div class="htmlview paragraph">This study numerically investigates the toxicity potential of polycyclic aromatic hydrocarbon (PAHs) emitted from conventional diesel and hydrogen–diesel dual-fuel combustion engine. The simulations are performed on ANSYS Forte using a detailed chemical reaction mechanism of diesel surrogate (66.8% n − decane/33.2% alpha − methylnaphthalene). The used reaction mechanism consists of 189 species and 1392 reactions. The study numerically predicts the concentration of eight toxic PAHs (naphthalene, phenanthrene, acenaphthene, pyrene, chrysene, benzo[a]pyrene, benzo perylene, and benzo [g, h, i] perylene) emission for which carcinogenicity and mutagenicity potential is determined. Results demonstrate that hydrogen-diesel dual-fuel engine has lower carcinogenicity and mutagenicity potential than the conventional diesel engine.</div></div>
