    When diesel is used as an engine fuel, it is inevitable that you will produce Products of Incomplete Combustion (PICs). Hence, we never just produce carbon dioxide (CO2) and water (H2O) alone, but rather a myriad of hydrocarbons including aromatics (e.g. benzene, toluene) aldehydes and poly-aromatic hydrocarbons (PAHs) in a semi-volatile phase or bound with carbonaceous particulate, and ...
