The non-regulated emissions from a turbo-charged diesel engine under steady-state operation with hydro-processed renewable diesel (HRD)

摘要

An application of hydro-processed renewable diesel (HRD) intended to reduce non-regulated emissions, including formaldehyde, acetaldehyde, benzene, toluene, and xylene (BTX), is proposed in this study, in association with the emissions from a turbo-charged common-rail direct-injection diesel engine under steady-state operation. Three types of fuel, pure petro-diesel, 20% HRD blended fuel (H20), and 20% biodiesel blended fuel (B20) were tested under various engine loads and engine speeds. According to the emissions analysis, in which the samples were collected and analyzed through the solid phase micro-extraction (SPME) technique adapted with a derivation method, a 20% addition of HRD reduced the emissions of formaldehyde, acetaldehyde, benzene, toluene, and xylene, as compared to D100 and B20.
