As oil prices rise, cases of using marine diesel by mixing it with automobile diesel or directly using marine diesel are increasing in some coastal areas. Unlike vehicle diesel, marine diesel contains a significant amount of sulfur, which poisons the catalyst of the reduction device installed to reduce emission, increasing emission and causing malfunction. In this study, the effect of high sulfur diesel on the emission and particle number of old diesel vehicles and the latest regulated vehicles was studied. Compared to general diesel, NMHC emission gas concentration increased by 248.3%, CO 195.2%, NOx 33.0%, and PM 33.2% in old diesel vehicles to which high sulfur diesel was applied. In the case of emissions of the latest regulated vehicles, the level of gaseous emission increase was lower than that of old diesel vehicles, but in the case of PM and PN, they increased significantly by 335.5% and 511.4%, respectively.
As such, it was confirmed that sulfur oxides(SOx) generated during combustion in the engine poisoned the catalyst in the reduction device and deteriorated the performance, thereby increasing the emission. In addition, when high sulfur diesel is used for a long period of time, it is judged that it will cause failure of expensive emission reduction devices such as DOC, DPF, and SCR, which will greatly affect parts damage and driver safety threats.
