Abstract ▼ AI-Helper

Automobile industry has been developed rapidly as a key manufacturing industry in Korea. Meanwhile, air pollution is getting worse noticeably than ever. In the diesel emission, PM (Particulate Matter) and NOx (Nitrogen Oxides) have been exhausted with a great amount and the corresponding emission regulations are getting stringent. In order to develop low emission engines, it is necessary to research on better qualified fuels. Sulfur contained in fuel is transformed to sulfur compound by DOC (Diesel Oxidation Catalyst) and then it causes to the increase of sulfate-laden PM on the surface of catalyst. In this research, ULSD (Ultra Low Sulfur Diesel) is used as a fuel and some experimental results are investigated. ULSD can reduce not only PM but also gas materials because cetane value, flash point, distillation 90%, pour point and viscosity are improved in the process of desulfurization. However, excessively reduced sulfur may cause to decease lubricity of fuel and engine performance in fuel injection system. Therefore, it requires only modest adjusted amount of sulfur can improve engine performance and DOC, as well as decrease of emission.

가설 설정

(1) The effect of engine power and fuel consumption is negligible in ULSD when compared with one of standard fuel.

제안 방법

Engine performance test was conducted by increasing engine speed from 1000 rpm to 2200 rpm at 200 rpm interval and measured fuel consumptions, engine powers and torques and took an arithmetic average for 3 seconds after stabilizing fuel consumptions, engine powers and torques for three minutes at a full engine load.

대상 데이터

Test engine is a heavy-duty diesel engine which is manufactured by a Korean motor company and onboard in city buses and heavy trucks.

성능/효과

(2) PM and CO decreased about 5% and HC decreased about 215%. NOx decreased about 2% and SOF and sulfate in PM tend to decrease.
