Diesel Engine Emission Aftertreatment Device Aging Mechanism and Durability Assessment Methods: A Review
نویسندگان
چکیده
To meet more and stringent emission standards, the combined technologies must be used to purify pollutants of vehicle exhaust. Among them, aftertreatment devices, including DOC, SCR, DPF, so on, are most efficient methods. However, after long-term running, performance devices will inevitably degrade. There several mechanisms that can explain aging phenomena. For catalytic such as DOC thermal poisoning important reasons for their deterioration. As ash clogging is a key problem its stable working. develop test better faster, accelerated methods researched applied. The small-sample method enables catalyst samples at very low cost, but accuracy may not good enough. Although results whole-vehicle bench engine in accord with real using course, they take too much time expensive widely. Burner promising way simulate running catalysts.

Performance and Emission Characteristics of a Diesel Engine with Cottonseed Oil Plus Diesel Oil Blends
aIn the present study a 4-stroke 5hp diesel engine was tested with Diesel oil plus cottonseed oil blends. The blends in different proportions (10 to 50 percent by volume) were tested at constant speed of 1500 rpm. The said engine is operated at different loads and characteristics like Brake power, Brake thermal efficiency, specific fuel consumption etc. Engine performance for blends resulted in...

The main objective of this research is to study the effects of JP-4-biodiesel-diesel fuel blends and operating parameters on the emission characteristics of a CI engine. The experimental tests were performed on a four-cylinder DI diesel engine. The Mixture-RSM method was used to develop mathematical models based on experimental data. The results showed that with the increase of the biodiesel pr...
