“…In order to have a lowemission diesel engine, the interaction between engine technologies, fuel quality, and emissions needs to be well understood [3]. It is fairly evident that improvements in engine technology have a greater impact on reducing emissions than fuel modification does [4].…”

The exhaust emissions from heavy-duty diesel engines (HDDEs) contribute to the degradation of ambient air quality; therefore, environmental agencies have created stringent emissions standards. Since the implementation of these standards, overall engine and fuel technology improvements have created a significant reduction in emissions. This study was completed in order to evaluate oxides of nitrogen (NO x ) emissions from fuels with and without cetane-improving additives in recent and early production electronically controlled HDDEs. Five engines spanning the model years from 1991 to 2004 were tested using the Federal Test Procedure (FTP) dynamometer cycle with both petroleum-based diesel and B20 as the neat fuel. It was found that the additives had the most impact on reducing emissions at low engine powers, but the engine power range with an NO x benefit varied between engines. The cetane improvers were found only to reduce NO x below a cylinder gas density of 35 kg/m 3 at top dead centre. The lower compression ratio of the 1992 DDC S60 engines reduced the cylinder gas density and provided a larger optimal operating range for the cetane improvers. The cetane improvers reduced NO x at low engine powers and cylinder gas density for the B20 fuel but were less effective than for the neat petroleum fuels.

The effect of diesel fuel sulphur content and cetane number on regulated emissions was investigated in a Euro III diesel passenger car. Experimental results indicated that fuel sulphur level had a significant impact on all regulated emission, especially on PM. Testing fuels of different ignition qualities showed that HC and CO emissions of high cetane number fuels were significantly lower than emissions of a low cetane number fuel. We also observed a little decrease in NOx emissions with an increase in the cetane number.

“…For higher CN fuels a small decrease in NO x emissions can usually be observed. For CN ranging from 40 to 55 around 5% reduction in NO x formation per 10 CN increments was found in a fuel property study [51]. Results from a single cylinder HCCI engine showed the same trend in NO x reduction for fuels with higher CN, presumably "due to lower intake air temperatures required for higher cetane fuels, which results in lower peak combustion temperatures" and an increase in CO emissions [52].…”

Concentration and Size Distributions of Nanoparticle Emissions during Low Temperature Combustion using Fuels for Advanced Combustion Engines (FACE) Peter Bonsack Due to tightening emission legislations, both within the US and Europe, including concerns regarding greenhouse gases, next-generation combustion strategies for internal combustion (IC) diesel engines that simultaneously reduce exhaust emissions while improving thermal efficiency have drawn increasing attention during recent years. In-cylinder combustion temperature plays a critical role in the formation of pollutants as well as in thermal efficiency of the propulsion system. One way to minimize both soot and NO x emissions, is to limit the incylinder temperature during the combustion process by means of high levels of dilution via exhaust gas recirculation (EGR) combined with flexible fuel injection strategies. However, fuel chemistry plays a significant role in the ignition delay; hence, influencing the overall combustion characteristics and the resulting emissions.
