Development of Premixed Low-Temperature Diesel Combustion in a HSDI Diesel Engine

Suitability analysis of advanced diesel combustion concepts for emissions and noise control

“…For extremely advanced SOE, soot emissions are close to zero, but these operation points do not have any practical interest because of the problems previously commented, which are critical here. The SOE ranges suitable for PCCI combustion obtained in the tests agree with previous results found in the literature [38,39]. However, despite the interesting pollutant emissions reduction attained, the engine performance at these operating conditions is not acceptable when compared with that obtained with conventional combustion.…”

Effect of pilot injection on engine noise in a single cylinder compression ignition engine

“…Ignition delay is defined as the time between the start of injection and the start of detectable heat release and in this paper the start of detectable heat release is defined as the point that accumulated heat release rate reachs to the 10% of total accumulated heat release rate. As a result, pilot injection can prevent drastic increases in pressure, lower maximum pressure rise rate (MPRR) (Yun et al, 2008), and diminish combustion noise. In addition, NOx also decreases but particulate matter increases.…”

Recent development of biodiesel combustion strategies and modelling for compression ignition engines

“…Yun at al. [170] studied the effect of increasing swirl ration (1.0 to 4.0) on emission from premixed low temperature diesel combustion. They found a significant reduction of soot emission for advanced injection timing.…”
