“…In case of diesel engines, these penalties include higher specific fuel consumption and particulate matter emissions. Effectively, a tradeoff between NO x and soot is observed with the use of EGR [22][23][24][25][26][27]. The reduction in flame temperature reduces the rate of soot oxidation/re-burning.…”

“…released heat. Less heat will then be released during combustion to oxidize the carbon molecules [18]. With increasing CO 2 concentration, such dilution effect is greater than the chemical effect resulted from the dissociation reaction of CO 2 to nullify its soot suppression.…”

This study investigated the inluence of a four-cylinder naturally aspirated directinjection diesel engine fueled with diesel-biodiesel-ethanol blended D"E) fuels tested at a steady state speed of rev/min under diferent engine loads, ethanol volume and intake carbon dioxide CO ) dilution ratios on engine performance, combustion characteristics, regulated gaseous emissions, and soot agglomerates. Overall, the experimental results indicate that D"E blends can in general improve brake thermal eiciency "TE) and reduce nitrogen oxides NO x ), carbon monoxide CO), CO , volatile organic fractions, particulate mass PM), and particulate number PN) concentrations, while brake-speciic fuel consumption "SFC) and hydrocarbon HC) might increase slightly. Compared with ultra-low-sulfur diesel, D"E blends can maintain a good tradeof relationship among PM-PN-NO x . Compared with biodiesel, the blended fuels perform beter in suppressing brake-speciic particle number emissions "SPN), leading to a reduction of ultraine and nanoparticle numbers. The combined efect of D"E blends with intake CO dilution has marginal efects on "SFC and "TE, signiicantly reducing NO x emission while slightly increasing particulate emissions. On particulate characteristics, D"E blends produce soots with curved, tortuous, and disorganized nanostructures with low soot burnout temperature and strong oxidation rate favoring PM-PN reduction.Keywords: diesel-biodiesel-ethanol, combustion characteristics, gaseous emissions, particle emissions, particle morphology © 2016 The Author(s).

Food, energy, and environment trilemma 19Of the alternative biofuels, the most widely investigated include biodiesel and ethanol [ ]. 20These two fuels have clear emission advantages over diesel. However, some studies have raised 21the concern of "food versus fuel" arising from plant-based biodiesel and ethanol, which might 22 be the main hurdle for commercialization [ ]. In fact, the economic consequences of these 23 biofuel expansions are mixed and there are still some issues that will inluence the actual 24 impacts on food costs that have not been accounted for. To counter the "food, energy, and 25 environment trilemma", the development of these biofuels from nonfood sources i.e., 26biodiesel from waste cooking oil, ethanol from cellulosic nonfood crops, etc.) can show great 27 promise in reducing food commodities being utilized for biofuel production [ ]. 28. .

The usage of EGR adopted diesel engine increasing day by day world wide to reduce the NOx emissions. The EGR adopted engines can reduce NOx Considerably but it adversely improves the emissions of UHC nearly 40 to 50 %. We can avoid this effect by Reutilizat ion of UHC. In this paper the experimental investigation has been carried out on EGR adopted direct injection co mpression ignition engine with insertion of unburned hydro carbon rich exhaust. The results were presented and compared with all EGR levels. The result were evidenced that can reduce 20 to 25 % of UHC by this method.
