“…Post injection and alternative fuel studies in compression ignition engines have been previously done by many researchers [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. Numerous diesel post injection studies have been carried out to determine the effects of the post injection on soot emissions [20][21][22][23][24][25].…”

“…Furthermore, the regulations for PM and NOx emissions from diesel have strengthened and their emissions are an important environmental issue [6]. Therefore, many researchers have studied ways to reduce exhaust emissions such as PM and NOx by the use of diesel particulate filters (DPF), selective catalytic reduction (SCR) [7,8], and alternative fuels which can be used without requiring modification of the diesel engine [9][10][11][12]. Biodiesel fuels can be produced from various vegetable oils, waste cooking oils, and animal fats.…”

Abstract:In this study, we investigated the effects of canola oil biodiesel (BD) to improve combustion and exhaust emissions in a common rail direct injection (DI) diesel engine using BD fuel blended with diesel. Experiments were conducted with BD blend amounts of 10%, 20%, and 30% on a volume basis under various engine speeds. As the BD blend ratio increased, the combustion pressure and indicated mean effective pressure (IMEP) decreased slightly at the low engine speed of 1500 rpm, while they increased at the middle engine speed of 2500 rpm. The brake specific fuel consumption (BSFC) increased at all engine speeds while the carbon monoxide (CO) and particulate matter (PM) emissions were considerably reduced. On the other hand, the nitrogen oxide (NOx) emissions only increased slightly. When increasing the BD blend ratio at an engine speed of 2000 rpm with exhaust gas recirculation (EGR) rates of 0%, 10%, 20%, and 30%, the combustion pressure and IMEP tended to decrease. The CO and PM emissions decreased in proportion to the BD blend ratio. Also, the NOx emissions decreased considerably as the EGR rate increased whereas the BD blend ratio only slightly influenced the NOx emissions. OPEN ACCESSEnergies 2014, 7 8133

“…In similar fashion, the smoke emissions reduced by about 40-83% at the same load (75%) with 0-30% EGR compared to that of conventional diesel operation. Furthermore, studies by Kim et al [12], Himabindu et al [13] and Wu et al [14] on HCCI combustion characteristics using premixed charge disclosed significant reductions in both NOx and smoke emissions.…”

For the past one hundred years, lots of easily accessible petroleum fuel has been burned out by humankind in inefficient engines. In this regard, present-day engine researchers face a formidable challenge to achieve the goal of significant improvements in both thermal efficiency and fuel economy. Although the direction to reach this target is critical, homogenous charge compression ignition (HCCI) is just another combustion concept to achieve this target. By the way, this work investigates the combustion phenomena of the HCCI engine by external mixture formation technique. In a nut-shell, an endeavor has been made in this work to prepare homogeneous mixture outside the combustion chamber using a fuel vaporizer system to form a uniform fuel-air mixture. The fundamental research experiments were carried out with vaporized diesel and vaporized e-diesel blends (10% and 20% ethanol substitution by volume), and the results were compared with conventional diesel engine operation. In HCCI mode, the maximum rate of pressure rises and the maximum rate of heat-release significantly reduced with increase of ethanol concentration in diesel. The experimental outcomes exposed that when HCCI engine is operated with e-diesel blend, smooth engine operation is apparent. ª 2015 Faculty of Engineering, Alexandria University.
