“…The value of BSEC increases with the alteration of injection timing and keeps on reducing while the engine is operated with increasing loads. The quality of fuel plays a vital role with the combination of cylinder pressure in deciding the fuel [7,18,19]. The BSEC varies from 18.56 MJ/kWh to 11.57 MJ/kWh for standard injection timing at no load to full load operations, respectively.…”

The disposal of waste plastic solids are becoming more than a crisis with respect to environmental safety. Proper disposal system may either be very expensive or leads to side effect. Hence researchers are looking for suitable methods to reuse them. Oils as substitute for petroleum products in internal combustion engines are gaining focus in India, because of its potential to generate large scale employment and relatively low environmental poverty. The present work aims at utilizing this waste plastic oil in a low heat rejection retarded timing engine whose combustion chamber surface is coated with partially stabilized zirconia (PSZ) ceramic. The influence of fuel injection timing was studied to completely understand the waste plastic oil performance in low heat rejection engine. The results revealed great improvement in performance, and emission characteristics. As a compensation, NOx formation was slightly increased. Overall performance of the low heat rejection engine with waste plastic oil fuel was better with 14⁰ bTDC retarded injection time.

“…Several studies has been performed by many researchers to eliminate these disadvantages and various methods have been proposed like EGR (exhaust gas recirculation) [16][17][18], changing valve lift [19,20], changing inlet air temperature [21,22], changing compression ratio [23], using different fuels [24][25][26]. HCCI engines have also fuel flexibility such as diesel, gasoline, natural gas and some alcohols [27][28][29]. Various alcohols including ethanol [30,31], methanol [32][33], diethyl ether [34-35] and others [36][37] have been used and blended with primary reference fuels, isopropanol and n-heptane in HCCI engines.…”

Published by Editorial Board Members of IJAET © This article is distributed by Turk Journal Park System under the CC 4.0 terms and conditions.Homegeneous charge compression ignition (HCCI) combustion can achieve very low NOx and soot emissions but knocking and misfiring restrict the operating range of this kind of engines. In this work, n-butanol which has low reactivity and high volatility blended with n-heptane that choosen as reference fuel in this study with various rates (25 vol% and 50 vol%). The experiments performed at various engine speeds (800-1800) and lambda (λ=1.6-2.95) at full load and 60 o C inlet air temperature. the parameters such as in-cylinder pressure, heat release rate, CA10, ringing intensity, thermal efficiency, brake torque, power output, specific fuel consumption, and HC and CO emissions were determined. The results showed that both in-cylinder pressure and heat release rate decreased with increasing lambda. Increasing amount of n-butanol in the charge mixture resulted a decrease both in-cylinder pressure and heat release rate. nbutanol also provided retarded combustion phasing and increased CA10. Ringing intensity decreased with increasing both lambda and n-butanol content in the mixture. Thermal efficiency increased with n-butanol. HC and CO emissions increased with increasing lambda. HC and CO emissions increased with increasing amount of n-butanol in the charge mixture. Operating range of HCCI engine was expanded with n-butanol in both knocking and misfiring zones.

In this study, the influences of injection timing and exhaust gas re-circulation on combustion and emissions characteristics of biodiesel/2-methylfuran blends are investigated on a modified water-cooled 4-cylinder four-stroke direct injection compression ignition engine. The experimental conditions are, respectively, to adjust injection timing and exhaust gas re-circulation ratio at 0.38 MPa break mean effective pressure with the engine speed at 1800 rpm constantly. With injection timing in advance, the peak cylinder pressure rose while maximum heat release rate first decreased and next slightly raised. Ignition delay and brake specific fuel consumption reduced first and then raised while combustion duration and break thermal efficiency had the opposite trend. The NOx emissions increased, and HC emissions first reduced significantly and then slightly increased, while 1,3-butadiene and acetaldehyde emissions presented a reduction tendency. As exhaust gas re-circulation ratio increased gradually, ignition delay as well as combustion duration was prolonged. brake specific fuel consumption increased and break thermal efficiency declined. HC, CO, 1,3-butadiene, and acetaldehyde emissions raised while NOx emissions reduced significantly. Biodiesel could behave well in a Diesel engine and thus a feasible alternative fuel for diesel. Moreover, methylfuran addition into biodiesel could raise break thermal efficiency and the break thermal efficiency of BM20 is higher than BM10. However, both BM10 and BM20 appeared a combustion deterioration when injection timing at 2.5 °CA before top head center.
