“…Sustainable renewable sources (biofuels namely alcohol and biodiesel) paying significant attention in recent times alternate to conventional diesel fuels [5,8]. In particular, biodiesel performance in diesel engines are studied by many authors [9][10][11][12]. The information corresponding to various feedstocks and techniques employed for oil extraction, necessary for biodiesel production is mentioned in the literature [9].…”

“…Further, their advantages towards practical utility in diesel engines were analysed [10]. Engine performance and emission characteristics of honge and cotton seeds biodiesel were tested at different load conditions with homogeneous charge compression ignition (HCCI) type engine [11]. The performances of compressed natural gas with air and diesel/hone oil with methyl ester were tested on both HCCI and dual fuel type engines [12].…”

The use of abundantly available Garcinia gummi-gutta seeds grown at forest lands and ethanol a by-product of sugar industries has led to resource conservation and their use as alternate fuel to diesel engines for pollution reduction. Garcinia gummi-gutta (GGG) oil-based methyl esters blended with 20% ethanol and diesel fuel composed of six fuel samples (D100, B20E20, B30E20, B40E20, B100E20 and B100) are tested at different engine loads (0%, 20%, 40%, 80% and 100%) for their practical usefulness in diesel engine. Six fuel samples are tested for fuel properties. Biodiesel–diesel–ethanol blends showed approximately closer fuel properties to standard diesel fuel. Tests are carried out experimentally to know their performance and emission characteristics of six test samples fuelled in diesel engine varied subjected to different loads. Brake specific fuel consumption for all biodiesel blends is slightly higher for diesel fuel and its proportion decreases with increase in engine load. At full load engine condition, the brake thermal efficiency (BTE) for diesel fuel is 26.25%, and for biodiesel blends vary in the ranges of 22.5 to 25.2%. Compared to diesel fuel there is a reduction in 32.56% of carbon monoxide (CO) emission and 35.71% of hydrocarbon (HC) emission for biodiesel fuel (B100E20). For all biodiesel blended fuels tested at all engine loads, the oxides of nitrogen (NOx) emissions are marginally higher than diesel fuel. At full load engine condition, B100E20 (100% diesel and 20% ethanol) reduces CO emissions by 6.45%, HC emissions by 6.64%, and increases BTE by 0.8%, compared to neat biodiesel (B100). GGG based biodiesel blended with ethanol resulted with better fuel properties, performance and emission characteristics to that of diesel fuel. Garcinia gummi-gutta seed yields 45% of oil with a high conversion ratio to biodiesel of 1:0.96, which help the industry for biodiesel production in large scale at reduced cost.

“…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. Butanol is renewable fuel that have various advantages for internal combustion 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.

“…It consists of preparing a highly homogenous air/fuel mixture that will result in a homogenous and efficient in-cylinder combustion. Thus, a complete and controlled combustion would mean better performance, lower emissions and above all no soot is produced [11].…”

“…An engine a fixed with low compression ratio provides performance with low maximal cylinder pressure which in turn means low frictional losses, costs and weight of the engine but limits the maximum achievable torque. An engine like this requires a glow plug which gives it a cold start ability resulting in a more stable idle operation and less smoke [11][12][13][14]. Therefore, the new technology of variable compression ratio (VCR) offers more flexibility in terms of controlling power and emissions at different operating load conditions.…”

With emission legislation becoming ever more stringent, declining fossil resources and an increase in greenhouse effect caused by CO 2 emissions, manufacturers are exploring new ways to match the emissions regulations without compromising on the performance of the engine. This study included development of zero-dimensional model of a 2.0 L turbocharged diesel engine and then study the effects of changing its compression ratio in the numerical model. This paper gave a framework in determining the effect of compression ratios in different operational conditions of the engine. Implementation of variable compression ratio technology on a numerical model proved to be very cost-effective, time saving and validated the fact that numerical models can be used to study different parameters of the engines during the development stage. The main effect of an increase in compression ratio, was found to be as expected, a decrease in brake specific fuel consumption and an increase in thermal efficiency with a greater impact at low rpm-low load regions. Assuming, that the variable compression ratio technology can be utilized in the engine, this work found the best combination of compression ratios around the engine map, giving a best fit of trade-offs between the emissions and performance of the engine. This study also validates the fact that variable compression ratio technology, if implemented in the engine could not only reduce emissions of the engine but can be given as an option to the end-user to switch to more economic fuel consumption values during idling or cruising at long distant journeys.
