Low Heat Rejection Engine

The usage of alternate fuels has been a priority ever since the depletion of the conventional fuels. During the recent times the concept of using biodiesel as fuel has been predominant due to its ability to be used in the same engine as conventional fuels. The source of biodiesels are mainly non edible oils such as Jatropha and Pongamia. This paper reviews the properties of the alternate fuels when used in the compression-ignition engine. These alternate fuels used are vegetable oils and alcohols. The review compares the key properties of diesel to the alternate fuels used. The properties such as such as brake thermal efficiency, volumetric efficiency, exhaust gas temperature and smoke levels are compared with the values obtained from the usage of conventional diesel fuel in a low heat rejection engine (L.H.R) engine. apart from the properties there is also a need for the check of pollutants emitted during the processes, oxides of nitrogen from diesel fuel and aldehydes from the alternate fuels.

In this study, engine performance on thermal factors for different biodiesels has been studied and compared with diesel fuel. Biodiesels were produced from Pongamia pinnata (PP), Calophyllum inophyllum (CI), waste cooking oil (WCO), and acid oil. Depending on their free fatty acid content, they were subjected to the transesterification process to produce biodiesel. The main characterizations of density, calorific range, cloud, pour, flash and fire point followed by the viscosity of obtained biodiesels were conducted and compared with mineral diesel. The characterization results presented benefits near to standard diesel fuel. Then the proposed diesel engine was analyzed using four blends of higher concentrations of B50, B65, B80, and B100 to better substitute fuel for mineral diesel. For each blend, different biodiesels were compared, and the relative best performance of the biodiesel is concluded. This diesel engine was tested in terms of BSFC (brake-specific fuel consumption), BTE (brake thermal efficiency), and EGT (exhaust gas temperature) calculated with the obtained results. The B50 blend of acid oil provided the highest BTE compared to other biodiesels at all loads while B50 blend of WCO provided the lowest BSFC compared to other biodiesels, and B50 blends of all biodiesels provided a minimum % of the increase in EGT compared to diesel.

This paper presents the performance of biodiesel blends in a single-cylinder water-cooled diesel engine. All experiments were carried out at constant speed 1500 rpm and the biodiesel blends were varied from B10 to B100. The engine was equipped with variable compressions ratio (VCR) mechanism. For 100% Jatropha biodiesel, the maximum fuel consumption was 15% higher than that of diesel fuel. The brake thermal efficiency for biodiesel and its blends was found to be slightly higher than that of diesel at various load conditions. The increase in specific fuel consumption ranged from 2.75% to 15% for B10 to B100 fuels. The exhaust gas temperature increased with increased biodiesel blend. The highest exhaust gas temperature observed was 430°C with biodiesel for load conditions 1.5 kW, 2.5 kW, and 3.5 kW, where as for diesel the maximum exhaust gas temperature was 440°C. The CO2emission from the biodiesel fuelled engine was higher by 25% than diesel fuel at full load. The CO emissions were lower with Jatropha by 15%, 13%, and 13% at 1.5 kW, 2.5 kW, and 3.5 kW load conditions, respectively. TheNOxemissions were higher by 16%, 19%, and 20% at 1.5 kW, 2.5 kW, and 3.5 kW than that of the diesel, respectively.

The aim of this experimental work is to study the effect of nanoparticles added to diesel fuel on engine performance characteristic. Nano fuels are prepared by adding Al2O3 or TiO2, both with particle size less than 45nm of diesel fuel. Four doses of each type namely (25, 50, 100 and 150) ppm are prepared. These nanoparticles are blended with diesel fuel in varying volume fraction by the means of an electric mixer and an ultrasonicator. The Nano fuels are (DF+Al2O3) and (DF+TiO2). Physicochemical properties of nano fuels are measured and compared with these of neat diesel. The study shows that the addition of nanoparticles to diesel fuel improves its physical properties such as cetane number, thermal conductivity and viscosity. The influence of nanoparticles addition is very clear on the engine performance. The results show that the performance parameters are improved for example, brake thermal efficiency is increased from 19.4% for diesel to 21% and 25% for DF+Al2O3 and DF+TiO2 respectively, the brake specific fuel consumption (BSFC) is decreased by 8% and 20% for DF+Al2O3 and DF+TiO2 respectively, the brake specific energy consumption (BSFC) is decreased by 8% and 20% for DF+Al2O3 and DF+TiO2 respectively at 25ppm and 75% load. The exhaust gas temperature is 382°C for pure diesel while it is 417°C for DF+Al2O3 and 353°C for DF+TiO2. The peak pressure for pure diesel is 62 bar and it increases with DF+Al2O3 to 66.2 bar as for DF+TiO2 the peak pressure decreases to 57.2 bar at full load and 150ppm.

The effect of iso‐butanol addition to diesel fuel on engine performance parameters has been experimentally investigated. The used engine was a single cylinder four stroke CI engine Type Lister 1–8. The tests were performed at engine speed that ranges from 375 to 625 with an increment of 42 rpm at different loads and with 10, 20, 30 and 40% v/v iso‐butanol‐diesel fuel blends. The overall engine performance parameters measured included air‐fuel ratio (AFR), exhaust gas temperature, brake power (Bp ), brake specific fuel consumption (bsfc) and brake thermal efficiency (η th ). The experimental results show that AFR, exhaust gas temperature, (Bp ) and (ηbth ) decreased and bsfc increased with iso‐butanol addition compared to net diesel fuel. Also, the obtained results indicate that the engine performance parameters when using up to 30% iso‐butanol in fuel blends are better than that of 40%.

Abstract Persistent increase in demand and depletion of world fossil fuel reserve has necessitated the lookout for alternative fuels. One such indigenous biodiesel with significant potential is the biodiesel extracted from Roselle whose technical feasibility to operate with compression ignition engine is investigated in this study. Experimental and empirical methodologies had been employed to characterise the fuel blends while operating at engine loads of 25%, 50%, 75% and 100%, and with fuel injection timings of 19°, 21°, 23°, 25° and 27° bTDC. Results showed that for 20% blend, with advanced injection timing from 19° bTDC to 27° bTDC at full load, brake specific fuel consumption and exhaust gas temperature for 20% blend was higher by 15.84% and 4.60%, while decrease in brake thermal efficiency by 4.4%. Also, 18.89% reduction in smoke, 5.26% increase in CO2 and 12.94% increase in NOx were observed. In addition, an empirical model was developed for full range characterisation. The artificial neural network model thus developed to characterise all the 10 variables was able to predict satisfactorily with r-squared value of 0.9980 ± 0.0011. Further, high correlation amongst certain variables indicated to plausible empirically reduced models.

Synthesis gas (Syngas), a mixture of hydrogen and carbon monoxide, can be manufactured from natural gas, coal, petroleum, biomass, and even from organic wastes. It can substitute fossil diesel as an alternative gaseous fuel in compression ignition engines under dual fuel operation route. Experiments were conducted in a single cylinder, constant speed and direct injection diesel engine fuelled with syngas-diesel in dual fuel mode. The engine is designed to develop a power output of 5.2 kW at its rated speed of 1500 rpm under variable loads with inducted syngas fuel having H2 to CO ratio of 1:1 by volume. Diesel fuel as a pilot was injected into the engine in the conventional manner. The diesel engine was run at varying loads of 20, 40, 60, 80 and 100%. The performance of dual fuel engine is assessed by parameters such as thermal efficiency, exhaust gas temperature, diesel replacement rate, gas flow rate, peak cylinder pressure, exhaust O2 and emissions like NOx, CO and HC. Dual fuel operation showed a decrease in brake thermal efficiency from 16.1% to a maximum of 20.92% at 80% load. The maximum diesel substitution by syngas was found 58.77% at minimum exhaust O2 availability condition of 80% engine load. The NOx level was reduced from 144 ppm to 103 ppm for syngas-diesel mode at the best efficiency point. Due to poor combustion efficiency of dual fuel operation, there were increases in CO and HC emissions throughout the range of engine test loads. The decrease in peak pressure causes the exhaust gas temperature to rise at all loads of dual fuel operation. The present investigation provides some useful indications of using syngas fuel in a diesel engine under dual fuel operation.
