Advanced ceramic coating technologies are commonly used as metal coatings for internal combustion engine components and aerospace application. The thermal barrier coatings are being applied to the engine components to increasing life and improve the performance of the engine. This experimental study is focused on advanced ceramic material of Zirconia stabilized with the yttrium oxide (Zirconia 80% wt and Yttia 20 % by weight) applied on the piston crown for analyzing the performance and emission characteristics of the diesel engine. By using ceramics coated piston crown, the brake thermal efficiency and specific fuel consumption were improved as compared to that of the piston without coating. Exhaust emission level of CO, UHC and NOx are also considerably reduced using advanced ceramic metal coating techniques.

Abstract: There is growing interest to study the effect of blending various oxygenated additives with diesel or biodiesel fuel on engine performance and emission characteristics. This study aims to analyze the performance and exhaust emission of a four-stroke, four-cylinder diesel engine fueled with biodiesel-ethanol-diesel. Biodiesel was first produced from crude Jatropha oil, and then it was blended with ethanol and fossil diesel in different blend ratios (B10E10D80, B12.5E12.5D75, B15E15D70, B20E20D60 and B25E25D50). The engine performance and emission characteristics were studied at engine speeds ranging from 1200 to 2000 rpm. The results show that the brake specific fuel consumption increases while the brake power decreases as the percentage of biodiesel and ethanol increases in the blend. The exhaust emission analysis shows a reduction in CO2 emission and increase in NOx emission when the biodiesel -to- ethanol ratio increases in the blends, when compared with diesel as a reference fuel.

Biodiesel, a biodegradable, highly oxygenated and renewable energy resource, is produced by esterification of vegetable oils. This work focuses on using electrolytic separation and emulsification to produce purer biodiesel having high cetane index of 61.4. Vegetable oil mixture is used as feedstock. Maximum production yield is 84%. The decrease in engine peak torque was minimum for B5 at 1.94% while maximum decrease was for B20. B5 show a slight increase in power while B20 and B50 show significant drop. For all test speeds, B50 shows higher efficiency than all test fuels however the BSFC was significantly higher than diesel until 88.8% of the maximum engine speed. The maximum increase in brake thermal efficiency for B5 is found to be 2.09% which is 7.9% more than diesel at 2000 rpm. A significant increase of maximum 3.719% in brake specific fuel consumption (BSFC) is observed. Maximum reduction in CO emissions is 53.3% for B50 at 2250 rpm accompanied with a maximum average drop in HCs of 74.4%. The variation in the NOx is insignificant. B5 is found to be the most effective blend for both maintaining the engine performance and improving the engine emissions.

Alcoholic fuels have some significant advantages over other alternative fuels. The alcoholic fuels can be implemented in existing engines and they have the capability of reducing greenhouse gas emissions. In this experimental analysis, the performance and emission characteristics of Spark Ignition (SI) engine using isopropyl alcohol as additive to petrol and kerosene. This experimental evaluation deals with strategically analysis of SI engine by using two different combinations of fuels. Isopropanol has been doped with unleaded gasoline and kerosene in the volumetric ratio of 10%, 20%, 30% and 40% (IPA10, IPA20, IPA30 and IPA40). It has been observed that considerable reduction in carbon monoxide and hydrocarbon emission and increased Brake Thermal Efficiency (BTE) while the NOx emission was increased. Electrical loads have been applied in the engine with bulbs of different wattages of 15 Watts and 60 Watts. In each test one fuel will be supplied and the amount of electrical load that the engine may bear will be analyzed. The performance characteristics of the engine and efficiency have been analyzed. From the result obtained it has been observed that isopropyl additive mixture will give more efficiency and more economical.

The Core

The core object of this study is to examine the suitability of linseeds for biodiesel production. The performance of an engine at different proportions of linseed blends with petro-diesel and the amount of emissions rate were investigated. Initially, linseed biodiesel was produced through transesterification process, and then it was mixed with petro-diesel fuel (D100) blends at volumetric ratios of 10% (LB10), 20% (LB20), and 30% (LB30). The properties of linseed biodiesel and its blends were investigated and compared with petro-diesel properties with reference to ASTM standards. It has been observed that the fuel properties of produced biodiesel are within ASTM permissible limits. The specific fuel consumption (SFC) of LB10 blend has been found lesser compared to LB20 and LB30. SFC of D100 is slightly less than that of all the blends. The brake thermal efficiency (BTE) of LB30 is greater than that of pure diesel D100 at maximum load and greater than that of LB10 and LB20. The heat dissipation rate in all linseed blends is found to have been less than that of D100. Carbon monoxide, carbon dioxide and NOx emissions of linseed blends are mostly lower in comparison with D100’s. Among all blends, LB10 was found more suitable alternative fuel for diesel engines and can be blended with petro diesel without engine modifications. It can be concluded that cultivation and production of linseed in Pakistan is very promising, therefore, it is recommended that proper exploitation and use of linseed for energy production may be encouraged through pertinent agencies of Pakistan.

Leaf Oil

Turmeric leaves are waste products after removing turmeric rhizome. In the present work, the oil was extracted from the leaves of curcuma longa by hydro distillation method. The extracted oil was studied for preliminary physicochemical and phytochemical tests. The phytochemical evaluation of the turmeric leaf oil indicates the presence of terpenes which was used to run two stroke and four stroke engines. Engine emits less harmful product with turmeric oil as compared to petrol. Hence, it has been concluded that the turmeric leaf oil can be used as an alternative biofuel for petrol. Theoretically, turmeric leaf oil properties are similar to that of petrol. By performing practical experiments on this oil using different types of piston head shapes and varying parameters, we came to know that this will fulfil all capabilities as a biofuel in IC engines. In the second part, the characteristics fuel properties of turmeric leaf oil and their blends with petrol in the proportion of 40:60 (B40) have been studied. In the third part, engine tests have been conducted on turmeric leaf oil blends with petrol oil and brake thermal efficiency, engine gas temperature and air fuel ratio were evaluated. The next part consists of exhaust emission tests such as CO and HC emission measurement with a five gas analyser.

The use of liquefied petroleum gas (LPG) is experimented with to improve the performance of a dual fuel compression ignition (CI) engine running on Karanja oil methyl ester (KOME) blends. Diesel is used as a reference fuel for the dual fuel engine results. During the experimentation, the engine performance is measured in terms of brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC), and exhaust emission is measured in terms of carbon monoxide (CO), hydrocarbon (HC), and oxides of nitrogen (). Dual fuel engine with LPG showed a reduction in and smoke emission; however, it suffers from high HC and CO emission, particularly, at lower loads due to poor ignition. Comparison of performance and emissions is done for diesel and blends of KOME. Results showed that using KOME blends (10% and 20%) has improved the CI engine performance with a reduction in HC and CO emissions.
