Abstract Emission from the DI diesel engine is series setback for environment viewpoint. Intended for that investigates for alternative biofuel is persuaded. The important hitches with the utilization of biofuels and their blends in DI diesel engines are higher emanations and inferior brake-thermal efficiency as associated to sole diesel fuel. In this effort, Cashew nut shell liquid (CNSL) biodiesel, hydrogen and ethanol (BHE) mixtures remained verified in a direct-injection diesel engine with single cylinder to examine the performance and discharge features of the engine. The ethanol remained supplemented 5%, 10% and 15% correspondingly through enhanced CNSL as well as hydrogen functioned twin fuel engine. The experiments done in a direct injection diesel engine with single-cylinder at steadystate conditions above the persistent RPM (1500RPM). Throughout the experiment, emissions of pollutants such as fuel consumption rate (SFC), hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx) and pressure of the fuel were also measured. cylinders. The experimental results show that, compared to diesel fuel, the braking heat of the biodiesel mixture is reduced by 26.79-24% and the BSFC diminutions with growing addition of ethanol from the CNSL hydrogen mixture. The BTE upsurges thru a rise in ethanol proportion with CNSL hydrogen mixtures. Finally, the optimum combination of ethanol with CNSL hydrogen blends led to the reduced levels of HC and CO emissions with trivial upsurge in exhaust gas temperature and NOx emissions. This paper reconnoiters the routine of artificial neural networks (ANN) to envisage recital, ignition and discharges effect.

This paper investigates the performance and emission characteristics of 20% cashew nut shell liquid (CNSL)-diesel blend (B20) in a direct injection diesel engine. The cashew nut shell liquid was prepared by pyrolysis method. The test was conducted with various nozzle opening pressures like 200 bar, 225 bar and 250 bar at different loads between no load to full load. The results showed that the brake thermal efficiency was increased by 2.54% for B20 with 225 bar at full load. The CO and smoke emissions were decreased by 50% and 14% respectively and the NOx emission were decreased slightly with 225 bar injection pressure compared with 200 bar and 250 bar at full load. On the whole, it is concluded that the B20 CNSL blend can be effectively used as a fuel for diesel engine with 225 bar injection pressure without any modifications.

The Impact

The purpose of this study is to investigate the impact of bio fuel enhancer additive added to 20% cashew nut shell liquid (CNSL) biodiesel blended with No.2 diesel fuel, in terms of the performance and exhaust emissions on a 4-cylinder naturally-aspirated direct-injection diesel engine. Experiments were conducted under five engine loads at a steady speed of 1500 rpm. The influence of blends on carbon monoxide (CO), nitrogen oxide (NO), carbon dioxide (CO2), hydrocarbon emission and smoke opacity were investigated. . The experimental results showed that the bio fuel enhancer additive improves the performance parameters and decreases CO emission by 13% and HC emission by 15% as compared to biodiesel. Bio Fuel Enhancer (BFE) additive reduces the NO emission remarkably by 55% as compared to biodiesel.

Vegetable oils are a potential alternative to partial or total substitution of diesel fuels. In this study, we used diethyl ether as an additive to investigate the possible use of increased percentages of biodiesel in diesel engine without any retrofitting. Biodiesel was made by pyrolysis process. Cashew nut shell liquid (CNSL) was selected for biodiesel production. Number 2 diesel fuel containing 20% biodiesel and 80% diesel fuel, is called here as B20. The effects of diethyl ether, blended with B20 in 5, 10, 15 % by volume were used in a single cylinder, four strokes direct injection diesel engine. The effect of test fuels on engine torque, power, brake specific fuel consumption, brake thermal efficiency, exhaust gas temperature, were ascertained by performance tests. The influence of blends on CO, CO2, HC, NO and smoke opacity were evaluated by emission tests. The experimental results showed that the exhaust emissions were fairly reduced for 10% diethyl ether with B20; especially the NO is reduced remarkably by 69.4% while comparing B20.
