In this study, the performance and emission characteristics were analyzed by using rubber biodiesel in a single cylinder direct injection diesel engine. The experiments were conducted using different combination of fuels such as 20%, 50% of biodiesel blends by volume (B20 and B50) with pure diesel fuel, pure biodiesel (B100) and pure diesel fuel (B0). The performance parameters were obtained for different load conditions from No load to Full load at rated rpm. Results indicated that the higher brake thermal efficiency, Mechanical efficiency, reduced specific fuel consumption obtained for biodiesel blend of B20, compared to other blends and diesel fuel.

Biodiesel is one of the best alternative fuels to Diesel engine among other sources due to having potential to reduce emissions. Biodiesel is a renewable, biodegradable and environment friendly fuel in nature. The advantages of biodiesel are lower exhaust gas emissions and its biodegradability and renewability compared with petroleum-based diesel fuel. The energy of the biodiesel can be released more efficiently with the concept of semi adiabatic (thermal barrier coated piston) engine. The objective of this study is to investigate the performance and emission characteristics of a single cylinder direct injection Diesel engine using 25% biodiesel blend (rubber seed oil methyl ester) as fuel with thermal barrier coated piston. Initially the piston crown was coated with alumina (Al2O3) of thickness of 300 micron (0.3 mm) by plasma coating method. The results revealed that the brake thermal efficiency was increased by 4% and brake specific fuel consumption was decreased by 9% for B25 with coated piston compared to un-coated piston with diesel. The smoke, CO, and HC emissions were also decreased for B25 blend with coated piston compared with the uncoated piton engine. The combustion characteristics such as peak pressure, maximum rate of pressure rise, and heat release rate were increased and the ignition delay was decreased for B25 blend for the coated piston compared with diesel fuel.

Injection Pressures

Fuel injection pressures in diesel engines play an important role to distribute the fuel jet quickly and to form a uniform gas mixture after fuel injection in order to reduce fuel consumption and emissions. In this study, an attempt has been made to study the effect of injection pressure on a single cylinder direct injection diesel engine fueled with diesel, diesel – bael biodiesel blend (B20) and methyl ester of bael (Aegle marmelos) seed oil with injection pressures of 220,230,240 and 250 bar. Increasing the injector opening pressure has been found to increase brake thermal efficiency and reduce CO, HC and smoke emissions significantly. The optimum injection pressure was found to be 240 bar for bael seed biodiesel.

This study aims to find the optimum performance and emission characteristics of single cylinder variable compression ratio (VCR) engine with different blends of Annona methyl ester (AME) as fuel. The performance parameters such as specific fuel consumption (SFC), brake thermal efficiency (BTE), and emission levels of HC, CO, Smoke, and NO x were compared with the diesel fuel. It is found that, at compression ratio of 17: 1 for A20 blended fuel (20% AME + 80% Diesel) shows better performance and lower emission level which is very close to neat diesel fuel. The engine was operated with different values of compression ratio (15, 16, and 17) to find out best possible combination for operating engine with blends of AME. It is also found that the increase of compression ratio increases the BTE and reduces SFC and has lower emission without any engine in design modifications.

Performance And Emission

This paper presents a comparative analysis of the diesel engine performance and emission characteristics, when operating on diesel fuel and various diesel-biodiesel (B10, B20, B40, B60) blends, at various loads and engine speeds. The experimental tests were performed on a four-stroke, four-cylinder, direct injection, naturally aspirated, 60 kW diesel engine D-243. The in-cylinder pressure data was analysed to determine the ignition delay, the Heat Release Rate (HRR), maximum in-cylinder pressure and maximum pressure gradients. The influence of diesel-biodiesel blends on the Brake Specific Fuel Consumption (bsfc) and exhaust emissions was also investigated. The bench test results showed that when the engine running on blends B60 at full engine load and rated speed, the autoignition delay was 13.5% longer, in comparison with mineral diesel. Maximum cylinder pressure decreased about 1–2% when the amount of Rapeseed Methyl Ester (RME) expanded in the diesel fuel when operating at full load and 1400 min–1 speed. At rated mode, the minimum bsfc increased, when operating on biofuel blends compared to mineral diesel. The maximum brake thermal efficiency sustained at the levels from 0.3% to 6.5% lower in comparison with mineral diesel operating at full (100%) load. When the engine was running at maximum torque mode using diesel – RME fuel blends B10, B20, B40 and B60 the total emissions of nitrogen oxides decreased. At full and moderate load, the emission of carbon monoxide significantly raised as the amount of RME in fuel increased.

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.
