Global warming and climate change are the motives to find a solution for emission reduction of diesel engines. Bioethanol is renewable fuel which can be used in diesel engine as a part of biodiesel-diesel blends. The effect of bioethanol on the emission performance of diesel engine for rapeseed biodiesel-diesel blends as a function of engine load is evaluated in this paper. KDE 6500E diesel generator is used for this purpose. Carbon monoxide (CO), unburned hydrocarbons (HC), oxygen (O2) and carbon dioxide (CO2) emissions are recorded with the help of VLT-458 exhaust gas analyzer. Blends with higher concentrations of bioethanol have shown lower CO emissions while HC emissions increase with the increase in bioethanol concentration in the blends. CO2 emissions are recorded more at higher loads for all types of biodiesel and bioethanol concentrations than that of diesel fuel.

Rapid depletion of conventional fuels and growing requirements has led the researchers towards alternative sources like bio-fuels. Present work discusses the suitability of those bio-fuels in a naturally aspirated diesel engine by comparing the performance. Initially, the effect of bio-fuels on fuel consumption and thermal efficiencies are studied and compared with diesel. Thermal efficiency is improved and specific fuel consumption reduced, particularly with karanja oil when compared to diesel. Secondly, the energy balance of the engine is compared. Heat losses are found reducing in bio-fuels due to viscosity and heat rejected to coolant is found less with karanja oil when compared to diesel. Also, the engine emissions, particularly oxides of carbon, nitric oxides, and unburned hydrocarbons from bio-fuels and diesel are sensed using five-gas analyzer and compared. NOx and CO2 emissions are slightly more in bio-fuels when compared to diesel, while CO and HC emissions are less for bio-fuels.

Gas Recirculation

In this study the effect on exhaust gases of a diesel engine fuelled by biodiesel and coupling Exhaust Gas Recirculation (EGR) has been done. EGR is a pre-treatment technique to trim down NOx from diesel engines as it is expected to reduce the flame temperature and the oxygen concentration in the combustion chamber. Fossil fuels so-called biodiesel is picked as the blending fuel. Existence of oxygen in Biodiesel aids complete combustion and anticipated to reduce CO and HC emissions. Exhaust Gas Recirculation technique can capably reduce the amount of NOx. EGR may tend to increase the CO and HC emissions, biodiesel which has higher oxygen content is blended to diesel so that it may compensate CO and HC emissions. The performance and emission characteristics of EGR along with biodiesel in a diesel engine are discussed.

Biodiesel derived from nonedible feed stocks such as Mahua, Jatropha, Pongamia are reported to be feasible choices for developing countries including India. This paper presents the results of investigation of performance and emissions characteristics of diesel engine using Mahua biodiesel. In this investigation, the blends of varying proportions of Mahua biodiesel and diesel were prepared, analyzed compared with the performance of diesel fuel, and studied using a single cylinder diesel engine. The brake thermal efficiency, brake-specific fuel consumption, exhaust gas temperatures, Co, Hc, No, and smoke emissions were analyzed. The tests showed decrease in the brake thermal efficiencies of the engine as the amount of Mahua biodiesel in the blend increased. The maximum percentage of reduction in BTE (14.3%) was observed for B-100 at full load. The exhaust gas temperature with the blends decreased as the proportion of Mahua increases in the blend. The smoke, Co, and No emissions of the engine were increased with the blends at all loads. However, Hc emissions of Mahua biodiesels were less than that of diesel.

This paper presented results of a study on emission characteristics of diesel engines. A numerical simulation model for a diesel engine was established by GT-POWER. Emission species studied include of NO, CO and HC. The developed model was validated by engine tests under laboratory condition. Based on the model, the simulation changing the variable parameters including injection timing, intake air temperature and EGR (exhaust gas recirculation) ratio were carried out to study their effect on emissions. The simulation results showed that with the decrease of CA BTDC, intake air temperature, compression ratio and EGR ratio respectively, the NO emission decreased. However, the CO and HC emissions increased.

Gas Recirculation

An experimental study was conducted to determine the performance and exhaust emission characteristics of an automotive direct injection dual-fuelled diesel engine. Natural gas was used such that 65 per cent of engine brake power was supplied from compressed natural gas and the rest was supplied from diesel fuel. The objective of this work is to investigate the possibility of decreasing exhaust emission with the lowest performance sacrifice. At part loads, a dual-fuelled engine inevitably suffers from lower thermal efficiency and higher carbon monoxide (CO) emission. This is mainly due to leaner mixture and incomplete combustion, which is a consequence of the smaller amount of pilot fuel. To resolve these problems, the e ects of cooled exhaust gas recirculation (EGR) were investigated. The experimental results show that the application of EGR, at higher loads with 10 per cent EGR and at part loads with 15 per cent EGR, can considerably reduce NO x and other exhaust emissions such as unburned hydrocarbons, CO and soot. Results show that the performance parameters almost remain at the baseline engine level.
