The use of biodiesel in running diesel has been called for, with a view to mitigating the environmental pollution, depletion, cost and scarcity associated with the use diesel in running diesel engine. So the need to characterize the emissions from these biodiesel, cannot be overemphasized, hence this paper presents the evaluation of the emissions of particulate matter (PM), carbon monoxide(CO), hydrocarbon(HC) and oxides of nitrogen (NOX) from diesel engine run on coconut oil biodiesel, its blends and diesel for comparison. The result of the evaluation showed that NOX emission increased with increase in percentage of the biodiesel in the blend, while PM, CO, HC decreased with increase in the percentage biodiesel in the blend. In comparison with diesel, diesel has the least emission of NOX and the highest emission of PM, CO and HC.Keywords: Diesel engine, diesel, coconut oil biodiesel, blends, emissions

Biodiesel Blend

Biodiesel is a viable substitute for petroleum-based diesel fuel. Its advantages are improved lubricity, higher cetane number and cleaner emission. Biodiesel and its blends with petroleum-based diesel fuel can be used in diesel engines without any signifi cant modifi cations to the engines. Data from the numerous research reports and test programs showed that as the percent of biodiesel in blends increases, emission of hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM) all decrease, but the amount of oxides of nitrogen (NOx) and fuel consumption is tend to increase. The most signifi cant hurdle for broader commercialization of biodiesel is its cost. In current fuel price policy in Indonesia (especially fuel for transportation), the higher percent of biodiesel in blend will increase the price of blends fuel. The objective of this study is to assess the optimum blends of biodiesel with petroleum-based diesel fuel from the technically and economically consideration. The study result recommends that 20% biodiesel blend with 80% petroleum-based diesel fuel (B20) is the optimum blend for unmodifi ed diesel engine uses.Keywords: biodiesel, emission, optimum, blend

Heavy Duty Diesel

Exhaust emissions from heavy-duty diesel engines have been legislated since the 1960’s and continue until 2010. Smoke emissions continue to be controlled but exhaust odor regulations were never promulgated. Gaseous emissions (oxides of nitrogen, carbon monoxide, hydrocarbons) were not regulated until 1973 and particulate matter first regulated in 1988. Emission regulations have been through several periods of cooperation between regulators and manufacturers but there have also been periods of conflict and lawsuits. The most recent issues are with the October 2002 requirements of the Consent Decrees signed by seven diesel engine manufacturers and USEPA/US DOJ/CARB. Also the 2007/2010 regulations are under review.

The Impact

Abstract The present investigation accentuates the impact of Undi biodiesel blended Diesel on combustion, performance, and exhaust fume profiles of a single-cylinder, four-stroke Diesel engine. Five Undi biodiesel-Diesel blends were prepared and tested at four variable loads over a constant speed of 1500 (±10) rpm. The Undi biodiesel incorporation to Diesel notably improves the in-cylinder pressure and heat release rate of the engine. The higher amount of Undi biodiesel addition enhances the brake thermal efficiency and brake specific energy consumption of the engine. In addition, the Undi biodiesel facilitates to reduce the major pollutants, such as brake specific unburned hydrocarbon, brake specific carbon monoxide, and brake specific particulate matter emissions with slightly higher brake specific oxides of nitrogen emissions of the engine. To this end, a trade-off study was introduced to locate the favorable Diesel engine operating conditions under Undi biodiesel-Diesel strategies. The optimal Diesel engine outputs were found to be 32.65% of brake thermal efficiency, 1.21 g/kWh of brake specific cumulated oxides of nitrogen and unburned hydrocarbon, 0.94 g/kWh of brake specific carbon monoxide, and 0.32 g/kWh of brake specific particulate matter for 50% (by volume) Undi biodiesel share blend at 5.6 bar brake mean effective pressure with a relative closeness value of 0.978, which brings up the pertinence of the trade-off study in Diesel engine platforms.

The primary objective of this study is to discover the effects of injection timing on performance, emission and combustion characteristics effect of advanced and retarded injection timing of the engine fuelled with mahua oil biodiesel blends. The engine performance, combustion and emission characteristics of the mahua oil biodiesel blends (B20, B40, B60, B80and B100) are investigated in this experimentation without any modification of the diesel engine. At this advanced pressure t he efficiency of engine by means of CO, Unburned HC gases and smoke emissions with higher oxides of nitrogen was observed compared to diesel. The obtained results are compared with a neat diesel and mahua oil biodiesel blends are shown through the graphs. From this study, identifies optimum fuel blend of this work. Thus, the combustion of duration is similar in all variance in pressure. This research paved a way to bio-diesel in mahua oil mixture and draws best outcome in emission less and to maintain eco-friendly environment.

Diesel engines are widely used for their low fuel consumption and better efficiency. Fuel conservation, efficiency and emission control are always the investigation points in the view of researchers in developing energy system. India to search for a suitable environmental friendly alternative to diesel fuel. The regulated emissions from diesel engines are carbon monoxide (CO), Hydrocarbons (HC), NOx and Particulate matter. It creates cancer, lungs problems, headaches and physical and mental problems of human. This paper focuses on the substitution of fossil fuel diesel with renewable alternatives fuel such as Biodiesel. Biodiesel is much clear than fossil diesel fuel and it can be used in any diesel engine without major modification. The experiment was conducted in a single-cylinder four-stroke water-cooled 3.4 kW direct injection compression ignition engine fueled with non-edible Pungamia oil biodiesel blends. The experimental results proved that up to 40% of Pungamia oil biodiesel blends give better results compared to diesel fuel. The AVL 444 di-gas analyzer and AVL 437 smoke meter are used to measure the exhaust emissions from the engine. The observation of results, non-edible Pongamia biodiesel blended fuels brake thermal efficiency (3.59%) is improved and harmful emissions like CO, unburned HC, CO2, Particulate matter, soot particles, NOx and smoke levels are 29.67%, 26.65%, 33.47%, 39.57%, +/- 3.5 and 41.03% is decreased respectively compared to the diesel fuel. This is due to biodiesel contains the inbuilt oxygen content, ignition quality, carbon burns fully, less sulphur content, no aromatics, complete CO2 cycle.
