Research has been conducted to determne the effect of using biodiesesl on emission and fuel efficiencyin diesel engine vehicle. Testing was conducted on vehicle 2500 cc fuelled with 2 base fuel of diesel fuel 48 and diesel fuel Euro4 standard in which both of base fuel was blended with biofuel in form of FAME and HVO with ratio of 30% (B30). Test method was using United Nations Economic Commission for Europe, yakni UN ECE R83 and R10. The results showed the addition of 30% FAME and 30% HVO in petrodiesel and diesel fuel 48, was able to reduce CO and HC emissions. While for NOx emissions there has not been a significant change. The addition of FAME to both base fuels was able to reduce particulate emissions, but conversely with the addition of HVO, particulate emissions were higher. The addition of FAME and HVO to petrodiesel has not been able to save fuel consumption, instead there was a slight increase of 0.1% for FAME and 0.5% HVO. Meanwhile for diesel fuel 48 the addition of FAME is more economical around 5.5%, while the addition of HVO is a little extravagant around 1.8%.%.

Co Emission

Emission characteristics of an electronic-controlled high pressure common-rail diesel engine with low-blend Gas-to-liquids (GTL) and low-blend biodiesel fuels are studied. Pure diesel fuel, G10 fuel (10% GTL blend with diesel fuel) and B10 fuel (10% biodiesel blend with diesel fuel) are used in this research. The results show that torque of the engine with pure diesel fuel is higher than G10 fuel, and B10 fuel is the lowest. Compared to the pure diesel fuel, the brake specific fuel consumption (BSFC) of the engine with G10 fuel decreases, but the B10 fuel increases slightly. Hydrocarbon (HC) emissions of the engine with G10 fuel or B10 fuel are lower than the pure diesel fuel, and the carbon monoxide (CO) emission increases slightly, and nitrogen oxides (NOx) emissions have no distinct change. Compared to the G10 fuel, the CO and HC emissions of the engine with B10 fuel are lower.

Fuel Formulation

The primary objective of this work is to reduce the particulate matter (PM) or smoke emission and oxides of nitrogen (NOx emissions) the two important harmful emissions and to increase the performance of diesel engine by using oxygenated additives with diesel as blend fuel. Formulation of available diesel fuel with additives is an advantage than considering of engine modification for improvement of higher output. From the available additives, three oxygenates are selected for experimentation by considering many aspects like cost, content of oxygen, flashpoint, solubility, seal etc. The selected oxygenates are Ethyl Aceto Acetate (EAA), Diethyl Carbonate (DEC), Diethylene Glycol (DEG). These oxygenates are blended with diesel fuel in proportions of 2.5%, 5% and 7.5% by volume and experiments were conducted on a single cylinder naturally aspirated direct injection diesel engine. From the results the conclusion are higher brake power and lower BSFC obtained for DEC blends at 7.5% of additive as compared to EAA, DEG and diesel at full load. In case of DEC blends the smoke emission is lower, whereas NOx emissions are very low in case of EAA additive blend fuels. The DEC can be considered is the best oxygenating additive to be blend with diesel in a proportion of 7.5% by volume.

The City

In the 1960s, Addis Ababa experienced a construction boom, spurred by its new international stature as the seat of both the United Nations Economic Commission for Africa and the Organization of African Unity. Working closely with Emperor Haile Selassie, expatriate architects played a major role in shaping the Ethiopian capital as a symbol of an African modernity in continuity with tradition. Haile Selassie's Imperial Modernity: Expatriate Architects and the Shaping of Addis Ababa examines how a distinct Ethiopian modernity was negotiated through various borrowings from the past, including Italian colonial planning, both at the scale of the individual building and at the scale of the city. Focusing on public buildings designed by Italian Eritrean Arturo Mezzedimi, French Henri Chomette, and the partnership of Israeli Zalman Enav and Ethiopian Michael Tedros, Ayala Levin critically explores how international architects confronted the challenges of mediating Haile Selassie's vision of an imperial modernity.
