The fuel temperature effect on the gas emissions when use as fuel diesel-palm +sunflower oil mixture

摘要

One of the major global problems is the air pollution, as it can harm humans, plants, animals and property. In the days before the proliferation of large cities and industry, nature's own systems kept the air fairly clean. Wind mixed and dispersed the gases, rain washed the dust and other easily dissolved substances to the ground and plants absorbed carbon dioxide and replaced it with oxygen. With increasing urbanization and industrialization, humans started to release more wastes into the atmosphere than nature could cope with. Since then, more pollution has been added to the air by industrial, commercial and domestic sources. Some of these pollutants can be created by indoor activities, such as cooking, smoking, car emissions, smokestacks and other industrial inputs into the atmosphere. Also the pollutant can be created by outdoor activities, such as smog and acid rain. The main aim of this essay is to examine the effect of temperature of fuel in the gas emissions that is used in four-stroke diesel engine. The temperatures of fuel that were used are 20°C, 30°C, 40°C, 50°C, 60°C, 70°C, 80°C. The engine was function on 1000 rpm, 1500 rpm, 2000 rpm, 2500 rpm, 2000 rpm, 1500 rpm, 1000 rpm (pyramid of rpm) when it uses diesel and diesel-50%F (80% palm oil +20% sunflower oil) mixtures as fuel. For those fuel temperatures the gas emissions of carbon monoxide (CO), hydrocarbons (HC), nitrogen monoxide (NO) and smoke are being examined.
