Pre-heating Fuel for Charge Homogeneity to Improve Combustion

Abstract – The idea of the automobile engine that people have is of one that is bygone. The automobile engine today is the pinnacle of engineering expertise, implementing the best of technologies and undergoing the best of manufacturing processes to make the closest possible achievement to perfection, from design to combustion. The art of perfection though starts much before the process itself. In case of the automobile engine, the process is the 4-Stroke cycle that most engines go through and the art we are referring to is attaining homogeneity in charge. Homogeneous charge in an Internal Combustion Engine refers to the complete mixture of fuel (Petrol) and air, entering the cylinder. Ideally this would mean the complete dispersion of the atomised fuel in air. This as a result reduces the overall efficiency of the engine. To help achieve the required atomisation, reducing the Surface Tension of the fuel is a potential solution. On reduction of Surface Tension the atomisation is enhanced, possibly reaching the ideal value. This can be achieved by heating the fuel to an operating temperature for which heat can be extracted from a potential source, namely the Exhaust
Manifold.

A. By-products are formed in the form of smog as a result of supplementary reactions such as NOx or the various oxides of nitrogen, the nature of these reactions is endothermic, higher the temperature, greater the emissions of NOx
N2 + O2 --> 2 NO (Δh = 175.728kJ)
½N2 + O2 --‐--‐> NO2 (Δh = 33.9kJ)
B. Incomplete combustion resulting in the formation of
CO or carbon monoxide a highly poisonous and good oxidizing agent. The formation of CO is favoured at lower temperatures contrary to NOx
H-C + ½O2 --> CO + ½H2O (Δh = -110.527kJ*)
C. Some hydrocarbons are not burnt due to lack of successive collisions between oxygen and fuel.
D. Based on our reading, observation and calculation, we have the

    EFFICIENCY INCREASING SYSTEM BY USING PREHEATING METHOD EFFICIENCY INCREASING SYSTEM BY USING PREHEATING METHOD METHODOLOGY The concept of increasing the fuel efficiency of a petrol engine in this project, is to pre-heat the intake air which is flowing through the carburetor. The humidity in the atmospheric air affects the petrol vapourisation in the carburettor. Therefore, by pre-heating the inlet air to the carburettor for a considerable amount, the vapourisation can be ease and in turn…

    Alternative Fuels People in America do not realize the fact that driving their vehicle is one of the regular activities that they do that has one of the largest impacts on the earth. With more and more cars in use each day, the more fossil fuels are called for. Fossil fuels are natural fuels that were formed from the remains of living organisms. These fossil fuels typically take millions of years to be formed. Since most fossil fuels are being imported due to it taking a huge amount of time…

    6 Ocober 2013 Fossil Fuels and Alternate Energy Sources In the early 1900s, fossil fuels were the primary source of energy, but in more recent times with reserves diminishing and global warming becoming a major issue, we are forced to develop alternate sources of energy. According to Melosi, Governments became aware of the effects of fossil fuels as early as the 1950s, and in an attempt to combat this, they passed laws to try and lower the amount of pollution it caused (The Automobile and…

    Fossil Fuels: Rape of Nature {Student name here} {Class name here} {Professor Name here} {Due Date} Fossil Fuels, which include coal, oil, and natural gas, are a non-renewable energy source that were formed from the decomposition of plants and animals that were deposited in the Earth around 300 million years ago. These fossil fuels, after being removed from the Earth, are converted into energy and this energy is essential to modern society (Chughtai & Shannon, 1998). Over 85 percent…

    Introduction to the Magnetic Treatment of Fuel By R.J. Kita Hydrogen is the lightest and most basic element known to man. With its simple structure comprised of only one proton and one electron, it is one of the major constituents of all hydrocarbon based fuels. By studying the response of hydrogen with respect to magnetic fields and the accompanying increased energy output, much can be learned and applied to other related fuels. In the oxidation/combustion of hydrocarbon fuels, it is the outer shell of the…

    Energy in the form of fossil fuels, can it meet all of society’s needs or is it time for us to look at other alternatives before it is too late? The increasing pollution and price of energy has once again ignited the debate about options for future energy. Fossil fuels are hydrocarbon deposits also known as coal, crude oil and gas derived from the remains of organic prehistoric plants and animals. They have taken many millions of years to form. Coal is ground to a fine dust when crushed and…
