Diesel engineers are major sources of prime movers, which are widely used for small and large-scale power generation and transportation purposes. These engines are widely used owing to its high power output and general thermal efficiency. In spite of these benefits diesel engines cause serious environmental and human discomforts on global scale. The important pollutants from a diesel engine are NOx HC and particulate matter. These particulates are inhalable, capable of traveling deep into lungs and causes diseases. As a result of this governments and health organizations have tightened the standards for pollutants from diesel engine. Hence it has becomes important that these particulate matter have to be reduced or eliminated from the exhaust f diesel engine. This project aims to reduce the particulate emission in the diesel engine exhaust and to improve the performance of the engine. A literature survey was conducted revealed that using fuel additives, which oxygenate the fuel and reduces the emissions, can reduce the particulate emission. Additives like Ethylene glycol di-Me ether, Diethylene glycol di-Me ether, Diethylene glycol di-Et ether, Bu ether, Aliphatic alc., Aromatic alc. and Glycol ethers were used by various researchers in this field, as fuel additives. Encouraging results were obtained and some of them are reported in this project. In this oxygenates, ethers behave better than alc.’s. Hence for this present work some of the ethers were selected which were not much tried and detail were not much known. Three additives were selected for the fuel. Diethylene glycol mono Bu ether, Diethylene glycol di-Bu ether, and Diethylene glycol mono-n-hexyl ether ether are the additives selected. A single cylinder direct injection diesel engine (Greaves cotton engine) was selected for conducting the tests. These oxygenates were added in different quantities to the selected base fuel, diesel. Load tests and speed tests were conducted first with the sole fuel (diesel) and then with the smoke emissions were deduced to a very great extent, the maximum reduction was obtained while using 4ml of Diethylene glycol mono-n-hexyl ether. The smoke level is reduced from 70HSU to 29HSU, the particulate matter is reduced from 2.801 g/h to 1.512 g/h and the smoke conversion efficiency is found out as 58.57% at full load. A slight decrease in fuel consumption and about 1 to 2% increase in brake thermal efficiency was found out from the experiment conducted, for various loads and speeds which shows obviously an improvement in the performance. The other two additives also shows the same trend except that these values slightly differ indicating that Di-Bu ether comes as second good additive and Diethylene glycol mono Bu ether as third good additive. Detailed results are reported in the results and discussions chapter and conclusions at the end. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Related Products of 112-59-4).
2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Related Products of 112-59-4
