The Engine Performance of a Diesel Engine and the Research of the Effect of Fuel Additives on Engine Oil and Engine Parts

In this study, the development of properties of diesel fuel, and the effect of methanol fuel on engine performance and on engine parts have been researched. For this purpose, this study consists of the analyses respectively in that organometal MnO2 synthesis, fuel analysis, engine tests involving the values of the engine performance and the effect of methanol used in this study on engine lubricating oil have been examined. Experiments have been made by adding methanol into 1 liter fuel in the rates of 5%,10% and 15% under 200 bar pressure of the injector spray in the diesel engine having 4-cylinder with direct-injection. The 1% of dodecanol has been added to each one of the fuels mixtures with methanol-diesel in order to prevent the phase separation. The effects of methanol fuel adding to diesel fuel in certain properties on engine performance, engine lubricating oil, and on engine components has been researched. In addition, the organometallic compounds of Mn have been synthesized and their solutions have been prepared in order to improve the fuel properties. The effectives on the values of engine performance of the additive, which is effective on the freezing point of fuel and cetane number, have been tried to determine by using methanoldiesel fuel with Mn02-diesel fuels.
