Combustion Characteristics of a Diesel-hydrogen Dual Fuel Engine
Among the alternative fuels, hydrogen shows great potential in the near future. In the present study, hydrogen utilization as diesel engine fuel was investigated. Hydrogen can not be used directly in a diesel engine due to its autoignition temperature higher than that of diesel fuel. One alternative method is to use hydrogen in enrichment or induction. To investigate the combustion characterist...
متن کاملTrends of Air Fuel Ratio on Engine Performance of Four Cylinder Direct Injection Hydrogen Fueled Engine
The present study focuses on the effect of air-fuel ratio on the performance of four cylinder hydrogen fueled direct injection internal combustion engine. GT-Power was utilized to develop the model for direct injection engine. Air-fuel ratio was varied from rich limit to a lean limit. The rotational speed of the engine was varied from 1250 to 4500 rpm. The acquired results shown that the air fu...
متن کاملExhaust Emission Analysis of an Internal Combustion Engine Fuelled with Hydrogen-Ethanol Dual Fuel
The work presented in this paper is an attempt to evaluate the exhaust emission characteristics of a hydrogen-ethanol dual fuel combination with different percents of hydrogen substitutions (i.e. 0-80 % by volume and of 20 % increment ) at three different compression ratios of 7:1, 9:1 and 11:1. Experimental investigations have been carried out on a computer interfaced with; four-stroke cycle, ...
متن کاملReduction of emissions and fuel consumption of diesel engine by using common rail fuel injection and aftertreatment systems
In this experimental study, the fuel system of the OM364 diesel engine manufactured by IDEM company, which operates in the basic mode with inline fuel pump and mechanical governor control, is upgraded to a common rail system with electronic control by the ECU. Also, emmssion of exhaust gases is reduced by SCR and DOC catalysts then performance and emmission parameters of engine are compared i...
متن کاملchannel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
