the study of interactions of jet into cross flow at different longitudinal and transverse angles ofjet was studied. the following components were designed and constructed: a low velocity windtunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jetinjection, and a spatial rake to measure the total pressure. the tests were carried out atlongitudinal (α...

increase of environmental pollution and restricted emission legislations have forced companies to produce automobiles with lower air pollutants. in this respect, discharge of blowby gases into the environment has been prohibited and their recirculation into the combustion chamber is proposed as an alternative solution. in addition, using egr technique to control and reduce nitrogen oxides in in...

this study presents a computational study of mixture formation, flame front movement, combustion process and emission formation at the various spray angles and number holes in a direct injection diesel engine. this work is carried out in a direct injection om355 diesel engine at four and five holes with 130
, 135
and 140
spray angles. the amount of fuel injected per cycle is constant at all s...

the spray characteristics of the fuel greatly influence emissions from diesel engines. spray development plays a vital role in improving the combustion and emission characteristics of fuel because it directly affects the air- fuel mixture formation. the spray characteristics of fuel mainly depend on fuel injection process, fuel density, fuel viscosity, ambient pressure and temperature. among th...

An accurate fuel injection advance angle is an important parameter to obtain better fuel combustion index and emission index. Fuel injection advance angle is always deranged because of the wear of the injection nozzle matching parts, which has serious impact on diesel engine performance. How to measure the fuel injection advance angle easily and accurately is a problem for fault diagnosis of hi...
