Blowback of engine oil suspended in combustion gases, when the gas flows from the piston second land back into the combustion chamber is believed to contribute to oil consumption and hydrocarbon emissions in internal combustion engines. Oil accumulation in the region between top and second compression rings is a factor that influences this phenomenon. The effects of individual parameters, such as oil film thickness and viscosity, however have still not been understood. The present study was aimed at constructing an experimental setup to study the effect of oil film thickness on oil accumulation in the second land of internal combustion engines. Due to the inherent difficulties of experimentation on production engines, a modeled piston-cylinder assembly was constructed. Total oil accumulation in the modeled second land after a single piston stroke was measured and compared to oil consumption in operating engines. [DOI: 10.1115/1.1805011]

Experimental investigation of an oil loss mechanism in internal combustion engines Sezer, Ahmet; Dursunkaya, Zafer; Department of Mechanical Engineering (2010) Oil loss mechanisms in internal combustion engines have been subject to many researches. By the help of technological developments effects of several problems due to oil losses were examined and tried to be reduced. Environmental pollution and performance loss are important issues that oil consumption in internal combustion engines contribute. In this study the effects of individual parameters on the oil accumulation in 2nd land crevice of internal combustion engines, volume between top compression rings, w...
Analytical investigation of wet combustion process for heavy oil recovery Bağcı, Ali Suat (Informa UK Limited, 2004-12-01) Analysis of combustion tube data produced from experiments performed under realistic reservoir conditions is currently the most valid method of investigating in-situ combustion process. In this study, the optimization of water-air ratio for B. Kozluca heavy crude oil, and the comparison of the performance of dry and wet forward combustion processes were studied. An analytical model was used to extend the laboratory results so that the oil production and steam zone volume can be estimated under field conditi...
Influence of coal briquette size on the combustion kinetics Altun, Naci Emre; Bagci, AS (Elsevier BV, 2004-08-15) In this study, the effects of one of the most important parameters in coal briquetting process, the briquette size, on the combustion behaviour of coal briquettes were determined from the view of combustion kinetics, i.e. their liability to ignite and combust. Effect of size on the combustion kinetics was treated by two different approaches. The first one consists of combustion kinetics experiments with briquettes of increasing sizes, thus of expanding volumes. In the second phase, briquette dimensions were...
Numerical simulations of gas production from Class 1 hydrate and Class 3 hydrate in the Nile Delta of the Mediterranean Sea MEREY, ŞÜKRÜ; Longinos, Sotirios Nik (Elsevier BV, 2018-04-01) Gas hydrate reservoirs are considered as near-future energy resources in the world. As well as the many places in the world, there is also gas hydrate potential in the Mediterranean Sea. In this study, by using the literature data, it was aimed to understand whether the Mediterranean Sea includes necessary parameters for producible gas hydrate reservoirs. It was shown that the Mediterranean Sea contains all of these parameters (source gas, appropriate pressure and temperature, coarse sand potential, etc.). ...
INCIDENTAL RELEASE OF BITUMEN DURING OIL SHALE GRINDING AND IMPACTS ON OIL SHALE BENEFICIATION Altun, Naci Emre (Estonian Academy Publishers, 2009-01-01) The particle surface characteristics of oil shale and the changes in these characteristics with increasing fineness were determined. FTIR and electro-kinetic studies showed that the surfaces of oil shale particle were controlled by oxygen-rich polar groups. FTIR and XPS studies showed that with increasing fineness the polar oxides decreased and organic surface groups increased at grind sizes finer than 100 microns. Flotation was used to view the impact of the changes in surface characteristics on oil shale ...
