A model for oil consumption due to in-cylinder evaporation of oil in reciprocating engines, has been developed. The model is based on conservation of mass and energy on the surface of the oil film left on the cylinder by a piston ring pack, at the oil/gas interface, and also conservation of energy within the oil film and cylinder/coolant interface. The model is sensitive to in-cylinder conditions and is part of an integrated model of ring pack performance, which provides the geometry of the oil film left by the ring pack on the cylinder. Preliminary simulation results indicate that a relatively small but not insignificant fraction (2-5%) of the total oil consumption may be due to evaporation losses for a heavy duty diesel at the rated condition. The evaporation rate was shown to be sensitive to oil grade and upper cylinder temperature. Much of these losses occur during the non-firing half of the cycle. Under certain conditions these losses could be higher than those for the firing half of the cycle and thus may have important implication for control of hydrocarbon emissions. © 1992 Society of Automotive Engineers, Inc.

Experimental investigation of oil accumulation in second land of internal combustion engines İÇÖZ, TUNÇ; Dursunkaya, Zafer (ASME International, 2005-01-01) 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 constru...
An Experimental study on the effects of different chloride sources on the properties of API Class G cement Ramazanoğlu, Özge; Yaman, İsmail Özgür; Akın, Serhat; Department of Cement Engineering (2014) In the petroleum industry, oil well cements are used in the form of slurries during the construction of oil or natural gas wells. Preserving the integrity of the well and the casing, providing zonal isolation are some of the uses of these special cements. Oil well cement slurries used in the petroleum industry are subjected to different exposure conditions than ordinary Portland cement slurries used in the construction industry. Therefore, oil well cements are required to possess different engineering prope...
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...
An experimental study on single well steam assisted gravity drainage Akın, Serhat (2000-01-01) Steam assisted gravity drainage (SAGD) is one of the more popular enhanced oil recovery method of producing heavy oil and bitumen. In conventional SAGD approach, steam is injected into a horizontal well located above a horizontal producer. A steam chamber grows around the injection well and displaces heated oil toward the production well. There are several variations of this process: vertical injector-horizontal producer and singlewell (SW) SAGD where only one horizontal well is used by injecting steam from...
Development of a screening model for polymer flooding in multi-layer reservoirs ZarePakzad, Negar; Durgut, İsmail; Artun, Emre; Department of Petroleum and Natural Gas Engineering (2018) Polymer flooding is a chemical enhanced oil recovery method which aims to increase oil production from a water flooded oil reservoir by increase in water viscosity and reduction in water-oil mobility ratio. These changes result in significant increase in sweep efficiency of water comparing with water-only flooding technique. The objective of this study is to analyze the behavior of multilayer reservoirs under polymer flooding process, considering effects of reservoir characteristics, polymer properties and ...
