“…On the other side, water particles are converted in the shape of tiny particles, which passes to improve air fuel mixing. Simultaneously, soot emissions get also reduced due to proper air fuel mixing [32][33][34][35][36][37][38] and enhanced air fuel mixing reduces CO and HC mass fraction, see Fig. 7(b).…”

“…The water particles absorb heat of vaporization in the form of latent and sensible heat, which results to low incylinder temperature. Thus, Low incylinder temperature produces less NO emissions [32]. In some studies, NO and soot emissions can be brought down simultaneously by water emulsion method [33][34][35].…”

“…[10] ve Wang ve ark. [11] suyun yüzey gerilmesinin yakıttan küçük olması nedeniyle suyun silindir içerisinde yakıtı daha küçük parçalara bölünmesinde etkili olduğunu belirmişlerdir. Bu sebepten dolayı yanmaya katılan yüzey alanına bağlı olarak yanma veriminde artmaların meydana geldiğini belirmişlerdir.…”

ÖZBu çalışmada, direk enjeksiyonlu bir dizel motorunda buhar ve suyun yanma odasına farklı şekillerde gönderiminin motor performans parametreleri ve NOx emisyonlarına etkisi deneysel olarak incelenmiştir. Su yanma odasına; farklı oranlarda stabilize emülsife yakıt (E10, E15, E20), 20 o C sıcaklıkta emme manifolduna sıvı fazda (S10, S15, S20) enjeksiyonu ve 133 o C sıcaklıkta buhar fazında emme manifolduna farklı oranlarda (B10, B15, B20) püskürtülmesi suretiyle 3 farklı şekilde gönderilmiştir. Buhar, egzoz devresine bağlanan bir eşanjör ile egzoz kayıp ısısından üretilmiştir. Emülsife yakıtların hazırlanmasında, faz ayrışmasını önlemek için surfaktan (yüzey aktif madde) kullanılmıştır. Deneyler tek silindirli, su soğutmalı, direkt enjeksiyonlu bir dizel motorunda tam yük şartlarında gerçekleştirilmiştir. Deneyler sonucunda farklı su gönderme yöntemleriyle elde edilen veriler standart motor verileri ile performans parametreleri ve NOx emisyon değerleri açısından karşılaştırılmıştır. Motorda kullanılan tüm su gönderme yöntemlerinde NOx emisyonlarında standart motor verilerine göre dikkate değer oranda azalmaların meydana geldiği tespit edilmiştir.Anahtar Kelimeler: buhar enjeksiyonu, su enjeksiyonu, emülsife yakıt, motor performansı, NOx Investigation of the effects of steam and different water introduction methods to a direct injection diesel engine on performance and NOx emissions ABSTRACTIn this study, the effects of steam and different water introduction methods to a direct injection diesel engine on performance and NOx emissions experimentally investigated. Water was introduced combustion chamber, different ratios stabilized emulsified fuels, at 20 o C temperature liquid phase and 133 o C temperature gas phase (water steam) was injected inlet manifold, with three different methods. Water steam was produced from waste energy of exhaust gas stream. For the preparation of emulsified fuels, to stabilize the emulsified fuels, a 2% by mass surfactant mixture was used. The tests were conducted on a single-cylinder water cooled direct injection (DI) diesel engine under full load conditions. As a result of experiments, the data was obtained with different water introduction method, based on the standard engine data were compared in terms of performance parameters and NOx emissions. It was observed that there were remarkable decreases of NOx emissions for all of the water introduction methods compared to the standard engine values.

“…Moreover, Cornet and Nero [15] demonstrated that the use of an emulsion notably influences the increase of fuel efficiency and decrease of the temperature of emitted exhaust gases. During studies on the combustion of water-fuel emulsions also, the decrease of nitrogen oxides emissions has been observed [16,17].…”

Liquefied hydrocarbon gases, containing mostly the mixture of C3-C4 hydrocarbons, in many countries serve as an important source of energy, also for internal combustion engines. On a world scale, at present, about 270 million tonnes of this fuel is produced, of which motorization consumes 26 million tonnes (~10%). Poland is one of these countries, where LPG is a popular engine fuel. Annual consumption of so called autogas is about 1.7 million tonnes with increasing tendency. Almost 3 millions of cars with bifuel engines, mostly spark ignition ones, are driven on Polish roads. An extensive logistical infrastructure accompanies the development of the use of this type of fuel in Poland. There are numerous production companies in Poland working to meet the needs of this branch of industry, as well as a modern service base. Intensive research and development works in this field are carried out. The exceptional advantages of LPG as an alternative engine fuel have been highly appreciated in Poland. These advantages result mainly from the simplicity of its production. Relatively low investment costs and energy consumption are needed to produce high-quality fuel by degasolining of natural gas or crude oil stabilization. LPG is produced as a byproduct in numerous petroleum refining processes and its quality is relatively close to the engine fuel requirements. The source of aliphatic hydrocarbons falling into LPG range can also be the processes of biomass conversion and in the near future, fermentation processes. Environmental advantages of LPG are primarily very low emission of almost all toxic components of engine exhaust gases compared to gasoline or diesel fuel. In this chapter the results of research works aimed at the improvementof exploitation properties, logistics and LPG combustion processes in spark ignitionengines are presented. In this area, anti-corrosion additives for LPG of very high effectiveness were obtained and tested. Also, with the help of additives, the problem of water separating from LPG during storage and transport in tankers has been solved. A multifunctional additive was obtained giving LPG adequate lubricity and detergent properties. The influence of water on the process of LPG combustion in a gasoline fuelled engine as well ways to supply water to the combustion zone are being studied. A mathematical model is being elaborated, precisely describing correlations between density and chemical composition of LPG as well as changes of density as a function of fuel tempera- ture. In the realization of these plans LPG producing companies, research and development teams as well as producers of automobile LPG systems are involved. Successful completion of research works and design works will result in elimination of scarce disadvantages of LPG as an engine fuel, preserving at the same time all its numerous advantages as an alternative fuel for the future -the new era source of energy.
