“…However, it can generally be observed that with an increase in butanol fraction, the ROHR peaks also increase from 13.1 J/°CA, 15.1 J/°CA and 15.5 J/°CA for GBu5, GBu10 and GBu15, respectively, compared with 16.9 J/°CA by G100. It was shown in the early studies [26,79,80] that ROHR tends to increase with increasing concentration of n-butanol, whereas other studies [23,30,32] showed an opposite outcome. In particular, Wallner et al [80] showed an increase in ROHR for the blended n-butanol with gasoline compared with neat gasoline.…”

“…Some researchers have also attempted to draw fine distinctions using different types of butanol isomers such as isobutanol-see, e.g., [20,32,[47][48][49][50][51][52]-and tert-butanol-see, e.g., [53]. The research to date has tended to focus on n-butanol, isobutanol and tertbutanol rather than 2-butanol.…”

“…Based on the reported study, the highest reduction of emissions was produced by E85% with 20% and 15% reduction for HC and (CO and NO x ), respectively. Sayin and Balki [32] analysed the effect of different compression ratios (9:1, 10:1 and 11:1) for different isobutanolgasoline blends (10%, 30% and 50%) in a single-cylinder four-stroke air-cooled gasoline engine. Throughout the experiment, it was reported that a higher compression ratio (11:1) capable of maintaining the emissions of HC and CO at a lower level, however, yielded higher CO 2 emissions.…”

In this study, performance and emission characteristics of a variable compression ratio (VCR) diesel engine fuelled with diesel fuel and diesel-biodiesel-alcohols blends have been evaluated in detail. The results of performance and emission characteristics of fuel blends were compared with low sulphur diesel fuel. Experimental study showed that biodiesel and alcohol addition to diesel fuels slightly affects the performance, combustion and emissions characteristics of the engine. The results showed that the increasing biodiesel ratio in the blend resulted in decrease of brake thermal efficiency and increment of specific fuel consumption (SFC). Furthermore, it was revealed that addition of alcohols and biodiesel fuel decreased carbon monoxide emission and increased NO x and carbon dioxide emissions.Keywords: Performance, Emission, Butanol, Ethanol, Biodiesel Dizel, Dizel-Biyodizel-Alkol Yakıt Karışımlı Sıkıştırma Oranı Değişen Bir Dizel Motorun Performans ve Emisyon Karakteristiklerinin Değerlendirilmesi ÖzetBu çalışmada, sıkıştırma oranı değiştirilebilir dizel ve dizel-biyodizel-alkol karışımları kullanılan bir dizel motorun performans ve emisyon özellikleri ayrıntılı olarak değerlendirilmiştir. Yakıt karışımlarının performans ve emisyon karakteristik sonuçları, düşük kükürtlü dizel yakıt ile karşılaştırılmıştır. Deneysel çalışma, dizel yakıtlara biyodizel ve alkol ilavesinin motor performansını, yanma ve emisyon özelliklerini çok az etkilediğini göstermiştir. Sonuçlar, karışımdaki biyodizel oranı artışının, ısıl verimde azalışa ve özgül yakıt tüketiminde (SFC) ise ait artışa neden olduğunu göstermiştir. Ayrıca, alkol ve biyodizel yakıt ilavesinin karbon monoksit emisyonunu azalttığını ve NO x ve karbon dioksit emisyonlarını ise arttırdığını ortaya çıkarmıştır.

“…It was found that increasing compression ratio resulted in a significant increase of the in-cylinder pressure and brake power, and a decrease in the fuel consumption, hence improved thermal efficiency. Sayin et al [10] experimented on a SI engine operated with gasoline and iso-butanol/gasoline blend fuel run at compression ratios of 9:1, 10:1 and 11:1. The results show that the increase of compression ratio led to better thermal efficiency and minimum fuel consumption.…”

The performance, emissions and combustion characteristics of a spark ignition engine at varying compression ratio and spark timing using two grades of gasoline in Saudi Arabian market, RON91 and RON95 have been presented on this paper. The tests were conducted using a single cylinder, four-stroke spark ignition research engine that operates with different RON fuel. The experiments were conducted at a wide-open throttle with an engine speed of 2500 rpm at stoichiometric conditions for three different compression ratios (9.5:1, 10:1, 10.5:1). At each compression ratio, the spark timing was varied till knocking is detected. The performance characteristics such as brake power, specific fuel consumption, thermal efficiency, in-cylinder pressure, rate of heat release, and exhaust emissions were analyzed. The data shows that the increasing of compression ratio and spark timing increased the brake power and decreased the brake fuel consumption for both type of fuels. Increasing compression ratio was more advantageous for RON95 due to the auto-ignition resistance event. The NO x emission was insignificantly decreasing as compression ratio increases with lower NO x emission from RON91. Compression ratio had considerable effect on CO emission for both fuels.
