ÖzDizel motorlar, sağladıkları yakıt ekonomisi ve yüksek termal verimleriyle günümüzde en çok tercih edilen motor tipidir. Ancak sıkıştırma ateşlemeli motorlarda yüksek sıkıştırma oranından dolayı meydana gelen ses dizel motorların en önemli dezavantajlarındandır. Yakıtın yanması sırasında meydana gelen ses hem yolcuların hem de sürücünün yolculuk konforunu azalmasına yol açmaktadır. Biyodizel, bitkisel ve hayvansal yağlardan elde edilebilen dizel yakıta alternatif yenilenebilir enerji kaynağıdır ve mevcut dizel motorlarda değişiklik yapmadan kullanılabilir.Bu çalışmada, pamuk yağı esterinin dizel motorlarda kullanımının motorlarda ses seviyesine olan etkileri deneysel olarak incelenmiştir. Yakıt olarak PB20 ve PB100 kullanıldığında test motoru tarafından üretilen ses seviyelerinin dB(A), dB(C) ve dB(Z) cinsinden dizel yakıtla karşılaştırıldığında azaldığı gözlemlenmiştir.Anahtar Kelimeler: Biyodizel, Desibel, Pamuk yap metil esteri, Ses seviyesi Investigation of Effects of Cotton Oil Biodiesel on Engine Noise Level AbstractDiesel engines are the most preferred engine type today with their fuel economy and high thermal efficiency. However, the noise coming from compression ignition engines due to the high compression ratio, is a major disadvantage of diesel engines. The noise created during combustion of the fuel leads to a decrease in the riding comfort of both the passenger and the driver. Biodiesel is an alternative renewable energy source for diesel fuel that can be obtained from vegetable and animal oils and can be used without modification in existing diesel engines.In this study, the effect of the use of cottonseed ester on diesel engines in engines was investigated experimentally. It has been observed that when using PB20 and PB100 as fuel, the sound levels produced by the test motor are reduced when compared to diesel in dB (A), dB (C) and dB (Z).

“…Most of the studies of the effect of the water emulsion fuel in diesel engine were performed at limited operating conditions [27]; therefore, further experimental studies are required for a comprehensive understanding of emulsion fuel at a variety of engine speeds and loads [14], and increasing the energy content of the emulsion fuel is essential to maintain the required engine power.Engine vibration performance is an important factor that needs to be considered with any proposed alternative fuel for a diesel engine, and only few researchers have tested and reported the alternative fuel effect on engine vibration. As an example, an experimental work was conducted to study the noise and vibration characteristics of diesel engine fuelled with sunflower, canola, and corn biodiesel blends at different percentages of volume ratio and H 2 injected through the inlet manifold at different flow rates [28]. UludamarYıldızhan [28] found that biodiesel blends reduce the vibration of the engine block.…”

The Influence of Emulsified Water Fuel Containing Fresh Water Microalgae on Diesel Engine Performance, Combustion, Vibration and Emission

et al. 2019

Microalgae is considered as an excellent potential renewable source of fuel in many forms including powder or slurry. A high percentage of emulsified water in the fuel is reported to reduce diesel engines’ emissions such as NOx, but that will compromise the engine output power. Using microalgae powder as an additive to enhance the emulsified water fuel heating value is the main objective of this work. Diesel engine combustion, vibration, performance and emissions were evaluated for pure cottonseed biodiesel (CS-B100), emulsified water 20% (vol.) in cottonseed biodiesel (CSB-E20) and emulsified water 20% (vol.) containing Fresh Water Microalgae Chlorella Vulgaris (FWM-CV) in cottonseed biodiesel (CSB-ME20). The emulsified water fuels showed a reduction in in-cylinder pressure, vibration, brake power, torque, exhaust gas temperature, CO2 and NOx, while BSFC and O2 were higher than the pure biodiesel (CS-B100). CSB-ME20 produced higher power and torque than CSB-E20 due to the presence of microalgae in the fuel that increased the energy content of the fuel.

In diesel engines, the most important parameter affecting the combustion performance is the injection advance. Since the injection advance directly affects the combustion quality, it also directly affects the outputs, such as ignition delay, in‐cylinder pressure, fuel consumption, and emission values. Therefore, setting the advance angle correctly is exceedingly significant for the optimum operation of the engine in all conditions. In this study, a single‐cylinder diesel engine with a mechanical fuel system was converted to a common rail fuel system by revising its fuel system. Experiments were carried out with the converted engine at a constant speed (1850 rpm), at different loads (3–4.5–6–7.5–9 Nm), and at different advance angles (10, 12, 14, 16, 18°). In the experiments, engine performance and emission (exhaust, vibration, noise) data were examined. When the cylinder pressure data is evaluated, the maximum in‐cylinder pressure approaches the top dead point in parallel with the increase in the advance angle. Specific fuel consumption occurred at a minimum advance angle of 10° under all load conditions. In exhaust emissions, minimum values at 10° advance angle were obtained for all emissions except for oxygen emissions. Vibration emissions were reduced by 6% at a 10° advancing angle compared to 18° advancing angle at 3 Nm load. It was determined that noise emissions decreased by 1.76% in the same experimental parameters. When all data are evaluated, the optimum advance angle for the revised fuel system has been determined as 10°.
