Abstract

The noise and vibration characteristics play a vital role in the effectiveness of engine operations and performance of internal combustion engines. Accumulation of the higher amplitude of both noise and vibration affects the comfort of the engine. So far most of the research done on the performance, combustion and emission characteristics only. The less importance is shown in the form engine vibration and sounds created by the engine operation. This paper presents and explores the importance and experimental results of noise and vibration by the compression ignition diesel engine with the fuels of diesel and microalgae biodiesel. The produced microalgae biodiesel blends were SMB10%, SMB20% and SMB30%. The experimental results were conducted at different engine loads varying across 25%, 50%, 75% and 100%. The inline, 4 cylinders, water cooled and naturally aspirated DI diesel engine was used as an experimental setup. From the comparative results between the diesel and microalgae biodiesel, it is found that the use of microalgae blended biodiesel reduced the noise and vibration. The higher the percentage of blends, the greater the reduction in sound and vibration will be. Apart from possessing the performance and emission qualities, the microalgae biodiesel blends proved to be the efficient fuel in reduced vibration and noise qualities too. In three directions, the vibrations were measured as lateral, longitudinal and vertical vibrations. The vibration in lateral direction was significantly reduced. Compelling the results, it is understood that use of the microalgae blends can be sustainable in the perspective of the engine wear and tear.

微藻生物柴油混合物如何影响直喷发动机的声学和振动特性:一项实验研究
噪声和振动特性对发动机运行的有效性和内燃机的性能起着至关重要的作用。噪声和振动的较高振幅的积累会影响发动机的舒适性。到目前为止,大多数的研究都只对性能、燃烧和排放特性进行了研究。不太重要的表现在发动机振动和发动机运行产生的声音的形式上。本文介绍并探讨了以柴油和微藻生物柴油为燃料的压燃式柴油机噪声和振动的重要性及其实验结果。生产的微藻生物柴油共混物分别为SMB10%、SMB20%和SMB30%。实验结果是在25%、50%、75%和100%的不同发动机负载下进行的。采用直列四缸水冷自然吸气直喷柴油机作为实验装置。从柴油和微藻生物柴油的比较结果来看,微藻混合生物柴油的使用降低了噪音和振动。混合物的百分比越高,声音和振动的降低就越大。微藻生物柴油混合物除了具有性能和排放质量外,还被证明是降低振动和噪音的有效燃料。在三个方向上,振动被测量为横向、纵向和垂直振动。横向振动明显减小。令人信服的结果是,从发动机磨损的角度来看,微藻混合物的使用是可持续的。
