“…In diesel engines, knocking mainly occurs due to (i) high ignition delay (i.e., long time gap between the fuel injection and combustion); and (ii) sudden impacts exerted on the cylinder head during opening-closure, imposed by large valve clearance. In a related effort, Taghizadeh-Alisaraei et al [60] studied the correlation between biodiesel concentration and combustion, vibration, and knocking, in single-and six-cylinder diesel engines. Six biodiesel-diesel fuel blends were prepared using waste cooking oil, according to ASTM D6751-09 standard: D100 (pure petrodiesel), B20 (20% biodiesel + 80% diesel), B40, B60, B80, and B100 (pure biodiesel).…”

Internal combustion engines (ICEs) are the primary source of power generation in today’s driving vehicles. They convert the chemical energy of the fuel into the mechanical energy which is used to drive the vehicle. In this process of energy conversion, several parameters cause the engine to vibrate, which significantly deteriorate the efficiency and service life of the engine. The present study aims to gather all the recent works conducted to reduce and isolate engine vibration, before transmitting to other vehicle parts such as drive shafts and chassis. For this purpose, a background history of the ICEs, as well as the parameters associated with their vibration, will be introduced. The body of the paper is divided into three main parts: First, a brief summary of the vibration theory in fault detection of ICEs is provided. Then, vibration reduction using various mechanisms and engine modifications is reviewed. Next, the effect of using different biofuels and fuel additives, such as alcohols and hydrogen, is discussed. Finally, the paper ends with a conclusion, summarizing the most recent methods and approaches that studied the vibration and noise in the ICEs.

When the vibration of diesel engine structure is measured, the signal is composed of a very complex superposition of the contributions of different vibratory sources modified by their respective transmission paths. These sources originate from several internal phenomenons in the engine such as combustion pressure variation, unbalanced reciprocating and rotating parts. In a diesel engine, movement parts work in a specific order. Once the starting point is determined, occurrence of work order in different cycle phases can be determined. This could successfully use to identifying of impulses in complex vibration signal of a diesel engine. From the variation of features of those impulses, it is possible to determine the working condition of the engine. This can use to fault diagnosis of diesel engine, specially faults related to combustion process.

Environmental pollution due to fossil fuel combustion has made biodiesel a viable option. Biodiesel fuel has been widely used in land-based vehicle engines, but it is limited to marine sectors. This study investigated the cyclic variations effect of palm biodiesel to determine combustion stability in low compression marine diesel engine. The time series of peak pressure and indicated mean effective pressure is examined using statistical and continuous wavelet transformation methods. The results show that the cyclic variations on marine engine operated with palm biodiesel are better than diesel, as indicated by lower COVpmax and COVIMEP values, which are below 1.29% and 2.50% respectively. Increase the percentage of palm biodiesel in blends has gradually reduced the COVIMEP and the B30 palm biodiesel blend produces the minimum cyclic variations of IMEP with 1.91%. This finding was agreed with the wavelet spectrum results which revealed that the B30 palm biodiesel blend has the lowest IMEP frequency oscillation. The B30 palm biodiesel blend has produced the most stable combustion among the tested fuels.
