“…Biodiesel is an environmentally friendly, renewable fuel which can be used in any compression ignition engine to substitute diesel fuel. Chemically, biodiesel contains a mixture of methyl esters with long-chain fatty acids, and is typically derived from nontoxic biological resources, such as vegetable oils [35][36][37][38][39], animal fats [40][41][42][43][44][45][46], or even cooking oils [47][48][49][50]. While many recent works analyzed the effects of biodiesel on the injection process, spray formation, and combustion [51][52][53][54][55][56], this section will emphasize the potential of different biofuel blends in reducing the noise and chemical pollutions of ICEs.…”

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.

“…3 The possibility to easily transform the used vegetable oil in valuable goods combined with the necessity to avoid its dispersion in the environment 4 and with its availability in very large amounts, 5 pushed many local industries to invest in WCOs processing. The most common utilizations of recycled WCO include the bio-lubricants production, 6,7,8,9 the employment as animal feed, 10,11 and the energy production (direct burning 12,13 or as fuel ingredient 14,15,16,17 ). In addition, some recent application of recycled WCOs involve the production of eco-friendly biodegradable solvents, 18 the use as additive for bio-asphalts and bio-concrete, 19,20 and its exploiting as non-aqueous gas sorbents devices.…”

Samples of sunflower Waste Cooking Oils (WCOs) subjected to several cycles of frying were treated with water under four different combinations of temperature and pH. The variation of the chemical composition of the oil samples was monitored through headspace Solid-Phase Microextraction (HS-SPME) coupled with gas-chromatographic technique (GC), 1H NMR spectroscopy and ESI+ mass spectrometry measurements. The possibility to modify the chemical composition of the recycled vegetable oil by tuning the water treatment parameters was exploited for the designing of a mini-plant for the production of bio-lubricants. A full description of the proposed prototype is also reported.

“…2 The main components of triglycerides are saturated and unsaturated fatty acids, which can be used as platform chemicals for the manufacturing of added-value products in various segments of industry. More common industrial applications of WCOs are related to energy production, by direct burning , 4,5 or for the synthesis of bio-fuels 6,7 Two additional non-negligible market segments of recycled WCOs are represented by the bio-lubricants, 8 and by the production of animal feed. 9 Many research papers, including review articles, have been reported on the above mentioned subjects during the last years.…”

The consideration toward Waste Cooking Oils (WCOs) is changing from hazardous waste to valuable raw material for industrial application. During the last five years some innovative processes based on the employment of recycled WCO have appeared in the literature. In the present review article, the most recent applications of recycled Waste Cooking Oil are reported and discussed. These include the production of bio-plasticizers, the application of chemicals derived from WCOs as energy vectors, and the use of WCOs as solvent for pollutant agents.
