Alcoholic fuels have recently come to light as a sustainable source for powering today’s vehicles. Various studies investigated the effects of alcoholic on engine efficiency and emission characteristics. However, scarce literature is available their lubricant. Therefore, propanol-gasoline fuel mixtures, with concentrations 9% (P9) 18% (P18) propanol, were made compare characteristics lubricatin...

Water is one of the most significant destructive contaminations to lubricants which in turn lead to more power consumption and early damage to rotating machines. This study explores the effect of water contents in gearbox lube oil on the responses of electrical supply parameters. A two stage gearbox based mechanical transmission system driven by a sensorless variable speed drive (VSD) is utilis...

The protection of the environment and pollution control are issues paramount importance. Researchers today engrossed in mitigating harmful impacts petroleum waste on environment. Lubricating oils, which essential for smooth operation engines, often disposed improperly after completing their life. In experimental work presented this paper, deteriorated engine oil was regenerated using acid treat...

Air quality can be affected by merchant ships, so it is important to regulate emissions that are produced, as well use energy efficiently. In this sense, the cleanliness of oil used in lubrication essential achieve a better and reduce losses marine engines. For that, vital carry out good maintenance strategies. Therefore, develop techniques allow condition monitoring during engine operation. or...
