This article presents the results of research into causes wear piston pin mounted in bosses by means a hinge joint and connecting rod small end thermocompression bond. Changes geometry pin-top surface structure, which are caused mutual influence mating surfaces variable lubrication conditions, presented. The progress scuffing as result insufficient elements or oil film breaking is demonstrated....

Biomass derived fuels are preferred as alternative fuels for IC engine due to its abundant availability and renewable nature. In the present work, the complete replacement of diesel fuel with bio-fuels is studied, where the bio-fuels, namely, methyl ester of palm kernel oil and eucalyptus oil were chosen and used as fuel in the form of blends. Various proportions of palm kernel oil and eucalypt...

The study achieve to make an environmental impact assessment for a spent engine oil recycling plant in AL-Diwaniyah city – Iraq. has been carried out using Leopold matrix. studied deals with the bentonite clay as adsorbent material removing impurities from oil. waste of which discharged by- product without any minimal level remediation is harmful all components addition that, discharges air pol...

Contamination of soil / water resources by petroleum products poses severe threats to underground water and soil quality. In the present study biosurfactant producing bacterial cultures were used to degrade petrol engine oil under in situ conditions in the plant rhizosphere system. Two bacterial isolates used in this study were recovered from Haldia oil refinery sites and identified as Pseudomo...

This study discusses the performance and combustion characteristics of a direct injection (DI) diesel engine fueled with biodiesels such as waste (frying) palm oil methyl ester (WPOME) and canola oil methyl ester (COME). In order to determine the performance and combustion characteristics, the experiments were conducted at the constant engine speed mode (1500 rpm) under the full load condition ...

The paper by de Ree et al. mischaracterizes some key components of the reported association between exposure to aviation engine oil fumes and delayed, chronic neurological illness reported by exposed crewmembers. The authors are correct that airline crewmembers inhale oil fumes when the ventilation air that is supplied to the cabin and flight deck is contaminated with pyrolyzed oil. It is longr...

AIM Used oil is contaminated not only with heavy metals but also with polycyclic aromatic hydrocarbons (PAHs) that are insignificant in the unused oil. In our study we determined possible reproductive effects of used engine oil on male rats. MATERIAL AND METHODS Twenty eight male Wistar rats were used for the study. The rats had average weight of 181.5 ± 10 g, animal feeds and portable water ...
