Oil analysis is one of the main methods for monitoring the status of internal combustion engines and oils to ensure the lubricant's protective performance and engine health. This paper investigate oil condition monitoring in gasoline engine using oil dielectric coefficient measurement. At first capacitive sensor pectinate type is designed and manufactured that engine oil can pass through the se...

The environment is considered as man’s important asset that must be protected for his life support. Regrettably the situation is different where oil refinery and petrochemical plants operate. Environmental pollution in the form of emissions and effluent discharge in these area poses serious threat to the ecosystem particularly soil, often with undesirable effects. The study collected soil sampl...

Abstract Objective(s): Copper nano particles are added to ordinary engine oil as an additive to reduce friction and repair damaged surface under friction conditions. However, it is still unclear what environmental effects such a compound might have on conventional engine oils and its toxicity in different animal species has not been determined. The aim of this study is to investigate the ...

Objective(s): Iranian researchers have enriched conventional engine oil with nanoparticles at the Institute of Petroleum Research and hope that this product can replace conventional engine oil due to the improved effects of copper nanoparticles on oils. the purpose of this study was to investigate the pathological effect of engine oil enriched with copper nanoparticles on the rat.Methods:...

In order to reduce wear in gudgeon pin, bush and piston boss lubrication is done. Oil used in national engine species was 10W40 with dynamic viscosity 5.5 mPa.s at 140 °C (the working temperature). In order to complete investigation the oil film hydrodynamics analysis in small end of connecting rod, a real full model engine with four cylinders has been simulated by AVL EXCITE5.1 software. In...
