Harvester ants (Messor galla Forel) defied various control strategies. Two field experiments were conducted to evaluate the effects of Spent Engine-Oil and other nature-based materials on their emergence in Maiduguri, Borno State of Nigeria. The treatments evaluated are spot application of spent engine-oil and some natural materials in experiment 1 and individual and equal mixture of Pure Neem ...

various combustion characteristics and properties are studied while selecting a fuel for any engine. the choice of the engine and fuel are highly interrelated. vegetable oil is one obvious fuel particularly because their fuel properties are closer to diesel fuel. two important properties, the cetane number and the calorific value are similar to diesel. hence diesel engines can be operated on ve...

in this research, nano materials with tubular structures are added to sae 20w50 engine oil to study the rate of their effects on the properties of engine oil. multi-walled carbon nanotubes (mwcnts) and vanadium oxide nanotubes (vonts) has been used as two different additive materials, one of them is carbonic and the other is metallic oxides and their effect on  different parameters containing v...

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 th...

investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (lhr) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].the engine had different operating conditions...

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:...
