Abstract Particulate emissions from diesel engines are a matter of public concern and continued industrial development. For an internal combustion engine, particles may originate either the after treatment box or crankcase ventilation system. This paper quantifies discusses particle sources within system medium-duty 4-cylinder heavy-duty 6-cylinder engine their dependence on oil parameters visc...

Engine oils are widely used for lubrication purposes in automobile and related industries. Viscosity Index (VI) improver has found its largest commercial applications as additives to engine oils. Examples are power steering fluid, aircraft piston engine oils, modern internal-combustion engines, turbine engine oils (stationary and aircraft), and industrial gear oils. Viscosity Index improvers ar...

In the literature, there are several empirical models to estimate the higher heating values of vegetable oils and biodiesel fuels. In this study, five of these models found in the literature were used to estimate the higher heating value of waste frying oils. When some models are used to estimate HHVs of waste frying oils, the relative errors were found up to 5% compared to the values obtained ...

In this study, the conventional acid-clay method was used to evaluate its potential for recycling waste crankcase lubricating oil (WCLO). The results showed that effective in re-refining WCLO and returning a quality comparable oils produced from fresh lube stocks. This has been reported account around 90% of global treatment is considered be an inexpensive process. revealed improved viscosity a...

Waste cooking oil (WCO) is being generated large scale all over the world; hence it has devised serious problems of its waste management. Organised collection of WCO <span style="font-size: 9pt; color: #...

There is considerable concern over the increasing demand on our limited supply fossil fuel and as a result initiatives are being considered to extend the use of such fossil fuels. In addition there is international concern regarding the associated pollution levels and it is these collective concerns that have increased the demand for alternative fuels to be used in internal combustion engines. ...

Abstract Waste cooking oil (WCO) is a promising feedstock for producing biodiesel, which plays significant role in waste resource reusing and renewable energy production. It known that cost the main factor restricting large-scale production of biodiesel. Therefore, Life Cycle Cost (LCC) method was used to analyze economic feasibility biodiesel process from WCO. Our results show 1 ?t WCO 6291.56...

This work intends to capitalize waste transformer oil (WTO) as a renewable source of fuel in a diesel engine, given the cost of fuel being used is reduced when using waste products. Previously, despite its higher viscosity, WTO is used as such or in blends with diesel in a diesel engine. However, in the current study, efforts are taken to chemically treat WTO so as to bring down its viscosity a...
