The rapid depletion in world petroleum reserves and uncertainty in petroleum supply due to political and economical reasons, as well as, the sharp escalations in the petroleum prices have stimulated the search for alternatives to petroleum fuels. The situation is very grave in developing countries like India which imports 70% of the required fuel, spending 30% of her total foreign exchange earn...

Airborne particulate pollutants, such as diesel exhaust particles, are thought to exacerbate lung and cardiovascular diseases through induction of oxidative stress. Sulforaphane, derived from cruciferous vegetables, is the most potent known inducer of phase II enzymes involved in the detoxification of xenobiotics. We postulated that sulforaphane may be able to ameliorate the adverse effects of ...

With modernization and increase in the number of automobiles worldwide, the consumption of diesel and gasoline has enormously increased. In this experiment tri fuel concept was used according to that diesel and turpentine different proportion bled introduced in diesel engine and acetylene entre in the diesel engine through intake manifold in the diesel engine. Among the many process parameters,...

Biodiesel, the methyl ester of vegetable oil is a renewable, low environmental impact and potential as a green alternative fuel for diesel engine. High oil prices and growing concerns over climate change are driving investment and innovation in the biofuels sector as countries and industry increasingly look towards renewable bioenergy to replace fossil fuels. This study examines fuel properties...

This work was designed to determine the effect of poultry droppings on diesel contaminated soil and evaluate its physiochemical properties. In this study, different ratios of diesel contaminated soil and poultry droppings have been used as raw materials. The mixture of diesel contaminated soil and poultry droppings were allowed to composting process for 40 days. The physicochemical parameters l...

Results of experimental investigations of using a coil-shaped injector for reducing NOx emissions from a diesel engine are presented. The study involved the effects of coil length and its mixing effectiveness and the development of the injector system for after treatment of diesel exhausts. Results indicate that the coil-shaped injector system with the ratios of length, pitch and wire diameter ...

Introduction The present day oil crisis and need for more fuel economy has driven the demand for diesel powered automobiles. Diesel soot is one of the primary emissions of diesel combustion and accurate modeling of soot formation is a challenging area for combustion researchers. The soot formation in diesel engine combustion has been previously modeled using a twostep phenomenological model whi...

This study was set out to characterize particulate emissions from transportation diesel engine in terms of heavy metals. The exhaust particulates from Mahindra DI engine were collected and analyzed at four different engine operating conditions namely idling, 40%, 70% and full load. It was found that as the load increases from idling to full load, the heavy metal content in particulates graduall...

Water-in-diesel emulsions are fuels for regular diesel engines. The advantages of an emulsion fuel are reductions in the emissions of nitrogen oxides and particulate matters, which are both health hazardous, and reduction in fuel consumption due to better burning efficiency. An important aspect is that diesel emulsions can be used without engine modifications. This review presents the influence...
