The effect of biodiesel composition on engine emissions from a DDC series 60 diesel engine
free download

Summary The National Renewable Energy Laboratory (NREL) is conducting an investigation of various biodiesel fuels produced from waste oils. As a part of this study, data on emissions on the Environmental Protection Agency (EPA) heavy-duty transient cycle

The application of availability and energy balances to a diesel engine
free download

The maximum power that can be extracted from an engine operating at a given condition was determined by means of analyses based on the first and second laws of thermodynamics. These analyses were applied to a heavy-duty single-cylinder

Experimental studies on the combustion and emission characteristics of a diesel engine fuelled with used cooking oil methyl ester and its diesel blends
free download

Transesterified vegetable oils (biodiesel) are promising alternative fuel for diesel engines. Used vegetable oils are disposed from restaurants in large quantities. But higher viscosity restricts their direct use in diesel engines. In this study, used cooking oil was dehydrated and
