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 a modern day world alternative source of energy are given importance due to gradual depletion of fossil fuels reserves vegetable oils can be used as an alternative to diesel in CI engines. The use of vegetable oils in CI engine results in low CO and HC emissions compared to conventional diesel fuel. The present study covers the various aspects of biodiesels fuel derived from cottonseed oil. ...

Existing diesel engines are under stringent emission regulation particularly of smoke and particulate matter in their exhaust. Compressed Natural Gas and Diesel dual fuel operation is regarded as one of the best ways to control emissions from diesel engines and simultaneously saving petroleum based diesel fuel. Dual fuel engine is a conventional diesel engine which burn either gaseous fuel or d...

Telecommunications industry requires efficient, reliable and cost-effective hybrid power system as alternative to the power supplied by diesel generator. This paper proposed an operational control algorithm that will be used to control and supervise the operations of PV/Wind-Diesel hybrid power generation system for GSM base station sites. The control algorithm was developed in such a way that ...

OBJECTIVE To investigate the comparative acute health effects associated with exposures to diesel and 75% biodiesel/25% diesel (B75) blend fuel emissions. METHODS We analyzed multiple health endpoints in 48 healthy adults before and after exposures to diesel and B75 emissions in an underground mine setting-lung function, lung and systemic inflammation, novel biomarkers of exposure, and oxidat...

Hexanol was added in ethanol – diesel fuel to prevent separation of ethanol from diesel in this study. The ethanol blend proportion can be increased upto 45% in volume by adding the Hexanol. Engine performance and emissions characteristics of the fuel blends were investigated on a diesel engine and compared with diesel fuel. Experimental results show smoke emission decreases significantly with ...

Diesel exhaust (DE) characteristic of pre-1988 engines is classified as a "probable" human carcinogen (Group 2A) by the International Agency for Research on Cancer (IARC), and the U.S. Environmental Protection Agency has classified DE as "likely to be carcinogenic to humans." These classifications were based on the large body of health effect studies conducted on DE over the past 30 or so years...

We introduce a syntax and semantics for an adaption of the Join Calculus to the Diesel programming language, entitled Join Diesel. We describe the design decisions and trade-offs made in integrating these concurrency primitives into the Diesel language. We also give a typechecking algorithm for the function calls and method declarations of Join Diesel and then prove its soundness.

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 then transesterified using an alkaline catalyst. The combustion, performance and emission characteristics of Used ...

A Cummins N14-410 diesel engine was operated on twelve fuels produced by blending methyl tailowate, methyl soyate and ethanol with No.2 diesel fuel. Engine incylinder pressure data were used to evaluate engine performance. Peak cylinder pressures for each fuel blend at all engine speeds were lower than peak pressure for diesel fuel with the exception of the 80 % diesel, 13 % methyl tallowate, a...
