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 ...

This research based on the mineral base oil formulated in different additives for Automotive engines. In this experiment, performance of two groups are investigated, one which is Group-1 while other Group-II oil. Different products prepared automobile like Motorcycle, CNG Car and Diesel engine with required additives. Then, samples were used respective vehicles it observed that viscosity at 100...

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 ...

Nox estimation in diesel engines is an up-to-date problem but still some issues need to be solved. Raw sensor signals are not fast enough for real-time use while control-oriented models suffer from drift and aging. A control-oriented gray box model based on engine maps and calibrated off-line is used as benchmark model for Nox estimation. Calibration effort is important and engine data-dependen...

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...

This paper presents the design, applications, and performance of the miniature fiber optic-based cylinder pressure sensor which has targeted advanced engine controls requiring high accuracy pressure information. Three types of sensor packages are described currently utilized in prototype closed loop control systems for diesel, gasoline, and dual fuel engines: glow plug with the heater-mounted s...

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...
