The main objective of this study is to analyze the different ratio of emulsified fuels on the performance, emission and combustion characteristics of four stroke single cylinder kirloskar TV-I direct injection compression ignition engine and compared with diesel fuel under different engine loads with constant engine speed of 1500 rpm. Four kinds of test fuels were prepared namely 80% diesel, 10...

Many organizations interested in renewable, domestic energy have switched from petroleum diesel to biodiesel blends for use in transportation and heavy-duty equipment. Although considerable evidence exists on the negative health effects of petroleum diesel exhaust exposures in occupational settings, there has been little research examining biodiesel exposures. Working collaboratively with a loc...

To achieve energy saving and emission reduction for vehicle diesel engines, the organic Rankine cycle (ORC) was employed to recover waste heat from vehicle diesel engines, R245fa was used as ORC working fluid, and the resulting vehicle diesel engine-ORC combined system was presented. The variation law of engine exhaust energy rate under various operating conditions was obtained, and the running...

The paper presents introduction to the research on possible supplying ship diesel engines with mixtures of diesel oils and vegetable oils or their esters with accounting for ecological aspects – exhaust gas purity. Characteristics of vegetable oils and their esters are compared with those diesel oils. Consequences of their application to diesel engines, mainly for their working process and exha...

The results of an experimental work carried out to evaluate the effect of palm oil methyl esters, also known as palm oil diesel (POD) and its emulsions as alternative fuel on unmodified indirect injection diesel engine's wear and lube oil performance are presented in this paper. Half throttle engine with constant 2500 rpm setting was maintained throughout the wear debris and lube oil analysis s...

A novel geometry for enhancing the sensitivity of intensity modulated refractometric fiber optic sensor for detection of adulteration level in diesel by kerosene is proposed. In this multimode plastic optical fiber is uncladded for specific length and bent into S shape. This geometry is simulated and analyzed using Beam Propagation Method in Beam prop RSOFT software. When sensor is immersed in ...

There are at least three mechanisms by which alveolar macrophages play a critical role in protecting the lung from bacterial or viral infections: production of inflammatory cytokines that recruit and activate lung phagocytes, production of antimicrobial reactive oxidant species, and production of interferon (an antiviral agent). In this article we summarize data concerning the effect of exposur...

Rapid depletion of fossil fuels, increasing fossil-fuel price, carbon price, and the quest of low carbon fuel for cleaner environment – these are the reason researchers are looking for alternatives of fossil fuels. Renewable, non-flammable, biodegradable, and non-toxic are some reasons that are making biodiesel as a suitable candidate to replace fossil-fuel in near future. In recent years, in m...

This research work depends on enhancing the execution of the diesel engine when they utilized bio diesel oil as an optional fuel without real alteration of engine design. It is also required to grow non edible feed stocks in the waste or marginal land of Gujarat. Work goal is to recognize best suitable Bio-Diesel mix by keeping numerous parameters on it. Bio-Diesel mixes will be given credit sc...
