Nowadays, ceramic exhaust gas sensors are installed in quantities of millions in automotive exhaust gas systems. Almost any automobile being powered by a gasoline combustion engine is equipped with at least one zirconia exhaust gas oxygen sensor (l probe) for detection of the air-to-fuel ratio l. The first part of this short overview focuses on potentiometric as well as on amperometric zirconia...

This paper presents performance study of Peugeot MM540 diesel engine using biodiesel prepared from used cooking oil. Transesterification process is followed to produce bio diesel and is blended with diesel in different proportion of 22:78 and 24:76 by volume and named as blend B22 and B24 respectively. Engine was run at different loads (0, 15, 30, 35, and 40kg) with constant speed of 1000rpm se...

Nowadays, the Organic Rankine Cycle (ORC) system, which operates with organic fluids, is one of the leading technologies for “waste energy recovery”. It works as a conventional Rankine Cycle but, as mentioned, instead of steam/water, an organic fluid is used. This change allows it to convert low temperature heat into electric energy where required. Large numbers of studies have been carried out...

Traffic related sources are a significant contributor of particulate matter, particularly in urban environments and major cities. Traffic related particles can be distinguished into: exhaust traffic related particles, which are emitted as a result of incomplete fuel combustion and lubricant volatilization during the combustion procedure, and nonexhaust traffic related particles, which are eithe...

In recent years more and more focus has been placed on the environmental aspects of ships, because of the great attention to exhaust gas emissions from ships including CO2, a leading contributor to Green House Gasses (GHG) emissions, due to their negative effect on global warming. Maritime transport has clear environmental advantages: it expends relatively little energy and its infrastructure r...

Context: There is a need to determine if body exhaust suits which were initially used and recommended by Sir John Charnley has a role in minimizing bacterial shedding in the operating room. Evidence Acquisition: The English literature search conducted for relevant articles. 14 articles were relevant to the role of body exhaust system in total joint replacement. Results: There is controversial e...
