The present study aims to investigate the relation between exposure to low-dose benzene and the occurrence of oxidative DNA damage in gasoline station workers, as well as the possible role of interfering or confounding factors. Urine levels of 8-OHdG were evaluated by a competitive immunoassay in a group of 80 men, employed in gasoline stations located in East Sicily and compared with a control...

A recent animal experiment suggests that gasoline exposure may be a cause of human kidney cancer. This is a literature review to see whether there is any epidemiologic support for these animal findings. Trends and geographic patterns in gasoline consumption and kidney cancer mortality are moderately supportive of a relationship, although this cannot be considered important evidence for a causal...

IC engines are considered as major contributors to the deterioration of the environment, therefore there is an increasing demand to go for alternative fuels for both SI and CI engine so as to maintain the ecological balance as well as reduce dependency on petroleum and socio economic aspects. The gaseous fuel such as LPG has been widely used throughout the world in SI engines as it impacts gree...

The phase equilibria, engine performance and gas emissions of gasoline-ethanol-water blends with pyridine isobutanol added for increased water tolerance, were investigated. It was observed that addition produced slightly higher ratios ethanol in the stable fuel blend when compared to isobutanol, ratio additive amount. Engine performances combustion characteristics measured a single cylinder, fo...

In this study; a four-stroke, air-cooled, spark-ignition engine was used. It’s aimed to improve the performance and emissions by renewing existing ignition fuel system of in way that can be controlled via computer. Classical modified with an electronic computer-controlled established using injector instead carburetor. Gasoline bioethanol fuels were compared original updated version conducting v...

This article analyzes the influence of the ignition retardation on the fuel consumption, the cumulative tailpipe hydrocarbon emissions, and the temperature inside the three-way catalytic converter in a gasoline direct injection engine operated under idling conditions. A dedicated cylinder-individual, model-based, multivariable controller was used in experiments in order to isolate the effect of...

Using a portable emissions measurement system, 16 gasoline passenger cars were tested on a fixed route consisting of different types of roads in Macao and the data were normalized with the vehicle-specific power bin method. The normalized HC, CO and NOX emission levels of the seven passenger car samples with model year older than 2000 were 3.19 ± 5.04, 14.59 ± 22.88, 2.57 ± 2.12 g/km, respectiv...

duction than is economically efficient. If ethanol is not economically competitive with gasoline, then subsidies distort the market by steering investment away from economically attractive gasoline and toward economically unattractive ethanol. Consumer well-being and overall economic efficiency suffer as a consequence. Support of ethanol subsidies and consumption mandates offer a mix of argumen...

In the present investigation, behavior of fuel consumption was studied due to high cost gasoline and its price increase in Ecuador recent years, for which reason different mixtures have been obtain lower consumption. The optimum mixture rate a T18SED e-tec II engine, Multiport Electronic Fuel Injection System (MPFI) between extra gasoline, super ethanol obtained on two urban roads city Quito (E...
