In this paper, the use of gasoline combinations with ethanol and nano oxide particles has been studied in gasoline-based SI EF7 engines. The mixtures are prepared in five emulsions of gasoline with 10% ethanol, gasoline with 10% ethanol and 10ppm nano Mn2O3, gasoline with  10% ethanol and 20ppm nano Mn2O3, gasoline with 10% ethanol and 10ppm nano Co<s...

One of the major drawbacks of IC engines is low efficiency and pollution resulting from incomplete combustion. In order to improve the emission properties and performance an oxygenated additive MTBE (Methyl tertiary butyl ether), is blended with gasoline. A four cylinder, 1817 cc engine was used for analysing both emission and performance characteristics. Tests were carried out with 100% pure g...

The author describes the controversy about the use of tetraethyl lead (TEL) as a gasoline additive. Early warnings were ignored by industry, and as leaded gasoline became more profitable, scientists willing to support industry were financed as guardians of the scientific criteria for lead's health impacts. Controversy erupted in 1924 after refinery accidents left workers dying from violent insa...

this is the first report about adverse inhibitory effect of v-guard and e-guard gasoline additives against soil beneficial streptomyces. v-guard and e-guard gasoline additives are anti valve seat recession agents used in unleaded gas for old car engines in iran. they contaminate soil and groundwater by fuel leaks and spills. streptomyces are of the major contributors to the biological buffering...

The evaluation of the impact of an increase in gasoline tax on demand relies crucially on the estimate of the price elasticity. This paper presents an extended application of the Partially Linear Additive Model (PLAM) to the analysis of gasoline demand using a panel of US households, focusing mainly on the estimation of the price elasticity. Methodologically, we propose a root-n consistent esti...

With the way cleared for increased use of the fuel additive methylcyclopentadienyl manganese tricarbonyl (MMT) in the United States, the issue of possible public health impacts associated with this additive has gained greater attention. In assessing potential health risks of particulate Mn emitted from the combustion of MMT in gasoline, the U.S. Environmental Protection Agency not only consider...

In this study, effects of adding butene, homopolymer to gasoline on the performance a four-stroke spark ignition (SI) engine and pollutant emissions have been investigated. This additive increases octane number gasoline. research, was combined with non-leaded Also, in addition fuel changes use additives, plugs were replaced three types used for study. These include single electrode plug, dual p...

This review attempts to provide an overview of the interconnected industrial changes associated with compliance with the exhaust emission standards of the Clean Air Act of 1970. To understand the complex nature of air pollution problems, Federal legislation, and compliance with this legislation requires an understanding of automotive technology, petroleum refining, atmospheric chemistry and phy...

Methyl tert-butyl ether (MTBE) was originally introduced as an additive to increase octane number into gasoline in the 1970s. Its use was primarily as an octane enhancer to replace lead in gasoline. Later on, it was also used as an oxygenate, up to 15% v/v, to accomplish a cleaner burning fuel with reduced emissions of carbon monoxide and hydrocarbons. The problem with MTBE is that it has cause...

Benzene is used as an additive into gasoline to increase octane rating and prevent engine knocking. Being a toxic air pollutant known to have carcinogenic effects, knowledge of its concentration can be of aid in the assessment of possible health hazards to persons handling and using gasoline. The U.S. Federal Clean Air Act and the European Community specifications mandate a level of benzene in ...
