“…However, in the later years it was found that MTBE had high solubility in water and did not degrade naturally. Therefore, the groundwater was contaminated in those areas where the underground gasoline tanks in the filling station were leaking (Donahue et al, 2002). Even in low concentrations, humans detected the foul odour and taste of MTBE in water.…”

Energy is the driver in the economic development of any country. It is expected that the developing countries like India will account for 25% hike in world-wide energy demand by 2040 due to the increase in the per capita income and rapid industrialization. Most of the developing countries do not have sufficient oil reserves and imports nearly all of their crude oil requirement. The perturbations in the crude oil price, sanctions on Iran and adverse environmental impacts from fossil fuel usage are some of the concern. Therefore, developing countries have started investing heavily in solar and wind power and are considering hydrogen as a future energy resource. Hydrogen is possibly the cleanest fuel and produces only water vapour upon combustion. However, to tap the potential of hydrogen as a fuel, an entirely new infrastructure will be needed for transporting, storing and dispensing it safely, which would be expensive. In the transportation sector, a liquid alternate to fossil fuels will be highly desirable as the existing infrastructure can be used with minor modifications. Amongst the possible liquid fuels, methanol is very promising. Methanol is a single carbon atom compound and can be produced from wide variety of sources such as natural gas, coal, and biomass. The properties of methanol are conducive for use in gasoline engines since it has high octane number and flame speed. Other possible uses of methanol are: as a cooking fuel in rural areas, and as a fuel for running the fuel cells. The present study reviews the limitations in the hydrogen economy and why moving towards methanol economy is more beneficial.

“…This legislation mandated dramatic reductions in automotive emissions, prompting automobile manufacturers to develop a catalytic converter to meet the requirements of the regulation. As a result, automobiles equipped with catalytic converters required unleaded gasoline to avoid poisoning the catalyst system by the tetraethyl lead [25]. Thus, methyl tert-butyl ether (MTBE) was added into gasoline at low amounts (1-3 vol percent) to replace tetraethyl lead as an octane booster.…”

“…While using methyl tert-butyl ether (MTBE) as an oxygenate addition may reduce pollutants released into the atmosphere due to complete combustion, its adverse effects on water quality have become a point of contention. According to a global market report, demand for methyl tert-butyl ether (MTBE) climbed progressively from 20.6 million tons in 1994 [27] to 21.0 million tons in 1999 and 22.0 million tons in 2002 [25,28]. However, due to MTBE's adverse environmental effects, ethyl tert-butyl ether (ETBE) has grown in popularity as a substitute oxygenate additive for gasoline.…”

Gasoline is a petroleum-derived liquid that is most typically used in internal combustion engines, especially those utilizing spark ignition. Gasoline is a hydrocarbon blend that contains sulfur, nitrogen, oxygen, and other metals. Olefins, aromatics, paraffin, and naphthenes are the four main components of gasoline. An octane number is a unit of measurement for the ignition quality or flammability of gasoline.It is frequently referred to as the research octane number (RON), and it is calculated using a ratio of isooctane to n-heptane. The octane number can be decreased by lengthening the hydrocarbon molecule chain and increasing by branching the carbon chain. Another method is to use an octane number increaser for gasoline as an addition. These are classified as oxygenate, ether, antiknock agent, nanoparticles, and aromatic compounds. Numerous studies have been conducted to establish the influence of additives in gasoline on engine performance metrics such as braking power, thermal brake efficiency, volumetric efficiency, fuel consumption efficiency, and their impact on the environment. This review article aims to assess and compare the effects of various gasoline additives on the performance and emission characteristics of ignition engines.
