A Comprehensive Comparative Investigation of Compressed Natural Gas as an Alternative Fuel in a Bi-Fuel Spark Ignition Engine
Authors
Abstract:
Nowadays, increased attention has been focused on internal combustion engine fuels. Regarding environmental effects of internal combustion engines particularly as sources of pollution and depletion of fossil fuels, compressed natural gas has been introduced as an alternative to gasoline and diesel fuels in many applications. A high research octane number which allows combustion at higher compression ratios without knocking phenomenon and with good emission characteristics of unburned hydrocarbons and carbon monoxide are major benefits of compressed natural gas as an engine fuel. In this paper, natural gas as an alternative fuel in a spark ignition engine, has been considered. Engine performance and exhaust emissions have been experimentally studied for both natural gas and gasoline fuels in a wide range of engine operating conditions.

Temperature is one of the effective parameters in erosion of spark plug electrodes. In this research, temperature of spark plug was measured in engine's different operation conditions with two types of fuels: compressed natural gas and gasoline. Test results showed that, temperature of center electrode is lower than ground electrode and maximum difference between them is 110ºC that occurs at...

The energy issue in transportation for the next 20 years is not one of adequate supply but rather it is a combination of overdependence on imported petroleum and of managing a transition to economically, strategically and environmentally desirable energy sources. More than a quarter of all energy consumption in the United States is attributable to transportation, as is nearly two-thirds of all ...
full textAn Experimental Investigation of Spark Ignition Engine Fueled with Ethanol/Iso-octane and Methanol/Iso-octane Fuel Blends
Alcohols have been used as a fuel for engines since 19th century. Among the various alcohols, ethanol and methanol are known as the most suited renewable, bio-based and ecofriendly fuel for spark-ignition (SI) engines. The most attractive properties of ethanol and methanol as an SI engine fuel are that it can be produced from renewable energy sources such as sugar, cane, cassava, many types ...
