The limited fossil fuel resources along with the increased public concerns about pollution levels have increased the need for alternative fuels for use in internal combustion engines. This study is to investigate the variation of the engine performance and exhaust emissions of a spark ignition engine. A spark ignition engine running with gasoline and gasoline blended E5, E10 and E20. Effects of...

The objective of this work is tomake an experimental investigation onchemical feasibility of karanja seed oilby modified the fuel using karanja methyl ester(biodiesel)blends withmineral diesel. This experimentation evaluatethe performance and emission characteristicsof 4stroke, single cylinder, DI diesel enginetest rig. The karanja biodiesel blended withdiesel in various proportions like 10%,20...

Philip Martin....................................9 Any game works better when the rules are enforced consis­ tently, whether it is the Superbowl or Monopoly around the kitchen table. If the referee is indecisive, then the players are uncertain about how to play and the game degenerates. Transportation fuel markets in the United States currently resemble a game with inconsistently enforced rules...

The purpose of this paper is to provide an expected cost comparison for operating a transit-bus fleet on three different alternative fuels-biodiesel, compressed natural gas (CNG), and methanol. Petroleum diesel is the base fuel. Infrastructure, refueling, and maintenance costs are all part of running an urban transit bus. Additional expenditures would be needed to change fuel storage and delive...

The transport systems are dependent on the fossil fuels especially liquid fuels and these fuels are depleting at much faster rate than production. The consumption of fossil fuels is very unstable and directly affects the economy of our country as we are importing it from other nations so this factor has urged us to find other alternatives to prolong the usage of petroleum. Thus, by using bio-fu...

In order to clamp down on the illegal use of fishing boat fuel A (FBFA) and to reduce exhaust emissions in Taiwan, the residue from a desulfurization unit (RDS) and pyrolysis fuel oil (PFO) were added into FBFA with the ratio of 0.5% to form two new blended fuels (RDS0.5 and PFO0.5). The appearances of fuels from dark to light are RDS0.5, PFO0.5, and FBFA. The two new fuels have higher viscosit...

The impact on the usage of commercial fuels such as gasoline in automobile vehicles is an alarm in terms of health effects as it emits higher level of carbon dioxide to the atmosphere. In addition, the need and demand for Gasoline products are in the increasing trend because of more number of vehicles which are on road and Governments plan to increase the cost of fuel. As slowly the scarcity of...

methanol as a biofuel is an environmental friendly substitute to pure diesel and can be obtained from biomasses. use of biofuels such as methanol for combustion process is associated with positive environmental impacts. using pure methanol or blended with diesel fuel in automotive has been proposed by researchers. in this paper, methanol was injected into combustion chamber of a ism 370 hd dies...

This paper provides a comprehensive review of the technical feasibility of DME-Diesel blend as an alternative fuel for compression-ignition engines for automotive applications. DME is a synthetic fuel produced by the conversion of various feedstocks such as natural gas, coal, oil residues and bio-mass. The compatible properties such as high cetane number and low auto-ignition temperature with s...
