Research ArticleOpen accessIn the keywordsDiesel Engine Convert to Port Injection CNG Engine Using Gaseous Injector Nozzle Multi Holes Geometries Improvement: A ReviewSemin, Abdul Rahim Ismail, Rosli Abu BakarThe objective of this study was to review the previous research in the development of gaseous fuel injector for port injection CNG engine converted from diesel engine. Problem statement: The regular development of internal combustion engines change direction to answer the two most important problems determining the development trends of engines technology and in particular, their combustion systems. They were … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Apr 2009 · 8,631 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Investigation of Compressed Natural Gas Engine for Nitrogen Oxides ReductionP. M. Diaz, B. Durga PrasadProblem statement: This study describes the use of Reformer Gas (RG) to alter NOx emission in a CNG-fueled HCCI engine. Comparison with diesel, natural gas has a very high octane number (≈120) and high auto-ignition temperature (≈600°C). Composed mostly of methane, natural gas is the only common fuel to manifest relatively pure, single-stage combustion. Other fuels have stronger low-temperature reaction … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 15 May 2012 · 7,298 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExperimental and Skeletal Kinetic Model Study of Compressed Natural Gas Fueled Homogeneous Charge Compression Ignition EngineP. M. Diaz, B. Durga Prasad, D.S. Manoj Abraham, K. PalaniKumarProblem statement: In homogeneous charge compression ignition engines fuel oxidation chemistry determines the auto-ignition timing, heat release, reaction intermediates and the ultimate products of combustion. To shorten development time and to understand combustion processes, the use of simulation is increasing. Approach: A model that correctly simulates fuel oxidation at these conditions would be a useful design tool. Detailed models of … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 22 Mar 2012 · 7,255 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGreen Engines Development Using Compressed Natural Gas as an Alternative Fuel: A ReviewSemin, R. A. Bakar, A. R. IsmailProblem statement: The Compressed Natural Gas (CNG) is a gaseous form of natural gas, it have been recognized as one of the promising alternative fuel due to its substantial benefits compared to gasoline and diesel. Natural gas is produced from gas wells or tied in with crude oil production. Approach: Natural gas is promising alternative fuel to meet strict engine … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,167 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Technical Review of Compressed Natural Gas as an Alternative Fuel for Internal Combustion EnginesSemin, Rosli Abu BakarNatural gas is promising alternative fuel to meet strict engine emission regulations in many countries. Compressed natural gas (CNG) has long been used in stationary engines, but the application of CNG as a transport engines fuel has been considerably advanced over the last decade by the development of lightweight high-pressure storage cylinders. Engine conversion technology is well established and suitable … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 17,465 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Performance of Direct Injection Diesel Engines Fueled Using Compressed Natural Gas and Diesel Fuel Based on GT-POWER SimulationSemin, Abdul R. Ismail, Rosli A. BakarThe paper is investigated the application of compressed natural gas (CNG) as an alternative fuel and its performance effect in the diesel engines using GT-POWER computational simulation. The CNG as an alternative fuel for four stroke diesel engine modeling was developed from the real diesel engine using GT-POWER computational model with measure all of engine components size. The computational model … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,313 accessesView PDF Cite
