This paper represents the prospect of mustard oil as a renewable and alternative fuel. To cope up with present load-shedding situation and to reduce the dependency on imported fuel, Bangladesh government is encouraging the use of renewable energy sources. Since diesel engines have versatile uses including small irrigation pumping systems, and standby small electricity generators, use of diesel ...

  This paper presents a modeling study of a CNG Homogenous Charge Compression Ignition (HCCI) engine using single-zone and multi-zone combustion models. Authors' developed code could be able to predict engine combustion and performance parameters in closed part of the engine cycle. As detailed chemical kinetics is necessary to investigate combustion process in HCCI engines, therefore, GRI-m...

Portable generators are commonly used during electrical service interruptions that occur following large storms such as hurricanes. Nearly all portable generators use carbon based fuels and produce deadly carbon monoxide gas. Despite universal warnings to operate these generators outside only, the improper placement of generators makes these devices the leading cause of engine related carbon mo...

The paper presents a procedure for gas-dynamic analysis of processes in the air-gas channel of a small-sized two-stroke combustion engine. All steps are described. At the first stage a three-dimensional model of the interior space of the air-gas channel of a piston small-power engine was built; this model was split into nine different volumes according to the methodology of volumes partition fo...

This paper represents the mustard oil is a kind of renewable energy and alternative fuel of the future. In order to cope with the current situation of load shedding, and reduce dependence on imported fuels, the Bangladesh government to encourage the use of renewable energy. Because the diesel engine with multiple functions, including small pumping irrigation system and backup generators, diesel...

in this study, a numerical simulation using the cfd software, fluent, has been conducted to examine the effect of various shapes of the venturi component sections in order to find the optimum venturi specifications to increase the egr rate with minimum pressure loss at the part load operation range. the cfd results reveal that the venturi should be precisely optimized to introduce the required ...

Recently, many countries have paid substantial attention to power generation from biomass gasification, particularly through small-scale plants. A number of power plant models have been suggested and analyzed; however, certainly, desirable configurations have not been identified yet. Moreover, their performances are ordinarily difficult to compare, especially owing to the fact that working ...

A small 100 W displacer-type Stirling engine, Ecoboy-SCM81 has being developed by a committee of the Japan Society of Mechanical Engineers. The engine contains unique features, including an expansion cylinder which is heated by either combustion gas or direct solar energy. Also, a simple cooling system rejects heat from the working gas. A displacer piston has both heating and cooling inner tube...
