This paper deals with highlighting the improvisations in the working of a two-wheeled four stroke internal combustion engines. The efficiency of these small engines were enhanced with increased power output just by increasing the number of fuel igniting element i.e. Spark Plug. Conventional engines employed a single spark plug in its engine for igniting the mixture of fuel and air. But to have ...

There is considerable interest in transport models that will permit the simulation of neutral particle transport through stochastic mixtures. Chord length sampling techniques that simulate particle transport through binary stochastic mixtures consisting of spheres randomly arranged in a matrix have been implemented in several Monte Carlo Codes [1-3]. Though the use of these methods is growing, ...

G lobal energy demand is projected to increase 50% or more by the year 2030, with coal remaining the primary fuel for developing countries. Because of the deleterious effects of fossil fuels and the uncertainties of future sources, the development of alternative renewable energy supplies such as hydrogen is critical. Hydrogen, the simplest and most abundant element, can be produced as a gas (H2...

The mixture formation prior to the ignition process plays as a key element in the diesel combustion. Parametric studies of mixture formation and ignition process in various injection parameter has received considerable attention in potential for reducing emissions. Purpose of this study is to clarify the effects of injection pressure on mixture formation and ignition especially during ignition ...

Combined power generation or cogeneration is a highly effective technology that produces heat and electricity in one device more efficiently than separate production. Overall effectiveness is growing by use of combined technologies of energy extraction, taking heat from flue gases and coolants of machines. Another problem is the dependence of such devices on fossil fuels as fuel. For the combus...

Reducing weight of vehicle components will contribute towards overall weight reduction of a vehicle, lower its energy consumption demand, therefore, will improve its fuel efficiency. Material resources will be saved too. The objective of this research is reduce weight of an existing steering knuckle component of a local car model by applying shape optimization technique. A finite element modeli...

This article presents an analysis of thermal state a fuel element the WCTC-LEU IVG.1M reactor implemented for case when matrix is separated from cladding along short side blade. Technology manufacture modernized core considers presence non-uniformity in microstructure. To evaluate how separations typical size affects mode operation, temperature fields cross-sections have been calculated. Thermo...

This paper reports oneand two-dimensional simulations of cavitating flows by the Space-Time Conservation Element and Solution Element (CE/SE) method. A continuum cavitation model based on specifying the speed of sound of two-phase flows is employed. The CE/SE method is a viable CFD method for flows at wide range of Mach numbers. The method is explicit and is suitable for time accurate simulatio...

Since fuel must be injected with appropriate pressure and time for accurate performance of diesel engines, then proper function of engine is influenced by accurate function of injector pump. At first total pump was designed by SolidWorks 2012 software. Then the total relationship of rotor, roller, internal cam ring, pole shoe and plunger in injector pump in MF285 tractor and their performance w...
