چکیده
A methodological method based on the use of theory preferred numbers has been proposed in order to improve most important parameters working bodies noise mufflers. As a result many years scientific research, authors have established previously unknown theoretical relationship between main series numbers, golden ratio and Fibonacci numbers. new direction development number considered paper, its classification compiled, including geometric containing basic using sequence. New formulas obtained determine denominators progressions for area circle. Determining circle formula allows get more accurate values. determining circumference also derived. The designs perforated partitions developed, which laws are used. you is obtained. regularities calculated substantiation structural dimensions mufflers given mathematical model partition allow obtain muffler design that lowest possible aerodynamic resistance with maximum reduction level exhaust gases from internal combustion engines. An innovative reciprocating engines improved hydraulic acoustic characteristics paper. applies any technical device.

15 صفحه اولTransient combustion control of internal combustion engines
This thesis addresses the problem of combustion control for automotive engines. A method is proposed to complement existing controllers, which use lookup tables based on steady-state operation. During transients, the new control method adjusts fast control variables (ignition or injection time) to compensate for deviations in the cylinder initial conditions from their optimal values due to the ...
متن کاملEthanol Internal Combustion Engines
Ethanol Internal Combustion Engines HIGHLIGHTS PROCESS AND TECHNOLOGY STATUS – The use of biofuels (e.g. bio-ethanol and biodiesel) in the transport sector can save significant amounts of fossil fuels and greenhouse gas (GHG) emissions. Internal combustion engines (ICEs) can run on bio-ethanol manufactured from biomass or waste through biochemical processes. Agricultural feedstock such as sugar...
