  • Second law analyses on oxy-fuel combustion of gaseous fuels

    The exergy losses in the adiabatic premixed oxy-fuel combustion are quantitatively analysed. The global exergy loss decreases with increasing equivalence ratio. The exergy loss of chemical reaction is comparable to that of internal thermal energy exchange for low equivalence ratio while that of mixing process is negligible. To keep similar thermodynamic characteristics of conventional combustion, ...

  • Analysing coloured smoke | Pearl or Quest?

    Coloured smoke consists of an aerosol of tiny particles which is combusted or vaporized. The particular pigment or dye of each colour affects the colour of the smoke. The mixture usually includes a cool-burning formula based on potassium chlorate oxidiser, dextrin or lactose as fuel. Then one or more dyes are introduced to account for around half of the mixture. A small amount of sodium ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • Energy and exergy analyses of a spark-ignition engine

    In this paper, the performance of an internal combustion engine is evaluated at the steady-state condition by application of energy and exergy analysis using the experimental test results. The energy and exergy balances are calculated at different engine speeds. The results show that the heat rejection of energy and exergy flow increases with increasing engine speed. The exergy efficiencies are ...

  • Analytical and experimental study on bending vibration of internal combustion engines shafting system based on wave equations

    This paper proposes a new analytical approach to study the bending vibration of N step shafting system. Changes of the shaft step properties under rotary condition are governed by two–dimensional wave equations. The source of the bending vibration is first analysed. Then strain and stress equations of the spinning shaft are established. After Hamilton principle is applied, a two–dimensional wave ...

  • Combustion, performance and emission analysis of diesel engine fuelled with methyl esters of Pongamia oil

    The methyl esters of vegetable oils, known as biodiesel are increasingly becoming popular because of their low environmental impact and potential as a green alternative fuel for diesel engine, and that they would not require significant modification of existing engine hardware. Methyl ester of Pongamia oil (PME) is derived through transesterification process. Experimental investigations have been ...

  • Effects of varying air-fuel ratio on the performance of a theoretical Diesel cycle

    This paper analyses the effects of varying air-fuel ratio on the performance of a theoretical Diesel cycle under a temperature restriction as maximum. Amount of heat addition at constant pressure is defined as a function of fuel's energy with utilising the combustion efficiency. The amount of released energy into the cylinder restricts the compression ratio. Relations between the combustion ...
