HCCI engine concept combines aspects of SI and Diesel engines by compression igniting a pre-mixture of fuel and air.
No flame propagation or mixing controlled combustion – global auto-ignition ofthe charge .
Can use uniformly ultra-lean mixtures, giving low peak combustion temperatures, near zero NOx emissions.
Auto-ignition is said to occur simultaneously at many locations, ca
the material or substance never disappear and travel in system of economy linking to environment. The materials are put into input, produce output and externalities through resource-consuming process. It may be expressed with a formula like as following.
Total amount of input = output + externalities
It indicates that thetotal amount of something as a resource we use in our activities is not
The first stage isthe coal gasification process as mentioned above. The second stage takes the cleaned gas and burns it in a conventional gas turbine to produce electrical energy, andthe hot exhaust gas is recovered and used to boil water, creating steam for a steam turbine which also produces electrical energy. In typical plants, about 65% ofthe electrical energy is produced bythe gas turbin
and its compounds, primarily ammonium nitrate and other ammonium salts, replenish nitrogen in depleted soils. This greatly increases yields of agricultural crops, especially those that cannot obtain nitrogen from the atmosphere. The ammonia is converted to nitric acid, an essential ingredient in explosives, via the Ostwald-Bauer process invented by German chemist Wilhelm Ostwald (1853-1932) in 19
the synergies between being a good corporate citizen and economic success.
Profit
"Profit" isthe economic value created bythe organization after deducting the cost of all inputs, including the cost ofthe capital tied up. It therefore differs from traditional accounting definitions of profit.
In the original concept, within a sustainability framework,
the "profit" aspect needs to
