Green Engine : Seminar Report and PPT
Definition Green Engine
Everyday radios, newspapers, televisions and the internet warn us of energy exhaustion,
atmospheric pollution and hostile climatic conditions. After few hundred years
of industrial development, we are facing these global problems while at the same
time we maintain a high standard of living. The most important problem we are
faced with is whether we should continue "developing" or "die".
Coal, petroleum, natural gas, water and nuclear energy are the five main energy
sources that have played important roles and have been widely used by human beings.
The United Nations Energy Organization names all of them "elementary energies",
as well as "conventional energies". Electricity is merely a "second
energy" derived from these sources. At present, the energy consumed all over
the world almost completely relies on the supply of the five main energy sources.
The consumption of petroleum constitutes approximately 60 percent of energy used
from all sources, so it is the major consumer of energy.
Statistics show that, the daily consumption of petroleum all over the world today
is 40 million barrels, of which about 50 percent is for automobile use. That is
to say, auto petroleum constitutes about 35 percent of the whole petroleum consumption.
In accordance with this calculation, daily consumption of petroleum by automobiles
all over the world is over two million tonnes. At the same time as these fuels
are burnt, poisonous materials such as 500 million tonnes of carbon monoxides
(CO), 100 million tonnes of hydrocarbons (HC), 550 million tonnes of carbon (C),
50 million tonnes of nitrogen oxides (NOx) are emitted into the atmosphere every
year, severely polluting the atmosphere. At the same time large quantities of
carbon dioxide (CO2) gases, resulting from burning, have also taken the major
responsibility for the "green house effect".
scientists now believe that carbon dioxide is responsible for about half the total
"green house effect". Therefore, automobiles have to be deemed as the
major energy consumer and atmosphere's contaminator. Also, this situation is fast
growing with more than 50 million vehicles to be produced annually all over the
world and place into the market. However, at is estimate that petroleum reserve
in the globe will last for only 38 years . The situation is really very grim.
Addressing such problems is what a Green engine
does or tries to do. The Green engine as it is named for the time being, is a
six phase engine, which has a very low exhaust emission, higher efficiency, low
vibrations etc. Apart from these features, is its uniqueness to adapt to any fuel
which is also well burnt. Needless to say, if implemented will serve the purpose
to a large extent.
Compared to conventional
piston engines, operated on four phases, the Green engine is an actual six phase
internal combustion engine with much higher expansion ratio. Thus it has six independent
or separate working processes: intake, compression, mixing, combustion, power
and exhaust, resulting in the high air charge rate. Satisfactory air-fuel mixing,
complete burning, high combustion efficiency and full expansion. The most important
characteristic is the expansion ratio being much bigger than the compression ratio.
