Description
Industrial Diesel Engine Efficiency Features and advantages
From the start of their industrial use, diesel engines have
continuously made a great improvement in its features. They also
overcome their earlier disadvantages like noise pollution and
operating cost.
Compared to gasoline, the compression ratio of diesel engines is
always higher. This combines the development of high peak pressure
inside the combustion chamber and, therefore, on the crankshaft.
The spark will ignite in the gas engine due to compresses of the
fuel-air mixture. A diesel engine compresses the air to such a high
pressure and temperature that ignition occurs with the fuel not
requiring a spark.
The piston stroke occurs in a diesel engine to compress the air
more. Diesel burns consistently and quickly compared to gasoline.
So, for one liter of fuel, you have more energy in diesel.
Diesel engines are used for electric Genset because of its low
maintenance cost. The low operating temperature and no absence of
spark ignition system, the engine are easy and simple in use.
The elimination of the electrical ignition system reduces any
parasitic load, because of this feature reliability of diesel
engines is enhanced.
The diesel engine can work for a long time. Because of its
long-running durability feature, the diesel engine power backup is
one of the prime choices of customers.
For example, one 20000 rpm water-cooled diesel unit can operate for
13,000 to 32,000 hours without any major maintenance. That same rpm
water-cooled gas unit typically operates for only 8000-12,000 hours
before it needs servicing.
If the diesel engine is so efficient, why it is not the first
choice for everyone?
Day by day, the improvement of diesel engines has set a new
example. But the natural gas or propane fuel engines, allow them to
compete with diesel for use in rugged and remote services.
The cost of diesel fuel and availability is also one major factor.
Because compared to diesel fuel, natural gas is less expensive.
The storage, transportation, fuel spills possibility, and the risk
of unavailability is also a few major factors that affect relying
on diesel. The diesel engine lifespan and the noise factor make
them impractical in some environments. For example hospitals,
libraries, and other populated areas.
Apart from that, the use of diesel engines is wide-scale, because
of its lots of advantages. With the use of new technology in diesel
engines, the gap between the natural gas engine and diesel engine
will be no longer so clearly defined.
