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.
