Redefining Diesel Generators

There are a lot of biases against diesel generators. The reality however is that there is little basis for such prejudices. To begin with, it quite well known that in industrial settings, diesel engines are most favoured. And this has been the trend for so many years. In terms of reliability, cost and efficiency, diesel engines have proven to be very worthy. In comparison with other fuels, diesel comes out as a winner – it is more reliable, cheaper and more efficient. Also, it has an extended life cycle as well as lesser maintenance requirements. This is backed by genuine technical reasons.

One of the main technical issues when it comes to diesel generators is its internal combustion system. It is the generally accepted that the greater part of the energy from fuel is mostly converted into heat instead of useful power. Add this to the fact that some of the power is also used for cooling. Under such conditions, it is essential to point out that the temperature of a diesel engine that is running is much cooler than the internal combustion engine that runs on other fuels. Ergo, more power is transformed into useful power. And the energy required for cooling is greatly reduced. diesel generator set

Another reason for the efficiency of diesel engine is its compression ratio. The rule is that efficiency of an engine is directly proportional to its compression ratio. Thus, the higher the ration of compression, the better is its efficiency. For diesel engines, the compression ratio ranges from 14:1 to 25:1, whereas the ratio of compression of engines running on gasoline ranges from 8:1 to 12:1.

The resulting efficiency from internal combustion system and compression ratio literally translates into decreased fuel costs. In fact, the cost of fuel for engines running on diesel ranges between thirty percent and fifty percent lesser than the cost of fuel for engines running on gasoline.

Another advantage of diesel powered generators is that of low maintenance requirements. This also leads to longer life for diesel engines as opposed to gasoline engines. The main reason for it is the fact that spark plugs are not featured in diesel engines. Thus, regular replacement of the same is not necessary. Another reason is the low temperature feature of diesel engines, which was already discussed above.

To complete the picture of an advantageous use of diesel generators, one must debunk a pervasive misconception – that engines that run on diesel, in this case, generators, are smelly and noisy. While these may have basis before, the same cannot be said for today. The developments in technology have ensured that engines running on diesel are relatively quieter. Improved insulation materials as well as utilization of mufflers account for the low noise level of the running diesel engine.
