Particularities
The engine speed control is automatic without external intervention. Only the commands for start and stop of the motor can be adjusted on the mechanical speed controller. This means that the diesel engine works externally without any auxiliary voltage.
The engines of this type were formerly used in smaller vessels of inland shipping. The low speed of 1500 rpm used by these motors results in long service intervals and high life cycle times.
Turbocharging and intercooling are foreign words for machines of this age and type. The application of a pure suction motor brings a very decisive advantage. Most technically interested surfers have certainly come across the term "turbo lag". When changing from idle to full load, the turbocharger needs a certain amount of time to reach full speed. Such a load change now occurs when the load is switched on. Once the generator requires the maximum power from the diesel engine, this can not be provided in the expected performance. The speed breaks down and it can even happen, that the diesel engine stops. This can happen mainly when the generator should start large electric motors.
