Quick Answer: How do you start a main engine?

What does starting an engine initially require?

To make an engine start it must be turned at some speed, so that it sucks fuel and air into the cylinders , and compresses it. The powerful electric starter motor does the turning. … The starter needs a heavy electric current , which it draws through thick wires from the battery .

What is slow turning of main engine?

The slow turning may be used: On a slow speed engine during maneuvering. If the engine has been stopped awaiting a movement for more than a set period (usually 20-30 minutes) then when an order is given and the engine control moved to start, instead of the main air start opening, the slow turn valve will open.

What are the advantages of low speed engines?

One of the advantages of low-speed engines is their part load efficiency which varies very little over a range of outputs between 50% and 100% load. Whereas gas and steam turbines outputs tend to fall as the load decreases, that of a low-speed diesel engine is relatively flat over a similar load range.
