Tuesday, 20 June
The firing pressure inside each cylinder on the main
engine is just about 120 Bar, or 1,752 PSI. This is the pressure
caused by the combustion of the fuel inside, and is what forces the
piston downward in the power stroke of the cycle.

Answer: |
|
| |
|
|
| |
No. You are right that the higher
horsepower propulsion diesels are 2-stroke but many, many marine
diesels are 4-stroke and as Diesel-Electric propulsion is becoming
more popular you will find more and more 4-stroke medium speed
diesels for power plants in ships. |
