Diesel/Gasoline Engines Flashcards
Components and workings of various non-steam engines
What are the main applications of diesel engines in naval ships?
Propulsion for medium-sized combatants, auxiliary vessels, some larger ships, submarines (not US), merchants, supply transport, and emergency power generators.
During which stroke of a four-stroke diesel engine is air drawn into the cylinder?
Intake stroke.
What is the main advantage of a two-stroke diesel engine compared to a four-stroke diesel engine?
Higher power to weight ratio and less complicated valve train.
What are the three basic components of a gas turbine engine?
Compressor, Combustion Chamber, Turbine.
What is the primary purpose of the compressor in a gas turbine engine?
To draw in air and compress it for the combustion process.
What is the primary advantage of the LM 2500 gas turbine engine used in DDGs and CGs?
It is compact, light, easy to maintain and repair, and has a quick start time (~1 minute).
What are the types of combustion chambers used in gas turbine engines?
Can, Annular, Can-annular.
