Question

What's a governor used for in a marine diesel engine?

Answer 1

To limit the rpm, diesal engines are notorious for redlining.

Answer 2

not only to keep it from over reving but it also holds the boats speed,think about a cruise control on a car, when a car goes up or down a hill the cruise control adjusts the throttle so you don't have to.when a wave etc. slows the boat the governor automatically adjusts the engine rpm.s

Answer 3

to limit the maximum revs per minute. its normally fitted to the end of the injection pump.

Answer 4

A governor is used as a speed limiting device.  It slows the engine down to prevent over rpms.  An over speed trip shuts the engine down to prevent major damage.

Answer 5

A govenor on a diesel engine is used for setting Maximum rpm, Idle rpm and to Maintain rpm under a load. There are different types as well. For instance a generator has a govenor that keeps the engine spinning at the set rpm, as soon as it starts it is going at that rpm. A variable speed govenor allows the operator to set the rpm and then would maintain that speed, no matter what happens to the load ( like going uphill or downhill ).

Answer 6

I know a lot of cars have a governor in it that makes it stop at a certain speed.

My friend used to have a truck that would no longer accelerate after it hit a hundred, which was good because usually by then, I was cowering in my seat praying for my life....

So thats probably whats on the boat, is a top out speed amount, however I believe governors can be removed by professionals, although not reccomended, they are there for a reason.

Answer 7

To maintain full correct fuel & power under fulll loads>Safe operating range>

Answer 8

I would think the same as in any engine, to keep you from over-reving.  Nothing worse then throwing a rod.

Answer 9

to prevent engine from producing damaging r.p.m.'s

Answer 10

I would assume it is used as the same on any engine. To control or limit the maximum RPM of the engine within the design parameters of the engine designers.
