are these sensors on my KAD 44 EDC ?

[simonfraser]

exhaust gas temp and boost pressure

Engine no: 2204408292

 

[petem]

No and Yes

exhaust gas temp and boost pressure

Engine no: 2204408292

Gas temp no
Boost pressure and temp yes .

 

[petem]

IIRC, you have...

RPM
Coolant temperature
Fuel consumption
Engine hours
Boost pressure
Alternator voltage

 

[simonfraser]

Gas temp no
Boost pressure and temp yes .

so for engine momitoring whats the difference between boost temp and gas temp ?

I think he means coolant temp.

Best thing to do Simon is look at the video I linked to a few days ago.

Gas temp is exhaust gas , you would need a thermo monitor in the exhaust to have that info .
Boost temp is the temp of air going into the engine after the turbo but before combustion.
There is a sensor in the inlet manifold which gives info to the edc system .

It might have a sensor but the Yacht Devices interface doesn't include it.

On my yacht devices I get

- Rpm
- oil pressure
- boost
- fuel flow ( both engines combined not individual)
- Voltage ( of engine loom only)
- engine hours
- oil temp ( which I only recently discovered)

Tnx guys

‘Boost temp is the temp of air going into the engine after the turbo but before combustion’

So if the boost temp is too high, the vanes wear more ?
What matters more, boost temp or exhaust gas temp ?

No it means the intercoolers not removing enough heat .
It’s the temp after the compressor side , the inlet side of the turbo .

Turbo has two sides .
One driven by exhaust gas connected by a shaft to the other “ vanes “ on the inlet which gives the boosting .
As it’s boosted it gets hot by compression so then it’s fed to the intercoolers to cool and re dense down .

So the inlet temp is important as if higher than spec your intercoolers need a clean .
They can salt up from the water side and sort of grease / oil film on the airside which reduces there ability to cool .
A higher inlet temp also has a knock on effect on elevated exhaust temps .
Overloaded ( your over sized props ) is gonna be the main reason for elevated EGT s .

Knackered / dirty intercoolers is just like rubbing salt on that existing wound .

They are both linked but answering your Q EGT elevation matters most .

What sort of EGT numbers are you getting planing ?

 

[simonfraser]

'What sort of EGT numbers are you getting planing ?'

only have an EGT alarm at the mo, this is not going off when planing
but beginning to understand the overload / temp issue

got side tracked with a KAD interface, but that is still not going to give me EGT readings unless i fit a new sensor
recon a proper EGT gauge is better use of my money than a fancy KAD interface
once i have verified the revs, another thread is looming here ....
