Problems with my kompressor

 

[Bondo]

Ayuh,...... Welcome Aboard Jan,....... Ok, so you have a 2001 kamd 44, which I believe is a Volvo diesel motor, 'n the turbocharger isn't working right,..??
The compressor, is it engine mounted,..?? is it necessary to help the turbocharger,..??

Obviously I don't know alot about your motor, but I do know abit about diesels, 'n never knew one that needs compressed air to work,....

Have the motor's fuel filters been changed, since this problem started,..??

Hi Bondo Thanks It is a Volvo Penta 260 Hk .yes all filter is changed when the boat Come into wather after winther on land.before there was no problems. The kompressor help the motor /turbo to Come fast op on rpm an is on engine mounted from new(sorry my English is not wery vel) regards /Jan

 

[Bondo]

Ayuh,...... Yer doing fine Jan,...... There are others here more knowledgeable than me, so hopefully one of them has a better answer for you,....

If you don't get more answers, I'll move this to the diesel motor forum, but I'll leave it here in the Volvo forum for now,....

Volvo uses both a supercharger for holeshot and a turbo for top end.

Most of the time, the supercharger kicks out before the turbo spools up and the motor falls on its face..... Right as it's coming out of the hole

It's a big complaint of Volvo diesel owners. And no, Volvo won't change the software to hold the supercharger for a few more RPM

A "cheat" is to have the turbo rebuilt with new bearing pack and new wheels which helps it spool just a tad sooner.

The correct fix would be a software change...... Or a bit more motor

Hi Bondo thanks for your reply.

thanks / Jan

First thing I would do is check the turbo. Remove the air filter and see if the turbo vanes spin freely. If it doesn't spin freely, you need a new turbo or turbo rebuild.

The supercharger (compressor) is activated by an electrical signal (12V I believe) that engages a clutch on the supercharger to connect it to the belt pulley. I'm not familiar with the specifics, but I would make sure any electrical connections on the supercharger are clean and making good contact. Beyond these things I would get a mechanic that is familiar with these older Volvo engines.

I agree, pull the inlet hose off and inspect. with just a small flick of the tip of your finger, you should be able to spin the propeller for a long time.

if it doesnt spin, the bearing pack is gone or other debris may be fowling the turbo

My buddy used to keep a pair of rebuilt turbos on-hand at all times, often swapping out on a trip. then he would have the one he pulled sent in for a rebuild.

using google translate because I do not speak Danish.


Jeg er enig, træk indløbsslangen af og inspicér. med blot et lille svirp med spidsen af fingeren, burde du være i stand til at dreje propellen i lang tid.


hvis den ikke roterer, er lejepakken væk, eller andet snavs kan løbe rundt i turboen


Min kammerat plejede at have et par ombyggede turboer ved hånden hele tiden, og skiftede ofte ud på en tur. så ville han få sendt den han trak ind til en ombygning.

Hi Horigan ant Scotty Thanks for comming back.
Now I user google translat
To be completely sure that I have explained my problem correctly. My 2 compressor starts as it should for about 2 minutes when I start my 2 engines. When I then give throttle, both engines reach op to about 2000 rpm; I continue to give throttle, but only one engine increases in rpm, while the other one only wherry slowly rises in rpm. After about 60 seconds, it reaches the same rpm as the other engine. I can see that it is not pulling the solenoid coil on the motor that is slowly increasing in rpm.
Can it still be the supercharger..
Thanks Jan

Sorry Can it still be the Turbo

 

[Scott Danforth]

could be the supercharger clutch is bad

I can see that it is not pulling the solenoid coil on the motor that is slowly increasing in rpm.

I would also check the turbo. by 2000 RPM, the turbo should be spooling up

 

[Lux]

Thanks I will try this and come back to you
Again thanks BR/Jan

Hello, is there anyone/mechanic here in this forum who knows well about the older Volvo Penta TAMD 44 from 2001 with a compressor, as Horigan recommends me to seek? Thank you.
( Horigan saed.. Beyond these things I would get a mechanic that is familiar with these older Volvo engines.)
