I see you're using the original air valves from FB. Mine leaked like crazy after a couple of cycles. Ripped them out and put Robarts in. Problem solved. How has you're been holding up?

Hello. I have problem starting my KingTech turbine. 8-10 times with bad start before finaly starting. Starter overload is the message. Any idea?

Make sure the turbine can turn over with just a butterfly breatheing on it. The starter should be able to spin the rotor to 2,000 to 3,000 rpm easily in order for the propane to ignite for the preheat cycle. Monitor the read out during initial start up. Check to see that the RPM's are reaching this point. If not there's a problem with either a loose connection somewhere, a dragy starter motor, or possibly a battery issue. You can also monitor the voltage on the second screen. If it drops too low a condition may exsit where the current is increased to try to make up for the voltage drop. Same condition may exsit with a loose connection. DO you have gas ignition?
See what you come up with.

Turbine spin easely. Gas ignit fine, turbine spool up to where fuel pump start and then it shuts down with starter overload in display. New 7,2 2600mAh lipo. The diode on ecu is blinking during start. Bad conection or is this normal?

LED blinking shows fuel ramp.

Starter overload simply means the ECU has detected excessive current draw. I think you have a dodgy starter motor or it's not aligned properly. Have you got a fod guard on it and could that be pushing the starter off centre? I have also seen some engines that ended up with draggy bearings after 2 stroke oil had been used.

Need more info. Is this a new turbine? If not when it was new did it operate properly? How many hours on it? Did you change anything that might be linked to this condition? With the fuel line disconnected from the turbine, do you have a steady stream of fuel coming out the end of the fuel line when operated manually? Might be one of your settings may have been changed accidentally. I can copy my settings to confirm what you have set. What does the RPM's read when it shuts down. Might give a hint of what stage it is in when the shut down occurs. There are settings for the starter through out the start sequence that we can look at.

Thanks fore response. Turbine is brand new. Only 4 successful starts until now and a total of 6min run time. No change on any parameter. A steady stream of fuel comes out the end of the fuel line when operated manually. The stream starts slow and build up to full in 5sek or so. When operated manually everything seams to work ok. Don’t know about the start engine sins I don’t have any to compare with. Rpm on shut down I don’t know but I will have a test run today and video the run. <span lang="EN-GB" style="FONT-FAMILY: Arial; FONT-SIZE: 9pt; mso-ansi-language: EN-GB">If you can sent me a copy of yours setting I can compare with mine.

Here is video from todays test run. Shut down (starter overload) seams to happen at app 22000rpm. http://www.youtube.com/watch?v=tO9Jq59YuWo

Your fadec is not correctly programmed, did you modify any parameter? do you have access to startup parameters? If yes, please list.

Gaspar

Fadec parameter readed at trim low:

Full power speed 145000
Idle speed 45000
Stop speed 30000
Start /min. temp 0100 dgC
Max temp 800 dgC
Accelration delay 035
Deceleration delay 015
Stabilety delay 130
Pump limit 1020

Version 5.63

STARTUP parameters , please.

Sorry. Startup parameter:

Pump start point: Auto+2
Pump start ramp: 006
Glow plug power: 35
Start gas adjust 085%
Lov batt. volts: 6.0v
Starter power at ignition: 080
Ignition max rpm: 04.000rpm
Ignition min rpm: 02.000rpm
Preheat time: 2.0s
Rpm gas off: 29000rpm
Starter power at preheat: 125
Rpm 100% starter power: 22.000rpm
Rpm off starter: 25.000rpm
Rpm to reconnect starter: 20.000rpm
Start mode: Auto gas

Check your pump start point and pump ramp. The starter and pump work together on initial startup when the fuel valve opens and pump starts. Also your preheat needs to be set properly for proper ignition of the kerosene. In cold temps such as your location may need to be longer than standard setup of 2 seconds. If set at 2 seconds, try increaseing it to 4 seconds.
My settings are:
Pump start point Auto+4
Pump ramp 005
Pre heat 2 seconds
Starter power at ignition 100
Rpm gas off 30,000
Start gas at 40%
Starter pwr at pre heat 100
The best I can see from your video is you do have a command for pump start by the value at Pw (pump power).
My quess is if preheat setting is set at 2 seconds and the pump start point and pump start ramp are set accordingly then you may have a problem with the fuel valve sticking or/and the pump not starting properly on the failed attempts.
Are you using propane only or are you using propane/butane mix?

I am with a problem, the turbina working, and when I go to accelerate the turbina stop, in fadec write SPEEDLOW..
What can be?

Thanks

Fernando

Just change:

Starter power at ignition: 070
Starter power at preheat: 070
Rpm 100% starter power: 30.000rpm

After verifying information from colleagues at KingTech, we endorse suggested settings provided by Gaspar, Thank you!

hi Fernando, this sounds as if it could be some sort of magnetic interference to the RPM sensor from other components, like a pump or valve being too close to the front cover of the turbine, or perhaps check your RPM sensor cable connection, extension........

Hello Barry

I already did many tests, I already changed extension of RPM, line of fuel and idle for 48000rpm without success.

Would you have another solution?

My friend spoke that can be obstructed beak.

Thanks

Fernando

Fernando, is this K-80 the one in your Velox? what's its serial number? Could you please give more details of the problem that you are having? Perhaps even send pictures of your setup.

Thank you,
Barry

Barry, the turbine is in my velox, the serial number is 0908130, the turbine is running, when I start to accelerate it stop and in data appear, SPEEDLOW.
I am putting pics for you.
Thanks

Fernando

Hi Fernando, Sounds like you may have a possible fuel flow restriction? or air entering fuel system? Be sure that you install wire twist tie wraps around all fuel tube fitting connections. Replace those plastic tie wraps on your fuel tank as they can also let air in and are not recommended, Check that your fuel breather line has no restrictions or kinks, Check that your fuel tank clunk pickup has no restrictions also. Felt clunks are not ideal as they can cause fuel flow restrictions also. Check your fuel pumps flow rate also. It does sound like something straight forward is causing the problem so just going through the process of elimination for now.... Please let us know how you go

Cheers- Marty

Marty, I believe that the problem not is in the fuel line, when I go to accelerate slow it arrive the full 145000rpm, now when I to accelerate normal it stop, I will go to make a video.
thanks

Fernando

Hi Fernando

We had a similar problem with the Kingtech, the only way we could solve it was to re-route the rpm pick-up lead away from all the other leads, including servo leads. Worth a try?

I passed the rpm thread on the outside, and it didn't solve...
