Figured some of you might find this one useful, it is a 12V 20w glow ignitor that gets hot enough to ignite propane, kero and other fuels. It heats up in a couple of seconds so no delay to speak of, I plan to fit one to the bike engine so I can save some space by removing the spark ignition module. crystaltechnica.com/product/ml12-20-rhp/Cheers! /Anders |

Hello Anders, i use a 30W elemnt, 6Volts but the more watts, the more heat. Be very careful not to intoduce too much kerosene into the heater or a wet start is granted  Search youtube for "Gerald Rutten kerostart" for some videos There is not much to it, just the heating element and a very basic burner  |

Glad to see you here, the kero starter you´ve build for your GR180 looked sweet so I´ll make one for my JU-02 engine so I won´t have to drag the propane bottle with me everywhere. I´ll use a 12V heater since that is the current I run the bike on, most likely I´ll fit a separate micro fuel pump for the heater so I won´t have to add solenoids and pressure regulators to the main fuel line. Make sure to write up an introduction for the folks here, I am sure there will be some jaws dropped if you show them the tools you´ve built for your workshop! |

Yes Bjorn....do tell...I like seeing special tooling. Oh...and welcome!! Make a new thread for it so as not to Hijack Anders' thread. Cheers, Smithy. |

Is that kero starter just a glow plug combined to a fuel line? Does it need a hollow chamber where the fuel is injected? That would be a great upgrade in our bike too, once we get to rebuild it..

So....... could I replace the cracker boxes/ignitors on the Rovers with this? To my mechanical mind they look a lot simpler and safer.

To explain the kerostarter I made a bit. If you look at the 6V elments on chystaltchnicas homepage, you see that they ar perhaps a little vit different to the 12V elements ins style, but the heat elment is put on a stainless fitting with a hole about 1mm larger in diameter than the element itself. A tiny ammount of kerosene is introduced in this space and the nose of the ignitor enters the combustor.
First of all, my turbine is very small, it is a GR180 of Gerald Rutten's design, I just copied his ideas for a kerostart..
I run my turbine with a xicoy kero fadec and it is equipped with a electric starter motor. Start sequence is:
Heater on
Starter motor on
At about 2000rpm kerosene is introduced to the ignitor followed by rpm increase as soon as ignition is detected via temp probe
Switchover phase (main fuel opens, igniter fuel decreases and rpm increased) happens at about 4000 rpm
At about 10000 rpm the kerostarter fuel is shutoff and fuel/rpm ramp starts
Starter motor is disengaged at 20000 rpm
Idle is at 35000
I found that a late switchover makes for wet/hot starts, the kero igniter seems to dribble a lot of fuel into the combustor if left on too long, less fuel is better! Had to make a syringe restrictor on mine.
This is in essence a very good way to make a flame thrower, some experimentation is in order to make this work. I would not dare to use this on a manual start engine.
Introduction... Hm, good idea!

How about using a Diesel glow plug?
