Hi,
Has anyone used paraffin oil mix for running? Is there a fall off in power? What experiences have been encountered?
With the high cost of petrol fuel has anyone else considered using paraffin?
Cheers

Not worth the trouble Mark .The engines were not designed for that fuel .The Kerosene or Paraffin that you can buy now is not the same as the old Power Kerosene. I have several engines that were specialy designed for that fuel ......start up on Petrol and when the engine is HOT switch over to kero and then they have to work hard to maintain that heat in order to vaporise the kero. The only thing approaching the old power kero is Jet A aviation fuel. A club that i used to belong to has a early Hornsby Ackroyd oil engine and they use Jet A . Sometimes you can get it from your friendly helicopter company .....they ditch it when it passes it's use by date .
AS I say dont try it ,enviromentaly it is not good .It will smoke the place out as well as fouling your plugs , stick to petroil!
Good on you for thinking out side the square! |

One of the troubles with using kerosene is oil does not seem to stay mixed well with it and therefore the lubricaton of the cylinder wall and con rod suffers. Lathrop advised his customers that mixing oil in gasoline didn't lubricate properly and he retained his oil injector pump for the BIG END and drip oilers for the cylinder wall. These were also used on his engines with so called "hot heads" when burning kersosene. Apparently his customers preferred to mix the oil in gasoline rather than mess with the pump and cleaning and filling the drip oilers. By the way so called "hot heads" were simply a steel plate with no water cooling which insured ignition of the kerosene once the engine had started and heated up on gasoline. |
