Not quite true. On 2 stroke and 4 stroke engines you have a crankcase pulse in the case of a 1-Cylinder engine as well as a two cylinders when they are opposed and have a 180 degree phase difference, meaning that both pistons move away and towards the crankshaft at the same time. The pulse is simply created by the displacement of air from the backside of the piston. With more than two cylinders the engines are typically balanced so that the pulse becomes weaker.

It will depend on the needle and seat in carby, the float level and/or the diaphram position. In most float type carbies as the fuel is used the needle will allow the vapour lock to bleed off. In some floatless, diaphram carbies the vapour lock will just move from the fuel line into the diaphram mechanism of the carby, must cursing when this happens. regards Barry Kruyssen Cairns, Australia RAA 19-3873 kr2@BigPond.com http://users.tpg.com.au/barryk/KR2.htm ----- Original Message ----- From: Mark Jones To: KR Net Sent: Wednesday, November 17, 2004 9:01 AM Subject: KR> Vapor Lock In my research on the Facet pumps, I found a statement that "the facet pump virtually eliminates any possibility of vapor lock due to the fuel being forced through the system under pressure by the pump".

So vapor in the line will not stop the a facet pump working.

Hello Mark and Net Some people think of vapor lock as a void or pressure area that fuel will not pass. I found this definition on the internet. I also went into a Sunoco site which listed some temps and the #260 sticks in by head from that reading. Fuel Terminology by Rich Rohrich Vapor Lock - Rapid formation of vapor in the fuel lines or carb, that causes a restriction in flow. Vapor formation begins to occur in fuel lines, pumps, etc. when the fuel reaches a temperature where the vapor pressure of the fuel is equal to the pressure in the system. Gravity feed fuel systems (positive pressure) tend to be less prone to vapor lock than snowmobile type vacuum pump systems where negative pressures exist. End It is a dynamic process in which vapor pressure is created by the boiling fuel. I was able to watch vapor lock once in a boat, that had a mechanical fuel pump, clear plastic filter and metal tubing. The vapor lock was caused by heat transfer from the engine block to the pump and tubing, in the enclosed compartment of the 440ci engine. You could actually see the fuel boiling (vapor lock) in the plastic filter. I would suspect that if the temp inside the engine compartment gets high enough to cause the fuel to go to vapor that, even though the pump will continue to push the vapor and what ever fuel it can, that the quantity of fuel exiting the carb could and would not be sufficient to maintain the correct ratio. Once it starts boiling, it will continue until the temp in the compartment decreases. As a guard against vapor lock, some Piper aircraft place the pump and gasolator into a compartment which has pressure air from the cowling ducted to it. The use of fire sleeves is another way to prevent heat from getting to the fuel lines. My turbo KR will probably need more Heat protection and or cooling air, in the summer.

KR prices seem to go in cycles. I agree that a good KR is worth every bit of $16K, but you see a lot of them go for half that. I guess that is what happens when you have so few for sale and so few buyers out there. When buying or selling a KR your best bet is to have patience and wait for the timing to be just right.

I am flying a Renegade with a Rotax 582 two-cycle engine. It has a pulse powered fuel pump mounted on the firewall. That engine burns 5 1/2 gallons per hour at cruise, so the output of the pump would be more than adequate for a KR. The hose connecting the crankcase to the pump must be fairly rigid--rubber hose or ordinary urethane tubing will dampen the pulses. I would assume that the crankcase pulses in a four or six cylinder engine at 3600 rpm would not be too far off the pulses in a two cylinder at 6600 rpm. Any Rotax dealer should be able to provide you a pump for around US $30.
