Electric warming of vaporizer/convertor?

Post by BigBlockMopar » Sun Dec 04, 2016 5:34 am

Are there any kits or models that warm up a convertor electrically, instead of with engine-coolant?
Although I can imagine the power draw of an electric heater inside the convertor would be high and put a strain on the electric system of a car.

I know on the old tractors they had a vapor valve for warm up.
A friends harvester will ice if he drives it before he shows some water temp. He doesn't have the vapor valve for warm up.

Presumably, the need for an electric heater is a cold weather issue. Have you considered adding a block or circulation heater to your cooling system? It is very common to see cars "plugged in" overnight here in Canada.

I did the calculations once and came up with something like 1.1kW of heat required for the LPG supply of a Citroen 2CV at rated power of 20kW - Only for the evaporation, let alone the superheat and ambient losses. Used exhaust heat instead, see viewtopic.php?f=5&t=1667#p12532
There is a kit that provides approx. 0.7kW electrically for dedicated setups to assist the cold start, but still hot water required once you draw real power:

well, take a closer look. The AC CS is exactly that.
Can't change the laws of thermodynamics and the limits of 12V automotive electrical systems.

problem is that its only 250hp and I have a 7.4L V8 engine....250hp would be awesome for now, but I hope to make a little more in future

and its rather expensive reducer compared to a KMG Gold even the Turbo version.

a simple system of simple parts would make a good solution "I think".

- one or two glowplugs from a diesel engine?
- piece of pipe to install the glowplugs in
- simple adjustable thermostat set to 30 or 40C to turn off the glow plugs
