Fuel Vapour System - Got it working!!

[alan]

Has vaporizing using microwave resonance already been considered or tried, to create mist from gasoline?
As like mist can be formed from water using this technique.

Hi alan,
Ultrasonic vaporization of the water may be better, for one it takes less energy than heating it with a microwave, also the water vapor will be entering the combustion chamber colder and denser. This will allow it to expand even more when it is super heated in the combustion chamber producing more power.
Just a thought.

How about ultrasonic vaporization of gasoline?

Hi All,


Great suggestions from everyone, so I'll give it a try one at a time.
Any ideas about what ultrasonic vapourizers cost? I may have to explore my old camping kettle first if vapourizers are pricey.

Luc that makes sense - in a way its trying to find optimum air/fuel vapour density for the engine. I'll still heat the fuel to keep it a constant temp. One of my next fuels to try vapourizing is diesel - I suspect it will work and if it does I'll be excited - it means you could in theory drive a normal engine possibly on vegetable oil ( with a small ammount of a solvent like petrol included...)

OK - Results to date -

On 95% ethanol ( alcohol ) the engine consumed 0.88 Litres/hour of running at full throttle ( but no load ). I'm assuming some loss to the atmosphere of fuel of say 10%, so that might bring consumption closer to 0.8 L/hour.

To put it in perspective, at highway speeds of 110 km/h ( 70mph ) cruising for an hour, a typical car would consume 8 L/100 km at 100 km/h ( e.g. a Toyota Camry ) so in effect 8 L/hour of petrol ( not alcohol ) . Obviously a car weighs a lot more, and the engine is loaded and its *not* running at full RPM either, where as the 5 HP Honda is running about 2/3 full throttle.

I''m hoping to try running on petrol vapour this weekend and see how much it consumes, then try running it on petrol through the carburettor and see how we go. I'll post the rsults back once done.

The diesel results will be interesting.

Cheers

As long as we are talking about ultrasonics, take a look at this:
