Rotory Engines on Gas Discussion.
« on: April 29, 2007, 01:35:50 PM »
After installing lpg on my 1st gen I thought I\'d start this thread to discuss the LPG setups for other rotarys.

I\'m currently running a gas carb setup on the 1st gen using a impco 300a and impco vapouriser. My 12a is tired and I\'m fitting a 13b EGI into the 1st gen in the next month hopefully.

A lot of people have asked me if im going to be doing the same to my FD and I\'ve been doing some heavy research on the setup needed. The big questions at the minute for discussion is if the car is running a microtech setup can you do a hybrid setup just using the microtech. So that the car runs normally on gas off boost and then adds petrol once higher fueling is needed. We already run secondary controllers for additional banks of petrol injectors so the technology may already being used by the higher powered cars ?

Reading threads on Ausrotary alot of the guys are looking into liquid gas injection. This is still in the development stage and nothing is available.

The big thing that is interesting me at the moment is the Stealth GTi setup that uses the original injector postions with the gas being vapourised in the injector with a pressure regulator off the gas tank. It currently is still in testing phase but looks a very good setup for n/a and turbo setups. If this could be controlled by a microtech or pfc then this would be very interesting.

What do other people think about this in the light that super unleaded is teetering on the £1/lt and LPG is around 40p/Lt (near me) and the gas is 110ron and doesn\'t nox the same as petrol in higher boost setups ??

Find a system that well give me enough fuel Shaun and i\'m intrested. I\'ve been watching the Ausies playing around with direct injection but no one seems to be there just yet. I\'ve a 85litre fuel tank behind the rear seats which would give ample room for a large gas tank if removed.

The other reason why i bring the stealth gti setup into interest is because i could use an EFI ida setup on my 1st gen then. It would need the electronics to do it but the setup would look very cool and very clean.

The stealth injectors would just plumb into the standard egi intake setup too so that would be a very clean setup too. Wouldn\'t be a big job to hide the regulator and keep a very tidy engine bay. Would just need a microtech on a custom loom to get it to work !

If this does get sorted it would be a fab conversion!! I\'m running an LPG set up on the work hilux & the running costs are about £10 a week (normaly nocking up 100miles a week!!) this would also make running a rex (or any turbo car) alot more afordable, although the initial outlay would be a fair bit!!!

We used to have a member who ran an EGI on gas for a few years and he claimed it went better and gave the equivalent of better MPG as well, sadly the car is no more though.

Rotechnicks in Reading have done a lot of work with Gas on Rotarys in the past.
All the best Clive

It was probably a multipoint setup. The biggest question with that is if you need 4 injectors or 8 ?? Half of that system is how they have got the ecu to talk to the electronics module !

If the GTI injectors have enough capacity then they could be a go with my set up shaun. It\'ll be intresting to see what sizes they are looking at making.

I\'m very interested in this, then see if you can run it on hydrogen! I know Mazda had some sucess with a RE hydrogen engine...

...But there was a small co in the states that had converted a Corvette to run on Hydrogen stored in high pressure tanks, but then also sold a big solar setup that would make the hydrogen from water :D

It\'s all a bit pie in the sky but for short range and low useage it would be very cool!

I\'ve stuck this as it has the potential to be a very useful thread :wave
At the end of the day, it\'s meant to be fun - not a political movement! :burnout

Not for much longer :D

Cheers fpr the sticky. Thought I\'d start this more to get feelers out on what other people knew and experiences. Im learning with gas and the carb setup i have may not be the best option. The 1st gen may get converted to efi and stealth gti injectors later in the year when they are released.

Found the hydrogen link...

http://www.switch2hydrogen.com/

Could be interesting if you car is already running on gas!

Theres an interesting read on rx7club about some guys running hydrogen on test engines. Looks promising, but the equipment is completely different to LPG. The hydrogen is chemically bonded where as LPG is just a tank !
