Running two engines connected via chain in one dir :-)

A twin cylinder engine firing order can only be 12.

Your will now be 12-12 or 1234.

A starter motor only needs enough power to turn the engine over the compression ., if you time your cylinders to 12 -12 and not the compression together your original starter will be ok

When its running you can set up the carbs 2 -or 4 by listening with a hose pipe int the carb intake.

25 years ago we didnt have fancy carb balancers. I used to set up flat 12 Ferraris with 4 x triple venturi down draft Webbers carbs, its not difficult.

 

So this engines are 1cyl engines?

If both engines are mulicylinder it will be more restriction on bearings and stuff+ more than one cylinder can copress at the same time.

I made a 2x carb setup once on a 4cyl and I just start it once because I later decidet to go for injection. It's 6 years ago now and the car still has it'scarbs on and newer started time fly

 

Two freewheels on prop shaft, each linked with an engine. Could be workable IMHO.

 

A waste off money and add more weight. Just link the two engines togheter and threat it as a multicylinder configuration with more than one carb. Anny mototcycle mecanic should have no problem adjusting it.

 

High guys,

it is possible, please see twin packs from turbine helicopters. The whole miracle is to use a drive wheel (like bicycle) which is free turning in one direction, so you can start the engines one after the other. Even in engine failure or stop condition you will not overload the drive system.
POWER synchronisation should be done via fuel flow and manifold pressure.

High Syed,

thanks for correction and please pardon me, I am austrian, so my native language is not english.

Hi, Jet A1,

Your thinking was inline with mine.

I am with you regarding English, not my language either.
Am I right to assume that Austrian and German languages are not much different?
Regards and welcome to the forum.

High Syed,

I would say, german is a slang of austrian!

I newer thought about that, but then if 1 engine is not enough to keep the howercraft running it's a waste is it not?

With two engines both able to keep it running it would make sence.
Maybe a emergency NOS system for extra power if one engine fail

 

High,

I am not commenting on what is reasonable, but there will be special needs why to do so.

I love your post, I worked alot with paralel running off propulsion engines and generators and I gues I just have a great interest in it.

So how dos power shearing happend by using manifoil preshure?
