6 stroke motor?
- Thread starter noJeepshere
- Start date
I think it was Fueling that made a six stroke motor where after the exhaust stroke, water was injected into a compressed cylinder and the steam expanded and sent the piston down again. It cooled the motor and cleaned it. Pretty efficient.

I dont get it? is that kinda like overdriving the crank? The pistons goes one stroke which turns the crank twice?
or maybe im not seeing that corectly.
at any rate it looks like more to go wrong

O my timing chains went, welp if ya thought it couldnt get any worse than interference it just did lol
I see twin turbos in that video...why mess that up with un-need technolgy. If there was a better design than the current four stroke engine (for automotive applications, other than diesel) one of the OEM's would have tried it by now.

its crazy lookin.its like it stalls on the compression stroke them pops and double rotates the crank.doesnt look too much efficient to me.just more to maintain and have go wrong.
I've heard about this in diesel engines. Never seen it or heard of a production engine with 6 strokes.
I'd worry about blowby. The cylinder sits at the top of its cycle every time, thus allowing the built up gasses to leak out. I really don't see how it could be any more efficient or powerful than a 4-stroke design. Just a more complex way of rotating a stick, with greater chance of a massive fail.

looks expensive!
The idea with the 6 stroke motor is that you inject very high pressure water during the second compression stroke. The high temperatures in the cylinder instantly boil the water which expands and forces the piston down.
This, in combination with the inherent cooling that happens when fluids jump to the vapor state practically eliminate the need for a cooling system.
Basically, you're taking the wasted heat that would otherwise vent to the atmosphere via the radiator and transmit it into power. The idea is very smart IMO. However, there probably is some reason it hasn't really caught on yet.

I like the idea a lot! But it looks expensive! Maybe that's why it hasn't caught on? I am still waiting for a 1/2 ton diesel pick up.

6 strokes have been around in various forms using both water and air for the extra power stroke for almost 100 years. IIRC they have been used in staionary uses like power generation but have not been used for transportation/vehicles.
Good idea. They are very fuel efficient. But not sure if it would work good in a vehicle with all the various RPM ranges needed.
Plus the water injected engines would be prone to rust if they sat for long periods. You could not use tap water its too hard. They would need treated distilled water to prevent deposits from building up in the combustion chamber. You would also need a water tank at least equal in size to your fuel tank. So you would add quite a bit of weight to the vehicle.
