1-Stroke Engine for Hybrid Applications

03/03/2015 10:12 AM

I was doing some research and came across this new engine that is under development. It's a single stroke rotary engine that gets the efficiency of a diesel engine but with gasoline. It's called the Labralato engine. This engine looks like it could be a game changer in that it would allow hybrid cars to get over 100 mpg.

Put two of them together, back to back, make it a ½ stroke engine.

And a muffler (or two)

How is it lubricated? Fuel/oil mix?

Interesting. Hopefully they won't have seal wear problems like the Wankle.

Sorry, that would be Wankel.

The town and country types might have an issue with the noise and the recoil. Then again, the anti-hunting folk could scare all the wildlife off as well for their own protection.

Noisy little critter isn't it. I would hate to try and silence that, it would almost require some sort of noise canceling device besides a muffler. The energy pulse wave would be very hard to quiet down with just a muffler even with multi-chambers. But I could be wrong, I have been before and probably will be again.

Sounds like any 1 cylinder with an open exhaust.

Just a bit of bad PR on companies' behalf to release it with that audio - I am sure they will have mufflers for it already -

"New 1-stroke engine"

Looks like some variation on the Wankel or other pistonless rotary engine type.

(I was looking for a 'rotary diesel engine' example, but the Wanhel looks a lot like that, substitute the spark plug with a 'glow plug' for starting and you've got what I remember seeing for 'rotary diesel.')

Why keep working on 'gasoline' engines anyway? They only work over a narrow octaine range, and most 'octaine boosters'/'alternate fuels,' like ethanol, end up reducing the power density of the gas, requiring MORE fuel to be burned per mile traveled.

We should be working on true 'multifuel' vehicles, that could run on anything from vegetable oil to racing fuel to moonshine. or any blend thereof. With the computing power in the modern car, there could be real-time, stroke-to-stroke analysis of the fuel feed, with the engine being tweaked constantly by the computer to get the best eficciency from whatever combustible it is being fed. Make an engine like THAT to run the 'hybrid generator' when you're between plug-in rechargings, and NOW you've got a car that can work anywhere in the world.

such as the opposing piston engine of Ingo Valentin's support.
