Spain is Living in 2050? Revolutionary 1 Stroke INNengine Analyzed

Update of Jul 16th post:

What if you were to pair this lightweight engine with the lightweight electric engine in a hybrid design?



A lot of torque and horsepower isn't needed in a basic car. Acceptable performance would be sufficient if the result could be an affordable and sensible automobile.

Good things might be possible in small packages. Let's say that you reduced the battery capacity to minimize the weight of the batteries. True, it would necessitate frequent use of the range extender, but who cares?

The idea would be efficiency. Electric engines can start on a load, whereas an internal combustion engine cannot. It only takes 20 horsepower or thereabouts to cruise at highway speed. Most of the time, you just don't need all that much horsepower. If you had an engine that could produce a lot for short periods, that would be ideal. Especially if it didn't weigh much.

The upper range of today's batteries would yield a kwh for every 8.3 lbs of battery. If the battery is limited to 5 kwh, that would weigh less than 50 lbs for the battery. You could put together a decent drive train for a modest amount of weight. Add a generator and an ultracapacitor. Surely you could put it all together with decent performance for not that much weight. A sub compact internal combustion engine type car could be about a ton. Perhaps you could do it this way for about that much.

Less weight means less fuel expenditure, too.

There's a lot of nerdy stuff here...

Bottom line seems to be that to get sufficient torque, a supercharger is needed. That's because of low-end torque.

An idea popped into my head while watching this. What if you were to use this engine as a range extender for a battery pack? Batteries are way too heavy. If you were to include this small, lightweight engine to a generator, then it could recharge the battery pack on the fly. Shoot, you may be able to downsize this engine even more than that is. In order to cruise at highway speed, it is only necessary to have 20 or so horsepower.

The most power needed is to get moving. To keep moving doesn't need nearly as much power. That's why it could be useful for range extension. If the thing were small enough, it would presumably need not that much power to generate the necessary power to recharge the battery pack, or to take over electrical generation, or both.

The light weight design would save weight from all those batteries. It would need some support mechanisms, such as a generator. Also, a tank for fuel needs to be included. Again, these may be small enough to keep some weight savings, so the replacement of batteries doesn't get you back to a too-heavy vehicle. A little further on the video reveals that there is a 125 CC engine of this type. It generates 28 horsepower. Cool!

Advantages: Simplicity, low-weight, and compact design.

An interesting concept... So here's the video...
