Axial Vector Engine (was DynaCam Engine.)

So, several years ago a coworker Jesse pointed me to an engine design I thought was very nifty, called DynaCam. It promised to revolutionize ICE performance. But never got developed. No substantial news from the company. So sad, another good idea dead in the water.

I searched for it again today, and found AVEC, a company apparently created solely to develop the technology. They have revamped the design, and are marketing a family of electricity generators. Not so bad.

There are some weaknesses though. The companies website is less than friendly and lacking useful information. Also, there’s many investors links about this company, and its… turbulent history, including key personnel. Doesn’t raise my faith much in them completing their goal.

It is really nifty technology. Imagine a double-ended piston, sitting in to cylinders at each end. This entity alone could act as a reciprocating linear engine, with energy savings over most Flat or V piston layouts. Of course the energy is hard to capture. But, put six of these double-ended pistons together, parallel to each other, forming a regular hexagon in its cross section. All of these are combined with a sinusoidal cam shaft, which ties into a central axle.

Yea… I wish I could easily draw CAD pictures to visualize this… but alas I am not skilled as such. I also tried to use the Wayback Machine to search for it, but the animation is not to be found. You can checkout aspects of the old webpage though.

Anyway, the results of prototypes have shown the dramatic performance differences. This is the best summary I can find so far. Per HP: it is lighter; produces more powerful torque, more efficient fuel usage, and less pollution; and can utilize a variety of heavy fuels. Quite a revolutionary product… if it can be brought to market.

  1. It seems to me that this is a design that could be the answer to a number of problems in producing en economical, simple, light weight, low RPM high torque and efficient engine. This is a relitive old design so patent should be no object.
    A lot of money has been spent on gear reduction systems and their inherant compexities. It seems to me that if all the time, effort and money that has been spent trying to make the wankel viable had been put into this engine we would have something worthwhile.

  2. I think it could be an efficient engine, probably could be more effecient than a wankel because of the way the sealing surfaces work. also torque should be alot better as well if an inproved transmission would be derived for it. I can only guess that it would really work well with a G.E.E.T processor if a good method of preserving the proper air mixture at any rpm is possible in a mechinacal means. I saw that some were turbo charged and intercooled that makes it more of a challenge to install a G.E.E.T processor.
    I suppose that alot is up to the development aspect and what is seen as affordable.
    It does seem like alot of experimentation goes into the cars that everyone drives already, and people do tend to work on them for fun sometimes so I don’t know why it hasn’t been tried. Maybe it wouldn’t have a good artificial obsolences point.

  3. Thinking a common rail injection systeem like that which is used on current diesel engines coupled with a super charger should take care of the air fule mixture under most use.

  4. has hydrogen been tested as a fuel on these motors yet.
    if it has been, what has been the results for power and torque.
    can you show the water cooling jackets in the schematics of details.
