All was top secret

For years we have been determined to make a completely new and  highly efficient engine. We new made designs, analyzed, made models, prototypes. There has been no news from us because we were never completely satisfied.

The Breakthrough

But now that has changed, there has been a breakthrough

Its time for us to move onward. Our design is easy to make, unique, has variable displacement (changes its size internally as it operates). And, in addition can switch to a wide variety of fuels within seconds. It naturally burns cleaner so is easier on our habitat.

Now, finally we are ready to move to the next plateau. Our engines will now be fine tuned, tested and readied for production. Our website has explained the many advantages of the Hefley Engine, better fuel economy and the ability to use alternate fuels are perhaps our most important features.

Moving On

We will now be increasing our staff which must include those experienced in the art of bringing our engine to its full potential. To complete its development our new engine like all new engine designs must be skillfully integrated and connected to its main on-board computer; This is an important step and is next on our agenda. Its time for us to move ahead with full power!

This Hefley X2 has all the features as the X1 but it also will adjust to a wide variety of fuels. It has adjustable compression ratio built in.

It can run on regular or high test gas, E85 ethanol, diesel, bio-diesel and other fuels still under development.
New Guide to our website

To make things easier to understand we created a new Guide to Hefley Engine that should make it easier to understand as well as offer you the latest news.  Be sure to visit it at:  www.CarlHefley.com 

It also has has direct links back her as well as easier access to the Secret...»
