OUR TECHNOLOGY
Most internal combustion engines operate on the Otto Cycle or the Diesel Cycle. They get an efficiency of 25% to 35%. Until recently, that was OK, because fuel was cheap, and power was king. CREED Engines has developed new technology. We started with the basic thermodynamic cycle, and a new vision - efficiency in engines is important - very important.

The General Cycle (and how it's different)At CREED Engines, our designs are based on a thermodynamic cycle called the General Cycle. The General Cycle was developed to create an idealized cycle of thermodynamic processes, including isothermal, isobaric, isochoric and adiabatic processes in a manner so that all currently known engine cycles, Otto, Diesel, Atkinson, Brayton, and the Dual Cycle may be described mathematically as special cases of the General Cycle. This provides a teaching tool for developing a more efficient engine.
How we are different
Our ApplicationsOur optimum efficiency engines are particularly applicable to large engine applications, such as stationary generation, ship engines, truck engines and large off-road machinery. When one thinks of an efficient internal combustion engine, the natural inclination is to think of a car getting exceptional gas mileage. But our engines are not particularly well suited for car engines, because our engines are best run at constant RPM and generally have lower specific power than the personal transportation market finds acceptable. But large engines - that's where we shine. Of particular note is stationary cogeneration facilities using renewable fuel to produce combined heat and electrical power.

Fuels for Our EnginesOur engines can run on practically any liquid or gaseous fuel. Diesel, gasoline, natural gas, and even hydrogen. We are particularly interested in renewable bio-fuels. Remarkably, we have noted that our engine runs even better on renewable, easily producible fuels such as an Alcohol Fuel Blend.
The Search for Engine EfficiencyWe analyzed multiple factors in developing the specific features that we incorporated into our optimal efficiency engine. Using the basic efficiency formula of the General Cycle, we saw that there were bands of exceptional efficiency when a certain sequence of processes was employed. We then used two different types of computer modeling to look at design fundamentals that increased efficiency. We developed a practical design in which these processes could be carried out. The result was an engine that exceeded 60% efficiency in converting fuel to shaft power. For years the 60% figure has been touted as the holy grail of engine efficiency. But until now, it has not been achieved. Now, we can tell an engine designer exactly how to build an engine that meets their requirements of power and size, and how to get the peak efficiency for their application. We patented our technology. (U.S. Patent Number 11,454,165, other patents pending) But the world really needs this. We're willing to share, so let us know if you're interested.

The CREED Engines Story
Ernie Rogers is a brilliant theoretical physicist. He's been thinking for a long time about ways to make internal combustion engines more efficient. Glen Collett is a practical inventor, a technical writer, and a computer nerd. We've known each other for over 50 years. "What do we work on?" Ernie suggested a highly efficient engine - and CREED Engines was born.
(By the way - "CREED" stands for Collett Rogers Efficient Engine Development)
