OUR TECHNOLOGY
|
Most internal combustion engines operate on the Otto Cycle (cars that take gasoline) or the Dual Cycle (trucks that use Diesel fuel). They get an efficiency of about 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 science (the thermodynamic cycle), and a new vision - efficiency in engines is important - very important.
We believe that focusing on both high-efficiency engines and appropriate renewable fuels in tandem provides the best direction to address the fossil fuel problem. You can find the details on our Technical Page. |
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 adiabatic, isobaric, and isochoric 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 learning tool for developing a more efficient engine.
How we are different
Our ApplicationsOur optimum efficiency engines are especially useful in 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 in larger engines - that's where we shine. One area of application for our engines is heavy trucks such as freight haulers and off-road equipment such as used in farming and mining. Another application 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 biofuels. Remarkably, we have noted that our engine runs even better on renewable, easily producible fuels such as a Renewable Alcohol Blend Fuel.
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 can exceed 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 engine designers 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) The world really needs this. We are willing to share, so let us know if you are interested.
Environmental BenefitsHigher efficiency in an engine does not just mean lower cost for the fuel to get the job done. It also means less fuel that must be produced and transported. Less fuel used means less exhaust and less pollution. And with renewable fuels it means net-zero-carbon emissions.
