Little Engine Delivers Lots Of Power
"It uses the same basic internal combustion technology as conventional engines," says Morgado. "It just packages it differently. The internal components are all there, but the configuration is different."
The MYT concept recognizes that cubic inches or displacement is what matters when it comes to power. By repositioning the combustion components in a circle, Morgado eliminates more than 80 percent of all parts found in a traditional engine. Gone are the traditional crankshaft, rods, pistons and cylinders.
Instead of multiple cylinders, Morgado's engine has a donut-shaped cylinder called a "torus". It's subdivided into eight segments by paddle-type pistons. These advance around the circular cylinder in a coordinated manner. The pistons are attached in two sets at 90 degree spacings to a central ring that, in turn, is connected to the timing mechanism and output shaft.
When combustion occurs in the leading set of pistons, they advance rapidly, expanding while the following set contracts. At about a 1/4 revolution, combustion occurs in the second set, and it expands, collapsing the first set of pistons. This alternating expansion and contraction provides a pumping action equivalent to a traditional 4-cyl. engine. The process is timed so each set of pistons completes two cycles of four combustion events per half revolution, or 16 combustion events per revolution. This compares to a conventional four-stroke engine that takes two revolutions to complete one cycle. For a four-stroke engine to compare in power events, it would need to have 32 cylinders.
In terms of displacement, in an MYT engine with a 3-in. diameter and a distance between piston dividers of 3.75 in., the ingested air volume per revolution is 424 cu. in. All this in a package the size of a 14-in. cube. To match that air volume with a conventional engine would require displacement of 848 cu. in., since each cylinder in a four-stroke engine only inhales every other revolution.
"An 8 cu. in. engine could power a full-size sedan, van or pickup, while a 14-cu. in. engine could replace a full size truck engine and would be equivalent to a 1,850 cu. in. engine," says Morgado.
He is hoping to get funding to build a pilot plant this year for limited production and further testing.
If he gets the financing needed to build his plant, and the concept machines prove themselves, Morgado hopes to use initial production to retrofit existing vehicles with the new engines. He says fuel savings alone will be great, and the MYT will never require an oil change.
"The MYT only has 11 moving parts and 15 parts total," he notes. "An 800-lb. engine in an SUV will be replaced by a 37-lb., 8 cu. in. MYT. Less weight and less friction with so many fewer parts will increase fuel efficiency. You could have better fuel economy in an SUV than a Toyota Prius."
Morgado reports that the U.S. military is interested in his engine design, as are car manufacturers working with hybrid designs. They would use the MYT to periodically recharge batteries. He also reports that he is now working on a two-stroke variation.
