Tiago Costa, MIT Portugal EDAM/LTI PhD Student at Universidade do Minho, is part of the team competing at the Create the Future Design Contest with a high efficiency engine, Hyper4.
Tiago Costa, Jorge Martins and Francisco Brito - both professors at UMinho teamed up with Bernie Bon an american engines enthusiast. Two American investors supported the concept disclosure at conferences and supported the US patent record. A third element should soon fund the production of the first prototype.
Hyper4, is built from standard stock materials and no castings need be employed in its manufacture, saving both time and money while reducing waste. Nor does it incur the use of exotic materials or any new engineering disciplines. The Hyper4 improves the fuel efficiency of internal combustion engines by up to 75%, approaching 50% brake thermal efficiency in a unique, compact axial design that is both straightforward and inexpensive to manufacture. Unlike a standard inline engine, the incorporation of constant volume combustion, variable compression ratios and over expansion is virtually effortless.
“The main characteristic of this engine, which allows us to implement all the aforementioned innovations, is the mechanism we developed to change piston movement”, Tiago Costa reminds us.
In the framework of Tiago Costa’s PhD project, several other strategies to harness energy losses are being researched, particularly engine cooling. “We are working on the possibility of internal cooling by injecting water onto the hot engine parts. By using the steam created during the internal cooling process, we are adding a steam engine to the internal combustion engine, which adds pressure onto the pistons, allowing more work to be produced from the same amount of fuel. We are using the extra enthalpy from the exhaust gases and the generated steam, which otherwise would be lost within the hot exhaust gases and through the engine’s radiator”, Jorge Martins refers.
