Our team is currently working on the development of a new concept concentric rotary engine. The technology we are developing is a novel approach of the internal combustion engines (ICEs) and, based on the CFD modeling and analysis, it is offering the following achievements (compared to ICEs of similar power):
1. up to 5 times smaller in size
2. up to 6 times reduced weight
3. up to 19% more efficient than Otto cycle, using the Atkinson cycle
4. better quality of fuel emissions
5. less noise during operation, since it has no reciprocating parts and no eccentricity.
We also expect that
1. the building and maintenance costs will be significantly lower,
2. the lifespan of the engine should be significantly higher than existing commercial technologies.
Our technology is providing both direct and indirect benefits and solutions to the industry and end-users. Beyond the ability to reduce the cost of building and maintaining ICEs, the reduced weight and volume of the engine can mean:
• decreased CO2 emissions,
• new vehicle designs and less aerodynamic resistance,
• added space for transferring goods,
• simpler maintenance routines,
• environmentally friendly
• less noise, which makes it the best solution for applications where low NVH is desired
• an ideal range extender
Our engine can be applied in all transportation industries like locomotive, automotive, aerospace, marine, power generation, mineral extraction and applications where the noise is a matter of significant importance (e.g. small production units of electrical power at remote places, larger units close to residential regions e.t.c.)
The innovation of our technology is already proved by its patents (in 7 European countries, U.S.A., Australia, Russia, China and pending in India) and the first prize won in the HIGE2010 contest (Honda Initiation Grant Europe in the year 2010), where it was characterised as “... the most exciting idea of the year”. In addition, the feedback we receive from academic and industry experts is excitement and interest for involvement.
The applicant and owner of the patents is Savvas Savvakis who is also the project leader. Apart from the Honda Grant during his PhD, he won also an award from the Technical Chamber of Greece because he had the third higher Diploma-degree for the graduation year 2000-2001 and a scholarship from the State Scholarship Foundation (in Greek ?.?.?.) because of his academic excellence for the academic year 1996-97
The SARM project team is consisted by 8 permanent members (3 in business and 5 in R&D), and a number of supporters from the academic world (engineers with Master and PhD on engine development) and the industry.
Currently, our focus is the completion of the 3D CAD model so as to be able to proceed with building the prototype model of the engine. Our next steps, involve the continuous optimisation of the engine and all technologies found in it, as well as its commercial promotion.
