Technical feasibility


1 Has the R & D result been tested?


The following question is replied according to the reply in question 1


If yes


1a In what mode has the result been tested?

•              Prototype

•              Pilot Application

•              Alpha/BETA testing


Invented by the company in 2005, the springless valve system for engines with internal combustion lowers the energy normally consumed by the standard valves and springs, thus reducing wear and helping reducing the environmental footprint. The technical decision leads to increased durability and life of the system’s mechanism, as a result of removing the springs, yet another major disadvantage of the ordinary valve system. The valves don’t have to be adjusted or fixed with the time being used, which is saving expenses to the owner of the automobile. A major advantage of the development remains the fact, that the system could be implemented to an engine, simply substituting the ordinary valves/spring system, without changes and amendments in the current production lines.

Shortly after the invention a working prototype was created and fitted to a standard internal combustion engine. Evaluation results measured lowered rotation resistance, noticeable decrease in the raw materials, necessary for manufacturing. The improvement of these two characteristics, combined with the simplified design resulted fuel economy and significant reduction of the environmentally dangerous emissions.



1b. Please describe and discuss the testing results
Extensive testing of the prototype confirmed the research results – over 30% decrease in the raw materials, necessary for manufacturing, over 13.5 times decrease in the rotation resistance. The system testing data showed a gained improvement in horsepower, torque and reduced emission, also resulted in 5-8% fuel economy.



SECTION 2: Current Stage of Development


2a To what extent does the development team have technical resources for supporting the production of a new product? (Researchers, human resources, hardware, etc. )
The research team has managed to develop and create a working prototype of a springless valve system for internal combustion engines. The team has the knowledge and the abilities for implementation of the invention in small scale production, as well as for necessary amendments and correction, which may arise, due to specific client’s requirements. The existence of a small steel machining factory makes easier the preparation and organization of a pilot batch, necessary for organization of further large scale production.



2b What are the technical issues that need to be tackled for full deployment, if needed?
The product is fully developed and completed at a stage of prototype. All tests and practical evaluation have proved excellent results, leading to significant decrease in fuel consumption and lowering environmentally harmful emissions. Next challenge would be the manufacturing of a pilot batch for testing and evaluation for organizing of large scale production.



2c What additional technical resources are needed for the production of this new product?
For starting a pilot batch production the company will need as minimum universal steel milling equipment, such as lathe, universal milling machine and CNC controlled milling center. The necessary manufacturing areas could be determined at approx. 700 – 1000 sq. m. for the initial stages of production. The company has a potential for developing an engineering team itself, so it will need additional technical staff (operators) and mechanics.


2d Overall assessment of the current stage of technical development.
At the current stage the springless valve system for internal combustion engines is fully developed as a working prototype, ready for implementation and tailor made to the customer’s requirements.  The prototype have been tested and ready for implementation.





SECTION 3: Deployment

3a Define the demands for large scale production in terms of
  • Materials
The materials, needed for manufacturing the springless valve system, are conventional, well-known and widely available alloys. The reduced use of raw materials make the product cost effective and relatively easy for implementation even is large scale production.




  • technologies, tools, machineries
For starting a small batch production the company will need conventional universal metalworking equipment, consisting of lathes, universal milling machines and a metalworking CNC controlled turning center for a future broadening of the production.




  • Staff effort
The company has the abilities to develop and provide engineering controlling staff. Metal processing machines operators and locksmiths will be needed for manufacturing of the product, as well as CNC trained operators. Mechanics/fitters for the final stage of production.






SECTION 4: Overall Assessment


1 What is you overall assessment of the technical feasibility of the research result?
The springless valve system for is fully developed and working. All evaluation and test programs have proven its abilities to decrease significantly fuel consumption in a standard internal combustion engines by 5-8%, thus noticeably lowering the environmentally harmful emissions. The technical decision helps facing one of the biggest nowadays challenges – the environmental pollution, as well as also provides means for nearly 30% reduction of the materials (aluminum), necessary for manufacturing, compared to the currently highly implemented in the automotive industry standard valve systems with springs.
