The point of research project is research and production of key components of Guided explosion I.C. engine and afterwards prototype production of engine as whole. Mentioned main components are : 1.Runing mechanism, so main shaft, piston and connecting bearing between them. Conecting rod is eliminated in this construction and body is mainly monoblock type for this research. 2.Head with valve system, explosion chamber and injection electronics. 3.Charger what is actually good for any other engine. After research of main sub components, Engine as whole will be completed and used for research purpose. The main object of this research and engine at all is to use lean fuel/air mixture with very high compression ratio, over knock limit and very high expansion ratio through all power range of the engine. Explosions of F/A mixture will release all energy in TDP of piston , during explosion practicaly no or very little of CO , NOx or soot can be formed, so we expect very high engine efficiency, around 60% and very clean exhaust through all power range of this engine. For the first time we will research and use “The theory of variable volume of F/A Cloud in combustion chanber” to achieve these results in all engine power range.
Significance for science
Work on the project showed that explosion principle is the proper answer for the contemporary motors. It offers better efficiency and ecological results compared to Otto and Diesel cycle engines. High efficiencies which were about 47% during testing of the small motors and exhaust with practically no CO and smoke are the reasons to believe that such motors will reach the planned efficiency of about 60% and the ecological acceptability without the use of the catalizators.
Significance for the country
We can anticipate that such motors will enable production of cars with an average fuel consumption around 2.5 to 4 litres per kilometre, air-planes with 50% increased range. These motors will allow the usage of fuel without cancerous additives, will allow construction of cargo ships and yachts with significantly increased useful volumes. Besides, they will allow the production of fues from the biomass dust .
