A NOVEL DESIGN OF THE COMBUSTION ENGINE FOR IMPROVEMENT OF THE EFFICIENCY AND DURABILITY

For the purpose of the improvement of the efficiency of the combustion engine, the new solution which links in the advantage of the engine with the spark-ignition and the diesel engine is proposes. The creature of the solution consists in the realization the process of the combustion at the constant of the volume combustion chambers. It is realized with a piston stand during the period of combustion process. This permits on maximum pressure increasing and average indicated pressure. Advantages of this solution are self-evident. The enlargement of the efficiency is obtained, and finally- decrease of fuel consumption. Whereas at such itself average indicated pressure, the of maximum decrease of appears. This maximum pressure decrease causes decrease of mechanical loads of most essential engine parts, for which the pistons belong. The novel design of the engine is In order to reduce the thermal loads on the piston and the negative effects of thermal shocks, the novel construction based design was proposed, where during the time when the thermal loads are the most severe, the mechanical loads are isolated from the inertial loads and the inertial loads are non existent. Besides the reduction of the thermal loads additional gains in overall efficiency were obtained as the result of the combustion process with the piston stopped. That system forms the part of United States Patent No. 6,481.393 B1. Thermal shocks are reasons for high temperature gradients occurring in materials of engine components and sets
