Multi-valve piston engine with external combustion and inner pressure cooling system as well as method for controlling operation of the piston engine with external combustion and inner pressure cooling system

摘要

The subject-matter of this invention is thermal multi-valve piston engine (TMPE) of external combustion, characterized in that the head (3) of the engine, next to standard inlet valve (4) and outlet valve (7) connected hydraulically with heater (9) and cooler (10) respectively, is fitted with at least one extra inlet valve (5), through which the cylinder interior is hydraulically connected to cooler (10), and at least one extra outlet valve (6), through which the cylinder interior is hydraulically connected to heater (9), furthermore, with regard to the adopted parameters of engine operation, the function of compressor or pressure pump compressing the agent directly before feeding it to heater (9), is performed by the same cylinder (1) capped with head (3), with piston (2) inside. The another subject matter of invention is a method of control of thermal multi-valve piston engine (TMPE) operation, characterized in that the isobaric filling of cylinder (1) from heater (9) during the first phase of the working stroke, with heated agent in gaseous form, with temperature, pressure and specific volume higher than critical for that agent.
