Inlet and exhaust control in four-stroke internal combustion engines with DZM-D (rotary cylinder engine double nozzle)

摘要

- Field of application: The invention has applications in reciprocating piston engines, especially in four-stroke internal combustion engines. These include four-stroke spark ignition engines, diesel engines, multi-fuel engines, etc. - Operating principle of the DZM-D: The inlet and exhaust control in the rotary cylinder engine double nozzle is characterised in that, due to the reciprocating movement of the engine piston, the associated rotation of the crankshaft is converted by way of a gear fixed thereon in order to drive the rotary movement of the engine cylinder. Due to rotation of the engine cylinder the inlet and exhaust of the gas mixture are controlled by way of four opening ports. Due to the transmission ratio of the gears, 1 rotation of the engine cylinder and, with 2 inlet and exhaust nozzles, 2 ignitions of the gas mixture are performed for 4 revolutions of the crankshaft. <IMAGE> - Advantages of the invention: - Simplified engine construction due to the absence of valves, camshaft, timing chain - More rapid and more complete mixture charging possible due to 2 inlet nozzles - Attainment of the absolute timings in charging and discharging of the combustion chamber due to opening ports - Increased crankshaft revolutions - Engine power increase - Due to rotary movement of the cylinder an improved swirling of the ...
