Patent DE-3406732-A1 (DE)
Title: Operating process for reciprocating piston internal-combustion engines and combustion engine for this
Inventor: BENNEDIK REINHARD
IPC: F02F1/24
Filed: 1984-02-24
Abstract: The invention relates to an operating process for reciprocating piston internal-combustion engines, in which ignition occurs either by means of a special device or by means of spontaneous ignition. Unlike the four-stroke process, in the six-stroke process the crankshaft-cam shaft transmission ratio must be 1:3. A working cycle therefore does not correspond to 720 DEG  but 1080 DEG  crankshaft angle; the elevation curve and spread of the cams for the valve control must be correspondingly adjusted. Induction occurs on the 1st stroke, compression on the 2nd stroke, on the 3rd stroke a partial amount of the fuel needed for combustion arrives, compression occurs again on the 4th stroke, on the 5th stroke recombustion takes place with the remainder of the fuel (in this case air fractions must also be fed from a prechamber or auxiliary chamber to spark ignition engines), exhaust occurs on the 6th stroke. In the six-stroke process the proportion of pump work is reduced. By dividing the combustion between two strokes (3rd and 5th stroke), even running and a reduction of the pressure peaks and the mechanical and thermal stresses are achieved on the one hand with, however, a prolonged and more intensive combustion process at lower temperatures on the other, thereby reducing pollutant emissions. <IMAGE>
