Abstract (en)
[origin: DE19514571C1] For known structural reasons, there are so far no fuel-injected piston combustion engines operating at pressure ratios higher the 1:21. It is the purpose of this invention to produce a fuel-injected piston combustion engine operating at pressures from over 1:25 to about 1:40 with a simultaneous pressure drop in the exhaust gases to 1 bar. The Otto-cycle operating mode achieved provides very high efficiencies, resulting in fuel consumptions of under 80g/HPh. As will be seen from fig. 2, this aim is achieved by a design with a centrically rotating cylinder block (10) and a cylinder fitted centrically therein, in which a piston (15) connected to the uncranked mainshaft (13) by a rigid connecting rod (136) rotates in the big-end bearing (14) and the rotation speed ratio between the cylinder block and the mainshaft is 1:1 with no intermediate gearing, so that only deceleration and acceleration forces act on the cylinder block. Production of a fuel-injected piston combustion engine, mainly for transport (automobile) drives to reduce CO2 emissions.
