摘要： In a cylinder with a cylinder surface receiving a piston the cylinder surface has at least two zones with different oil retention capabilities; sectors having a relatively high oil retention capability are disposed in areas of the cylinder surface which are subjected to relatively high radial pressure forces while the other areas have only a relatively low oil retention capability. The oil retention sectors have a width which changes over their axial length so as to provide only a surface area with increased oil retention capability as needed to accommodate high radial pressure forces of the piston while the rest of the cylinder surface has a low oil retention capability to eliminate unnecessary oil consumption and engine emissions.

摘要： A process for intermittent control of a cyclically operating internal combustion engine wherein, in the succession of working cycles, working strokes are skipped--in approximately uniform distribution--and the number of skips is varied in dependence on the load. Fuel is fed in a controlled fashion only to the nonskipping working chambers of the internal combustion engine independently of the load in a constant quantity optimal for consumption. For a sensitive power distribution, especially in the low load range, the number of skips is varied chronologically at least approximately randomly and independently of the speed, i.e., the temporal density of the working strokes is varied. This can be accomplished by setting differently finely staggered firing patterns or by a stochastic ignition setting.

摘要： A multicylinder internal combustion engine, especially a self-igniting internal combustion engine, with supply ducts leading to the cylinders which supply ducts emanate from a common fuel supply chamber with the ducts being supplied with a fuel-gas mixture. The fuel-gas mixture is present in a mist form in the supply chamber with the fuel, with a substantially identical droplet size, exhibiting a droplet diameter at which a flow characteristic is obtained for the droplets in the ducts leading to the cylinders which is respectively at least approximately identical to the flow characteristic of the gas. The fuel is fed to the common supply chamber continuously by way of an injection device with the premixed fuel-gas mixture, which is at a pressure elevated with respect to the pressure level in the supply chamber, exiting from the injection device at a speed of sound with atomization of its proportion of fuel, on account of a pressure jump at a cross section of the discharge orifice of the injection device.
