Abstract (en)
[origin: WO8802065A1] During starting and, possibly during partial loading, the diesel internal combustion engine operates in a so-called partial mode, meaning that several cylinders (7 to 12) act in compression without a fuel feed and feed compressed air to the drive cylinders (1 to 6). For example, the compression cylinder (8) is connected to the drive cylinder (5) by a pipe (13) independent of the usual admission and exhaust pipes, which comprises, at one of its ends close to the compression cylinder (8), a distribution valve (2) which can open in the partial mode, and at its other extremity near the driving cylinder (5), a receiving valve (23). Each of the receiving valves (23) is combined with a device enabling arbitrary opening of the respective pipe (13) in the direction of the compression cylinder (14), in other words these devices control the opening of the pipes (13) during the thrust travel of the corresponding drive cylinder (16). This enables recycling into the compression cylinders (7 to 12) of the exhaust gases from the drive cylinders (1 to 6), as well as a temperature rise in the compression cylinders in the partial mode of the diesel internal combustion engine.
