Definitions
- the invention relates to an internal combustion engine having a plurality of cylinders, with an intake system and an exhaust system, wherein at least one cylinder is fired and operated as a compressor and exhaust gas is traceable in the unfired cylinder. Furthermore, the invention relates to a method for operating this internal combustion engine.
- a multi-cylinder diesel engine with low compression ratio which operates during startup and optionally at partial load in so-called split operation, with some cylinders operate without fuel supply as a compressor and the working cylinders operate as compressed air.
- the compressor cylinder is connected to the engine cylinder via a line independent of the usual intake and exhaust pipes, which has at its one end in the vicinity of the compressor cylinder a aufêtbares in split operation donor valve and at its other end in the vicinity of the engine cylinder a receiver valve.
- Each of the receiver valves is combined with a device for random opening of the respective associated line in the direction of the compressor cylinder, wherein the control of the lines is carried out by the devices during Ausschubhub the associated engine cylinder.
- the object of the invention is to allow the simplest possible way in an internal combustion engine of the type mentioned in all engine operating points, a high amount of recirculated exhaust gas.
- this is achieved in that the inlet side of the unfrozen cylinder is connected to the outlet system, preferably between outlet header and an exhaust gas turbine, and the outlet side of the non-rooted cylinder is connected to the inlet system, preferably between a compressor and an inlet header, preferably between Outlet side of the unfired cylinder and the intake system, an exhaust gas recirculation cooler is arranged.
- an exhaust gas recirculation cooler is arranged between the exhaust system and the unfired cylinder.
- the outlet side of the cylinder operated without an impeller, downstream of the exhaust gas recirculation cooler can be connected to the inlet side via a bypass line.
- control times of the valves of the unfired operated cylinder can be operated according to the 2-stroke principle.
- particularly high amounts of recirculated exhaust gas can be achieved. It is thus sucked once per crankshaft rotation and discharged compressed gas.
- a second exhaust gas recirculation cooler upstream of the unfired cylinder can be arranged.
- the FIGURE schematically shows an internal combustion engine 1 according to the invention with a plurality of cylinders 2, which has an inlet system 3 and an outlet system 4.
- an exhaust gas turbine 12 of the exhaust gas turbocharger 6 is arranged downstream of the exhaust manifold 10.
- the inlet side 13 of the unfired cylinder 2a stands in this case via a first exhaust gas recirculation line 14 with the outlet System 4 in connection, wherein the first exhaust gas recirculation line 14 branches off between the exhaust manifold 10 and the exhaust gas turbine 12 from the exhaust system 4.
- From the outlet side 15 is a second exhaust gas recirculation line 16, which opens via a charge air cooler 7 between the compressor 5 and the intake manifold 8 in the intake system 3.
- an exhaust gas recirculation valve 18 may be provided in the second exhaust gas recirculation line 16 before entering the intake system 3, and a bypass line 19 branching off from the second exhaust gas recirculation line 16 and leading to the inlet side 13 of the unfired cylinder 2a.
- an exhaust gas recirculation valve 21 may also be provided in the first exhaust gas recirculation line 14.
- a crankshaft is indicated.
- a portion of the exhaust gas mass flow is taken from the exhaust system 4 between the exhaust manifold 10 and the exhaust gas turbine 12 and fed to one or more unfired cylinders 2a, compressed there and then passed through at least one exhaust gas recirculation cooler 17.
- the cooled exhaust gas is then admixed with the air mass flow of the intake system 3.
- the unfired cylinder 2a is driven by the crankshaft 20.
- the control times of the unfired cylinder 2a are adjusted so that the highest possible amounts of exhaust gas can be recycled. It is particularly advantageous if, during two crankshaft revolutions, two intake strokes and two exhaust strokes of the unfired cylinder 2a take place, the unfired cylinder 2a thus being operated in a two-stroke process.
- the exhaust gas is supplied and discharged via existing ducts.
- an unillustrated further exhaust gas recirculation cooler can also be arranged in the first exhaust gas recirculation line 14 between the diversion from the exhaust system and the inlet side 13 in order to increase the cooling of the recirculated exhaust gas and thus to improve the degree of filling.
- the unfired cylinder 2 a may be designed with a different lifting and / or compression ratio than the fired cylinders 2.
- the charging of the internal combustion engine 1 may take place in one or more stages. The use of exhaust and storage elements is possible.
- the system allows a high flexibility in the exhaust gas recirculation rate, whereby the exhaust gas recirculation operation by the exhaust gas recirculation valves 18 and 21 and the bypass line 19 can be easily controlled.
