Definitions
- the invention relates to an internal combustion engine with at least two groups of cylinders, with at least one exhaust gas turbocharger, with an intake system, an exhaust system with an exhaust line in each group and an exhaust gas recirculation system with at least one exhaust gas recirculation line which branches upstream of the exhaust gas turbine of the exhaust gas turbocharger from the exhaust system
- an internal combustion engine with two cylinder banks is known, one exhaust pipe leading to the exhaust gas turbocharger per cylinder bank.
- the exhaust gas turbine is designed with two separate inflow ducts which are shielded from one another in a pressure-tight manner, one inflow duct communicating with an exhaust gas line from which a return line of the exhaust gas recirculation branches off.
- the second exhaust pipe of the second cylinder bank opens into the other inflow channel.
- the exhaust gas turbine has a variable turbine geometry for controlling the exhaust gas back pressure. In certain engine operating areas, however, this arrangement does not allow excessively high exhaust gas recirculation rates to be achieved.
- DE 25 27 871 describes an internal combustion engine with an exhaust gas turbocharger, in which an adjustable bypass line connects the pressure side of the compressor to the exhaust system and opens there in a region of low pressure.
- the bypass line opens into the mixing zone of a pulse converter designed as a vacuum zone. Air is led from the pressure side of the compressor to the turbine of the exhaust gas turbocharger via the bypass line.
- US Pat. No. 3,786,630 A discloses an internal combustion engine with cylinders arranged in a V-shape, the exhaust gas lines of each row of cylinders opening into an exhaust line.
- the exhaust gas lines open into a pulse converter upstream of an exhaust gas turbocharger arrangement with two turbo blowers. The efficiency of the exhaust gas turbine arrangement can be increased by this arrangement.
- an exhaust pipe system for a turbocharged four-stroke internal combustion engine is known, the exhaust pipes of two groups of cylinders each opening into a shock pipe, which are connected to one another via a connecting line with a narrowing cross-section.
- Each of the two shock lines leads into a gas inlet of an exhaust gas turbine.
- the object of the invention is to increase the exhaust gas recirculation rates in the simplest possible manner in an internal combustion engine of the type mentioned at the outset.
- a variable turbine geometry or a bypass valve is provided for controlling the exhaust gas back pressure in front of the preferably single-flow exhaust gas turbine and / or the supercharging pressure generated by it. It is particularly advantageous if a pulse converter is arranged upstream of the exhaust gas turbine in the exhaust system, into which exhaust manifolds of the groups of cylinders open, the exhaust gas recirculation line preferably branching off from the exhaust system upstream of the pulse converter.
- the pulse converter prevents mutual interference of the pressure pulsations in the individual exhaust manifolds.
- a check valve opening in the direction of the inlet system is arranged in each exhaust gas recirculation line.
- the flow path for the recirculated exhaust gas is only released if there is excess pressure in the exhaust system.
- the exhaust gas is returned to the intake system via at least one Venturi nozzle.
- the exhaust gas turbine can either be equipped with a variable turbine geometry or with a blow-off valve in order to enable optimal operation with regard to exhaust gas recirculation rate and boost pressure build-up.
- High exhaust gas recirculation rates can be achieved, in particular, by the pulse converter arranged upstream of the exhaust gas turbine in the exhaust line, since all upstream exhaust manifolds from the groups of cylinders receive the same outflow conditions and a mutual interference of the exhaust gas pressure pulses in the individual exhaust manifolds is avoided by the pulse converter.
- the exhaust gas turbine can be designed as a simple, inexpensive, single-flow turbine, which keeps the manufacturing expenditure extremely low. Due to the single-flow design with a single blow-off valve (waste gate) or with variable turbine geometry (VTG), the control and regulation expenditure can be kept within limits.
- the invention is explained in more detail below with reference to the figure.
- the figure schematically shows an internal combustion engine 1 according to the invention with an intake system 2, an exhaust system 3 and an exhaust gas recirculation system 4.
- An exhaust gas turbocharger 5 is provided for charging.
- the internal combustion engine 1 has two groups 6, 7 of cylinders 19, 20 formed by cylinder banks, the exhaust pipes 8, 9 of which each open into an exhaust manifold 10, 11.
- the two exhaust lines 10, 11 lead to a pulse converter 12, from which a common exhaust line 13 emerges, to which the single-flow exhaust gas turbine 24 of the exhaust gas turbocharger 5 is connected.
- An exhaust gas recirculation line 14a, 14b of the exhaust gas recirculation system 4 branches off from each exhaust line 10, 11 and leads to the intake line 15 of the intake system 2 and further to the intake manifold 16, which is connected to the individual cylinders 19, 20 of groups 6, 7 via intake channels 17, 18 is.
- An exhaust gas recirculation valve 23a, 23b, an exhaust gas recirculation cooler 25a, 25b and a check valve 26a, 26b are arranged in each exhaust gas recirculation line 14a, 14b.
- the exhaust gas turbine 24 can either be equipped with a variable turbine geometry or with a blow-off valve 22 for blowing the exhaust gas turbine 24 around.
- the combination of the pulse converter 12 with the exhaust gas turbine 24 equipped with a bypass valve 22 or with a variable turbine geometry means that the exhaust gas recirculation rate can be increased significantly compared to a system without a pulse converter and a double-flow exhaust gas turbine with only one bypass valve, with extremely little manufacturing effort.
- references used in the subclaims indicate the further development of the subject matter of the skin claim through the features of the respective subclaim; they are not to be understood as a waiver of the achievement of an independent, objective protection for the characteristics of the related subclaims.
