Definitions
- the invention relates to an internal combustion engine with a suction line for supplying the intake air to the individual combustion chambers, with an exhaust pipe for removing the exhaust gases from the combustion chambers and with a connecting the suction pipe and the exhaust pipe Exhaust gas recirculation line, wherein in the exhaust pipe a the Return of exhaust gas through the exhaust gas recirculation line controlling Temperature sensor is arranged.
- Such an internal combustion engine is known from DE 199 12 317 C2.
- a central electronic control device provided in addition to the temperature the amount of fresh air supplied, the temperature of the recirculated Exhaust gas also the temperature of the total supplied Mixture quantity determined.
- Such exhaust gas recirculation control is also referred to as EGR regulation.
- the invention is based on the object, an internal combustion engine with an EGR control according to the preamble of claim 1 create that without electronic control device, without control motors and manages without electrical measuring sensors.
- the temperature sensor is a mechanical thermocouple whose temperature-dependent deflection is an exhaust flap mechanically controls is an EGR control without electronic control device, without control motors and without electrical measuring sensors created.
- This EGR regulation is based solely on the Controlled variable exhaust gas temperature, which however is directly load-dependent.
- Such EGR control according to the invention is in particular for such internal combustion engines interesting, which does not have electronic Have engine governor, but where the injection pump of a mechanical regulator is controlled.
- thermocouple in the exhaust pipe is in Flow direction before the exhaust gas removal of the exhaust gas recirculation line arranged.
- the exhaust valve arranged in the exhaust gas recirculation line, preferably before Entry into the intake line.
- the exhaust valve in the exhaust pipe in the flow direction behind the branch arranged the exhaust gas recirculation line. This leaves the exhaust gas recirculation line always connected to the suction line. Will through Close the exhaust flap, the exhaust back pressure in the exhaust pipe increases, more exhaust gas is returned to the intake manifold accordingly.
- thermocouple is a bimetallic spring or a Memory spring.
- the internal combustion engine is a self-igniting Internal combustion engine.
- Figure 1 shows a section of an internal combustion engine 1. Im Only the parts relevant to the invention will be described below.
- the intake air passes via an intake passage 2 via not shown here Gas exchange valves in the individual combustion chambers 3 of the internal combustion engine 1.
- the intake pipe 2 adjacent is an exhaust pipe 4 provided, via which the exhaust gases from the combustion chambers. 3 are also removed via not shown gas exchange valves.
- an exhaust valve 7 is arranged, with the Passage cross section of the exhaust gas recirculation line 5 is adjustable.
- thermocouple 6 As a temperature sensor.
- the thermocouple 6 is here in the exhaust pipe 4 in the flow direction before the exhaust gas removal 8 the exhaust gas recirculation line 5 is arranged.
- a thermocouple 6 comes preferably a bimetallic spring or a memory spring in question.
- to Control of the exhaust valve 7 is the temperature-dependent mechanical Deflection of the thermocouple 6 with the exhaust valve 7 so connected to the exhaust flap 7 by the deflection of the Thermocouple 6 is controlled or controlled.
- FIG. 2 shows an alternative embodiment of an EGR control, in an exhaust flap 7 in the flow direction behind the exhaust gas removal 8 of the exhaust gas recirculation line 5 is arranged.
- the intake air passes via an intake passage 2 via not shown here Gas exchange valves in the individual combustion chambers 3 of the internal combustion engine 1.
- the intake pipe 2 adjacent is an exhaust pipe 4 provided, via which the exhaust gases from the combustion chambers. 3 are also removed via not shown gas exchange valves.
- the exhaust gas recirculation line 5 always remains connected to the intake passage 2 with its full passage cross-section. Is by closing the exhaust valve 7, the exhaust back pressure increases in the exhaust pipe 4, is correspondingly more Exhaust gas returned to the intake.
- thermocouple is preferably a bimetallic spring or a memory spring.
- Exhaust flap 7 may be known for engine braking devices exhaust flap be used.
- the internal combustion engine 1 is preferably a self-igniting internal combustion engine (Diesel engine), especially for use as stationary Motor, preferably for driving a generator for generating electricity.
- Diesel engine a self-igniting internal combustion engine
- the internal combustion engine is air-cooled and has an injection system on, which has a mechanical regulator for controlling the Injection has.
- Figure 3 shows an exhaust gas recirculation line 5 made of gray cast iron with a Inner 9 and outer ribbing 10 in plan view and longitudinal and cross section.
- the outer ribbing 10 is in this embodiment of itself in the radial direction of the exhaust gas recirculation line 5 extending and on the outer circumference circumferential rib rings 11.
- the individual Rib rings 11 are arranged one behind the other with the same distance.
- the inner ribbing 9 consists of one behind the other in the longitudinal direction arranged rib rings 12. These rib rings 12 are each from individual in the longitudinal direction and radially inward extending ribs 14. The size of these ribs 14, i. their Length in the longitudinal direction is the same for all ribs.
- the ribs 14a of a rib ring 12a offset to the ribs 14b of its adjacent rib ring 12b arranged. This offset is half the distance between two adjacent ribs 14 of a rib ring 12th
- Each rib ring 12 preferably consists of ten to twenty-two at the same distance on the inner circumference arranged ribs 14th In this preferred embodiment in FIG. 3, each one exists Rib ring 12 of sixteen at the same distance on the inner circumference arranged ribs 14th
- the reference numeral 13 denotes a connecting flange, which - as shown - as a screw or even for example can be designed as a plug-in flange.
