Definitions

  • DE 33 17 128 A1 describes an internal combustion engine, which according to a Six-stroke cycle works.
  • a fuel-air mixture embedded in the cylinder which in a first compression stroke is compressed.
  • a first power stroke Following the ignition of the compressed fuel-air mixture there is a first power stroke.
  • the combustion products are compressed.
  • the cylinder content is ignited by a spark plug.
  • a second power stroke follows as a result of the expansion of the compressed Combustion products and finally an exhaust stroke, during which the Combustion gases are driven out of the cylinder.
  • a method for operating a gasoline-fueled internal combustion engine is known, the engine operating area of which has auto-ignition and spark-ignition areas.
  • the internal combustion engine is operated by self-ignition during the partial load, a homogeneous fuel-air mixture being generated in the combustion chamber and the combustion being initiated by self-ignition of this fuel mixture.
  • the designated from the English-speaking world as the HCCI process (H omogenous C harge C ompression I gnition) method has particular advantages with regard to the development of emissions.
  • AT 5.140 U describes a process with which the self-ignition of the homogeneous fuel-air mixture can be controlled by the residual gas content in the combustion chamber.
  • the exhaust gas temperature itself is sufficient, especially at low speeds and loads at extremely high amounts of residual gas, however, no longer enough, so the filling to warm up strongly so that a safe self-ignition is achieved. Moreover the longer cycle times at low speeds have a negative effect on the Filling temperatures because there is more time for heat transfer.
  • the object of the invention is to avoid these disadvantages and a method to develop an internal combustion engine, on the one hand high efficiency and low emissions can be achieved can.
  • this is achieved in that the injection of the second Subset of petrol in the third stroke, preferably in the second half of the third cycle, there is at least one in the combustion chamber before the second ignition approximately homogeneous fuel-air mixture is formed and that the second ignition by compression ignition of this homogeneous air / fuel mixture he follows.
  • the fuel-air mixture formed during the second stroke is lean and stratified and has a large excess of air with an air / fuel ratio of ⁇ > 1.5.
  • the excess air ensures that sufficient oxygen is still available for the second combustion.
  • the lean stratified combustion produces only very low NO x emissions.
  • the temperature of the burned gas is relatively low, but high enough to guarantee safe auto-ignition in the second combustion cycle. It is particularly advantageous if, by adjusting the size of the first subset of the gasoline fuel injected in the second stroke, the combustion that takes place in the fifth stroke following the second ignition is regulated. By simply varying the amount of the first injection or by changing the division between the first and second injection, the composition of the combustion gas and thus the starting condition for the compression ignition can be changed or adapted.
  • stratified combustion has the advantage of very high efficiency.
  • a pressure adjustment is carried out in the combustion chamber.
  • the pressure level regulation in the combustion chamber can be used to control auto-ignition. It is particularly advantageous if the pressure adjustment by a short-term Opening at least one lift valve, preferably an inlet valve becomes.
  • a first cycle consisting of the sixth and the first cycle serves to change the gas, that is to say to push out exhaust gas and to draw in fresh fill.
  • the second cycle - the second and third clock consists of compression, spark ignition, stratified lean combustion (SCSI - S tratified C harge S pat gnition I) and expansion and forms the first cycle of operation.
  • the lean exhaust gas from this first work cycle is not pushed out but remains in the cylinder and serves as a filling for the following third cycle (fourth and fifth stroke).
  • This third cycle is the second work cycle and is characterized by homogeneous compression ignition (HCCI). This is followed by the exhaust of the first cycle.
  • HCCI homogeneous compression ignition
  • the invention is illustrated by the figure.
  • the figure shows the valve strokes h of the exhaust valves and the intake valves, wherein with reference number 1 the exhaust valve lift and with reference number 2 the intake valve lift is designated.
  • Line 3 shows the injection events in the combustion chamber.
  • the working process has six bars I, II, III, IV, V, VI, two each Bars belong to a cycle A, B, C.
  • the first cycle A is used to change the gas and consists of the clock VI for pushing out the exhaust gas and the clock I for Sucking in air.
  • the second cycle B consists of the clock II, in which the Air is compressed in the cylinder and a first subset of petrol is injected, as well as stroke III, the first working stroke of the piston.
  • the first subset of petrol is injected, such as is indicated with reference number 3a.
  • an igniter such as is indicated by reference numeral 5. This leads to a lean stratified combustion.
  • the lean exhaust gas from the first work cycle B is not pushed out, but remains in the cylinder and serves as a filling for the next one third cycle C, the second cycle.
  • the second cycle has the stroke IV, during which the cylinder content is recompressed, and the Cycle V, the second working stroke of the piston.
  • a short opening can at least of an intake valve may be provided to regulate the pressure level in the cylinder.
  • This brief opening of the inlet valve is indicated by reference number 2a.
  • the pressure adjustment by briefly opening the inlet valve in the area bottom dead center between cycle III and cycle IV can be for the Control of the auto ignition can be used.
  • the stratified lean combustion in the cycle B works with high air surplus and produced especially for very little fuel injected very low NO x emissions.
  • the temperature of the burned gas is also relatively low, but high enough to guarantee reliable auto-ignition in the following working cycle C.
  • the composition of the combustion gas and thus the starting condition for the compression ignition 6 can be changed or adapted. Both stratified combustion and homogeneous self-ignition are characterized by high efficiency.
  • Compression ignition 6 offers significant advantages, particularly with regard to NO x and soot emissions.
  • the fact that any soot or hydrocarbon emissions from the first work cycle B are fed to a further combustion and thus burned also has a positive effect on the emissions.
