Definitions
- the invention relates to a method for operating an internal combustion engine with at least a four-stroke cylinder with controlled auto-ignition and Spark ignition, the four-stroke cylinder at least in a controlled Auto-ignition mode is operable.
- the internal combustion engine is, for example, a gasoline engine with one or more Four-stroke cylinders.
- Gasoline engines are mainly using a stoichiometric Mixture operated, which allows aftertreatment of exhaust gases.
- the stoichiometric operation may be by a lean operation, either by a homogeneous or stratified mixture can be reduced by direct injection.
- nitrogen oxide (NOx) emissions can be controlled by conventional three-way catalytic converters (TWC) are not treated. Because of this were Lean nitric oxide (LNT) storage systems that treat the lean exhaust gas can.
- LNT Lean nitric oxide
- Controlled auto-ignition in four-stroke gasoline engines is a new development which is constantly evolving with a rapidly changing state of the art.
- WO 01/46571 and WO 01/46573 each relate to a method of operation a four-stroke internal combustion engine in which the combustion with a Autoignition is achieved.
- the internal combustion engine has a Spark plug for spark ignition to, in particular at the first ignition of Internal combustion engine to supplement the Seibstzündungsvon.
- the auto-ignition only in partial load ranges / low speed ranges used while the spark ignition at full load / high Speed ranges is used.
- US 6,082,342 discloses a method of controlling auto-ignition in four-stroke engines disclosed. The conventional spark is during the Auto-ignition operation maintained.
- Valve gear provides an early exhaust valve closing (EEVC) and a late one Inlet valve opening (LIVO) available to residual gas with minimal heat loss to hold back in the combustion chamber.
- EEVC early exhaust valve closing
- LIVO Inlet valve opening
- the invention is based on the object, an improved method of operation an internal combustion engine, in particular a gasoline engine available which continues to operate after a misfire occurring during CAI operation can be.
- this is achieved in that the four-stroke cylinder after a CAI operating misfire following misfire Cycle is re-ignited in a spark ignition mode.
- FIG 2 the inventive method for operating a Internal combustion engine with at least a four-stroke cylinder with controlled Autoignition (CAI) and spark ignition are shown, with the four-stroke cylinder is operable at least in a controlled auto-ignition mode.
- Figure 2 represents Cycles n-4 to n-1 represent a normal CAI mode with normal ignition and show normal moment.
- the normal ignition is each with a dicklin faced Square 1, in which a ratio of fresh fuel / air mixture 2 and residual gas 3 is located.
- the fresh fuel / air mixture 2 is included obliquely hatched, wherein the residual gas 3 is marked as a bar.
- the CAl mode requires compliance with certain limits, such as one relatively high residual gas content and a certain temperature of the mixture. Provided the certain limits are exceeded, it comes to a misfire.
- the Misfire is indicated in Figure 2 with n (arrow 4). The time is by means of the arrow 5 shown.
- n + 1 In a cycle n + 1 is clearly shown that the residual gas content 3 based on the fresh fuel / air mixture proportion 2 is less.
- cycle n + 1 the Four-stroke cylinder re-ignited by spark ignition.
- the cycle n + 2 returns the four-stroke engine returns to CAI mode.
- the four-stroke cylinder runs in this mode, as clearly shown by the cycles n + 3 and n + 4.
- Cycles n-1 through n-4 each precede misfire Cycle, where n + 1 to n + 4 each have a cycle following the misfire represent.
- the four-stroke cylinder is operated at moderate load and engine speeds, wherein a significant proportion of residual gas 3 from the previous cycle is deposited or recycled, thereby initiating the CAI.
- the four-stroke cylinder After re-ignition of the four-stroke cylinder, it returns to CAI mode back. Thus, the four-stroke cylinder is only briefly in a cycle in the Spark ignition mode operated. Appropriately, the four-stroke cylinder returns back to CAI mode in the cycle following the re-ignition cycle, and will continue to operate in this.
- the re-ignition cycle is in FIG. 2 exemplified as n + 1, with the subsequent cycle exemplified as n + 2 is designated.
- the misfire is advantageous to only one cycle limited because all cycles following the re-ignition cycle (n + 2, n + 3 ...) to ignite in CAI mode.
- the four-stroke cylinder after a misfire in CAI mode does not fail, but by means of Spark ignition is re-ignited and then returns to CAI mode. This is done with a suitable control of the ignition and the injected Fuel quantity reached.
- the execution of the engine with Direct injection is a layered injection of fuel, which is a Ignition even at high air excess allowed and so the constant maintenance of the engine torque without changing the engine throttling allows.
