Definitions
- the invention relates to an electronic engine control system of an internal combustion engine according to the preamble of claim 1.
- Ignition and fuel supply are electronically controlled in modern internal combustion engines.
- lambda probes are used as 0 2 probes in the exhaust gas flow of the internal combustion engine, with which the composition of the exhaust gases is examined and the air content in the intake manifold is corrected in the case of an electronically controlled gasoline injection and, if appropriate, in the case of carburetor engines.
- a predeterminable fuel quantity is adapted by means of a fuel quantity adaptation device as an additional fuel quantity for an acceleration enrichment or as a reduced fuel quantity for a decelerating deceleration to a fuel quantity specified by a map control.
- Such an additional fuel quantity or a reduced fuel quantity is calculated depending on the degree of engine load change and the temperature. After initialization of an acceleration enrichment or a decelerating deceleration, these are reduced within a certain time via a control unit.
- control data for this are derived from the operation of an internal combustion engine.
- a number of influencing variables such as fuel quality, coked intake valves and intake manifold wall film effects, cannot be directly recorded and taken into account during such a dismantling, so that less favorable operating conditions that can be optimized can occur.
- the object of the invention is therefore to develop a generic electronic motor control of an internal combustion engine so that the operation of the internal combustion engine is further optimized in the event of load changes.
- a fuel quantity adaptation device and a correction unit are named separately above.
- the electronic components and / or electronic functions required for this are integrated in a single electronic component of the engine control unit in a conventional manner.
- Lambda probes according to claim 4 are designed as two-point probes with a digital output for a “lean” lambda signal and a “fetf lambda signal. lean "lambda signal is present. Lambda probes with a continuous signal output can also be operated as two-point probes in the above manner, if necessary, by using threshold value circuits. There are various options for determining and specifying a correction quantity:
- the additional correction quantity is preferably determined when the “lean” lambda signal is present by multiplying the currently adapted amount of fuel (additional fuel quantity for acceleration enrichment or reduced fuel quantity for decelerating deceleration) by a factor greater than 1.
- This factor can be greater than 1 can be calculated and specified as a function of further parameters, preferably the temperature and the degree of load change.
- the additional correction quantity in the presence of the “lean” lambda signal can be determined during an adaptation time by adding the adapted fuel quantity with a predefinable correction amount in the manner of a level shift.
- the additional correction quantity when the "lean" lambda signal is present can be determined by switching over to a stored correction map.
- a basic map and / or a load change map may be replaced or modulated if necessary.
- the adaptable fuel quantity and / or the adaptation time and / or the additional correction quantity are taking into account influencing factors. large adaptable and predictable to the current conditions.
- the temperature and the specific load change process are essential as influencing variables. If necessary, however, other detectable influencing variables can also be taken into account, which may be taken into account in the engine control anyway.
- the adapted amount of fuel is determined as acceleration enrichment or deceleration reduction by a relatively large short-term component which is bell-shaped within a relatively short time and a superimposed, relatively smaller long-term component which can be regulated relatively slowly until the end of the adaptation time.
- the long-term component is influenced here with the additional correction amount according to the invention, since within the short time of a suitable short-term component there is as a rule no reaction to a load change that can be detected via a “lean” lambda signal.
- the adapted fuel quantity is plotted over time in a diagram a>, with the plus sign denoting an additional fuel amount and the minus sign denoting a reduced fuel amount.
- a diagram b ) associated with diagram a ⁇ is shown, in which the lambda signal of a lambda probe, which is preferably designed as a 0 2 probe, is plotted over time.
- diagram a B shows the adaptation time for an acceleration with an acceleration enrichment.
- the adapted fuel quantity 1 is shown in diagram a> with a solid line and is determined by a relatively large short-term component 2 bell-shaped within a relatively short time and a superimposed, relatively smaller long-term component 3 that can be regulated relatively slowly until the end of the adaptation time B.
- a “lean” lambda signal is present on the lambda probe according to diagram b ⁇ of FIG. 1
- the adapted fuel quantity 1 is additionally adapted by a predefinable correction quantity 4.
- the adaptation takes place by means of the additional correction quantity 4 only until there is no longer a “lean” lambda signal at the lambda probe.
- the curve shape of the adapted fuel quantity 1 without such a correction is shown in dashed lines in diagram a ⁇ of FIG. 1.
- the additional correction quantity 4 can be determined by a factor greater than 1 by multiplying the fuel quantity 1 currently being adapted, ie the additional fuel quantity in the case of the acceleration enrichment being considered here.
- This factor greater than 1 can be determined again as a function of further parameters, such as the temperature and / or the degree of load change, are calculated and specified.
- an adapted fuel quantity 6 corresponding to a reduced quantity of fuel in the case of the decelerated deceleration present here is additionally adapted by a predeterminable correction quantity 5 in the presence of a “lean” lambda signal.
- the additional quantity is corrected Adaptation stopped by means of the correction excess quantity 5 as soon as there is no longer a “lean” lambda signal on the lambda probe.
- the correction surplus 5 can also be here, for example, when the "lean" lambda signal is present, by multiplying the fuel reduction be determined with a factor greater than 1, this factor greater than 1 in turn as a function of further parameters, such as B. the temperature and / or the degree of load change, can be calculated and specified.
- the lambda probe here is preferably designed as a two-point probe with a digital output for a “lean” lambda signal and a “fetf lambda signal.
- This lambda probe is equipped with the electronic components of a fuel quantity adaptation device and / or a correction unit that is integrated in a Electronic engine control unit are integrated, coupled, the lambda sensor can sense a lean mixture in the exhaust gas flow of the internal combustion engine.
- the long-term component 3 of the adapted fuel quantity 1 is influenced here, since within the short time of a suitable short-term component 2 there is generally not yet a reaction to a load change that can be detected by a “lean” lambda signal.
