Definitions
- the invention relates to a method for starting an internal combustion engine, preferably an internal combustion engine with direct injection.
- the invention further relates to an internal combustion engine designed to carry out such a method.
- DE 198 35 045 C2 discloses a method for starting an internal combustion engine by igniting an air-fuel mixture in a cylinder ("Working cylinder"), the pistons of which stop when the internal combustion engine is at a standstill a working cycle position.
- the should be inside the working cylinder contained air volume can be estimated based on various sensor data. It however, it is not specified in detail how this should be done. It is also with disadvantageous in such a procedure that, for example, due to residual exhaust gases Knowing the amount of air in the cylinder alone is not sufficient for a subsequent one Being able to control combustion optimally.
- the method according to the invention is used to start an internal combustion engine, which in particular can be an internal combustion engine with direct injection of the fuel into the combustion chamber (cylinder) and with spark ignition.
- the combustion of an air / fuel mixture is carried out in the first working cycle of the piston of at least one cylinder of the internal combustion engine, which is referred to below as the "working cylinder", which occurs during the starting phase of the internal combustion engine.
- the method according to the invention is characterized in that the oxygen concentration in the working cylinder is determined before the starting phase of the internal combustion engine, and in that a quantity of fuel to be burned is metered in as a function of the determined value.
- the oxygen concentration is preferably expressed as a relative quantity which describes the proportion of pure oxygen O 2 in the gas mixture in the working cylinder, this proportion in mass percentages, volume percentages. Mole percentages can be expressed as partial pressure or as another suitable size. Such a relative value is independent of the volume of the combustion chamber.
- the necessary and sufficient for good combustion Amount of fuel determined very precisely and then z. B. by direct injection be fed to the working cylinder.
- the mechanical energy from the combustion can for example to be used to the internal combustion engine without another auxiliary unit (Starter engine etc.) solely by igniting the air-fuel mixture to start in the working cylinder, whereby the piston of the working cylinder is at The internal combustion engine is at a standstill in one work cycle (expansion cycle) got to.
- the combustion can only be supportive during the start phase act for starting the internal combustion engine with an auxiliary unit. This made it possible e.g. B., a less powerful and therefore cheaper Auxiliary unit to use.
- the acid concentration can also be measured in the compression cylinder with this method are determined, with the help of which the actual starting process upstream reverse rotation according to DE0010020325A1, to improve starting can be initiated.
- the determined oxygen concentration is preferably used to from this the absolute amount of oxygen (e.g. as mass value or as number of moles) in Determine working cylinder at the start of the start phase. From the amount of oxygen can then directly supply the amount of fuel for a stoichiometric Combustion can be calculated.
- the absolute amount of oxygen from the oxygen concentration can advantageously start anyway variables measured in an internal combustion engine, such as the crankshaft angle, atmospheric pressure and / or engine temperature (or coolant temperature) be used.
- the assessment is carried out in order to minimize the effort for data processing the oxygen concentration preferably based on an average and / or due to an accumulated, that is, summed up or integrated value of the sizes mentioned (internal cylinder pressure, intake pressure and / or air mass flow).
- the measurement of the suction pressure can preferably be carried out at the lower one Dead center of the piston of the working cylinder take place.
- the invention further relates to an internal combustion engine, preferably one Internal combustion engine with direct injection and spark ignition, which thereby is characterized in that they carry out a method of the above Art is set up.
- the internal combustion engine can be controlled by an engine be equipped, which is programmed so that it the oxygen concentration in the working cylinder of the internal combustion engine for the calculation of the to be metered Amount of fuel for the first combustion in the working cylinder during used in the start-up phase.
- the internal combustion engine can continue with the Engine control coupled sensors for the air mass flow in the intake manifold, for the intake pressure and / or for the cylinder internal pressure to get out of these Sizes to determine the oxygen concentration.
- the internal combustion engine 10 shown in FIG. 1 is a Internal combustion engine with direct injection of petrol into the cylinder 3 leading fuel supply 6.
- a direct injection engine has the Advantage that he by ignition of the air-fuel mixture in the cylinders 3rd can be started directly without an additional starter motor the crankshaft must drive during a starting phase.
- the (foreign or Self-) ignition of an air-fuel mixture during the starting phase however also only to support a starter (starter motor) to make the starting process to accelerate (“Quick Start”), to be able to design the starter smaller, and to improve the comfort behavior of the conventional start.
- a supported start is already from the first revolution or Fuel injected from the first expansion stroke of a piston and ignited.
- the internal combustion engine 10 also has an intake manifold 2 for supplying fresh air, the supply rate of which can be adjusted via a throttle valve 1.
- An air mass flow sensor 8 is arranged upstream of the throttle valve and transmits a signal representing the air mass flow MAF to an engine control unit 7, which can be implemented, for example, by a microprocessor.
- a pressure sensor 9 for the intake pressure p man is arranged downstream of the throttle valve 1, the signal of which is also passed to the engine control 7.
- pressure sensors 4 for the internal cylinder pressure p cyl are provided in the cylinders 3 of the internal combustion engine, which transmit their signals to the engine control 7.
- the exhaust gases from the cylinders 3 of the internal combustion engine 10 are from a Exhaust manifold 5 passed into an exhaust system, not shown.
- an exhaust gas recirculation system an exhaust gas turbocharger, a catalytic converter and the like, which are not shown in FIG. 1 are.
- the engine control 7 receives the above and a number of other sensory ones Information (e.g. engine speed, coolant temperature, the ambient pressure etc.) and calculates control commands for different ones Components of the internal combustion engine.
- Figure 1 is only the output of the engine control unit 7 to the fuel injection system 6 is shown, Via which the engine control unit 7 controls the fuel injection (time, duration, fuel quantity, Fuel pressure) can control.
- the absolute amount of oxygen in the working cylinder 3 depends on the volume of the combustion chamber formed by the cylinder walls and the piston (and thus the position of the crankshaft), on the air density, and on the oxygen concentration c 0 of the cylinder charge.
- the absolute crankshaft position can easily be determined by an angle sensor or a similar device.
- the air density can be determined by the pressure and the temperature in the working cylinder, the pressure being approximately equal to the ambient pressure (atmospheric pressure) and therefore easily predictable, while the temperature can be approximated by the coolant temperature, which is usually monitored by an appropriate temperature sensor.
- the continuously recorded measurement data of the cylinder internal pressure p cyl , the intake pressure p man and / or the air mass flow MAF can be used during the stopping phase of the engine. Alternatively, only a few data can be used at predefined positions of the camshaft or crankshaft. Due to the typically limited resources of computing capacity in the engine controller 7 (FIG. 1), a prediction of the oxygen concentration c 0 by selecting only a few data of the internal cylinder pressure, the intake pressure and / or the air mass flow at predefined crankshaft angles is advantageous, since this can minimize the computing effort.
- FIG. 2 shows the course over time of the intake pressure p man , the engine speed n and the internal cylinder pressure p cyl for a working cylinder (solid line) and the remaining three cylinders (dotted lines) of the internal combustion engine 10 during a phase-out phase that occurred at time 0 ( "off") begins with the switching off of the fuel supply and / or the ignition.
- the points in time TDC1, TDC2 and TDC3 in the figure are indicated by dashed lines, at which the piston of the working cylinder of the internal combustion engine passes top dead center for the first, second and third (and last) times in the phase-out phase.
- the preceding passage of the piston through the bottom dead center is marked with BDC1, BDC2 and BDC3.
- p cyl1 , p cyl2 and p cyl3 the measured values of the internal cylinder pressure p cyl in the working cylinder at the first times TDC1, TDC2 and TDC3.
- FIG. 3 shows schematically the relationship between the oxygen concentration c o and the mean cylinder pressure ⁇ p cyl >.
- Such a relationship can be determined empirically and, for example, recorded in a lookup table or a mathematical approximation function in order to be available to the engine control system.
- FIG. 2 it is also indicated that the intake pressure p man can be recorded each time the bottom dead center BDC1, BDC2, BDC3 is passed during the phase-out of the internal combustion engine.
- This mean value can then be converted into an oxygen concentration c o on the basis of the relationship shown schematically in FIG.
- the internal cylinder pressure p cyl and the intake pressure p man can also be used in combination to estimate the oxygen concentration c o in the working cylinder.
- the measured or calculated data of the air mass flow MAF (on average or cumulatively) could also be used.
