Definitions

  • the invention relates to an internal combustion engine with a crankshaft and a flywheel, which is arranged on the crankshaft.
  • the invention relates to a method for the controlled shutdown of such an internal combustion engine.
  • the crankshaft of an internal combustion engine receives the connecting rod forces, which are composed of the gas forces due to the fuel combustion in the combustion chamber and the mass forces due to the non-uniform movement of the engine parts.
  • the oscillating lifting movement, in particular of the pistons is transformed into a rotating rotational movement of the crankshaft.
  • the crankshaft transmits the torque to the drive and to the flywheel.
  • the crankshaft has a certain torsional elasticity and together with the hinged to them components, in particular the connecting rods and pistons, a vibratory system which can be excited by the acting on the crank pin gas and inertial forces to torsional vibrations.
  • torsional vibration dampers can be provided. By a relative movement of the mass of the vibration damper to the crankshaft, a part of the torsional vibration energy is reduced by friction work.
  • the mass of the described oscillatory system is increased by the arrangement of a flywheel on the crankshaft. Due to the larger mass, the system has increased inertia, which makes the system more insensitive to speed variations and makes the rotational motion of the crankshaft more uniform.
  • the flywheel stores energy and transmits it to the crankshaft as the speed drops. Ie. the flywheel serving as an energy reservoir releases energy to the crankshaft as it decelerates, giving the crankshaft and the entire system a degree of inertia by attempting to counteract the deceleration and sustain movement by releasing energy. In this way, the flywheel acts both for accelerations and delays for a smooth and smooth running of the crankshaft and coupled to the crankshaft components.
  • the flywheel or the high mass therefore also affects misfires and misfires. Due to the inertia of the flywheel, the rotational motion of the crankshaft remains more or less uniform, i. the rotational movement is only slightly disturbed.
  • the flywheel can also be designed as a two-mass flywheel and then assumes the additional function of a vibration damper, which reduces the torsional vibrations between the clutch and the drive.
  • the flywheel is attached on one side to the crankshaft and connected on the other side via the clutch to the transmission.
  • the two disc-shaped parts are connected to each other by means of internal coil springs.
  • crankshaft and the flywheel are manufactured as separate independent components and then screwed together during assembly ie inextricably linked.
  • both components have flanges and arranged in the flanges slugs or holes.
  • a method for the controlled shutdown of an internal combustion engine generally follow the reduction of the fuel consumption of the internal combustion engine. Due to the limited resources of fossil fuels, in particular due to the limited mineral oil reserves as a raw material for the production of fuels for the operation of internal combustion engines, the development of internal combustion engines is constantly striving to minimize fuel consumption. On the one hand, the improved i.e. more effective combustion in the forefront of the effort. On the other hand, certain strategies with regard to the basic operation of the internal combustion engine can also be effective.
  • One concept for improving the fuel consumption of a vehicle is, for example, to switch off the internal combustion engine - instead of continuing to run it in the leelauf - when there is no momentary power requirement. In practice, this means that at least when the vehicle is stationary, the internal combustion engine is turned off.
  • One application is the stop-and-go traffic, as it sets, for example, in traffic jams on highways and highways. In inner-city traffic, stop-and-go traffic is no longer the exception, but the rule, as a result of the existing and non-coordinated traffic lights. Other applications provide limited level crossings and the like.
  • an internal combustion engine which is equipped with an electronically controlled ignition and / or electronically controlled injection, deliver at the Crankshaft arranged markers Signals about the crank angle position on connected to the engine control sensors for controlling the ignition and the injection timing. But to generate these signals, it is first necessary to put the crankshaft in rotation. Immediately at the beginning of the restart and the start in general, there is uncertainty about the correct injection and ignition timing, so that a run-in phase for the synchronization of the crank angle position on the one hand and the engine operating parameters on the other hand is required.
  • devices for starting or restarting the internal combustion engine must be provided, for example, a conventional starter or a similar device which is adapted to forcibly set the crankshaft in rotation, such as an electric motor.
  • German patent application DE 42 30 616 proposes, for example, to store the angular position of the crankshaft, which is registered at shutdown, and to use for the restart, so that the appropriate ignition timing and injection times are immediately available.
  • this approach has not proven in practice, since the stored information about the position of the crankshaft are too inaccurate.
  • Controlled parking consists in deliberately approaching certain crank angle positions - so-called preferred positions - when the internal combustion engine is switched off.
  • the end position of the crankshaft is no longer left to chance and more or less accurately registered, but it will be specifically brought about for the restart advantageous crank angle positions.
  • crankshaft must be in a specific position or in a specific crank angle range. In this respect, especially for internal combustion engines with direct injection method for controlled parking targets.
  • WO 01/48373 teaches the use of a method in which after switching off d. H. after completion of the regular operation of the internal combustion engine, an adjusting device is activated and controlled, with which the crankshaft and / or the camshaft is moved into a predefinable advantageous angular position. Both active and passive adjustment devices can be used.
  • an active adjusting device can serve an electric motor which transmits a torque to the crankshaft and this rotates after switching off the internal combustion engine in the desired position, which is then maintained until the restart of the internal combustion engine.
  • active adjusting devices which have means for activating the injection and ignition of the internal combustion engine after completion of their regular operation. These means are used to selectively initiate combustion processes in the cylinders, with which a certain torque is transmitted to the crankshaft, so that a predetermined advantageous crank angle position can be approached.
  • Passive adjusting devices but can also be used according to WO 01/48373, said passive adjusting after the normal operation of the internal combustion engine exploit the still existing in the wake of the crankshaft rotary motion and influence in the way that the Crankshaft comes to a standstill in the predetermined advantageous crankshaft position.
  • a passive adjustment means include a gas exchange valve control, which transmits a suitable braking brake torque to the engine or crankshaft, so that the delay of the shaft and thus its end position is controllable.
  • the adjusting devices shown in WO 01/48373 are not suitable for controlling the end position of the crankshaft with the required accuracy.
  • the active adjustment either make additional components - such as possibly not yet existing electric motors - required for applying a Verstellmosmomentes, or they work as in the initiation of targeted combustion processes for starting the predetermined crank angle position by means of an additional fuel injection and ignition.
  • the latter method which requires the use of fuel, is in sharp contrast to the fundamental goal of switching off the internal combustion engine, namely to save fuel by switching off the engine and thus to optimize the fuel consumption of a vehicle.
  • the use of an electric motor is not effective in this aspect, since the energy needs of the electric motor adversely affects the overall efficiency of the engine, which is also in contradiction to the actual objective to optimize the efficiency through fuel economy.
  • the passive adjustment devices offer the advantage that their energy consumption is usually lower and also acceptable in terms of the underlying task value, since the passive adjustment devices do not initiate a rotational movement of the crankshaft, but in principle only one Delay existing rotational movement of the crankshaft in a suitable manner.
  • a method for the outlet control of an internal combustion engine in which specifically the gas exchange valves of the internal combustion engine for controlling the Preferred positions are used, is described in WO 01/44636 A2.
  • suitable control ie by suitably opening and closing the gas exchange valves, influence is thereby exerted on the combustion chamber pressure and thus on the torque exerted by the gas forces on the piston and the connecting rod on the crankshaft.
  • this method requires an internal combustion engine which has an at least partially variable valve control.
  • a complex and therefore complex control is required.

  • Another object of the present invention is to provide a method for the controlled shutdown of such an internal combustion engine.
  • the first sub-task is solved by an internal combustion engine with a crankshaft and a flywheel, which is arranged on the crankshaft, and which is characterized in that the flywheel for controlled stopping and starting of the internal combustion engine has a variable flywheel mass.
  • flywheel mass is basically referred to in the context of the present invention, the total mass of the flywheel.
  • flywheel mass the mass of at least one fixed d. H. permanently connected to the crankshaft flywheel component referred. Such embodiments will be described in more detail below.
  • the flywheel mass has a significant influence on the outflow of the crankshaft, i. on the rotational movement of the crankshaft after stopping the engine and thus to the end position of the crankshaft.
  • the rotational movement of the crankshaft is significantly determined by the inertial forces that result from the delay of the individual engine parts, such as the pistons and the connecting rods, and in particular by the delay of the flywheel.
  • the moment of inertia of the flywheel is varied and the inertial forces or the attacking moment of inertia acting on the flywheel as a result of the deceleration during the outflow process are influenced.
  • the mass of the flywheel can be selectively increased and decreased. If this happens in the appropriate manner, the internal combustion engine can be turned off in a controlled manner d. H.
  • the completed after switching off the ignition and / or the fuel supply from the crankshaft to its standstill rotational movement is delayed by means of the variation of the flywheel mass in such a way that the crankshaft is stopped in a predeterminable position.
  • the internal combustion engine according to the invention also allows a simple and fuel-efficient restart, since the crankshaft can be stopped selectively in a so-called preferred position, ie in a crank angle range for the start of the internal combustion engine is to be regarded as advantageous.
  • a gasoline engine with direct injection can be started directly from standstill by injection of fuel into the cylinder and ignition of the injected fuel.
  • the flywheel mass can be minimized for the start or restart of the internal combustion engine, whereby the required starting energy is reduced to a minimum. After the successful starting process, the flywheel mass is then on the normal d. H. regular operation of the internal combustion engine necessary size increased or adjusted.
  • the inventively proposed variation of the flywheel mass or the variable flywheel mass can basically be regarded as a passive adjustment in which by suitable variation of the flywheel mass due to the changed moment of inertia of the flywheel not constant torque is exerted on the crankshaft to the crankshaft - preferably in the desired Preferred position - comes to a standstill.
  • kinetic energy stored in a flywheel component decoupled from the crankshaft may, under certain circumstances, be used for a restart, which will be explained in more detail in the context of the preferred embodiments.
  • flywheel a basically already existing component of the internal combustion engine is used to accomplish a controlled shutdown.
  • the provision of additional adjustment is not required.
  • active adjusting device for example an electric motor, as proposed by WO 01/48373, must be provided in order to turn the crankshaft to the desired position after the internal combustion engine has been switched off.

  • Embodiments of the internal combustion engine in which the flywheel is a continuous d are advantageous.
  • H. has continuously variable flywheel mass.
  • a continuously variable flywheel mass ensures the highest degree of flexibility when parking the internal combustion engine and starting up the so-called preferred positions.
  • a continuously variable flywheel mass increases the accuracy with which the preferred positions can be approached.
  • a continuously variable flywheel mass for example, be realized in that a hollow flywheel body is provided, which can be filled with liquid, such as water. By introducing additional liquid into the hollow body, the flywheel mass is increased, whereas by discharging liquid contained in the hollow body, the mass of the flywheel is reduced.
  • Embodiments of the internal combustion engine in which the flywheel is modularly constructed from at least two flywheel segments are advantageous connectable to each other and are detachable, so that the flywheel mass is at least two stages changeable, wherein at least one flywheel segment is non-detachably connected as a base segment with the crankshaft.

  • the division of the flywheel mass into a plurality of individual masses which can be detached from one another is an example of such an embodiment, wherein the crankshaft is brought into a desired preferred position in a multi-stage process.
  • the rotating crankshaft is delayed in a first step by suitable replacement of individual flywheel segments of the base segment and the Brought to a standstill.
