Definitions
- the invention relates to a starter of an internal combustion engine with the features mentioned in the preamble of claim 1.
- Starters of the generic type are known.
- the starter of such starters can be formed, for example, by an excitation gear which transmits the thrust movements of the pressure relay and the rotary movement of the electric starter motor in a suitable manner to the pinion.
- the electric motors used to start internal combustion engines are DC, AC or three-phase motors.
- the DC series motor is particularly suitable as a starter motor because it develops the high starting torque required to overcome the starting resistance and to accelerate the engine masses.
- the starter's torque is predominantly transmitted to the flywheel on the crankshaft of the internal combustion engine via a pinion and a ring gear.
- V-belts, gears, chains, gears or direct transmission to the crankshaft are also selected.
- the pinion starter can, due to the large translation between the starter pinion and the sprocket, Torschwungsche oe be designed such that the torque is high at low speeds.
- Exhaust emissions are independent of the type of starter used. is comparatively high during the starting process, since the " combustion process is not optimal below the idling speed of the internal combustion engine.
- the transmission has at least one first gear ratio and a second gear ratio that is lower than the first gear ratio, that the first gear ratio is used at least during a first starting phase of a starter process, and that, at least when a predetermined ambient temperature is exceeded, the second gear ratio is used during a second start phase lying behind the first start phase, it is possible to pull the internal combustion engine up to a speed which is close to the idle speed of the internal combustion engine before using a single starter Fuel is injected into the cylinder and ignited.
- the starter according to the invention enables a significant reduction in the exhaust gas emission value occurring during the starting process, with little effort compared to solutions with two starters.
- the ambient temperature is extremely low, for example less than -10 ° C, below the specified ambient temperature, it may be advantageous to operate the starter only with the first gear ratio, since overall significantly higher drive torques are then required.
- the solution according to the invention with switching of the translation during the starting process manages with a significantly reduced starting power, since the power is adapted by the change in translation in the course of the starting process.
- the first start phase preferably begins with the start of the start process. In this case, be the first. Drive through the compression stroke due to the high start-up speed with good acceleration and no torque. This means that the higher load torque at the start of the starting process, which is generated, among other things, by the gas spring moments and additional loss torques of the distortion motor, can be overcome, with the higher moments of inertia creating an additional smoothing effect.
- the change from the first gear ratio to the second gear ratio is preferably controlled or regulated.
- the change from the first gear ratio ⁇ u to the second gear ratio can be speed-dependent.
- the change from the first gear ratio to the second gear ratio takes place at the speed at which the torques on the crankshaft for the first gear ratio and the second gear ratio are at least approximately the same size.
- the change from the first gear ratio to the second gear ratio can also take place if the torque transmitted to the gear becomes negative, ie if a drive torque from the combustion motor is transferred to the starter. In this case it was self-regulation.
- the change from the first gear ratio to the second gear ratio can be done, for example, by a planetary gear.
- the input of the planetary gear can be on the sun gear and the output on the planet carrier.
- the ring gear of the planetary gear can be fixed in the first gear ratio and connected to the sun gear side in the second gear ratio via a clutch.
- a coupling between the ring gear and the planet carrier or between the planet carrier and the sun gear is also conceivable to represent the second gear ratio.
- the starter according to the invention can be in the form of a starter generator which remains connected to the crankshaft during operation of the internal combustion engine and feeds energy into the vehicle electrical system.
- the system automatically switches to the first gear ratio, provided that this is not already being used at the time the starting process is aborted.
- Figure 1 is a schematic block diagram of an embodiment of the present invention.
- Figure 2 The course of the torque transmitted to the crankshaft, the crankshaft speed and the power, in a case in which the first gear ratio is nine and the second gear ratio is three.
- the starter is shown with S and the associated transmission with GT.
- the output shaft of the starter electric motor can be non-positively connected to the transmission GT, which in turn can be non-positively connected to the internal combustion engine VM, for example by means of an indented transmission part of the transmission GT.
- the gearbox GT has a control input ST, to which a control signal can be applied which can trigger a change from the first gear stage 1 to the second gear stage 2 and vice versa, it also being conceivable, of course, that more than only two gear stages are provided.
- the starter S has only a single electrical machine, and the change from the first gear ratio ii to the second gear ratio ⁇ 2 can, as mentioned above, be time-controlled and / or speed-dependent or suitably controlled or regulated in some other way.
- the higher first gear ratio i ⁇ is preferably optimized with regard to the cold start limit temperature.
- the lower second gear ratio ⁇ 2 is preferably on the generator set at higher crankshaft speeds and optimized for start-up support at start-up or for pulling up to a speed that is in the range of the idle speed of the internal combustion engine VM.
- the optimization is preferably carried out for an ambient temperature range which is above 20 ° C.
- the change from the first gear ratio i x to the second gear ratio i 2 is speed-dependent at the speed at which the torque achieved with the first gear ratio ii is equal to the torque achieved at this crankshaft speed with the second gear ratio i 2 - ment, or is exceeded by this.
- the curves shown in FIG. 2 apply to the starting process of a V ⁇ internal combustion engine, i.e. for an internal combustion engine VM which has six cylinders, three of which are each in a row, the two rows being arranged in a V-shape with respect to one another. Furthermore, the curves shown in FIG. 2 apply to an ambient temperature of 20 ° C.
- the starting process becomes very uncertain in the area of the first compression, which takes about 18 seconds in the illustration, since at this point the speed is only about 60 revolutions per mute.
- the speed is only about 60 revolutions per mute.
- the internal combustion engine VM with a somewhat higher drag torque under these circumstances it would no longer be possible, or at least no longer, to start safely.
- gear ratios have been described above using an exemplary embodiment in which the transmission has two gear ratios, the invention is in no way restricted to this number of gear ratios. Depending on the design of the internal combustion engine VM, more than two gear ratios can also be used. The change between the gear ratios can be made dependent on other environmental conditions or moto parameters so that not all available gear ratios are used in every case.
- the starter S is a starter generator
- a separate gear ratio can be provided for the generator operation.
