Definitions
- the invention relates to a dual-fuel internal combustion engine having the features of the preamble of claim 1 and a method for operating a dual-fuel internal combustion engine with the features of the preamble of claim 7.
- Dual-fuel internal combustion engines are typically operated in two modes of operation. A distinction is made between a mode of operation with primarily liquid fuel supply (“liquid operation” for short, “diesel operation” in the case of using diesel as a liquid fuel) and a mode of operation with primary gaseous fuel supply in which the liquid fuel serves as a pilot fuel for initiating combustion (also referred to as “pilot operation”, “dual-fuel operation” or “ignition jet operation”).
- the control device In the pilot operating mode, in which the liquid fuel is introduced as pilot fuel, the control device is designed to control the fuel injector and the at least one gas supply means for selectively metering the amount of liquid or gaseous fuel supplied to the at least one piston-cylinder unit.
- the power is adjusted by adjusting the fuel quantity (fuel-guided system).
- Object of the present invention is therefore to provide a dual-fuel internal combustion engine or a method for operating a dual-fuel internal combustion engine with improved transient response.
- the control device In the pilot operating mode, the control device has an operating mode in which, in an expansion phase of the piston-cylinder unit, the fuel! Njektor the piston-cylinder unit liquid fuel is supplied, a better transient behavior of the internal combustion engine is achieved.
- the internal combustion engine can continue to operate in the operating mode with predominantly gaseous fuel, that is, it does not have to be switched to diesel mode, as is the case in the prior art for realizing fast transients.
- the invention is particularly relevant for use with stationary internal combustion engines and for marine applications.
- the internal combustion engines can serve as mechanical drives, for example for the operation of compressor systems, or be coupled to a generator to form sets.
- the control device is preferably designed such that it remains in the steady-state operating mode in the pilot operating mode until the load request is changed in terms of amount over a predetermined threshold value (eg more than 10% of the previous or current load request). If the threshold value is exceeded, the control device changes to the transient mode until the power provided by the internal combustion engine falls below a predetermined distance (eg less than 10% of the new load request) with respect to the new load request. Once this is the case, the controller changes back to steady state operation mode.
- a predetermined threshold value eg more than 10% of the previous or current load request.
- FIGS. 1 shows a diagram of an internal combustion engine of the invention
- 2a, 2b are diagrams of an injection rate and a heat release rate over the crank angle in the stationary operating mode (FIG. 2a) and in the transient mode (FIG. 2b).
- FIG. 1 schematically shows an internal combustion engine 1 with a piston-cylinder unit 2 and a fuel injector 3 Injection of liquid fuel.
- a piston-cylinder unit 2 is shown.
- generic internal combustion engines have a multiplicity of piston-cylinder units 2.
- a control device 5 can regulate the quantity of liquid fuel supplied to the piston-cylinder unit 2 (via the fuel injector 3) or the supplied quantity of gaseous fuel (via a gas supply device 4). Signal lines are indicated by dashed lines. For clarity, not all leading to the control device 5 signal lines are entered.
- Exhaust gases of the piston-cylinder unit 2 flow to an exhaust gas turbine 8 of a turbocharger 7.
- a compressor 9 Connected to the exhaust gas turbine 8 is a compressor 9.
- a gas supply device 4 is arranged downstream of the compressor 9.
- the gas supply device 4 may be designed, for example, as a port injection valve for the cylinder-specific metering of gaseous fuel.
- the gas supply device 4 is arranged upstream of the compressor 9.
- the gas supply device 4 may for example be designed as a gas mixer.
- the internal combustion engine 1 or the control device 5 is configured so that in the expansion stroke (the expansion phase) of the piston-cylinder unit 2 by the fuel injector 3 additional liquid fuel can be injected.
- the safe distance (how early after the top dead center may be injected) to the knock limit is determined by experiments.
- the safe distance depending on the load can z. B. are deposited as a look-up table in the control device.
- the distance to the knock limit also depends on the quality of the gas used as the gaseous fuel. Especially in marine applications, the gas quality can change due to segregation in entrained gas.
- a routine may be provided to determine the distance to the knock limit.
- the invention is particularly suitable for lean operation with a combustion air ratio lambda of, for example, 1.7 to 1.8. Even after combustion of a lean mixture with high excess air, a sufficiently high content of oxygen for oxidation of the liquid fuel is present. This residual oxygen content is also the limiting factor for the amount of additionally injected liquid fuel.
- the residual oxygen content in the at least one piston-cylinder unit 2 can be increased in the short term by actuating a wastegate 10 which can be actuated by the control device 5, whereby the amount of liquid fuel that can be converted in the transient mode can be increased.
- a wastegate 10 for this purpose could also be actuated by the control device 5
- Ver Whyrumblasung (engl, compressor bypass) 1 1 may be provided. Under actuation here is a change in the position of wastegate 10 and compressor 1 1 understood in the direction of lesser opening. A reduced opening position increases the lambda in the short term.
- FIG. 2 a shows an injection rate and a heat release rate plotted against the crank angle for the stationary operating mode.
- the top dead center at 0 ° crank angle is marked by a dashed vertical auxiliary line.
- the peak detectable in the course of the injection rate marks the pilot injection.
- FIG. 2b shows the injection rate and the resulting heat release rate over the crank angle according to the invention in the transient mode. Visible in the course of the injection rate in addition to the peak of the pilot injection and the injection in the expansion phase. It can be seen that as a result of this additional injection of liquid fuel in the expansion phase compared with the pilot injection, the course of the heat release rate drops less than in the case described in FIG. 2a.
- the area under the curve of the heat release rate can be interpreted as converted heat. It is clear that significantly more energy is converted by the inventive measure of the additional injection in the expansion phase of the internal combustion engine 1 in dual-fuel operation with gas as the main fuel, which contributes to a faster response of the turbocharger 7 as stated above.
