The delivery pipe 25 is connected to the G fuel injector 10B.
Liquefied gas fuel pipe (LPG fuel pipe) 20
And return pipe for liquefied gas fuel (return pipe for LPG fuel)
The LPG fuel pipe 20 is provided with a liquefied gas fuel cutoff valve (LPG fuel cutoff valve) 21. The LPG fuel pipe 20 is connected to a discharge port of a liquefied gas fuel pump (LPG fuel pump) 27 provided inside or outside a liquefied gas fuel tank (LPG fuel tank) 26, and the LPG fuel return pipe 28 is connected to the LPG fuel. It is connected to a tank 26. An electronic control circuit (ECU) 50 includes an intake pressure sensor 51 provided in the surge tank 11, an O 2 sensor 52 provided in the exhaust manifold 9, and an exhaust pipe 15.
Exhaust temperature sensor 53 and throttle valve 12
A fuel injection amount, an ignition timing, and the like are obtained based on an operation state detection signal from a throttle sensor 54 that detects the opening of the engine, a cooling water temperature sensor 55 provided in the cylinder 2, and the like, and the injectors 10A and 10B, the ignition plug 7, and the like. Control the operation of. Further, the electronic control circuit 50 performs fuel switching control as described later by operating the fuel switch 60 by the driver. Next, fuel switching control by the electronic control circuit 50 will be described with reference to FIG. FIG. 2 shows the contents of control at the time of switching fuel from gasoline fuel to LPG fuel. In FIG. 2, the electronic control circuit 50 drives the gasoline fuel pump (gasoline pump) 24 (step S1) and keeps the gasoline fuel shutoff valve (gasoline shutoff valve) 19 open (step S2). Then, the gasoline fuel injector (gasoline INJ) 10A is driven to inject gasoline fuel into the cylinder 2 at an injection timing and injection amount suitable for the operating state of the engine (step S).
3). Thereafter, when the driver operates the fuel switch 60 to instruct fuel switching from gasoline fuel to LPG fuel (step S4), the LPG fuel pump (LPG pump) 27 is driven (step S5). At the same time, the LPG fuel cutoff valve (LPG cutoff valve) 21 is opened (step S6). Then, driving of the LPG fuel injector (LPGINJ) 10B is started, the injection rate is increased at a constant rate, the injection amount of the LPG fuel (liquid) is increased by, for example, 10% (step S7), and the gasoline fuel is increased. Injector (gasoline INJ) 1
The drive of 0A is continued, the injection rate is reduced at a fixed rate, and the injection amount of gasoline fuel is reduced by, for example, 10% (step S8). With such injection control, LP
When the injection amount of the G fuel (liquid) becomes 100% and the injection amount of the gasoline fuel becomes 0% (step S9), the driving of the gasoline fuel injector (gasoline INJ) 10A is stopped (step S10) and the gasoline fuel is injected. The shutoff valve (gasoline shutoff valve) 19 is closed (step S11),
Further, the driving of the gasoline fuel pump (gasoline pump) 24 is stopped (step S12). FIG. 3 shows a timing chart at the time of fuel switching as described above. As shown in FIG. 3, when the driver operates the fuel changeover switch 60 to instruct switching from gasoline fuel to LPG fuel, the gasoline fuel cutoff valve (gasoline cutoff valve) 19 is turned on or opened. LP while being held
The G fuel cutoff valve (LPG cutoff valve) 21 changes from off to on, that is, from closed to open, and the gasoline injection rate becomes 10%.
And the LPG fuel is reduced by 10%
The LPG fuel (liquid) is increased by 1
When it reaches 00%, the gasoline fuel shutoff valve (gasoline shutoff valve) 19 changes from on to off, that is, from open to closed. Although not shown, the electronic control circuit 50 also performs fuel switching control when the driver operates the fuel switch 60 to instruct fuel switching from LPG fuel to gasoline fuel. Conversely, the injection amount of the LPG fuel (liquid) is decreased stepwise by 10%, and the injection amount of the gasoline fuel is increased stepwise by 10%. As described above, the fuel supply control device for an engine according to the present embodiment includes a liquid fuel injector (gasoline fuel injector) 10A for injecting liquid fuel (gasoline fuel) into the cylinder 2, a liquefied gas injector And a liquefied gas fuel injector (LPG fuel injector) 10B for injecting fuel (LPG fuel) into the cylinder 2; a liquid fuel injector (gasoline fuel injector) 10A; and a liquefied gas fuel injector (LPG fuel injector). A) a fuel supply control device for an engine that selectively drives 10B to selectively supply liquid fuel (gasoline fuel) and liquefied gas fuel (LPG fuel) into the cylinder 2; Liquefied gas fuel (L
At the time of the fuel switching of the PG fuel), the injection amount of the fuel that has been supplied until then is reduced at the same rate with the passage of time, and at the same time, the injection amount of the fuel to be supplied is the same with the passage of time. It is configured so that the amount increases. For this reason, according to the present embodiment, when the fuel is switched, the fuel injected into the cylinder 2 gradually changes from the fuel before switching to the fuel after switching, so that appropriate control to the A / F is performed. And the engine body is less likely to shock. The liquefied gas fuel is LPG as described above.
In addition to fuel, CNG fuel or the like may be used. The liquid fuel is not limited to gasoline fuel. According to the present invention, when the fuel is switched between the liquid fuel and the liquefied gas fuel, the injection amount of the fuel that has been supplied until then is reduced at the same rate with the passage of time. Since the injection amount of the fuel to be supplied from now on is increased at the same rate with the passage of time, it is possible to control the A / F appropriately, and it is difficult for the engine body to generate a shock.
