いる。(Prior Art) Some internal combustion engines for automobiles use a combination of gasoline and LPG as fuel. As a fuel supply means for such an engine, a conventional carburetor is installed for gasoline, and an LPG adapter for feeding LPG is interposed in the air duct that connects the air cleaner and the carburetor. An example is shown in FIG. carburetor 1
A crown-shaped cab horn 11 equipped with an air intake tube 11a is attached to the 0, and a bench lily tube 12a is built in.
An LPG adapter 12 equipped with an LPG intake pipe 12b and the air intake tube 11a are connected to a rubber air duct 13.
are connected with each other and tightened with clamps 14a and 14b. A rubber air duct 15 is attached to the upstream side of the LPG adapter 12 and tightened with a clamp 16a. The other end of the air duct 15 is connected to the clean side of an air cleaner (not shown). Also, as shown in Figure 3, the air cleaner is connected to carburetor 1.

要となる。(Problem to be solved by the invention) In the case of the LPG adapter installed inside the air cleaner as shown in Fig. 3, the direction of the bench lily pipe is in the direction of the height of the air cleaner, so the air cleaner becomes taller than the one for passenger cars. It is not suitable to be housed in the engine room. Therefore, as shown in Figure 2, there is a system that connects the LPG adapter with a separate duct, but since an air duct is required before and after the LPG adapter, and a certain distance must be provided between the air cleaner and the carburetor, it is necessary to consolidate the equipment arrangement and make it more compact. It is inconvenient for Also, since there are many connected parts, there are more chances for leakage to occur. Furthermore, the number of parts increases, and more labor is required for processing such as assembly and sealing.

The LPG fuel supply system is attached to the air intake port of the carburetor, and the other end of the air duct is connected to the clean side of the air cleaner. Air from the air cleaner flows into the carburetor from the air duct via the carburetor horn. The gasoline supply in the carburetor is the same as before. on the other hand
The LPG fuel coming from the LPG supply source to the annular chamber flows along with the engine's air intake, exits from the communication hole to the vent lily pipe section, and flows toward the carburetor.

The LPG adapter is placed over the joint on the cab horn side of the air duct that connects the air cleaner and the cab horn, and the air duct made of an elastic material is placed in the middle layer between the LPG adapter and the air intake tube of the cab horn so that it can be tightened. The number of connection points (where clamps are required) for intervening has been reduced from three to one, and since they are stacked with elastic material interposed, tightening is complete and there is no leakage, and the structure is consolidated and compact, making the parts more compact. There are fewer parts and assembly is easier.
