った。Conventionally, fuel switching devices in internal combustion engines that use different types of fuels, such as gasoline and LPG, or alcohol and gasohol in place of gasoline, and methane and hydrogen in place of LPG, are operated manually by the driver using a switch installed near the driver's seat. By selectively operating the switch, the on-off valves provided in the gasoline and LPG fuel passages are controlled. According to this method, gasoline with better drivability should be used when driving in cold weather or when driving on a hill, and should be switched to low-cost LPG during other normal driving, but if the driver forgets to switch, fuel costs will increase. This has the disadvantage that the amount of work required by the driver increases due to the increase in the number of drivers and the tediousness of the switching operation.
