Bi-fuel vehicle

摘要

PROBLEM TO BE SOLVED: To realize automatic stop control of an internal combustion engine excellent in starting performance and fuel efficiency performance in a bi-fuel vehicle according to the remaining amount and characteristics of each fuel. SOLUTION: A predetermined automatic stop condition is satisfied with an internal combustion engine (11) capable of using a first fuel (F1) having a relatively high starting performance and a second fuel (F2) having a relatively high fuel efficiency. A bifuel vehicle (10) including an automatic stop control device (12) that automatically stops the internal combustion engine when the internal combustion engine is stopped and restarts the internal combustion engine when a predetermined restart condition is satisfied while the internal combustion engine is stopped. ), And when the internal combustion engine is operating using the second fuel and the remaining amount of the first fuel is equal to or less than the first predetermined value, the automatic stop control device automatically stops the internal combustion engine. Prohibition, if the internal combustion engine is operating using the first fuel and the remaining amount of the second fuel is less than or equal to the second predetermined value, the automatic stop control device permits the automatic stop of the internal combustion engine. , Notifies that the remaining amount of the second fuel is low.
