AI Technical Summary
Technical Problem
In bi-fuel internal combustion engines, the difference in consumption current values between gaseous and liquid fuels leads to unnecessary power generation, deteriorating fuel efficiency when a single threshold is used for determining power generation.
Method used
A power generation control device that adjusts the threshold for power generation based on the type of fuel used, setting a first threshold for liquid fuel and a second threshold for gaseous fuel to prevent unnecessary power generation.
Benefits of technology
Improves fuel efficiency by preventing unnecessary power generation and maintaining stable power output when switching between fuels.

Abstract
To provide a power generation control device for a bi-fuel vehicle that can improve fuel efficiency by preventing unnecessary power generation. [Solution] The system includes an engine 11 that can switch between a first fuel F1 and a second fuel F2 having different fuel characteristics, a generator 51 that generates electricity using the output of the engine 11, a battery 13 that is charged by the electricity generated by the generator 51, a pump motor 23, a solenoid valve 27, a regulator 29, a spark plug 30, a starter 50, and an electrical load 55 of the electrical system that are powered by the battery 13, and a control unit 15 that controls the system so that when the engine 11 is driven by supplying the first fuel F1, power generation is performed when the current value of the current supplied from the battery 13 is equal to or greater than a first threshold, and when the engine 11 is driven by supplying the second fuel F2, power generation is performed when the current value of the current supplied from the battery 13 is equal to or greater than a second threshold different from the first threshold.
