Abstract
This fuel property determination device determines components of liquefied natural gas stored in a tank as a fuel for an engine. The fuel property determination device has: an estimation unit that estimates the methane number of the liquefied natural gas using a first estimation method when the engine is being driven, and estimates the methane number of the liquefied natural gas using a second estimation method different from the first estimation method when the engine is to be restarted from a stopped state; and a control unit that controls a notification device so as to provide a notification indicating that a property change has occurred in the liquefied natural gas, if the methane number of the liquefied natural gas estimated by the first or second estimation method is less than a threshold.
