The storage device (74) stores a first mapping that receives, as an input, first input variables including a pump variable, a consumption flow rate variable on a consumption flow rate of the fuel, and a property variable on a property of the fuel, and outputs the fuel pressure variable. The execution device (71) acquires the first input variables and estimates the fuel pressure variable by applying the first input variables to the first mapping.",
