  "textContent": "An engine controller includes a fuel supplier and one or more processors. The one or more processors determine, based on an operation state of an engine, whether an operation point of the engine is in an engine operation range where an amount of surplus fuel to be returned to a jet pump is smaller than a predetermined amount. Upon entry into the engine operation range, the one or more processors obtain an amount of remaining fuel in a sub-tank, based on a travel state of a vehicle, and accumulate an amount of fuel injection after the entry into the engine operation range, to obtain an accumulated amount of fuel injection. When the amount of remaining fuel in the sub-tank is smaller than the accumulated amount of fuel injection, the one or more processors put limitation on maximum torque for each engine speed of the engine.",
