Title:
燃料系制御装置
Document Type and Number:
Japanese Patent JP6848689
Kind Code:
B2
Abstract:
To provide a fuel system control device for continuously securing the high filter efficiency of a fuel filter.SOLUTION: In S101, S103, S108, S109, kinetic viscosities KVl(KVj), KVp of fuel is acquired at a plurality of temperatures TMl(TMj), TMp. In S104, temperature characteristics CKT of kinetic viscosities according to components constituting the fuel are selected on the basis of the kinetic viscosities KVl, KVp at the plurality of temperatures TMl, TMp, acquired in S101, S103, S108, S109. In S105, a minimum kinetic viscosity KVm at the cloudy point of fuel is determined as a determined threshold value corresponding to the temperature characteristics CKT selected in S104. In S110, S111, a heater is controlled to heat the fuel filter at the kinetic viscosity KVj of the fuel to be not lower than the minimum kinetic viscosity KVm determined in S105.SELECTED DRAWING: Figure 2
