Title:
INDUSTRIAL VEHICLE
Document Type and Number:
Japanese Patent JP2022095091
Kind Code:
A
Abstract:
To provide an industrial vehicle which can reduce an exhaust odor by oxidizing a prescribed component of unburnt fuel contained in an exhaust gas by using an oxidization catalyst in a full-use region of an internal combustion engine even if an outside air temperature is low.SOLUTION: A hydraulic load control part for controlling a hydraulic load of an internal combustion engine includes: a machine base load requirement rotation number acquisition part for acquiring a machine base load requirement rotation number on the basis of an intake temperature; a rotation number determination part for determining whether or not a rotation number of the internal combustion engine is equal to or smaller than the machine base load requirement rotation number; and a floor temperature determination part for determining whether or not a floor temperature of an oxidization catalyst is equal to or lower than a prescribed floor temperature lower limit threshold at which the oxidization of a prescribed component of unburnt fuel is started. When the rotation number of the internal combustion engine is determined to be equal to or smaller than the machine base load requirement rotation number, and also when the floor temperature of the oxidization catalyst is equal to or lower than the floor temperature lower limit threshold, the hydraulic load control part sets a supply quantity of a working fluid to a hydraulic load generation part by a flow rate variable device on the basis of the rotation number of the internal combustion engine and the intake temperature, and controls the hydraulic load of the internal combustion engine so as to be increased.SELECTED DRAWING: Figure 1
