Abstract: PROBLEM TO BE SOLVED: To provide a fuel supply device capable of suppressing the generation of deposit in a fuel injection valve. SOLUTION: This fuel supply device includes a fuel property detection device for detecting whether the content of the aromatic components of a supply fuel stored in a main fuel tank is higher or lower than a determination value, and a fuel separation device for separating the supply fuel into a low-content fuel and a high-content fuel which have different contents of aromatic components. When the fuel property detection device detects that the content of the aromatic components of the supply fuel is higher than the determination value, the content of the aromatic components contained in the high-content fuel is lowered by lowering the separating capability of the fuel separation device.

Abstract: PROBLEM TO BE SOLVED: To secure NOx absorption capacity of NOx absorbent irrespective of oxygen concentration in atmospheric air or altitude while preventing breakage of NOx absorbent. SOLUTION: NOx storage reduction catalysts 26, 27 are arranged in an engine exhaust gas passage. A pair of exhaust branch pipes 22a, 22b branching off of an exhaust pipe 21 and merging after extending mutually in parallel are formed and a SOx trap catalyst 33 for temporally capturing SOx contained in exhaust gas is arranged in the first exhaust branch pipe 22a. Quantities of exhaust gas flowing through the first exhaust branch pipe and the second exhaust branch pipe are controlled by a first flow rate control valve 38a and a second flow rate control valve 38b. Atmospheric pressure representing oxygen concentration in atmospheric air is detected. Almost whole quantity of exhaust gas is made to bypass a SOx trap catalyst and flow in an NOx storage reduction catalyst when the atmospheric pressure is higher than a predetermined set pressure, and almost whole quantity of exhaust gas is made to flow in the NOx storage reduction catalyst after passing through the SOx trap catalyst when the atmospheric pressure is lower than the predetermined set pressure.
