SULFUR-COMPONENT-REMOVING DEVICE FOR INTERNAL COMBUSTION ENGINE

WIPO Patent Application WO/2009/148186

A1

Disclosed is a sulfur-component-removing device (20) including a desulfurizing layer (23) which is disposed in an engine fuel passage (14) and which removes sulfur-containing compounds from fuel, and an impurity-removing layer (22) which is disposed on the upstream side of the desulfurizing layer in the engine fuel passage and which is able to remove impurities of larger particle size than sulfur-containing compounds from the fuel. The desulfurizing layer and impurity-removing layer are constituted in such a way that the fuel flowing through the engine fuel passage always passes through the impurity-removing layer before flowing into the desulfurizing layer. As a result, a drop in the function of removing sulfur-containing compounds is unlikely to occur even if a fuel or a lubricant containing impurities other than sulfur-containing compounds passes through the device.
