Abstract:
An internal combustion engine comprising a cylinder body defining a cylinder bore in which a piston reciprocates, a cylinder head affixed to an end of the cylinder body and defining a combustion chamber with the cylinder head and the piston, a fuel injection system including a fuel injector supplying fuel to the combustion chamber, a fuel reservoir at least temporarily storing the fuel therein, a fuel conduit communicating with at least one of the fuel reservoir and the fuel injector, and a fuel cooling device to cool the fuel passing through the fuel conduit, the fuel conduit including a first fuel supply conduit supplying fuel to the fuel reservoir, a second fuel supply conduit supplying fuel from the fuel reservoir to the fuel injector, and a fuel return conduit returning the excess fuel from the fuel injector to the fuel reservoir, at least one of the first fuel supply conduit, the second fuel supply conduit, and the fuel return conduit carrying the fuel cooled by the fuel cooling device, the fuel cooling device including a jacket having at least two channels, both of the channels juxtaposed to each other, one of the channels defining, at least in part, the corresponding one of the first fuel supply conduit, the second fuel supply conduit and the fuel return conduit, and the other channel defines a coolant conduit through which coolant passes, at least one of the channels having an incomplete partition therein to make the fuel and/or the coolant detour around it.
