An engine comprising: an exhaust manifold that collects exhaust gases discharged from a plurality of cylinders; a first turbocharger and a second turbocharger, the second turbocharger including a turbine that is configured to rotate by using exhaust gas from the exhaust manifold and the first turbocharger including a turbine that is configured to rotate by using exhaust gas from the second turbocharger, a valve cover that covers all of a plurality of valves for air intake or air discharge to or from the cylinders; a plate-like cover that covers the valve cover; and a fuel tube arranged in a space between the valve cover and the plate-like cover, the fuel tube allowing a fuel to flow therethrough, the plate-like cover being provided with a first partition for catching splashing fuel that extends toward the valve cover and is arranged so as to separate, in an engine width direction, a side where the exhaust gas flows immediately after being discharged from the exhaust manifold from a side where the fuel tube is arranged, the valve cover being provided with a second partition for catching splashing fuel that extends toward the plate-like cover and is arranged so as to separate, in the engine width direction, the side where the exhaust gas flows immediately after being discharged from the exhaust manifold from the side where the fuel tube is arranged, wherein the first partition is formed so as to extend from one end to the other end of the plate-like cover with respect to a crank axis direction, wherein the second partition is formed so as to extend from one end to the other end of the valve cover with respect to a crank axis direction, wherein the second partition has a height that occupies half or more of the distance between the valve cover and the plate-like cover, wherein the first partition is arranged near the second partition and on the fuel tube side relative to the second partition, wherein the first partition and the second partition are arranged so as to separate a side where the second turbocharger is arranged from the side where the fuel tube is arranged, wherein the first and second partitions (11, 42) are in different positions in the engine width direction and are arranged to overlap when seen in the engine width direction, wherein a gap is formed between the first partition and the second partition in the engine width direction, and wherein the first partition is arranged closer to the fuel supply pipe than the second partition. an exhaust manifold that collects exhaust gases discharged from a plurality of cylinders; a first turbocharger and a second turbocharger, the second turbocharger including a turbine that is configured to rotate by using exhaust gas from the exhaust manifold and the first turbocharger including a turbine that is configured to rotate by using exhaust gas from the second turbocharger, a valve cover that covers all of a plurality of valves for air intake or air discharge to or from the cylinders; a plate-like cover that covers the valve cover; and a fuel tube arranged in a space between the valve cover and the plate-like cover, the fuel tube allowing a fuel to flow therethrough, the plate-like cover being provided with a first partition for catching splashing fuel that extends toward the valve cover and is arranged so as to separate, in an engine width direction, a side where the exhaust gas flows immediately after being discharged from the exhaust manifold from a side where the fuel tube is arranged, the valve cover being provided with a second partition for catching splashing fuel that extends toward the plate-like cover and is arranged so as to separate, in the engine width direction, the side where the exhaust gas flows immediately after being discharged from the exhaust manifold from the side where the fuel tube is arranged, wherein the first partition is formed so as to extend from one end to the other end of the plate-like cover with respect to a crank axis direction, wherein the second partition is formed so as to extend from one end to the other end of the valve cover with respect to a crank axis direction, wherein the second partition has a height that occupies half or more of the distance between the valve cover and the plate-like cover, wherein the first partition is arranged near the second partition and on the fuel tube side relative to the second partition, wherein the first partition and the second partition are arranged so as to separate a side where the second turbocharger is arranged from the side where the fuel tube is arranged, wherein the first and second partitions (11, 42) are in different positions in the engine width direction and are arranged to overlap when seen in the engine width direction, wherein a gap is formed between the first partition and the second partition in the engine width direction, and wherein the first partition is arranged closer to the fuel supply pipe than the second partition.
