A protective structure for a fuel pump includes a protector including a connecting wall, a first protective wall, and a second protective wall. The first protective wall and the second protective wall are disposed outside the fuel pump assembled to an internal combustion engine. A standing surface of the second protective wall on a side opposite to a second base end surface in a standing direction of the second protective wall includes a curved surface that is concave on the second base end surface side and that becomes closer to the second base end surface side as the curved surface becomes farther from the first protective wall.

Vehicle engine systems and protectors for such systems are presented. Vehicle engine systems can include one or more engine components associated with an engine. In some embodiments a protector can be attached to an engine system to substantially cover a portion of one or more engine components. The protector can have a shield and a support. In some arrangements, the shield can be operatively connected to two cylinder banks of an engine. The shield can extend over and substantially cover a portion of a fuel line and/or a fuel line connector. In one or more embodiments, the support can include a support end configured to support a vehicle component such as a throttle body.

An intake manifold includes: multiple branch pipes having downstream ends fastened to a front or rear surface of a cylinder head; a main pipe connected to upstream ends of the branch pipes; and a cover including a cover main body attached to an upper surface of a portion of at least one of the branch pipes to define a blow-by gas passage, and a protrusion protruding upward from the cover main body, the portion of the at least one of the branch pipes being adjacent to the cylinder head, wherein the protrusion is spaced apart from the cylinder head in a fore and aft direction such that a fuel line positioned above the downstream ends of the branch pipes is interposed between the protrusion and the cylinder head in the fore and aft direction, the protrusion being positioned to overlap a part of the fuel line as seen from front.

In an internal combustion engine for a vehicle, a fuel delivery pipe (37) is favorably protected from a load of a frontal crash. An intake chamber member (42) positioned in an upper part of an intake manifold (31) is supported by an engine main body (11) via a first support member (50) and a second support member (51) at laterally spaced apart parts of the intake chamber member. A lower part of the intake manifold is connected to a cylinder head of the engine via downstream ends of branch pipes (43) of the intake manifold. The fuel delivery pipe extends laterally between an intake side of the engine main body and the branch pipes.

A pump cover for a fuel pump is located at a position lateral to the fuel pump. The fuel pump is disposed on a cylinder head of an engine. The pump cover includes a plate and a rib. The plate is fixed to a side surface of the engine. The plate extends to a position lateral to the fuel pump disposed on the cylinder head. The rib protrudes from the plate, and is located superjacent to a pump mounting surface defined on the cylinder head.

The present disclosure provides a fuel rail for use with an internal combustion engine. The fuel rail includes a plurality of fingers extending away from the fuel rail. The fingers are configured to interface with adjacent engine parts under crash conditions.

A protective cover assembly for a fuel pump in a motor vehicle includes a hooded cover having a first face and a second face in addition to distal and proximate stud bolts, and a base fastener. The hooded cover defines a plurality of apertures operatively configured to receive a corresponding fastener. The distal stud bolt may be operatively configured to affix a distal end of the hooded cover to a cam carrier. The proximate stud bolt may be operatively configured to affix a middle region of the hooded cover to the cam carrier while the base fastener may be operatively configured to affix a lower portion of the hooded cover to the cam carrier. The proximate stud bolt includes an outer diameter feature which is operatively configured to engage with a plunger region of the pump assembly when the proximate cover assembly is subjected to a load.

The fuel delivery pipe extends laterally between an intake side of the engine main body and the branch pipes.

Some gasoline engines have a high-pressure fuel pump that is driven by a rotating component of the engine such as the camshaft or crankshaft. In the event of a crash, the fuel lines coupled to the engine should remain intact to avoid fuel spillage. It is known in the prior art to provide a separate bracket to provide the protection. However, such bracket is a separate piece that must be separately assembled, coupled to components of the engine requiring mounting holes, and adds to the part count of the engine. By integrating a deflector with a fuel pump component, the bracket is obviated.
