A fuel injector assembly includes a modular fuel injector unit and a cylinder head side member. The modular fuel injector unit includes a first fuel injector with a first seal, a second fuel injector with a second seal and a fuel distribution pipe coupled together as a single installable unit. The cylinder head side member includes a first insertion hole with a first fitting section and a second insertion hole with a second fitting section. The first and second insertion holes and the first and second seals of the first and second fuel injectors are arranged such that as the modular fuel injector unit is being mounted to the cylinder head side member, the first seal undergoes a maximum compressive deformation in the first fitting section at a time that does not coincide with a time that the second seal undergoes a maximum compressive deformation in the second fitting section.

An oil pan for internal combustion engine which is lightweight and has improved stiffness and vibration suppression, achieved by reducing the number of components. The oil pan includes an upper portion to be attached to the bottom portion of a cylinder block directly or through an adaptor plate and a lower portion provided on the bottom of the upper portion, with a baffle plate formed integrally downward of the upper portion. An oil supplying means which sucks the oil accumulated in the lower portion and supplies the sucked oil to portions of the internal combustion engine is provided.

Oil pan for internal combustion engine

The oil pan includes an oil introducing portion that has an oil introducing plate. The oil introducing plate has an insertion hole for receiving a sucking portion of an oil strainer. The oil introducing plate extends from the periphery of the insertion hole toward a side wall of the oil pan. The oil returned from the first oil return passage is introduced to flow along the oil introducing plate via an oil falling hole formed in a baffle plate that is positioned at the bottom of a crank case of the internal combustion engine. The oil introducing portion further includes a plurality of inclined wall portions mounted on a bottom portion of the oil pan in the vicinity of the side wall of the oil pan in order to support the oil introducing plate. Opening portions are formed between the inclined wall portions and the bottom portion of the oil pan. The oil introducing plate of the oil introducing portion is located just below the oil falling hole formed in said baffle plate.

Oil pan of internal combustion engine

An oil pan () is mounted to a lower surface of a cylinder block () in order to reserve an oil. An oil pump housing () is cast integrally with the inner side of the right side surface () of the oil pan (). A rib () is formed in order to connect the right side surface () and a left side surface () of the oil pan ().
