Abstract
An internal combustion engine in which it can be made difficult for bubbles to mix into oil in a flowing-down process of the oil. In a generator chamber, a shielding rib is provided which is disposed between a generator and an oil introduction port in side view and which extends skewly upwardly from the oil introduction port in a manner so as to cover one end side of the oil introduction port. A guide rib extends from a side wall of the generator chamber in the manner of covering the other end side of the oil introduction port.
Claims20
An internal combustion engine comprising:
- a generator chamber provided at a side part of a crank chamber and in which a cam chain and a generator are disposed;
- and
- an oil sump chamber including an oil introduction port for receiving a lubricating oil coming from said generator chamber for reserving said oil received through said oil introduction port, with the generator being disposed on the upper side of one end side of said oil introduction port, and with a side wall of said generator chamber extending on the upper side of the other end side of said oil introduction port;
- wherein said generator chamber includes a shielding rib disposed between said generator and said oil introduction port in a side view, said shielding rib extending skewly upwardly from said oil introduction port in a manner so as to cover one end side of said oil introduction port, and a guide rib extending from said side wall of said generator chamber in a manner so as to cover the other end side of said oil introduction port.
An internal combustion engine comprising:
- a generator chamber formed in a crank chamber;
- a cam chain and a generator being operatively mounted within said generator chamber;
- an oil sump chamber formed in a lower portion of said generator chamber;
- an oil introduction port in communication with said oil sump chamber, said oil introduction port receives lubricating oil coming from said generator chamber for supplying the oil to the oil sump chamber, said generator being disposed on the upper side of one end side of said oil introduction port, and with a side wall of said generator chamber extending on the upper side of the other end side of said oil introduction port;
- a shielding rib formed in said generator chamber, said shielding rib being disposed between said generator and said oil introduction port in a side view, said shielding rib extending skewly upwardly from said oil introduction port to cover one end side of said oil introduction port;
- and
- a guide rib formed in said generator chamber, said guide rib extending from said side wall of said generator chamber for covering a second end side of said oil introduction port.
