Abstract: An internal combustion engine with a reduced size while securing a sufficient amount of lubricating oil for rocker shafts in the internal combustion engine. A cam holder formed in a cylinder head extends from a rear wall portion of the cylinder head toward the attachment hole, and an intake-side downstream rocker shaft oil supply passage formed in a cross shape by causing two linear portions to intersect each other is formed inside the cam holder. In the intake-side downstream rocker shaft oil supply passage, one of the linear portions communicates with a left intake-side support hole located on a left side and configured to support a left intake-side rocker shaft, while the other one of the linear portions communicates with a right intake-side support hole located on a right side and configured to support a right intake-side rocker shaft.

Abstract: A camshaft-drive tensioner system is disclosed for an internal combustion engine having a camshaft-drive element. The camshaft-drive tensioner system includes a tensioner configured to be energized by a pressurized fluid in order to apply a force to the camshaft-drive element. The camshaft-drive tensioner system also includes a fluid pump configured to supply the pressurized fluid. The camshaft-drive tensioner system additionally includes a controller configured to regulate either volume or pressure of the fluid supplied to the tensioner by the fluid pump to thereby selectively vary the force applied to the camshaft-drive element. An internal combustion engine having such a camshaft-drive tensioner system and a method of selectively varying a force applied to the camshaft-drive element are also disclosed.

Abstract: An engine is described having a crankcase, a liner and a head assembly. The crankcase is split along a plane defining a two part crankcase, where fluid passages are passing through only one of the crankcase portions, so as to not require crossing the split line. A connecting rod also includes a tapered end, and the piston has a complementary carrier receiving the connecting rod.

Abstract: An internal combustion engine includes a camshaft, a cylinder head, a head cover, a high-pressure pump, and a vacuum pump. The high-pressure pump includes a plunger that abuts against a cam provided on the camshaft. The high-pressure pump is configured to be driven by rotation of the cam such that oil that has lubricated abutting portions of the cam and the plunger collides with an inside wall of the head cover. The vacuum pump is mounted to the cylinder head. The vacuum pump is configured to draw in air from an inlet and discharge an oil mist with air from an outlet. The outlet is arranged such that the oil mist with air from the outlet is discharged into a space where an oil mist formed by a spray of oil that has collided with the inside wall of the head cover stagnates.

Abstract: A forward phase of a forward intermediate rotor is adjusted relative to a crank shaft. A forward stopper mechanism prevents further advance of the forward phase by engaging the forward intermediate rotor at a forward most-advanced phase. A forward locking mechanism locks the forward phase when reaching the forward most-advanced phase at a start time of the engine. A forward biasing member biases the forward intermediate rotor in an advance direction. The backward phase of the intake cam shaft is adjusted relative to a backward intermediate rotor by receiving a cam torque that is biased on average in a retard direction. A backward stopper mechanism prevents further retard of the backward phase by engaging the intake cam shaft at a backward most-retarded phase. A backward locking mechanism locks the backward phase when reaching the backward most-retarded phase at the start time of the engine.
