    Abstract: A variable valve timing and lift system comprises a camshaft having a rotary cam and a valve operating (VO) cam, and a control rod having an integral portion. The integral portion in the form of an eccentric cam supports a rocker arm. The rotary cam is fixed to the camshaft. The VO cam is in contact with a valve lifter for a cylinder valve of an engine. A torsion spring winds about the camshaft to apply a bias to the VO cam. The rocker arm has a first arm cooperating with the rotary cam and a second arm cooperating with a projecting radial lever of the VO cam. Under the action of the torsion spring, the lever of the VO cam is held in engagement with the second arm of the rocker arm and the second arm of the rocker arm is held in engagement with the rotary cam.

    Abstract: In a working 4-cycle engine including a crankcase, a cylinder block inclined with respect to the crankcase, and an oil pan located in a lower portion of the crankcase. An auxiliary oil tank is disposed below the cylinder block in the direction of inclination of the cylinder block. The auxiliary oil tank communicates with the inside of the oil pan and normally assumes a position higher than the level of oil stored in the oil pan. However, when the engine is tilted down in the direction of inclination of the cylinder block, the oil stored in the oil pan flows into and is accumulated in the auxiliary oil tank. Thus, even if the engine is tilted down in the direction of inclination of the cylinder block, the oil stored in the oil pan is prevented from flowing into the cylinder.
