摘要： A three-dimensional cam has a cam profile surface shape that changes along a rotating axis of the cam, and is produced by net-shape-sintering. The sintered density of a sintering material at the time of net-shape-sintering is set to 7 to 7.4 g/cm3 to achieve a hole rate of the cam profile surface within the range of 5 to 10%. The three-dimensional cam has an improved durability, while securing high productivity.

摘要： The cam face of an intake cam has a main lift portion, which causes an intake valve to execute a basic lift operation, and a sub lift portion, which assists the action of the main lift portion. The main lift portion and the sub lift portion continuously change in an axial direction of the intake cam. An axial movement mechanism moves the intake cam in the axial direction to adjust the axial position of the cam face that drives the intake valve. The axial movement of the intake cam results in the valve being given a variety of valve lift characteristics in the form of a combination of a cam lift pattern realized by the main lift portion and a cam lift pattern realized by the sub lift portion. Therefore, various engine performances required according to the running conditions of the engine can be fully satisfied by the valve characteristics.

摘要： A variable valve apparatus of an internal combustion engine is capable of realizing more precise valve characteristic control by reducing the error in-detection of the amount of movement of a camshaft caused by a difference in the rate of thermal expansion. The variable valve apparatus has a camshaft that is supported so as to be rotatable and slidable in a direction of an axis thereof and that has three-dimensional cams whose cam profile continuously changes in the direction of the axis. The apparatus also has an actuator for moving the camshaft in the direction of its axis. The apparatus further has a camshaft position sensor provided in a cylinder head, a detected portion provided in the camshaft, and a camshaft movement amount detection portion for detecting the amount of movement of the camshaft in the direction of the axis. The camshaft movement amount detection portion is provided near a camshaft reference position.

摘要： A piston, which reciprocates in a cylinder bore of an engine, is supplied with lubricating oil. The piston includes pin bosses provided under a piston head, a symmetrical pair of skirts, and side walls connecting the pin bosses and the skirts. The side walls have openings, which communicate the outer side of the walls with the inner side of the walls under the middle section of the head. A recess is defined in the lower surface of the head to receive a spray of lubricating oil. The width of the recess is wider than the width of each skirt at its basal portion. This causes the oil supplied to the lower surface of the head during movement of the piston to be injected against the recess and thus be diffused. As a result, oil passes by the basal section of the skirts and permeates into the space defined by the cylinder bore and the skirts.
