摘要： The invention provides a low tension piston ring having a finished outer diameter and negligible tangential tension. The method includes the steps of machining a stock bar to an initial outer diameter slightly greater than the finished outer diameter of the piston ring, finishing the initial outer diameter of the stock bar to a rounded profile having a nominal diameter equal to the finished outer diameter, and machining the stock bar to the preferred cross-section. Dykes-type piston rings can have keystone or semi-keystone shaped cross-sections. The method continues by detaching the piston ring from the stock bar using a parting tool in response to completing all tension inducing operations including the steps recited above. The method continues with the steps of lapping the piston ring to a final longitudinal thickness and cutting the piston ring longitudinally to form a final gap.

摘要： An engine maintenance kit and multi-use container assembly (28). The multi-use container (28) includes a base (30) and a separable lid (32) that is fitted at its uppermost end with a pour spout (46). A funnel portion (50) is formed integrally in the lid (32) and serves to facilitate the filling of fresh, unused oil from a bottle (24) into an engine (12). The base (30) serves as an oil pan for capturing waste oil (56) during the maintenance process. Following an oil change, the lid (32) is returned to the base (30) for securely transporting the waste oil (56) to an appropriate collection center.

摘要： A vehicle headlamp system includes a headlamp assembly having a light source and a beam pattern panel. The beam pattern panel includes one or more regions capable of changing between opaque and transparent light-transmission states to selectively allow light from the light source to pass through the panel. The panel may be an LCD panel with a plurality of liquid crystal elements arranged in an array with the ability to provide a plurality of different beam patterns. The beam pattern may be determined and changed in real time based on information received at a system processor about one or more vehicle and/or road conditions. The headlamp system can direct a projected light beam into a curve in the road ahead and/or automatically change the direction of the projected beam to avoid shining light directly at oncoming drivers.

摘要： A cylinder head gasket including at least three functional layers and at least two stoppers is provided. The first functional layer includes a first full bead extending around a combustion chamber opening and axially aligned with a second full bead of the second functional layer. The first stopper extends along the first functional layer between the combustion chamber opening and the first full bead for preventing over-compression of the first full bead. The second stopper is located beneath the second full bead of the second functional layer for increasing load on the second full bead, reducing head lift, and promoting an even distribution of the load. The second stopper is not attached to the second functional layer along and adjacent the second full bead, and thus an air gap is present between the second stopper and the second full bead when the gasket is not compressed.

摘要： A piston for an internal combustion engine and method of construction thereof is provided. The piston includes a piston body having an upper combustion surface with a combustion bowl depending from the upper combustion surface. The piston body has a ring belt region configured for receipt of at least one piston ring adjacent the upper combustion surface. A cooling gallery is configured in radial alignment with the ring belt region. An annular combustion bowl rim region extends between the upper combustion surface and the combustion bowl, and a bonded seam extends from the combustion bowl rim region radially outwardly to the cooling gallery. The bonded seam has material properties exhibiting an enhanced ability to withstand the extreme temperature, pressure, stress and highly corrosive and erosive effects of the combustion gases relative to the surrounding material of the piston body.

摘要： A piston with a piston body extending along a longitudinal central axis and having a crown portion and a pair of pin bosses is provided. The crown portion includes a combustion wall with a combustion bowl formed therein and a pair of ribs depending from the combustion wall. One of the ribs depends from the combustion wall directly below the combustion bowl, and the other rib is radially spaced from the combustion bowl. As such, one of the ribs depends lower along the longitudinal central axis than the other of the ribs. The ribs provide support to the crown portion and also act as a heat sink to extract heat from the combustion wall.

摘要： A piston assembly includes a piston having a crown with an upper combustion surface with a cylindrical outer surface extending downwardly from the upper combustion surface. A pair of pin bosses depends from the crown to a pair of pin bores having generally cylindrical bearing surfaces aligned along a pin bore axis with a top wall portion extending between the pin bosses. The top wall portion has a concave bearing surface forming a continuous concave bearing surface with the pin bores. A separate skirt is fixed to the piston against relative movement. At least one rib extends upwardly from the top wall portion of the piston on opposite sides of the pin bore axis to a lower wall surface of the crown. The at least one rib joins the crown to the top wall portion to provide structural support to the top wall portion against unwanted deflection.
