    Abstract: An iron-based sintered powder metal article for cam lobe and other high temperature, high wear applications requiring excellent net-shape stability during sintering comprises a powder metal mixture consisting essentially of, by weight, 0.5–3.0% Mo, 1–6.5% Cr, 1–5% V, and the balance Fe and impurities. These articles also have a carburized case having 0.7–1.2% C by weight. Following carburization of the case, the articles are quenched to form a martensitic matrix having a network of disbursed carbides of Cr and V. The resulting sintered articles have good mechanical strength and wear resistance and possess excellent machineability and dimensional stability.

    Abstract: A valve system lifter for combustion engines includes a hard metal face pad connected to a lower-grade metal lifter body. The connecting material is one or more materials that are different from both the lifter body and the face pad. Preferably, the connecting material is a silver- and copper-containing material, that may take the form of a wafer with silver or silver alloy layered over a copper alloy core. The preferred body includes one or more ferrous compounds, and the preferred face includes tungsten carbide. The resulting lifter is resistant to the cracking, breakage, and wear that plague conventional lifters, due to the harsh temperature and impact environment of the lifter. The resulting lifter may be used to reduce the need for change-out and down-time in many engines.

    Abstract: In one aspect, the present disclosure is directed to an internal combustion engine having an engine block defining at least one cylinder and a head connected with said engine block. The head has an air intake port and an exhaust port. The internal combustion engine also has a piston and a combustion chamber. The internal combustion engine further has an air intake valve movable to open and close the air intake port and an air supply system having at least one turbocharger fluidly connected to the air intake port. The internal combustion engine additionally has a fuel supply system operable to inject fuel into the combustion chamber, a cam assembly selectively mechanically linked to the air intake valve to move the air intake valve, and an electromagnetic actuator configured to decouple the cam assembly from the air intake valve and control movement of the air intake valve.
