Balance Shaft Counterweights
Increased customer expectations for smooth running and quiet engines has increased the need for balance shafts – which are added to engines to minimize vibration. Balance shafts made by assembling counterweights, drive gears, and other components onto a tube offer a lightweight and competitive solution.
Camshaft caps, commonly referred to as cam caps, are structural aluminum engine components used to secure a camshaft to the cylinder head. They are commonly found in internal combustion engines where increasing demands and complexity make them ideally suited to the PM process.
The global automotive market for camshafts has been steadily transitioning from solid cast iron camshafts to lighter weight modular assembled camshafts to optimize performance and reduce finishing costs.
Connecting rods, commonly referred to as con rods, are key engine components that are the link between the piston and the crankshaft.
Gears are typically used in engines to drive timing, balance shaft or auxiliary systems. Complex geometry makes these products an ideal application for PM technology. Net or nearest to net shape teeth, weight reduction options and net shape drive features gives PM an advantage over other metal working processes.
Fuel injected engines require a clamp to retain the injector in place. PM technology has proven to be an effective and competitive solution for this application.
Main Bearing Cap
Main Bearing caps are used in piston engines to secure the crankshaft to the engine block. GKN pioneered the PM main bearing cap (MBC), and introduced the nearest to net shape “ready to install” engineered MBC to the market.
Timing Drive Pulleys and Sprockets
Engine pulleys and sprockets are typically used in engines to drive crankshaft and camshaft timing systems. Complex geometry makes these products an ideal application for PM technology. Net or nearest to near net shape teeth, weight reduction features and integrated drive features gives PM an advantage over other metal working processes.
Variable geometry turbochargers (VGT’s) are designed to allow the aspect ratio of the system to adjust to optimum levels depending on engine speeds. A key component in this system is a ring of aerodynamically-shaped, moveable, vanes in the housing at the turbine inlet.
Valve guides are used to improve the performance of Aluminum block engines through the addition of a more wear resistant insert. PM has proven to be the best solution for valve guides through the combination of unique wear resistant and self-lubricating materials, and near net shape geometry.
Valve Seat Inserts
Valve seat inserts are used to improve the performance of Aluminum block engines through the addition of a higher performance steel insert. PM has proven to be the best solution for valve seat inserts through the combination of unique wear resistant and high thermal conductivity materials, and near net shape geometry.
Variable Cam/Valve Timing Components
In order achieve requirements to reduce both automotive fuel consumption and emissions while also increasing performance, systems that optimize camshaft or valve timing are of increasing importance.
