In the past when it was called GM-Saginaw Product Company (SPC) a cloverleaf casting symbol mark was cast onto the iron component. [ 1 ] [ 2 ] The location has been the primary source of engine block and cylinder heads for all of GM's engines, to include Oldsmobile, Pontiac, Cadillac, Chevrolet, Buick and GMC for most of the 20th century.
Changes include a vacuum port to draw filtered air through the distributor to remove moisture and ozone and a revised drive system which uses an extended dowel pin on the camshaft rather than a separate splined shaft in the camshaft gear. 1996 saw major revisions for OBD-II: a second catalytic converter on the F-body cars, rear oxygen sensors ...
In 1933 Mads Clausen (1905–1966) founded Dansk Køleautomatik- og Apparatfabrik, later in 1946 the company name was changed to Danfoss.The first product was an expansion valve for refrigeration units, it was developed after studying imported valves from the US.
Integrated die casting [36] refers to the high-level integration of multiple separate and dispersed alloy parts through a large-tonnage die-casting machine, and then formed into 1–2 large castings. The aim is to reduce manufacturing costs through one-time molding, significantly decreasing the number of parts needed for car assembly and ...
A core is a device used in casting and moulding processes to produce internal cavities and reentrant angles (an interior angle that is greater than 180°). The core is normally a disposable item that is destroyed to get it out of the piece. [1] They are most commonly used in sand casting, but are also used in die casting and injection moulding.
Centrifugal casting is particularly suited as they behave in the manner of shallow flat castings relative to the direction of the centrifugal force. Centrifugal casting is also used to manufacture disk and cylinder shaped objects such as railway carriage wheels or machine fittings where grain, flow, and balance are important to the durability ...

De Dion-Bouton engine with monobloc cylinder heads, but cylinders separate from crankcase c. 1905 [1]. A monobloc or en bloc engine is an internal-combustion piston engine some of whose major components (such as cylinder head, cylinder block, or crankcase) are formed, usually by casting, as a single integral unit, rather than being assembled later.
