This engine used cast-iron cylinder liners and a cast-iron head. The cylinder heads for the two types of block (aluminum and cast iron) have similar designs but are not interchangeable. The cylinder head for the aluminum block is roughly 1/8" wider than that for the cast-iron block and uses a slightly different head bolt pattern. [9]
The original price for the 16 hp (12 kW) version was $70 lower (at US$228) than their single-cylinder cast-iron version bearing the same power rating. [ 18 ] Industrial/Commercial (I/C) – This series of engines, initially ranging from 3 to 20.5 hp (15.3 kW), was introduced in 1979 as Briggs & Stratton's answer to high quality commercial-duty ...
Briggs engineers had worked out how to replace the standard heavy cast iron bathtub. They used their expertise in deep draw metal stamping and the machinery for making car fenders. The new bathtub was stackable and about one-quarter of the weight of the cast iron product. The Briggs family kept Beautyware and did not sell it to Chrysler in 1953.
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.
Cylinder head porting refers to the process of modifying the intake and exhaust ports of an internal combustion engine to improve their air flow. Cylinder heads , as manufactured, are usually suboptimal for racing applications due to being designed for maximum 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.
Steel casting is a specialized form of casting involving various types of steel cast to either final/net or near-net shape. Steel castings are used when iron castings cannot deliver enough strength or shock resistance. [1]
A joggle bend in sheet metal (at top of image) and a hand joggling tool Joggling , [ 5 ] also known as joggle bending , is an offset bending process in which two opposite bends with equal angles are formed in a single action creating a small s-shape bend profile and an offset between the unbent face and the result flange that is typically less ...
