These included the automotive FMC suspension arm, [54] which was innovatively engineered to meet and exceed the performance, weight and cost targets of the production forged aluminum wishbone arm. The design and fabrication process were patented [ 55 ] and showcased also at the automotive SPE conference in April 2021. [ 56 ]
The incentive was cost. Engineering out the four-cylinder's block liners would save $8 per unit — a substantial amount of money at the time. Reynolds Metal Co. developed a hypereutectic aluminum alloy called A-390, composed of 77% aluminum, 17% silicon, 4% copper, 1% iron, and traces of phosphorus, zinc, manganese, and titanium.
A short block is the preferred replacement component for a worn-out engine that requires major servicing beyond the capabilities of a local repair garage, when instead a machine shop may be needed. The short block represents the major wear items of an engine: piston rings, and potentially a rebore of the cylinder bores or replacement liners ...
The Toyota GR engine family is a gasoline, open-deck, piston V6 engine series. The GR series has a 60° die-cast aluminium block and aluminium DOHC cylinder heads.This engine series also features 4 valves per cylinder, forged steel connecting rods and crankshaft, one-piece cast camshafts, a timing chain, [1] and a cast aluminium lower intake manifold.
The 1973–1974 L82 was a "performance" version of the 350 that still used the casting number 624 76cc chamber "2.02" heads but with a Rochester Quadra-jet 4bbl carburetor and dual-plane aluminum intake manifold, the earlier L46 350 hp (261 kW) 350 hydraulic-lifter cam, and 9.0:1 compression forged-aluminum pistons producing 250 hp (186 kW ...
Reducing weight has resulted in using aluminum-silicon alloys more frequently for the engine block in small-displacement engines. Engine blocks of comparable design, but using Al-Si alloys, are not lighter than cast iron engine blocks in the same ratio as that for the specific weights of the materials.
LONDON (Reuters) -An Australian computer scientist who falsely claimed he invented bitcoin was sentenced for contempt of court on Thursday for bringing a 911 billion-pound ($1.2 trillion) lawsuit ...
The engine utilized a water-cooled aluminum block. The main bearing caps were made of ductile iron and held in place with two bolts each. The cylinder block bores had interference fit cast iron liners for the piston rings to sit against. The engine block was made from 319.1 aluminum alloy and the liners were made from grey iron.
