The big-block engines initially used a forged crankshaft with a stroke of 3.975" for the 1965-1967 425 and 400 CID versions; starting in 1968, both the 400 cu in (6.6 L) and the 455 cu in (7.5 L) big blocks used a stroke of 4.25 in (108 mm), with crankshaft material changed to cast iron except in a few rare cases.
Both the connecting rods and the crankshaft are of forged steel. The crankshaft is carried in five main bearings, two more than are in the Standard wet liner inline-four engine used in production TRs. [2] [8] The pistons are of die-cast aluminium, and the compression ratio was set by adjusting the height of the piston crown. Bore × stroke are ...
Series 452 engine in the Deutsches Technikmuseum Berlin. The Cadillac V16 engine is a term that applies to two different Cadillac-designed V-16 automobile engines, an overhead valve 45-degree 452 cu in (7.4 L) model produced between 1930 and 1937, and a 135-degree side valve 431 cu in (7.1 L) between 1938 and 1940.
The crankshaft ran in four bearings [3] The engine unit had bi-axial four-point rubber mountings. [ 4 ] "On the offside are the horizontal carburettor, the manifolds held by brass nuts, the air-cooled dynamo with a belt drive common to the combined fan and impeller and the steering box which has worm and double roller gear.
The B25 Starfire designation was adopted for all markets [4] (Frame and engine numbers being prefixed B25B). [20] The machine gained a full-width 7" front brake, [ 8 ] and larger petrol tanks fitted; 2.5 US gallons (2.1 imp gal) on the US version [ 21 ] and a steel 3.4 imperial gallons (4.1 US gal) on the UK version.
Yamaha started development of the OX66 in 1984 [1] as a design concept for a lightweight and compact Formula Two engine with a wide power band.. At the time of development, both BMW and Honda provided engines for F2 (in the form of the M12/7 inline-four and the RA260E V6 respectively), but Honda's engine yielded superior results despite limited use.
A stronger crankshaft with larger bearings was used to handle the increased power, 12 horsepower (8.9 kW) to the LE's 8 horsepower (6.0 kW). [1] The engine also had a bigger crankcase and cast iron cylinders with steel pushrod tubes and alloy heads. It was mounted in a duplex frame with a single top tube. [5]
