Question: An eight cylinder engine with the cylinders set at an angle is called what?

Context paragraphs:
Straight-five engine: The straight-five engine or inline-five engine is an internal combustion engine with five cylinders aligned in one row or plane, sharing a single engine block and crankcase.  The justification for a five cylinder engine is that it is almost as compact as an inline-four, and almost as smooth as a straight-six engine.

Eagle Manufacturing Company: The Eagle Manufacturing Company of Appleton, Wisconsin first entered the farm equipment market in 1906 with a 32 hp tractor.  They returned to the marketplace several years later, in 1929 offering a 20-35 Model E. Based on a two-cylinder traction engine design, the engine measured 8.00x9.00 inches in bore and stroke.  A truly massive affair, it was rated at 20 drawbar horsepower and 35 belt-pulley horsepower.  Eagle also built its Model H alongside the Model E from 1926 to 1930.  With an identical 8.00 in bore to the Model E, but a 1.00 in longer stroke at 10.00 inches, the Model H created a brawny 40 hp at the drawbar.  Eagle was one of the first tractor manufacturers to use a 6-cylinder engine.  It switched from 2 cylinders to 6 cylinders in 1930.

EMD SW1200: An EMD SW1200 is a diesel switcher locomotive built by General Motors Electro-Motive Division between January 1954 and May 1966.  Power was provided by an EMD 567C 12-cylinder engine which generated 1200 hp .  Late SW1200s built in 1966 were built with the 567E 12-cylinder engine.  Additional SW1200 production was completed by General Motors Diesel in Ontario Canada between September 1955 and June 1964.

Chevrolet Camaro (first generation): The first-generation Chevrolet Camaro appeared in Chevrolet dealerships in September 1966, for the 1967 model year on a brand-new rear-wheel drive GM F-body platform and was available as a 2-door, 2+2 seat, hardtop (no "B" or center pillar) or convertible with a choice of six-cylinder and V8 power plants.  The first-generation Camaro was built through the 1969 model year.

Straight engine: The straight or inline engine is an internal-combustion engine with all cylinders aligned in one row and having no offset.  Usually found in four, six and eight cylinder configurations, they have been used in automobiles, locomotives and aircraft, although the term in-line has a broader meaning when applied to aircraft engines, see Inline engine (aviation).

Adler Standard 8: The Adler Standard 8 is a large passenger car introduced in 1928 by the Frankfurt auto-maker, Adler.  It was a big eight cylinder “limousine” (saloon) closely modelled on the manufacturer’s Standard 6 which had first appeared in public in October 1926.  However the Standard 8 had a longer 3325 mm wheelbase as well as a 50 mm wider track.  Although it closely resembled the Standard 6, the Standard 8 was larger all round.  The Standard 8 engine had eight cylinders, but individually the cylinder dimensions, at 75 mm x 110 mm , were identical to those on the six cylinder car as well as on the four cylinder with the Adler Favorit which appeared in 1929.

V8 engine: A V8 engine is an eight-cylinder V configuration engine with the cylinders mounted on the crankcase in two sets (or banks) of four, with all eight pistons driving a common crankshaft.  Most banks are set at a right angle (90°) to each other, some at a narrower angle, with 45°, 60°, and 72° most common.

Crankcase: In an internal combustion engine of the reciprocating type, the crankcase is the housing for the crankshaft.  The enclosure forms the largest cavity in the engine and is located below the cylinder(s), which in a multicylinder engine is usually integrated into one or several cylinder blocks. Crankcases have often been discrete parts, but more often they are integral with the cylinder bank(s), forming an engine block.  Nevertheless, the area around the crankshaft is still usually called the crankcase.  Crankcases and other basic engine structural components (e.g., cylinders, cylinder blocks, cylinder heads, and integrated combinations thereof) are typically made of cast iron or cast aluminium via sand casting.  Today the foundry processes are usually highly automated, with a few skilled workers to manage the casting of thousands of parts.

V12 engine: A V12 engine is a V engine with 12 cylinders mounted on the crankcase in two banks of six cylinders each, usually but not always at a 60° angle to each other, with all 12 pistons driving a common crankshaft.  Since each cylinder bank is essentially a straight-six which is by itself in both primary and secondary balance, a V12 inherits perfect primary and secondary balance no matter which V angle is used, and therefore it needs no balance shafts.  A four-stroke 12 cylinder engine has an even firing order if cylinders fire every 60° of crankshaft rotation, so a V12 with cylinder banks at a multiples of 60° (60°, 120°, or 180°) will have even firing intervals without using split crankpins. By using split crankpins or ignoring minor vibrations, any V angle is possible.  The 180° configuration is usually referred to as a "flat-twelve engine" or a "boxer" although it is in reality a 180° V since the pistons can and normally do use shared crankpins.  It may also be written as "V-12", although this is less common.

Northumbrian (locomotive): Northumbrian was an early steam locomotive built by Robert Stephenson in 1830 and used at the opening of the Liverpool and Manchester Railway.  It was the last of Stephenson's 0-2-2 locomotives in the style of "Rocket", but it introduced several innovations.  It was the first locomotive to have the Stephenson type firebox incorporated in the boiler, and having a smokebox the full diameter of the boiler, it therefore had the first true 'locomotive' boiler.  It also had plate frames, a proper tender, and the cylinders set at a relatively low angle to the horizontal, giving smoother running.  The pace of development of locomotive design at the time can be seen by comparing this engine with Stephenson's "Planet", produced later the same year.
