Question: How many cylinders does the engine in an Aeroprogress T-411 Wolverine have?
Context: The Krunichev T-411 Aist (en: "Stork") is a Russian light utility monoplane designed by the Russian company Aeroprogress and placed into production by the Khrunichev State Research and Production Space Center.  A version is marketed in the United States as the Aeroprogress T-411 Wolverine powered by a Continental TSIO-550-B. 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. A V4 engine is a type of four-cylinder engine, a V engine with four cylinders.  A V4 engine typically has three main bearings. Usually one bank of cylinders will comprise cylinders # 1&3, and the other bank # 2&4.  For reasons of packaging, the Honda VFR1200 has a 1&4, and 2&3 layout. The inline-four engine or straight-four engine is a type of inline internal combustion four-cylinder engine with all four cylinders mounted in a straight line, or plane along the crankcase.  The single bank of cylinders may be oriented in either a vertical or an inclined plane with all the pistons driving a common crankshaft.  Where it is inclined, it is sometimes called a slant-four.  In a specification chart or when an abbreviation is used, an inline-four engine is listed either as I4 or L4 (for "longitudinal", to avoid confusion between the digit 1 and the letter I). In aviation, an inline engine is a reciprocating engine with banks of cylinders, one behind another, rather than rows of cylinders, with each bank having any number of cylinders, but rarely more than six. The Continental IO-550 engine is a large family of fuel injected six-cylinder, horizontally opposed, air-cooled aircraft engines that were developed for use in light aircraft by Teledyne Continental Motors.  The first IO-550 was delivered in 1983 and the type remains in production. A flat engine is an internal combustion engine with horizontally-opposed cylinders.  Typically, the layout has cylinders arranged in two banks on either side of a single crankshaft and is otherwise known as the boxer, or horizontally-opposed engine.  The concept was patented in 1896 by engineer Karl Benz, who called it the "contra engine." A V6 engine is a V engine with six cylinders mounted on the crankshaft in two banks of three cylinders, usually set at either a 60 or 90 degree angle to each other.  The V6 is one of the most compact engine configurations, usually ranging from 2.0 L to 4.3 L displacement (however, much larger examples have been produced for use in trucks), shorter than the inline 4 and more compact than the V8 engine.  Because of its short length, the V6 fits well in the widely used transverse engine front-wheel drive layout. The Washington T-411 Wolverine is an American homebuilt aircraft that was produced by Washington Aeroprogress of Seattle, Washington, introduced in the 1990s.  When it was available the aircraft was supplied as a kit or in the form of plans for amateur construction. In a reciprocating piston engine, the stroke ratio, defined by either bore/stroke ratio or stroke/bore ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke.  This can be used for either an internal combustion engine, where the fuel is burned within the cylinders of the engine, or external combustion engine, such as a steam engine, where the combustion of the fuel takes place "outside" the working cylinders of the engine.
Answer: six-cylinder
