Hub motor engine combustion

There are several forms of design, construction and arrangement of the engine combustion cylinder interna.

Illustration of three types of configurations: a: in-line engine (L) b: hub motor (V), c: VR6 engine.

Votre engine layout is the V. It cylinders are grouped in two banks or rows of cylinders forming a V which converge on the same crankshaft. In these engines the intake air is sucked inside the V and the exhaust gases expelled from the sides.

Used engines from five cylinders, especially in front wheel drive cars, as it shortens the length of the hub motor in half. The opening of the V varies from 54 º or 60 º to 90 º or 110 º but the most common are 90 º and 60 º. Volkswagen VR6 engine is a V6 only 15 ° opening, which allows slightly reduce the length of the engine (transverse arrangement).

Engines with V available in most common are:
V6
V8
V10
V12
There are also, although very rare, V5 engine. For example, the 2.3 Seat Toledo second generation engine mounts V5.

inline engine Lel (L) is usually available in configurations from 4 to 8 cylinders, the engine is an online all cylinders aligned in a row, without movement.

oposiciónExisten cylinders in three different types of engines with cylinder opposition, commonly referred to the English term flat-cylinder engine:

1.The Boxer
2.la V-180,
3.The cylinder horizontally opposed engine.
Erroneously tend to speak either of these three types of engine cylinders in opposition or confused. In Germany, the term boxermotor is a group in which the boxer motor and motor with V at 180 ° are taken as a provision.

Diagram cylinder boxer engine opposition, first patented by Karl Benz in 1896.El boxer engine is used in the Volkswagen Beetle, Volkswagen Kombi, the Porsche 911, and is currently used by Subaru (in the Impreza, Legacy, etc.). and are usually between 4 and 6 cylinders.

The V-engine 180, configuration very similar to the boxer engine is used by some special editions of Ferrari and Alfa Romeo. The basic difference is that occasionally the engine with V at 180 ° do not use a stump long as the boxer, but the connecting rods share the same position on the crankshaft, making as a piston on the crank the other away, opposite of what happens in the Boxer in which the pistons move away and come together. The 180 ° V engine is used more than 8 cylinders where it has been more effective, while the boxer is used in pairs with less than 6 cylinders and therefore have partnered each other as the same type of disposition.

The engine cylinder horizontally opposed boxer another name.
The advantage of these three types of engines with cylinders in opposition is that they have a lower height and center of gravity lower than that of their peers online and “V” has a more compact, and its elements to be shorter guarantee stability. The main disadvantage Boxer engine is the most cost development and manufacturing because it requires greater number of parts.

Boxer engines are mounted on motorcycles as well as cars. Has been set in the entire series of BMW motorcycles and Ural motorcycles

Meanwhile, and less exclusive, the horizontally opposed cylinder engines have been used since the late thirties in thousands of small aircraft and suffered minor improvements like all piston engines, such as the injection system or the ever more efficient supercharger systems, however, are engines with a configuration of the cylinder head valve (OHV) and a relatively low compression (6.6:1 usually) compared to modern automotive engines, as they are used under other such conditions, likewise, there were no aircraft engines with variable geometry turbocharger and has been developing since the mid-eighties for cars and diesel power in these engines is experimental.

radial or star form this group are two types of engines, both with radial arrangement of cylinders: radial engines and rotary type engines, both used primarily in aircraft engines as static engines. The difference is that radial engines maintain the fixed block, turning the crank on the inside, while the rotary type, the crankshaft remains fixed and the entire block that road.

How is the arrangement HTambién H, which is a sort of hybridization of two-cylinder engines as opposed to using two crankshafts, leaving a bench above the other to generate power for a single axis transmission medium between the two crankshafts.
Form W WOTRO is available which is a kind of double V combined into three or four banks of cylinders and a crankshaft, which dates from the 1920s, and are used in some modern vehicles of the Volkswagen Group, such as Audi A8, Volkswagen Touareg and Volkswagen Phaeton.
