arranged in the form of a cylinder, as the name implies, refers to the respective cylinders arranged in the form of a multi-cylinder internal combustion engine, straightforward to say, is discharged from the queue in the form of an engine on a cylinder. .
1 cylinder arrangement in the form of free
The current mainstream engine cylinders are arranged in the form:
1.L: line
2 .V: V-type arrangement
other non-mainstream cylinder arrangement:
1.W: W type arrangement
2.H: level opposed engine
3.R: rotary engine
2 line (L type) Basic description
As the name implies, is a row of all the cylinders to reciprocate up and down, following the general six-cylinder engine with this way, it is characterized by a simple process low manufacturing cost easy maintenance. It is the preferred economy car, but a large shock when the engine is running.
The basic type 3.H description
The two cylinders are connected to a horizontal manner, all of the pistons to make the level of reciprocating motion, characterized by a balance of the engine is better, and the center of gravity is relatively low, is conducive to the stability of the vehicle. For example, Subaru in the World Rally Championship racing and are based on the famous Porsche boxer engine. But since all the cylinders are horizontally placed, lubricate the upper half became a problem, relative to other types of engines require a more sophisticated lubrication system, invisible to increase the manufacturing cost. H horizontal opposed type (also known as 180 degree angle.
Basic description
type 4.V
all of the cylinders in two rows, corresponding to two in-line cylinders of the engine are connected at a certain angle, the engine is an ideal form, it is characterized by smooth, vibration and noise must be less than in-line engine. Ride affect the size of the angle between the two cylinders of the engine is relatively large, 90 ° is the best, but since the engine manufacturers have other considerations, will have 60 °, 110 ° and other forms, Usually the angle, the smaller the width of the engine, disposed within convenient for small cabin, but to a corresponding increase in the height. The center of gravity angle is increased, then the height of the engine is relatively low, is conducive to stability in the corners of the vehicle body. V-type engine construction is relatively complicated, manufacturing costs and maintenance costs are high, and more used in high-end cars.
The basic type 5.W description
The V-type cylinder engine is then shifted on both sides of a small angle, is W-type launchThe machine. W type engine with respect to the V-type engine, the advantage of the crank may be shorter, the weight can be more lightweight, but will also increase the width of the engine compartment will be more full plug. The disadvantage is divided into two parts on the W-type engine structure, the structure is more complex, in operation will have a great shock, so only a small number of applications in the car.
W-type engine is Volkswagen’s first, but it is not four banks of cylinders arranged in a W-type, four cylinder, but by a complex spatial structure of the small angle between the two V-type engine a crankshaft connected to the same. This can greatly reduce the size of the engine, such as the volume of cylinder W-type engine 12 is only equivalent to the general public or a volume slightly larger V8 V6 engine, while operating very smoothly quiet. But the complexity of the W-type engine configuration other people whom tip the scales, high manufacturing costs it can only be used in some large luxury cars, such as Volkswagen Phaeton 6.0 and the Audi brand’s flagship A8L6.0 are used in W12 engine .
6. The rotary engine of a basic introduction
There is currently widely used in reciprocating piston engines automotive goods. There is a kind of high visibility, but use very little engine, which is the triangle rotary piston engine, which is the rotary engine. Compared common L, V-type cylinder layout form, many of my friends will feel strange triangular rotor engine. The rotary engine is also known as the Miller cycle engine, invented by German Fei Jiashi • Wankel, after the technology was acquired by Mazda. We all know: the traditional cylinder reciprocating motionDynamic engine, when the working piston reciprocating linear motion in the cylinder, and to the linear motion of the piston into rotational movement, the toggle mechanism must be used. Rotary engine is different, it can be directly expansion force of the combustion gas is converted to driving torque. Compared with reciprocating engines, rotary engines cancel unwanted linear motion, and thus the same power of the rotor smaller engine size, light weight, and low vibration and noise, has great advantages.
