Description

Star-shaped disk engine and series engine unit thereof

Technical Field

The utility model relates to a multi-cylinder engine's arrangement pattern especially relates to a star type disk engine and series connection engine unit thereof.

Background

1. Differences between single-cylinder and multi-cylinder engines

The multi-cylinder has better power than a single cylinder and also has important functions, the reciprocating motion of the piston of the single cylinder can cause the vibration of a vehicle body, and the relative arrangement of the multi-cylinders can mutually counteract the vibration of the single piston. So now for power and comfort requirements even the worst cars will have three cylinders, typically four, six, eight cylinders, and higher cars such as speed even up to 12 cylinders. Of course, the more cylinder bodies, the better, the more cylinders, the more components (spark plugs, crankshafts, camshafts and valves) and the higher the failure rate, the more the required technology is; therefore, on the premise of ensuring the power, the number of cylinders cannot be increased for technical reasons; the common automobiles are mostly provided with four-cylinder engines and six-cylinder engines.

2. Existing cylinder arrangement

all cylinders are arranged in a row, the size is compact, the application is wide, the cylinders are mostly seen in small-displacement vehicle types, generally, the cylinders are most seen below 2.5L, most of household cars are equipped with engines of the type L3, L4 and L6 (the number represents the number of the cylinders, and the description is omitted below).

The advantages are that: the cost is low, the maintenance is convenient, and the layout of the engine compartment is flexible;

the disadvantages are as follows: the engine has low power and is not suitable for vehicles with more than 6 cylinders.

2) And V type:

the cylinders are divided into 2 groups, the adjacent cylinders are arranged at a certain included angle, the side faces of the cylinders are in a V shape, the driving feeling is qualitative leap relative to the L shape, and the cylinders are suitable for vehicles with the displacement of 3.0L or more, such as V6, V8 and V10;

the advantages are that: the driving feeling is smooth, the vibration and the noise are small during the operation, and the small width of the engine is beneficial to the layout of a multi-cylinder engine;

the disadvantages are as follows: the structure is complex, the later maintenance cost is high, the price of the vehicle to be carried is high (influenced by the discharge tax of China), and the oil consumption is relatively high;

3) w type:

the V-shaped engines are staggered by a small angle, which is equivalent to the superposition of 2V-shaped engines, is originally created by the public company and is only equipped on luxury vehicles such as Binly, Lauslesi, Bucadi and the like, and is commonly W8 and W12.

The advantages are that: the operation is extremely smooth, the engine volume is small, and the weight is light;

the disadvantages are as follows: the structure is complex, the manufacturing cost is extremely high, and the occupied transverse space of an engine compartment is large, so that the layout is not facilitated;

4) horizontal opposed type (H type):

two rows of cylinders are horizontally connected by 180 degrees, pistons horizontally reciprocate, the center of gravity is low, the control is excellent, and the engine is only used by Sbaru and Baoshijie all over the world, which are common in H4 and H6;

the advantages are that: the gravity center is low, the operation and the control are good, and the driving stability is good;

the disadvantages are as follows: high manufacturing cost, high technical difficulty and higher later maintenance cost.

5. Rotor type (R type):

the triangular piston is used for deflecting in the elliptical combustion chamber, the combustion expansion force of combustible gas is directly converted into driving torque, the driving torque is bought and developed by Wankel, German, Maadar company, and represents vehicle models such as Maadar RX7 and RX8, and the vehicle models are stopped for years.

The advantages are that: small volume, small displacement, large power per liter, low vibration and noise;

the disadvantages are as follows: high oil consumption, easy abrasion of oil seal materials to cause air leakage of an engine, and high manufacturing and maintenance difficulty.
