Definitions

  • the present invention relates to an internal combustion engine, and more particularly to a twin-screw internal combustion engine. Background technique
  • the well-known engines are reciprocating piston type. This type of engine has a long history and is experienced in manufacturing and use.
  • the reciprocal mechanical deficiencies such as complex structure, the need for complex gas distribution mechanism, vibration and noise, such as the conventional four-stroke piston internal combustion engine, the main shaft of the four revolutions per revolution is only one turn, The other three revolutions are consuming power, so it has the disadvantages of large torque variation and low efficiency.
  • the object of the present invention is to overcome the above-mentioned shortcomings of the prior art, and to provide a rotary twin-screw internal combustion engine which has no idle travel, at least two work per revolution, no complicated valve train, no vibration, and easy implementation.
  • the invention consists of a twin-screw compressor, a twin-screw expander, a combustion chamber and a cooling and lubricating system.
  • the twin-screw compressor and the twin-screw expander are coaxially integrated, or are composed of two separate parts, and have a cooling passage in the center.
  • the front and rear parts are separated by a combustion chamber partition, and each of the two slots of the twin-screw expander has a residual helical spiral groove.
  • the mixed gas enters the spiral groove of the suction compression chamber of the twin-screw compressor, and enters the combustion chamber after being heated and heated.
  • the twin-screw expander After being closed, it is ignited and burned into high-temperature and high-pressure gas by the ignition mechanism, thereby pushing the twin-screw expander to make a rotary motion through the shaft head.
  • the expansion machine expands the spiral groove and rotates through the combustion chamber, the residual spiral groove and the combustion chamber are connected to discharge the high-pressure residual gas in the combustion chamber.
  • a certain amount of lubricating oil enters the spiral groove of the suction chamber of the twin-screw compressor through the suction port, and is discharged from the expansion spiral groove of the twin-screw expander through the combustion chamber to lubricate and cool each channel, combustible mixture and lubricating oil. Rotate through each other, rotate work and lubricate the cooling channels, and continue to work to make the engine work.
  • the coolant is cooled from the center of the twin-screw anode and the rotor and the combustion chamber partition.
  • the invention has the following effects: 1. Since the twin-screw internal combustion engine has a plurality of working chambers on the circumference, the work can be performed multiple times in each revolution, and the intake process, the expansion work process, and the exhaust process are separated from each other, so that a complicated gas distribution mechanism is not required.
  • the structure is simple and easy to implement, and since there is no reciprocating air travel, the vibration is small and the resistance loss is small.
  • twin-screw compressor and the twin-screw expander are similar in structure and coaxial in the whole, the structure is simplified, the parts are small, the volume is small, the efficiency is high, and the rotary motion can realize high-speed operation.
  • Figure 1 is a structural view of the present invention.
  • Figure l a is a cross-sectional view of the combustion chamber of Figure 1.
  • Figure l b is the left side view of Figure 1.
  • Figure 1 c is the right side view of Figure 1.
  • Figure 2 is a diagram of the compression process of the present invention.
  • Fig. 3 is a diagram showing the operation of the ignition instant gas-driven twin-screw expander of the present invention.
  • Fig. 4 is a view showing the exhaust gas remaining in the present invention.
  • the mixed gas enters the combustion chamber 5 of the partition 4 through the suction compression chamber 2 of the compressed air screw 1, and when the compression chamber 2 is rotated through the combustion chamber 5, the ignition mechanism 6 ignites the mixture;
  • the expansion chamber 8 of the expansion screw 7 is just in communication with the combustion chamber 5, and the high-pressure high-temperature gas enters the expansion chamber 8 to push the expansion screw 7 to rotate.
  • the residual gas discharge chamber 9 communicates with the combustion chamber 5, The residual exhaust gas is discharged; as shown in Fig. 4, after the above-mentioned work process is completed, the lubricating oil enters the combustion chamber 5 through the suction compression chamber 2 and is discharged from the expansion chamber 8 to lubricate the respective passages.
  • the work and lubrication processes alternate.
  • Another embodiment is similar to a two-stroke internal combustion engine, in which an appropriate amount of lubricating oil is added to the fuel. During the combustion work, the lubrication process can be omitted, and the mixed gas can be continuously compressed - ignited - work.

Abstract

La présente invention concerne un moteur à combustion interne du type à double vis composé d'un compresseur à double vis (1), d'un détendeur à double vis (7), d'une chambre de combustion (5), d'un mécanisme d'allumage (6) et d'un système de refroidissement et de lubrification (3). Le compresseur à double vis (1) est coaxial et solidaire du détendeur à double vis (7), alors que le compresseur à double vis (1) et le détendeur à double vis (7) sont séparés par des cloisons (4) de la chambre de combustion (5). Un passage de refroidissement (3) est prévu au centre du compresseur à double vis (1), du détendeur à double vis (7) et des cloisons (4) de la chambre de combustion (5). Entre la cannelure de chaque vis d'expansion du détendeur à double vis (7) est prévue une cannelure de vis (9) évacuant les gaz d'échappement. La configuration du moteur à combustion interne de type à double vis est simple et l'admission, la compression, l'allumage et la détente du moteur à combustion interne peuvent être effectués simultanément.
