| 摘要 |
The invention solves the problem of improving the preparation of an air-fuel mixture for the combustion processes thereof by its additional whirling and gasification. The method according to the invention consists in the creation of turbulence and gasification of the mixture by exhaust gases collected directly from the combustion chamber of the engine cylinder in which a working stroke is being performed, whereby the flow to the co-operating cylinder in which a suction stroke is being performed is controlled by the duration of opening the suction valve. The system for the creation of turbulence and gasification of the air-fuel mixture according to the invention has conduits (10, 14) connecting alternately a combustion chamber (9, 13) of a cylinder (1, 2) with exhaust ducts (22) in faces of seats (12, 16) of suction valves (3, 5), whereby the inlets of the conduits (10, 14) are provided with an insert (17) with a throttle nozzle (18) or with an insert (19) with more than one throttle nozzle (20). The invention can be applied in spark-ignition four-stroke internal combustion engines with an even number of cylinders. |
