Abstract

本实用新型公开了一种内燃发动机点火系统，包括：电磁波源、耦合装置、汽缸和控制单元，其中，所述控制单元，监测当前的内燃发动机转速，并在达到所述内燃发动机转速的点火提前角度时通知电磁波源；所述电磁波源，产生一处于所述汽缸固有频率的范围内的固定频率的电磁波；所述耦合装置，将所述电磁波输入所述汽缸；所述耦合装置的探入汽缸的火花塞接口的部分和汽缸，构成谐振腔，使所述电磁波在汽缸内被谐振放大后产生的电场强度大于发生点火的临界电场强度。本实用新型能够在不改变现有内燃发动机结构的前提下，替代现有内燃发动机高压火花点火系统的火花塞将电磁波有效地耦合入汽缸内，并大大提高射频和电磁波点火的成功机率。 The utility model discloses an ignition system of an internal combustion engine, which includes an electromagnetic wave source, a coupling device, a steam cylinder and a control unit, wherein the control unit is used for monitoring the current rotating speed of the internal combustion engine, and informing the electromagnetic wave source when the ignition advance angle of the rotating speed of the internal combustion engine is reached; the electromagnetic wave source generates an electromagnetic wave with a fixed frequency within the range of a natural frequency of the steam cylinder; the coupling device is used for inputting the electromagnetic wave into the steam cylinder; and the part of the coupling device extends to a spark plug connector of the steam cylinder to form a resonance cavity with the steam cylinder, so that the electric-field strength generated by the electromagnetic wave after resonance and amplification in the steam cylinder is bigger than the critical electric-field strength of ignition. According to the utility model, under the premise of without changing the structure of the conventional internal combustion engine, the spark plug substituting the high-pressure spark ignition system of the internal combustion engine effectively couples the electromagnetic wave in the steam cylinder, and the ignition success ratio of radio frequency and electromagnetic wave can be greatly improved.
