Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0024] Such as figure 1 A cross-sectional view of a spark plug and fuel injector of an ignition system of an internal combustion engine is shown, showing an embodiment of the present invention installed in a cylinder 10 of the internal combustion engine. In the sectional view of the combustion chamber portion 19 in the cylinder 10, the opposed first electrode 15A and the second electrode 15B are installed on both sides and extend toward each other. The first electrode 15A and the second electrode 15B are separated from each other by a distance determined by the spark gap 17 . The first electrode 15A and the second electrode 15B respectively correspond to a complete first fuel delivery pipe 5A and a second fuel delivery pipe 5B. The fuel delivery pipe is electrically conductive and contains a f...

Abstract

The invention discloses an internal combustion engine ignition system comprising a pair of electrodes which is arranged in a combustion chamber of the internal combustion engine. The electrodes are spaced from each other to form a spark gap. Each electrode is integrated on a fuel transmitting pipe and arranged at the end of the fuel transmitting pipe respectively. Capillary pipelines are arranged inside the oil transmitting pipe to enable the fuel to pass through. A plurality of nozzles are arranged at the ends of the fuel transmitting pipe close to the electrodes, are connected with the capillary pipelines, and are used for spraying the fuel to the combustion chamber close to the spark gap. The internal combustion engine ignition system has the advantages that larger sparks can be produced, and the sparks can be produced at the geometric center of a cylinder to obtain more complete combustion, so as to improve engine efficiency.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to an ignition system of the internal combustion engine. Background technique [0002] Conventional internal combustion engines are equipped with a spark plug, which contains two electrodes. A power supply electrode is installed in the insulating sleeve, and one end of the electrode extends into the cylinder. A ground electrode is installed opposite the supply electrode gap. These spark plugs are one-piece because both electrodes are in a single unit. [0003] In some instances, spark plugs have been combined with fuel injectors that inject fuel through a nozzle into the air gap portion of the spark plug. This type of combination is also one-piece, since its spark plug and fuel injector are in a single unit. [0004] In each instance, the location of the spark produced by the arc within the combustion chamber is limited by the relatively short length of the spark plug that protru...
