Problems solved by technology

Since the spark plug is installed in the ignition chamber, the flow field environment where the spark plug of the rotary engine is located changes from a high-speed unidirectional flow to a low-speed eddy current, which overcomes the problem that the ignition energy is easily lost

Abstract

The invention provides a jet control ignition plug of a rotary engine, the jet control ignition plug is used to be installed on the engine cylinder, the jet control ignition plug includes an ignition chamber, a main intake pipe and a jet pipe, and the ignition chamber passes through The main air intake pipe and the jet pipe communicate with the combustion chamber of the engine, and the main air intake pipe is provided with a valve, which is opened and closed by a slider crank mechanism; a spark plug is installed in the ignition chamber. The main air intake pipe is a curved pipe, and the main air intake pipe is located in the middle of the premixing chamber, and several jet pipes are symmetrically distributed around the main air intake pipe. One end of the connecting rod is hinged to the valve, and the other end of the connecting rod is hinged to the slider, and the actuator moves the slider linearly to open and close the valve. The invention facilitates the mixed gas in the cylinder to enter the ignition chamber, so that the flow field environment where the spark plug of the rotary engine is located changes from a high-speed unidirectional flow to a low-speed eddy current, which overcomes the problem that the ignition energy is easily lost.

Description

technical field [0001] The invention relates to the technical field of power machinery systems, in particular to a jet control spark plug of a rotary engine. Background technique [0002] As a novel internal combustion engine, the rotary engine has the advantages of simple structure, few parts and high power-to-weight ratio, so the rotary engine is widely used in many fields. However, although the rotary engine has a series of superior performances, it also has the serious defect of poor fuel economy. Therefore, it is imperative to improve the combustion efficiency of the rotary engine. The key to improving the combustion efficiency of a rotary engine is to make the fuel burn more quickly and fully in the cylinder. As we all know, the combustion process in the cylinder of a rotary engine is largely restricted by the flow field in the cylinder. Regarding the flow field in the cylinder of the rotary engine, the unidirectional rotation of the rotor of the rotary engine cause...
