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 controlled ignition plug for a rotor engine. The jet controlled ignition plug is mounted on an engine cylinder and comprises an ignition chamber, a main gas inlet pipe andjet pipes; the ignition chamber communicates with an engine combustion chamber through the main gas inlet pipe and the jet pipes; a valve is arranged on the main gas inlet pipe; the valve is opened or closed through a sliding block-crank mechanism; and a spark plug is mounted in the ignition chamber. The main gas inlet pipe is a bent pipe and is positioned in the centre of a premixing chamber; and a plurality of the jet pipes are symmetrically distributed around the main gas inlet pipe. One end of a connecting rod is hinged to the valve; the other end of the connecting rod is hinged to a sliding block; and a sliding blocks performs linear movement through an executing mechanism so that the valve is opened or closed. According to the jet controlled ignition plug for the rotor engine, the mixed gas in a cylinder enters the ignition chamber conveniently, so that the flow field environment where the spark plug of the rotor engine is positioned is changed from high-speed single-direction flow into low-speed eddy current; and therefore, the problem that ignition energy is easily dissipated is solved.

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...
