Jet controlled ignition plug for rotor engine

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 en
