Abstract

The invention provides a rotor engine internal ignition device. The device comprises a rotor engine rotor, a cylinder body and an end cover, the rotor engine rotor is installed in the cylinder body, the end cover is fixed to the end face of the cylinder body, an internal sparking plug is installed in the rotor engine rotor, and the internal sparking plug is communicated with an electrifying device. The electrifying device comprises a first conductive device and a second conductive device, the second conductive device is installed on the surface of the end cover, the first conductive device isinstalled on the end face of the rotor engine rotor, the first and second conductive devices contact to be communicated by the rotation of the rotor engine rotor, the second conductive device is connected with a power supply which is used for allowing the internal sparking plug to operate, the first conductive device is communicated with the internal sparking plug and used for allowing the internal sparking plug to ignite a combustion chamber. According to the device, the purpose of the internal ignition of the rotor engine is achieved through the controlling of the rotor and the contacting piece of a cylinder wall, the defect of incomplete combustion of the rotor engine is overcome, and the performance of the rotor engine is effectively improved.

Description

technical field [0001] The invention relates to the field of rotary engines, in particular to an ignition device inside the rotary engine. Background technique [0002] In the field of internal combustion engines, the energy of fuel combustion will be converted into: external work, vaporization potential and various heat losses, so the fuel cannot be completely converted into external work. How to convert fuel into external work as much as possible has become one of the goals of internal combustion engine designers. For internal combustion engines, incomplete combustion will make the engine work unstable, the output power will decrease, and it will cause serious emission exceeding the standard, and even cause damage to the catalytic converter. The degree of complete combustion of internal combustion engine fuel directly affects the amount of heat generated and the composition of exhaust gas, and the timing of combustion is related to the degree of heat utilization. Therefo...
