Zero-emission compression ignition type two-stroke rotor machine capable of recycling oxygen and control method thereof

Abstract

The invention discloses a zero-emission compression ignition type two-stroke rotor machine capable of recycling oxygen and a control method thereof, belongs to the field of internal combustion engines, and particularly relates to a control method of a two-stroke rotor machine capable of achieving compression combustion of pure oxyhydrogen fuel and recycling tail gas energy and surplus oxygen. Therotor machine comprises a two-stroke rotor machine fuel supply and combustion strategy and a tail gas energy utilization and oxygen recovery strategy, wherein pure oxyhydrogen fuel in the device directly enters an air cylinder through a hydrogen inlet pipeline and an oxygen inlet pipeline respectively; and heating rods (4) and (31) heat mixed gas according to needs to achieve compression ignitionoperation of the rotor machine. Meanwhile, the device recycles tail gas energy for multiple times through an energy recovery device (20), a heat exchanger (10) and a condenser (17). According to the two-stroke rotor machine provided by the invention, the power density of the rotor machine is effectively improved, and the effects of zero pollution of tail gas and improvement of the energy utilization rate of the whole machine are achieved through pure oxyhydrogen combustion and tail gas energy utilization.

Description

technical field [0001] The invention designs a control method of a zero-emission compression ignition type two-stroke rotor machine that can recover oxygen, and specifically relates to a control method of a two-stroke rotor machine that compresses and burns pure hydrogen-oxygen fuel and recycles tail gas energy and excess oxygen. The field of internal combustion engines. Background technique [0002] Due to its unique geometric design and movement mode, the rotary engine has many advantages compared with the piston engine, such as simple structure, small size, light weight, uniform torque, and stable operation. However, the rotary engine emits more pollutants and has poor intake and exhaust performance The problems of poor performance and large exhaust energy loss cannot be ignored. It can be seen that there are many places to be improved in the rotary engine. [0003] The rotor machine operates in the form of two strokes. From the performance point of view, when the eccent...
