Problems solved by technology

However, its geometric structure (the rotor rotates once and the central shaft rotates three times) makes it possible for the three combustion chambers to complete a working cycle when the central shaft rotates once, resulting in a short intake time and a decline in high-speed performance
The hydrogen airway injection will squeeze the air, resulting in lower inflation efficiency and worse high-speed performance

Embodiment Construction

[0016] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:

[0017] Including: hydrogen enters through the hydrogen storage tank (1), gas pump (2), hydrogen filter (3), hydrogen flow regulator (4) and hydrogen nozzle (5) connected in series on the hydrogen transport pipeline (P1) Intake pipeline (P2); fresh air passes through the intake pipeline (P2) in series: air filter (6), air flow sensor (7), turbocharger (8), intercooler (9) 1. The intake air flow sensor (10) enters the rotor machine, wherein fresh air and hydrogen are mixed before the turbocharger (8); through the main structure of the rotor engine: rotor (11), cylinder block (12), central shaft (13) , spark plug (14), and speed sensor (15) run for one cycle to discharge combustion exhaust gas from exhaust pipe (P3): switch one (s1), switch two (s2); ECU (E), speed sensor to ECU The signal (I1) of (E), the signal (O1) sent by ECU (E) to switch one (S1)...

Abstract

The invention designs a control method of a supercharging type Wankel hydrogen rotor engine, and particularly relates to a control method used for adjusting the gas intake supercharging degree according to the rotating speed of the rotor engine. The output rotating speed signal (I1) of a rotating speed sensor (15) of the engine is used as the basis, the operating condition of the engine is judged,the opening degree of a turbosuperchager (8) is controlled by combining a first switch (S1) and a second switch (S2), and therefore gas intake pressure is controlled, and the good high-speed performance of the rotor engine is achieved.

Description

technical field [0001] The invention designs a supercharged Wankel hydrogen rotor engine, in particular relates to a control method for adjusting intake supercharging according to the rotational speed of the rotor engine, and belongs to the field of internal combustion engines. Background technique [0002] Compared with the traditional reciprocating piston engine, the Wankel rotary engine has the advantages of simple and compact structure, high power-to-weight ratio, and low vibration and noise; at the same time, the hydrogen combustion speed is fast, the combustion quenching distance is small, and the combustion emission is small. It is extremely suitable for combustion in the narrow and long combustion chamber of the rotary engine, so the hydrogen rotary engine is a better choice to replace the traditional fossil fuel reciprocating piston engine. However, its geometric structure (the rotor rotates once and the central shaft rotates three times) makes it so that when the c...
