Embodiment Construction

[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described:

[0029] Such as figure 1 As shown, when the rotational speed n of the rotary engine changes from n=0 to n≠0, it is the start-up phase, the air passes through the air filter 1 and the air flow meter 2 sequentially in the intake passage, and the electronic control unit ECU16 receives the intake air flow signal b , and calculate the fuel injection quantity according to the intake air volume and the required equivalence ratio in the start-up process; the electronic control unit ECU16 sends a gasoline flow signal a to supply gasoline fuel through the gasoline tank 7, gasoline filter 6, oil pump 5, and gasoline flow controller 4 To the gasoline nozzle 3 and send a gasoline injection signal c to control gasoline injection to the intake port; gasoline and air form a mixture in the intake port, and as the rotor rotates to the moment when the intake valve opens...

Abstract

The invention designs a throttle-free rotor engine control method, and particularly relates to a throttle-free rotor engine control technology and a hydrogen and gasoline dual-fuel combustion control method. According to the throttle-free rotor engine control method, by eliminating a rotor engine throttle valve device, the hydrogen and gasoline dual-fuel injection strategy of the rotor engine is reasonably regulated and controlled through the output torque and the average indicated pressure cyclic variation coefficient, so that it is guaranteed that the rotor engine stably operates in the throttle-free state. According to the throttle-free rotor engine control method, while the throttling loss of the throttle valve is eliminated and the charge coefficient is improved, the efficient and clean operation of the rotor engine is realized by utilizing the hydrogen fuel injection technology.

Description

technical field [0001] The invention designs a throttleless rotor engine control method, specifically relates to a throttleless rotor engine control technology and a hydrogen and gasoline dual-fuel combustion control method, and belongs to the field of internal combustion engines. Background technique [0002] As a kind of internal combustion engine with a special structure, the rotary engine has broad application prospects in the fields of automobiles and small unmanned aerial vehicles. Compared with the internal combustion engine, the rotary engine cancels the crank connecting rod mechanism, replaces the reciprocating motion of the crank connecting rod through the rotary motion of the triangular rotor, and does not generate reciprocating inertia force. The rotary engine has the advantages of small size, light weight, good high-speed performance, stable operation, and low noise. However, the rotary engine has problems such as low charging efficiency and high emission conten...
