A method for identifying the position of a drone, an engine, a control device, and a gear plate

Abstract

The invention discloses an unmanned aerial vehicle, an engine, a control device, and a method for identifying the position of a toothed plate. The method for identifying the position of the toothed plate is applied to the control device, and the control device includes a controller; the toothed plate rotates under the drive of the engine. The toothed disc is provided with teeth and missing teeth, including: obtaining the actual single-turn teeth number N of the toothed disc when it is running; starting the generator according to the theoretical single-turn tooth number K of the described toothed disc and the formula, the actual starting tooth number I=actual unit Number of ring teeth N-Theoretical number of teeth in a single ring K+Normal starting number of teeth I 0 ;Start complete. The above tooth plate position identification method solves the problem of inaccurate identification of the ignition or fuel injection position when the engine is running discontinuously at the moment of starting, and it can reduce the engine startup under the conditions of reverse rotation and non-reverse rotation. Start the load of the motor, reduce the weight, and improve the success rate of starting.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to a method for identifying the position of a gear plate. It also relates to a control device. An engine is also involved. A drone is also involved. Background technique [0002] On low-weight aviation UAVs, effective weight reduction and increased aircraft payload have become the primary problems; after the weight of the engine is reduced, the low moment of inertia and high compression ratio cause the motor to require a large torque near the top dead center, causing the starter motor It is difficult to start, and the starting speed is as low as 200, which even causes the engine to appear discontinuous in a single lap (the speed fluctuates in a single lap) or rebound (the top dead center cannot be passed at one time, and the three-phase motor needs to be run again to pass). [0003] For the prior art chainring position identification method, the position of th...

Problems solved by technology

[0005] The purpose of the present invention is to provide a tooth plate position identification method to solve the problem of inaccurate identification of ignition or fuel injection position under the discontinuous operation of the engine at the moment of starting, and to have both reverse rotation and no reverse rotation When the engine is started, the load of the starter motor can be reduced, the weight can be reduced, and the success rate of starting can be improved.
