Abstract
The invention relates to a rotating speed control device of a magnetic motor type gasoline engine, belonging to the control field of an engine. The rotating speed control device is characterized by comprising a magnetic motor type gasoline engine, a model engine rotating speed sensor, a model engine rotating speed controller and a throttle steering engine, wherein the model engine rotating speed sensor is installed nearby a rotor of a magnetic motor of the gasoline engine; and the model engine rotating speed controller detects the rotation of a rotor magnet of the magnetic motor through the sensor so that the rotating speed of the gasoline engine is detected. The rotating speed control device captures the rotating speed signals of the rotor magnet of the magnetic motor of the gasoline engine and controls the throttle steering engine through the model engine rotating speed controller and the model engine rotating speed sensor so as to control the rotating speed of the gasoline engine.
Description
Technical field
The present invention is the device that is used to control the petrol engine rotating speed, can utilize model engine rotational speed governor and engine sensor thereof, realizes the rotating speed control to magnetic motor type gasoline engine.Be mainly used in technical fields such as Aero-Space, unmanned plane.
Background technique
With the petrol engine be power such as occasions such as depopulated helicopter and fixed-wing unmanned planes, need petrol engine to keep stable rotating speed.Because petrolic load often changes, so fluctuation can appear in its rotating speed thereupon.In order to reduce the adverse effect of petrol engine rotation speed change, need take measures to make engine speed to keep constant.Traditional engine speed control mode is that code-disc or magnet are installed on engine shaft or fan blade, controls by the rotating speed of sensor engine shaft and to engine throttle.Yet, because design and structural reason,, be difficult to sometimes even can't code-disc or magnet be installed on engine shaft or fan blade for unmanned plane especially depopulated helicopter, make engine speed detection and control and can not realize.The present invention utilizes the magnetic of petrol engine magneto rotor upper magnet, by the rotating speed of commercially available model engine rotational speed governor and sensor magneto rotor thereof, and the throttle steering wheel of control motor.Because magneto rotor and engine shaft are synchronous, the therefore rotating speed that obtains by the detection magneto rotor rotating speed of motor just, thus can be used for the control of engine speed.Compare with traditional control method for engine speed, the present invention need not to change engine shaft or fan blade, has advantage simple, reliable, that easily go.
Summary of the invention
The object of the present invention is to provide a kind of device that is used for the control of magnetic motor type gasoline engine rotating speed.
The invention is characterized in, contain magnetic motor type gasoline engine, model engine speed probe, model engine rotational speed governor and throttle steering wheel.Wherein, the model engine speed probe is installed near the petrol engine magneto rotor, and the model engine rotational speed governor obtains petrolic rotating speed by the rotating speed that detects the magneto rotor magnet, and is used for petrolic rotating speed control.
Common commercially available model engine rotational speed governor is used for the rotating speed control of model airplane methanol engine.Its control principle is the rotating speed that is installed in the magnet on the cooling fan of engine blade by sensor, and controls the throttle of motor in view of the above.Because petrol engine is similar to the external characteristics of methanol engine, therefore can control petrol engine with the model engine rotating speed.
3 magnets are arranged on the petrolic magneto rotor, be used for magnetogenerator generating and pilot spark plug ignition circuit.Because its magnet is big, magnetic is strong,, can be used for the sensor of trigger model motor speed controller fully through theory analysis and actual verification.Because magneto rotor and engine crankshaft are synchronous, so the detected magneto rotor rotating speed of the model engine rotational speed governor rotating speed of motor just.Therefore, detect the tach signal of magneto rotor, can realize rotating speed control magnetic motor type gasoline engine by utilizing the model engine rotational speed governor.
Compare with traditional petrol engine method for controlling number of revolution, the present invention need not to change engine shaft or fan blade, need not to install code-disc or magnet, has advantage simple, reliable, that easily go.Compare with the mode of model engine rotational speed governor detection of engine fan blade upper magnet, the present invention need not to change engine blower and magnet is installed, and directly utilizes petrolic original parts, has to save time, and is quick, easily advantage.
Description of drawings
Fig. 1 is the rotating speed control device of magnetic motor type gasoline engine block diagram.
In Fig. 1,1. petrol engine magneto rotor, 2. petrol engine magne to coil, 3. magneto rotor magnet (N is extremely outside), 4. magneto rotor magnet (S is extremely outside), 5. magneto rotor magnet (N is extremely outside), 6. model engine speed probe, 7. model engine rotational speed governor, 8. throttle steering wheel.
Embodiment
In Fig. 1, petrol engine magneto rotor (1), petrol engine magne to coil (2), magneto rotor magnet (3) (4) (5) they are original parts of magnetic motor type gasoline engine.Model engine speed probe (6), model engine rotational speed governor (7) and throttle steering wheel (8) are the devices that is used for controlling engine speed.
Model engine speed probe (6) is installed in petrolic outside.When magneto rotor magnet (S is extremely outside) (4) rotation process model engine speed probe (6), model engine speed probe (6) detects the existence of magneto rotor magnet (S is extremely outside) (4) and is caught by model engine rotational speed governor (7).Model engine rotational speed governor (7) also is the rotating speed of motor according to the rotating speed of magneto rotor magnet (S is extremely outside) (4), controls throttle steering wheel (8), makes the invariablenes turning speed of motor.
