Member) direct drive, and the diesel engine turbine supercharger nozzle ring aperture Electronic Control with position signalling feedback function
Device device, it is possible to achieve turbine supercharger nozzle ring aperture continuously adjustabe, and the real-time opening amount signal of nozzle ring can be fed back
To Engine ECU, closed-loop control is realized.It is by direct current generator, gear drive, angular transducer composition.The actuator knot
Structure is simple, performs reliable, it is possible to achieve Engine ECU is controlled the high precision closed loop of turbine supercharger nozzle ring aperture.Specifically
Technical scheme is as follows：
Turbine supercharger nozzle ring electronic-controlled installation with position signalling feedback function, it is characterised in that：Including straight
Flow motor, gear drive, angular transducer；Direct current generator gear is connected with gear drive, gear drive
Output arm is connected with nozzle ring opening controlling mechanism, and the motor power supply positive pole with engine, motor power supply are negative respectively for direct current generator
Pole connects, the sensor power supply positive pole of angular transducer and engine, sensor ground line, and signal wire is connected；Angular transducer
The output arm anglec of rotation is sensed, and angle signal is fed back into Engine ECU；Angle signal includes but is not limited to PWM
Signal, voltage signal, CAN signal；Pwm signal represents different angle signals from 1%-100%, voltage signal from+0.5V to+
4.5V represents different angle signals, and CAN represents different angle informations with the communications protocol of Engine ECU compiling setting；Hair
Motivation ECU is by realizing that the forward or reverse of direct current generator completes output angle to direct current generator offer forward direction or reverse current
Control, and then by turbine supercharger nozzle ring opening controlling mechanism realize nozzle ring aperture control.
When actuator body breaks down, angular transducer can export special fault-signal and pass to Engine ECU,
Engine ECU is facilitated to carry out fault diagnosis in time.
The angular transducer uses Mai Lai cores company model MLX90360 product.
It is an advantage of the invention that：Turbochargers in Diesel Engines nozzle ring uses electronic-controlled installation, with traditional, pneumatic nozzle
Ring control system is compared, and can be accurately controlled the angle of the unlatching of nozzle ring, and the response time is fast.Turbocharging hair can be improved
Motivation low speed torque, speed operation transient response ability, oil consumption is reduced, reduce discharge, reduce the pre- of cold start-up after-treatment system
The hot time.
