Abstract

본 발명은 엔진의 성능 및 내구성 등을 실제의 차량에 설치된 상태와 동일한 조건으로 시험할 수 있도록 팬 모터의 회전속도를 가변시키는 것이다.The present invention is to change the rotational speed of the fan motor so that the performance and durability of the engine, etc. can be tested under the same conditions as the state installed in the actual vehicle.

본 발명은 엔진(11)에 설치되어 엔진(11)의 구동에 따라 속도 신호를 발생하는 다이나모 메터(11A)의 출력 신호에 따라 팬 모터(12)의 회전속도를 가변시키는 것으로 다이나모 메터(11A)의 출력신호로 속도 제어부(13)가 엔진의 구동 속도를 판단하여 속도 제어신호를 발생하고 발생한 속도 제어신호에 따라 회전속도 가변부(14)가 팬 모터(14)의 회전속도를 가변시킴으로써 엔진을 실제의 차량에 설치된 상태와 동일한 조건으로 시험할 수 있다.The present invention is installed in the engine 11 to vary the rotational speed of the fan motor 12 in accordance with the output signal of the dynamometer (11A) that generates a speed signal in accordance with the drive of the engine 11 dynamometer (11A) The speed control unit 13 determines the driving speed of the engine with an output signal of the engine, and generates a speed control signal. The rotation speed variable unit 14 changes the speed of the fan motor 14 according to the generated speed control signal. Can be tested under the same conditions as in the actual vehicle installation.
