Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engines, and more particularly to a silicone oil shock absorber capable of synchronously monitoring dual speed and position signals. Background Art
[0002] The engine signal panel's primary function is to provide critical positional information necessary for engine operation, ensuring the coordinated functioning of all engine components. The signal panel, through its phase angle design and precise control, plays a crucial role in the coordinated operation of each engine cylinder. The signal panel provides signals to the tachometer sensor, which in turn transmits them to the ECU. The ECU uses these signals to control fuel injection and ignition, ensuring efficient and smooth engine operation.
[0003] Specifically, the functions of the signal disk include: 1. Controlling the switch of the engine. The signal disk is equivalent to controlling the switch of the engine. The design and precise control of its phase angle are crucial to the operation of the engine. 2. Providing the crankshaft position. The signal disk accurately determines the position of the crankshaft and works with the camshaft position sensor to determine the basic ignition timing and ensure the accuracy of the ignition time. 3. Detecting the crankshaft speed and angle of the engine. The signal wheel is designed as a wheel with many tooth segments. When the signal wheel rotates past the sensor, it generates an AC voltage whose frequency changes with the speed. 4. Controlling the engine ignition timing. By providing crankshaft position information, the signal disk and the camshaft position sensor jointly ensure the accuracy of the ignition time, thereby achieving smooth and efficient operation. In summary, the engine signal disk plays a vital role in the operation of the engine. By providing precise position information and control signals, it ensures the coordinated operation of various engine components, thereby achieving efficient and smooth operation.
