The flywheel of a car is essential. Do you know what it does?

The disc component with large moment of inertia of engine flywheel plays the role of energy storage. The piston stroke works once. Only the working stroke is effective, and all three strokes of exhaust, intake and compression are consumed. The output torque of crankshaft changes periodically, and the speed of crankshaft is also unstable. In order to improve this situation, a flywheel is installed at the rear end of the crankshaft. Flywheel effect If you want to turn a stationary flywheel, you need a lot of force at first, and it is very tiring to push it around repeatedly, but the efforts of a circle are not in vain, and the flywheel turns faster and faster. When the critical point is reached, the gravity and propulsion of the flywheel become part of the propulsion. No more effort is needed at this point.

Connect the engine and the automobile transmission system through the clutch installed on the flywheel. Save part of the energy of the engine working stroke, overcome the resistance of other strokes, and make the crankshaft rotate evenly. Equipped with a gear combined with the starter, the engine is easy to start. You will find it difficult to start the engine. Because the start of the engine depends on many parts. Engine flywheel not only stores energy for the engine, but also helps the engine to start faster, so the importance of flywheel to the engine is self-evident. If the output torque of the crankshaft changes and the crankshaft speed is unstable, the situation can be improved after installing the flywheel. Centrifugal force produced by unbalanced mass during rotation will cause engine vibration or abnormal noise, and accelerate the wear of main bearing.

Flywheel gear ring and flywheel are important accessories of automobile engine. The rigid connection between flywheel and crankshaft can be used as the check of engine timing mark, and the inertia of flywheel rotation can be used to ensure the smooth operation of the engine in four working cycles. When the engine is started, the motor starts running, and the pinion of the motor meshes with the gear ring around the flywheel. Flywheel is a relatively large cast iron inertia disk, which can store energy, provide the demand of non-working stroke, and ensure the uniformity of inertia rotation and output torque when the whole curved connecting rod structure spans upstream and downstream. Through the inertia force of its own rotation, it is helpful to overcome the compression resistance of the cylinder when starting and keep the engine running continuously when it is overloaded for a short time. The flywheel of a multi-cylinder engine should be balanced with the crankshaft.

Flywheel is a passive component used to start the motor. When the car is running, the friction surface of the flywheel contacts the clutch plate of the clutch and transmits the power to the gearbox. When the driver steps on the clutch pedal, the clutch plate leaves the flywheel and the power transmission is interrupted. After leaving the pedal, when the clutch plate contacts the flywheel, the power transmission resumes. A flywheel is actually a disk. It works along the engine. The function of engine flywheel can not only store the energy and inertia outside the engine work, but also reduce the speed fluctuation when the engine works. As long as the flywheel releases energy. The engine flywheel is installed on the crankshaft rear end device. In order to improve the engine piston stroke, exhaust, intake and compression all need electricity.
