4.7.6 Flywheel
The flywheel is a carefully balanced cast iron disc. In addition to ensuring uniform rotation of the crankshaft, the flywheel after unwinding helps overcoming the compression resistance inside the cylinders while starting the engine. The flywheel, due to the stored energy obtained during rotation, also provides the engine with the ability to overcome short-term overloads, for example, when starting a car, etc. Schematically, the flywheel is clearly visible in Figure 4.1 of this chapter.
The flywheel is bolted to the crankshaft flange. A gear ring is fixed for starting the engine from the starter on the rim of the flywheel. Reference marks are applied for determining the TDC of the piston of the first cylinder and for installing the ignition.
