motorcycles of today are the true marvels of engineering basic model of inner parts of a tip cycle is shown here we will explain the basic function of each of these parts in a motorcycle let's begin from how a motorcycle engine starts all motorcycles have either a Kickstarter or a self-starter or both starter mechanism is simple yet interesting as the kickstarter livre is descended a helical spline forces the gear to slide and engage with a freewheeling gear on the main shaft as the leaver is descended further the gear spins on its axis and transfer the power to the clutch Hub the clutch Hub transfers the power to the crankshaft and eventually to the engine battery powered motor provides initial spin to the engine once the engine is started the starter motor has to be disengaged from the crankshaft to prevent damage due to excessive speed achieved by using a one-way clutch shown here is it a roller type one-way clutch it has an odor race and an inner race with small rollers as the starter motor spins the outer race in One Direction the rollers get trapped between the surfaces and the power is transferred to the inner race and us to the crankshaft what's the NRA start spinning faster than the outer race released causing the interface to spin like every four-stroke gasoline engine motorcycle engines require a source of ignition to ignite the air-fuel mixture for powerstrokes plug is used for this purpose the spark plug wires voltage in excess of 20,000 volts to fire properly in this particular model of the voltage is obtained from the stator of the motorcycle although a 12 volt battery may be used for the same purpose the stator is a stationary coil of wires the flywheel of a motorcycle has a set of permanent magnets which revolves around the stator and produces alternating current in the coils each output from the stator has different purposes as shown here the output for the ignition purpose is received from the Exciter coil coil has a denser winding of thinner wire than the other coils to produce higher voltage for the ignition which is supplied to an electrical known as the capacitive discharge ignition or CDI unit for an AC CDI is shown here the primary function of the CDI unit is to store electric charge and dump the store charge when required a capacitor inside the CDI unit stores the electric charge another component known as a pick-up coil tells the CDI unit when to dump this charge the pickup coil has a small magnet with a coil of wire around it the flywheel has a small Extrusion on its outer surface in approaches and passes the pickup coil a small voltage is developed in the coil does voltage is applied to the CDI unit which closes and electronics which known as a silicon controlled rectifier or scr dump all the charge when the capacitor through the output of the CDI unit to increase the voltage further and ignition coil is used the ignition coil is a Step up Transformer which increases voltage up to 200 times the input voltage which is sufficient to fire the spark plug several other factors contribute to the continuous operation of the engine child are controlled by using a timing chain as shown as long as the engine is running the crankshaft rotates and transfers power to the other components for proper operation single-cylinder engines generally use a counterbalance to reduce the vibration caused by unbalanced forces the clutch helps and smooth transfer of power from the crankshaft to the transmission system the transmission system helps in altering the speed and torque as per our requirement
