Design And Function: Releaser
- Pulley.
- Housing
- Springs
- Armature
A four stroke engine has two ignition pulses per crankshaft revolution. These give rise to a frequency that is forwarded through the crankshaft to the crankshaft's outer pulley. The releaser is used as a filter, with the function of isolating the inertia of the auxiliaries from the from engine's pulsations. Reduced irregularity in the pulley rotation extends the service life of the component parts such as drive belt, tensioner, etc. In addition, the spring force of the tensioner is reduced, which contributes to reduced fuel consumption.
