<p>An internal combustion engine has a mechanical compression release including a cam, a cam follower, and a compression release member. The cam having a cam lobe and a base radius with a slot, and a compression release member disposed within the slot. The compression release member is substantially V-shaped and is comprised of a first portion, a second portion, and bridging portion. The first portion has an auxiliary cam surface that extends slightly beyond the base radius and the second portion has sufficient mass to function as a flyweight. The bridging portion is substantially U-shaped and connects the first and second portions. The compression release member pivots about a pivot pin, that is disposed within the curved portion of the bridging portion. As the cam rotates, centrifugal forces cause the compression release member to pivot and to disengage from the cam follower.</p> |
