Choate Engineering pistons are designed with the factory problems in mind. As do all our products, these pistons help to solve issues with piston failures!
- The reentrant bowl design is used to increase the temperature in the bowl to lower hydrocarbons. The reverse flow area in the pocket of the piston creates a “hot spot” that can lead to piston failure. After the fatigue of the alloy, the exhaust gasses act as a cutting torch and start from here ending in a crack across the piston in the same axis as the wrist pin. Knowing this we machine and Delip the area causing these issues to relieve it from generating these hot spots, and shortening the dwell time of the reverse flow area.
