Power Cylinder System Friction and Weight Optimization in High Performance Gasoline Engines

An ultra-lightweight piston and conrod without small end bush, combined with a ring pack designed for minimized friction is analyzed and demonstrated as an optimized power cylinder system in a high performance gasoline engine. Component and system analysis for optimizing the design, materials used and design features are reviewed, along with durability, NVH and friction testing results. Results are compared to other benchmark power cylinder system components for weight, performance and value.
