CP-CARRILLO Product Catalog

DESIGN & ENGINEERING Custom pistons and rods are the backbone of any true hardcore racing engine and that’s where CP-Carrillo excels. Our Engineering department started off analyzing the competition, gathering industry data and decid- ing to make the highest level of custom pistons & rods, period. The heart and soul of our custom pistons & rods is built through our Engineering Department and its resources. This department is made up of several factors that push them ahead of the competition; Reverse Engineering, Design Experience and Flexibility, Analysis and R&D. As in racing, it takes a lot to be number one; here at CP-Carrillo we have it all and are number one in piston and rod design, enabling our customers to come in first on race day.

PISTON FEATURES

Reverse Engineering

Our Reverse Engineering encompasses: sample pistons, blueprints, chamber molds, a cylinder head, or 3D models supplied by a customer. We employ advanced scanning technology to reverse engineer any head or dome shape and incorporate 5 axis ma- chining capabilities to produce a perfect match for any application. All scanning and 3 dimensional designs are confidential and done in-house, making sure that you get the most accurate piston possible.

Design Flexibility

Design Flexibility is one of the most important things at CP-Carrillo. What we learn from our extensive OE involvement allows us to take piston designs to new levels and share that directly with our customers. Our vision for future designs entails all related components, designing the piston, rings, locks, wristpin and rod all around each other, ensuring you get the best piston-rod assembly the industry has to offer, a feature no other manufacture can claim.

Analysis

Analysis is the key to our designs. We utilize the leading pre and post-processor finite element analysis, while incorporating advanced nonlinear and thermal FEA capabilities. We can solve a wide variety of complex structural and thermal problems including cou- pled thermal-structural investigations while our software enables us access to meshing and CAD integration tools.

INTRODUCTION

Cam and Barrel

The Cam is the shape around the skirt of the piston and the barrel is the shape from under the oil ring to the bottom of the skirt. Extensive research and development has been done to find the optimum skirt shape for each piston. These shapes have been found to seal up cylinders and reduce harmonics in the bore better than ever before. Depending on the forging and application, different cam and barrel profiles are utilized for maximum performance. Having the correct cam and barrel on a part promotes the following:

1. 2. 3. 4. 5.

Tighter clearances

Less noise

Better ring seal

More power

Increased durability
