What special features does the TopCare cylinder have to help a cylinder break-in and wear over the life of the cylinder?

The Hard Fact is that the Continental goes the extra mile on each cylinder to produce a system that both retains oil and helps with cylinder break-in. The TopCare cylinder features a unique two-step cylinder wall honing system that first introduces deep oil retaining grooves in the cylinder wall, followed by a second stage that creates a plateau system which helps to quickly seat the piston rings during initial engine operation without eliminating the deeper scratches. Designed and tested by Continental Motors, the two-step hone process is 100% inspected by computer based tools to assure that every TopCare cylinder meets our exacting standards.

TCM has precise grinding equipment to create the desired size and shape of the bore and the desired choke in the very hard nitrided bore surface. With the shape established, the hone pattern is the next step. The two-stage hone process is done to create a hone pattern that breaks in quickly, but retains lubrication for long life.

How do you check the critical hone pattern?

Every TopCare cylinder provided is inspected at a computerized inspection station that provides an exceptional view of the hone pattern and calculates a number of characteristics.

This equipment permits process development and control far better than the "magic touch" technique and takes the mystery out of the process. Our hone pattern is better than any conventional hone pattern!
