15 DESIGN AND ANALYSIS HOW TO USE THIS CATALOG This JE Pro Seal Ring catalog has been divided into three different sections for ease of reference and convenience. The three sections are separated in the following manner: Rings Listed by Series (pages 19-31) a legend has been provided on page 18 along with an accompanying performance matrix grid to assist you in determining the appropriate ring for your application. This section also features a complete breakdown of the ring set numbers into individual top, second and oil ring part numbers (except sport compact and motorcycle rings which are sold in sets only). Rings Listed by Axial Height (pages 33-37) In this section all JE Pro Seal ring sets are sorted by axial height then by application type. Domestic automotive rings are listed first, Import automotive second followed lastly by motorcycle ring sets. This listing is for ring sets only. Rings Listed by Bore Size (pages 41-45) This section contains all JE Pro Seal ring sets including single, four, six and eight cylinder packages in order of bore size. Once again a separate grid has been provided for large and small bore motorcycle ring packages. This listing is also for ring set only. TENSION MATRIX Ring tension is tangential and measured in pounds. The tension matrix is a chart that can show you how oil ring tensions are classified at JE Pistons. To use the matrix, first find the bore size for your application in the left most column, next line up your bore size with the correct axial height. Based on the tension ranges provided you can determine which ring set you need to order. 1 65 129 Pressure (B ars) RESULTS ANIMATION OF THE INSTANTANEOUS GAS PRESSURE DISTRIBUTION RING PROPERTY PISTON DESIGN ANALYSIS Determining how well a ring will function on a particular piston design is crucial to optimizing the horsepower output of your engine. JE uses Ricardo RingPak, the most advanced ring analysis and simulation software available, to simulate ring, piston, and cylinder wall interaction as a system. The software creates models of friction, wear, lubrication, blowby, and oil consumption within this system and allows JE to analyze in great detail both individual ring performance and overall piston design. Once the piston ring and land information is entered, animated results of such phenomena as gas pressure distribution and lubrication conditions are displayed. The careful analysis of these results can be used to properly select your rings to reduce excessive oil consumption (which may lead to detonation), blowby, and horsepower robbing friction. JE utilizes this new technology to achieve optimal ring performance and to further enhance our piston designs by using specially developed ring characteristics.
