As an old shareholder in SinterCast, I am very pleased with the latest development of the company. At the Shareholder meeting in Katrineholm in 1997, it was stated that AVL was designing several CGI engines. Can you provide any update on this information, and the current status of these engines? Was AVL involved in the Ford-PSA 2.7 litre V6 engine?

AVL continues to be active in the design of CGI engines. The best evidence of this is the paper posted on our homepage on 30 July 2003 with the following quote from Dr Franz Zieher, Head of Design and Calculation of Commercial Powertrain Systems and Industrial Engines:-

“The engine of 2007 will have the same basic design as today’s units. There will be many improvements, such as more intelligent detail designs, and alternative materials will be used for the cylinder block and cylinder head. For example, compacted graphite iron (CGI) will replace grey cast iron. CGI is very strong and yet lightweight. It is already in use in some racing trucks, and DAF will be making their new generation of engines with it. AVL has examined materials in great depth, with a focus on current problems, identifying the necessary properties of CGI castings for application as a cylinder head and crankcase material.”

In particular, the statement “For example, compacted graphite iron (CGI) will replace grey cast iron”, clearly demonstrates the AVL view of the importance of CGI.

Although we are not able to disclose the details of any specific program, we do know that design consultants such as AVL, FEV, Lotus, Perkins and Ricardo have all been involved with CGI engine programs. In practice, it is common that an automotive OEM will work with more than one consultant on an engine program, possibly splitting the responsibility for activities such as design, modelling and testing.
