Will SinterCast CGI be used for non-diesel (gasoline) engines?

The CGI market is beginning with diesel engines because of the need for stronger materials. Likewise, the application of CGI to gasoline engines will be driven by need. The automotive manufacturers will generally not make changes, especially those requiring increased cost, until there is a need for the change.

The three main opportunities for CGI in gasoline engines are:

  1. Upgrading an existing grey iron engine. For example, an OEM may want to increase a 1.8 litre engine to 2.0 litres and grey iron may not be strong enough to allow for reductions in the bore wall thickness or to support the increased mechanical loading. A change to CGI would be significantly less expensive than developing a new engine.
  2. Gasoline direct injection (GDI) engines, which may be embraced in the future to provide superior fuel economy and performance, have more severe loading and could potentially benefit from CGI. GDI is another opportunity for CGI.
  3. Small (<1.5 litre) gasoline engines must be very economical and, in many applications, may not be able to tolerate the higher cost associated with aluminium. In these cases, CGI would be a viable high-tech alternative.

The experience and confidence gained during the CGI diesel start-up will have an important influence on the decision to use CGI in gasoline applications. Successful CGI foundry production, machining, performance and image will give further confidence to the petrol engine decision makers.
