AIM: to investigate techniques for improving engine efficiency through reduced friction including optimum lubrication and adaptive/smart components.

Objectives:

• Identification of tribological measures having the highest potential to improve the engine efficiency
• Identification of the need for adaptive components of the engine and development of relevant specifications
• Development of engine components with reduced friction losses
• Development of adaptive components
• Demonstration of functionality and reliability by means of engine tests
• On line control of cylinder condition by optimum cylinder lubrication
