VALVE TIMING WITH VARIABLE OVERLAP CONTROL

The development program as applied to a medium power engine has indicated a potential of 5% improvement in vehicle ECE fuel economy with a marginal reduction in vehicle performance. It is predicted that when applied to a high performance engine with its inherent higher fuel consumption, a further improvement in fuel economy of 4% would be attained. The vehicle development program now in progress will confirm the engine test bed data and quantify the vehicle driveability and refinement aspects.
