Variable Cam and Variable Valve Timing Technology
Variable Cam Timing (VCT) and Variable Valve Timing (VVT) are established technical strategies for optimizing engine performance, increasing fuel efficiency, and reducing emissions. This course covers the basic theory and operation of both VCT and VVT including their differences, modern approaches to implementing those systems, and their benefits and practical results.
Learning Objectives
By completing this course, you will be able to identify, recognize or articulate:
- General theory and potential system benefit of varying valve timing
- Difference between Variable Cam Timing (VCT) and Variable Valve Timing (VVT)
- Historical mechanisms to implement VCT and VVT systems
- Modern approaches to VCT and VVT systems
- Understand the mechanism by which VCT and VVT can improve system performance
- Contribution VCT and VVT can make to the overall system operation in a modern internal combustion engine
Who Should Attend
The intended audience for this course is powertrain engineers, component suppliers, vehicle platform powertrain development specialists, and those involved in the application, design and discussion of engines.
