Outline of Product
High-Speed Valve Lift Control
This engine development tool enables high-speed valve lift control by adopting a highly responsive hydraulic actuator.
Feature
- Contributes to the Development of Advanced Engines
- Capable of developing advanced engines with features such as variable valve lift timing, combined cycle (proper use in multi-cycle load ranges such as HCCI, etc.), a next-generation valve drive system, etc.
- Improves the Level of Optimization
- Multiple engines can be operated by changing the valve lift patterns in the same setup to enable optimization development within short periods for small budgets.
- Shortens Development Periods
- The cost and period for trial manufacturing are significantly reduced by eliminating the need to change the cam setup.
Application Items
- Diesel engine (single cylinder, multi-cylinder)
- Gasoline engine
