About This Product

■FeaturesThe cam profile and valve timing of the intake and exhaust valves have a significant impact on the combustion efficiency of the engine. For this reason, the shape of the cam profile and timing settings are important development factors in engine development.

■Reducing costs and replacement workA&D provides hydraulic variable valve systems based on hydraulic technology accumulated through fatigue testing machines and 6-degree-of-freedom vibration exciters. Mechanical cams are no longer required, reducing the cost of cam prototyping and replacement work. It is possible to reproduce trapezoidal profiles and double-open profiles that are difficult to achieve with mechanical cams. You can also change the cam profile for each cycle.
