Valve Train parts Design and Test Ability

R&D

1. 3D Modeling For Rocker Arm

2. Applications of customer-specific material

CAD system in drawing, and we can also ensure our design by computer simulation analysis.Cheong Bo has test and measuring equipment where the products are constantly tested and improved.

3. Development of EGR valve

This Exhaust Gas Recirculation system is fitted to reduce NOx emissions, The EGR valve is send some of the exhaust gas back into the intake manifold. The recycled exhaust gas is mixed with the fresh fuel.

By sending some of the exhaust gas back to the cylinders, we can lower the combustion chamber temperature, Lower the chamber temperature lowers the amount of oxides of nitrogen produced. Our R&D center is developing the EGR valve parts, Base, Pintle, Valve seat, etc.
