Diesel engine cam system FlexValve

FlexValve is a compact, robust and efficient mechanical valve train system. It permits continuous variability of valve lift over a broad range, even allowing secondary opening of the valves, if desired. This gives a lot of flexibility to influence the gas exchange process and engine out exhaust gas temperature. In addition, FlexValve is modular, offering various modules to change the function of the valve train system without having to change the cylinder head design and manufacture. This makes FlexValve an ideal solution for diesel engines, including those for commercial vehicles, which are sold in markets with differing emission standards. FlexValve offers the following advantages for diesel engines: - faster warm up and improved after-treatment efficiency - improved transient EGR control and/ or faster T/C response thanks to secondary valve opening - variable effective compression ratio - adjustment of load and temperature for optimized combustion control - Compression release engine braking
