Why Common Rail 2.2

Future fuels demand higher flexibility, while today’s engines must deliver reliability and low lifecycle effort. CR 2.2 (Common Rail 2.2 ) replaces multiple legacy designs with a single platform that supports current fuels and creates a clear path toward future injection technologies.

Built for today and tomorrow

CR 2.2 delivers state-of-the-art liquid fuel injection for today’s engines while transferring key design principles to future methanol and ammonia injection systems. It is a critical building block for the next generation of fuel injection equipment.
