Common rail in development for Himsen
Hyundai Heavy Industries engine & machinery division is developing a common rail system and an intelligent control system for its Himsen engine range. The development is party of a continual R&D programme on engine efficiency, driven by the potential for more stringent US EPA (or other regulatory body) air emission standards. Recently the company has developed its own selective catalytic reduction (SCR) system, which, it says, delivers more than 90% of NOx reduction efficiency with high reliability. Commercialisation of the SCR system has been tried through SCR durability test. The company is also researching and developing the potential of technology such as fuel water emulsification and in-cylinder water injection in order to reduce current NOx emissions by 30-50%.
