6th Aug. 2005 World first ‘RT-flex50 engine’ delivered.

The world first 6RT-flex50 engine was delivered to a South Korean shipyard after successful test operation at DU Works. This engine will be installed on first vessel of the six bulk carrier in series. The 6RT-flex50 engine was developed and designed for various types of vessels such as Handymax and Panamax bulk carriers, product tankers, feeder container carriers, medium-sized reefer container carriers, and so on. The RT-flex engine features electronic control system of reliable design based on the long experience in service to date. The unique feature of the RT-flex engine is the electronically controlled fuel injection and exhaust valve actuation made possible by the newly developed common rail system. Thanks to this unique system the RT-flex engine can achieve both low fuel consumption and smokeless/smooth operation with low NOX emission even at a very low engine speed.
The high reliability and operation performance of the engine were confirmed during the test operation for more than one month at DU Aioi works.
