ABB, MTU Test VCM System Durability
Durability field-test results of ABB’s variable valve train system, Valve Control Management (VCM), have shown unprecedented success of the technology on an MTU high speed gas engine. The successful running of each VCM actuator for 7,000 hours on an engine is an important milestone for the forthcoming serialization of this technology. Typically, a durability test for serialization lasts around 5,000 hours for large engines. VCM is an electro-hydraulic valve train system for four-stroke gas and diesel engines…
ABB Power2 Completes Type Testing
ABB Turbocharging recently celebrated a milestone in its two stage turbocharging systems. Having equipped the first gas engine to enter commercial service with “Power2” two stage turbocharging equipment, ABB Turbocharging has now carried out Type Testing on a Power2 system in the presence of the Classification Societies on a hot gas test rig at its Technical Center in Baden, Switzerland. In this way, Power2 has passed a major milestone on its way to gaining Type Approval for use on 4-stroke, medium speed marine diesel engines. The Type Test of Power2 took place in early March 2011.
