SAFETY ENVIRONMENTAL Liebherr The new common rail fuel injection system developed by Liebherr is designed for use on diesel engines that have to comply with Tier 4F Stage IV emission regulations Since the beginning of 2012 this new fuel injection technology has been applied successfully to Liebherr engines that are required to satisfy Tier 4i Stage IIIB emission limits All configurations from four cylinder inline to 12 cylinder in V arrangement can use this system and from 2014 on Liebherr will make it available to other engine manufacturers as well for on and off highway applications in the medium and heavy duty categories and also for stationary engines Together with the new Liebherr engine control unit the engine management system that Liebherr has developed detects all of the relevant physical values relating to engine operation and uses them for optimal actuation of the fuel injection system The company says a wide range of functions and parameter determination ensures reliable engine performance at all operating points Scania Scania industrial engines manage Tier 4F Stage IV without a particulate filter With only EGR and SCR technology the installation is unaffected Scania developed systems for engine management and emission control are designed to ensure a blend of performance and operating economy Versions are available that meet all of todays emission steps including Stage II and IIIA Scanias long standing experience of EGR and SCR for trucks and buses has meant these developments could be applied to Scania industrial engines as well Clean and refined combustion technology means that the very stringent Tier 4F Stage IV regulations that apply from 2014 can be handled without the need for a particulate filter Scania uses the same modular engine platform for all steps in emission legislation Hence there is no need for global OEMs to redesign their equipment for Stage II III or IV markets Volvo John Bartz emission solutions manager for Volvo says the new generation of Volvo diesel engines featuring Volvo Advanced Combustion Technology V ACT has been engineered for non road applications and to meet the specific needs of each Volvo machine Tier 4 emission certifications require that the entire system of engine and any aftertreatment system be certified together Emission controls are no longer confined to the engine itself At Volvo Bartz says we will carefully evaluate all technology to access its fit in non road applications Volvo is a leading global manufacturer of engines for both on road and nonroad This positions us well to transfer our vast experiences and technologies already developed tested and productionized in the global on road sector and apply it to our non road development P Q If This Is Your World Is Your Filter Reliable Heavy Duty Lube Fuel Air Hydraulic Coolant and Cabin Air Filtration Designed for the Rigorous Challenges of the Mining World OTLINE s www luberfinermining com 2013 Luber finer by FRAM Filtration An ISO14001 and ISO TS16949 registered company 200 S 4th Street Albion IL 62806 1313 Hotline 800 882 0890 or 618 445 6011 22 PIT QUARRY May 2013 www pitandquarry com
