40 MARITIME REPORTER & ENGINEERING NEWS ? JANUARY 2013 16 DZC-1000-176 in V-con Þ guration, with an output of 3,600 kW at 1,000 rpm. KEEPING IT SIMPLE ABC engines were developed follow-ing the KIS (Keep It Simple) principle: a mechanical approach with a minimum number of components enabling quick and simple maintenance.Thus, ABC forgoes electronic compo- nents on the DX and DZ- series, eschew-ing such items as electronic governors or monitoring systems. All types feature mechanical instruments, e.g. Woodward Governor and analog measuring devic-es. ABC?s own development department concentrates on: improved fuel con-sumption, oil consumption reduction, power increase, use of bio fuels and the fulÞ llment of the required international exhaust legislations for maritime appli-cations. All engines hold certi Þ cates of the most important international classiÞ -cation societies, and genuine ABC parts and certiÞ ed factory service is available in 59 countries with 76 service stations keep the engines running. With the current DX and DZ range, ABC is offering solutions in the power range of 150-4,000 kW aimed primarily at the the marine coastal, Þ shing, dredg-ing, patrol-ships, tugboats and inland transportation vessels market. The en- gines are used in combination with al-ternators to generate electricity in power plants up to 30 MW and in powering locomotives with the DZ-engines In-line or V-con Þ guration.MEET THE NEW DL-SERIES ?This is a completely new engine de-signed from the bottom up,? said Tim Berckmoes, GM, ABC, during a special press conference.The new DL36 range expands ABC?s market to larger vessels such as ferries, coasters, offshore vessels, navy applica- tions, dredgers, and large tugboats, ves- sels that will be particularly affected by new edicts in designated emission con-trol areas (ECAs). The design enables shipowners to satisfy future, tougher emissions legislations without having to Þ t exhaust after-treatment plants. With the 6 and 8-cylinder In-Line DL36 (3.900 / 5,200 kW) and the soon to fol-low V-versions (up to 10,400 kW) the company will be able to supply all ma-jor shipyards with solutions for any type or size vessel. The DL36 range will also allow the company to be competitive in the 20-80 MW power plant range. With a bore x stroke of 365 x 420 mm (displacement of 43.9 l per cylinder), the DL36 will be set to deliver 650 kW/cylinder at 750 rpm with a bmep of only 24 bar, ensuring that the traditional ABC reliability and robustness is maintained. This 650 kW/cylinder makes the new DL-engine the highest power output in its segment.Introducing innovative technology such as Miller combustion process (ear- lier closure of the inlet valves causes expansion of the cylinder charge and a lower combustion temperature, which has beneÞ cial effect on NOx emission level), EGR, two-stage turbo-charging of company KBB and a radically opti-mized common rail system (rail pressure of up to 2.000 bar), the engine?s emis- sions are designed to meet the IMO/Tier III requirements without the need for any additional cost intensive exhaust-gas after-treatment systems, e.g. catalysts, while maintaining competitive fuel and oil consumption. The company antici- pates a speciÞ c fuel consumption rate of 180 g/kWh at 100% load. The high pres- sure common-rail and electronic control system has been developed in coopera-tion with company Heinzmann.For those applications not requiring IMO/Tier III, a full mechanical version will remain available. In addition, the engine is designed to offer a high degree of fuel ß exibility: it operates reliably on all kinds of marine fuels such as HFO, MDO, MGO, dual and bio-fuels. All these factors make the DL-series ideal for ships needing a clean yet efÞ cient form of propulsion.,The 6- and 8-cylin-der in-line engines will focus mainly on the marine market while the V-engines (12 and 16 cylinders) will penetrate also the large generator set application to be found in thermal power plants as the 16DV36 will produce over 10 MW. With the design and development of this new engine family, ABC con Þ rms the position as a major player on the me-dium speed engine market.COMPONENTS AND SYSTEMS The one-piece crankcase is made of nodular cast iron. Sidewalls with large crankcase doors allow easier access into the engine. The hanging bearing block are hydraulically and also transverse uptight. Thus, a very high torsional stiff- ness is ensured. A special feature is the modular cyl- inder design unit, consisting of: cylin-der head with four valves (two inlet and two outlet), cooling jacket, liner, conrod axle, piston, pin and rings. The complete unit is pre-assembled on a workbench, then mounted into the crankcase. Thus, the repair or assembly time can be sub-stantially reduced. This is particularly advantageous in case of a necessary re-pair. According to ABC the 6-cylinder engine will be available for shipment in the second half of 2013 followed by the 8-cylinder in 2014. Further develop-ment steps are: develop-ment of the 12 and 16DV36 engine range and also the ex-isting DZ range will be developed to fulÞ ll IMO III. www.abcdiesel.be PROPULSIONLeftThe newly developed DL-series comes as a 6 and 8-cylinder in-line version and a 12 and 16-cylinder v-type conÞ guration delivering 650 kW per cylinder. RightÒThis is a completely new engine designed from the bottom up,Ó said Tim Berckmoe, GM, ABC.A special fea-ture is the mod- ular cylinder design unit con-sisting out of: cylinder head with valves, cooling jacket, liner, conrod axle, piston, pin and rings.
