CO., LTD.DAIHATSU DIESEL MFG. CO., LTD.Diesel Engines, Auxiliary / PropulsionDiesel engine, Auxiliary, Main Propulsion, Fuel consumptionWe have developed 6DE-18 and 6DE-23 as the environmentally friendly economical engines for energy saving, low maintenance cost and have a high potential for meeting stricter exhaust gas regulations in the future, of course IMO NOx Tier II compliant.6DE-18 : Bore 185mm, Output and speed 680kWm/720min-1 and 860kWm/900min-16DE-23 : Bore 230mm, Output and speed 1,200kWm/720min-1 and 1,500kWm/900min-1These engines realized the environmental harmony and high performance by long-held technologies of DAIHATSU DIESEL. Besides they have achieved top-class fuel efficiency by thorough weight-saving and optimized design.6DE-18 / 6DE-23INQUIRIES 16-11, Nihonbashi 1-Chome, Chuo-ku, Tokyo, 103-0027, JapanTel : +81-3-3279-0827 Fax : +81-3-3245-0359E-mail : katsunobu.ochiai@dhtd.co.jpDE28DF is 280mm bore x 390mm stroke. Their 6 and 8 cylinders engines cover the output range of 1.7-3.8MWe.Both dual fuel engines apply the common rail micro-pilot injection system, and can be use MDO, HFO and Natural gas as fuel. Based on the optimization of A/F-ratio and other many parameters on gas mode operation, these engines are applicable to IMO NOx Tier III regulation without any exhaust gas after-treatment, can also reduce CO2 of 23%, SOx/PM of over 99%.The safety concept is in accordance with IGF code. If a gas mode trip happens, the engine switches over from gas mode to diesel mode operation immediately without any fluctuation of the engine output and revolution.Dual fuel engine DE28DF
