6 cylinder in line diesel engines include three great sorts with common model, intensified model left & right engines (Series G) and series B left & right engines. 6190 common engines remain the advantages of the original series 190 engines considering the special requirement of marine engine. Adapting new technology and new structure, it is obvious to improve the economy, reliability, assembling on boat and maintenance. In order to meet the requirements of inner river shipping and the main propulsion with two engines and two propellers, we develop the B6190 LEFT & RIGHT engines. Based on the successful experience of 601 engines, we also make modifications to G6190 to increase the power of single cylinder by 20%. G6190 engines, with high level main technical targets of similiar size engines, have become the ideal engines for fishing and shipping boats, and this series engines got scientific technology advanced award in province at the end of 2002.
Since these engines 6190, B6190 and G6190 taking into production, the market has become larger and larger year by year, the north to Peony River at Liaotung Peninsula, the south to ZhanJiang in GuangDong province. 6190 engines are wildly used for fishing, harbor boats, tugboats, transportation and other kinds of cargo boats. At present, there are about 3000 engines in the markets. In ChangJiang River area, these engines are well used as main propulsion for a lot of cargo boats and also medium & low power stations (350-450KW). Owning to good economy and reliability, this series engines, with high power, low consumption and easy maintenance, cater for the customers very much. Single engine, fire control pumping sets with single bearing, gearbox sets, marine gensets are well sold to a lot of countries and areas, such as TaiWan, Malaysia, Indonesia, Vietnam, Tunisia, Morocco, Mexico, Ecuador, Peru, Venezuvena, Brasil, Nigeria, Ghana, Tanzania, India, Thailand, etc
As users required, some models of engines could be modified to be operated with heavy diesel.
