It is used as the ideal main machine for powering speedboats,cargo ships and fishery vessels and as the ancillary machine for 150-200kw GEN-SETS. Type Vertical, in-line, water-cooled and 4-stroke Intake way 9.839 The engine reliability is developed by adopting the European AVL technology and mechanical program in a deep &  broad sense,The overhaul period is more than 12 ,000 hours; Indexes such as the mean effective pressure,per liter power etc.are taking the lead at home;  The engine uses the top-class P type pump,low-inertia&small-orifice P type fuel injector and Honeywell new type turbocharger and so its specific fuel consumption is much better than other products the same power category at home; YuChai particular piston ring seal technology and valve oil seal technology reduce lubrication oil consumption by more than 50% compared with products of the same power category at home;  The engine uses the 42CrMo forged steel crankshaft under high-pressure ,and high-frequency quenched journals and rolled fillets to improve fatigue strength and wear resistance,Crankshaft front end is able to uotput the torque more than 900N.m; Displacement (L) Compression ratio 17.5 : 1 Turbo-charge, Intercooler Turbocharge  No.of cylinders-Bore×stroke mm 6 x 120 x 145 Continuous power kw(hp) One-hour power kw(hp) YICHEONG POWER Technical Data Sheet: YC6M series YC6M295C Model Features:  Its noise is much lowere by adopting the integral crankcase,rear-positioned gear chamber and the patented technoloty of spot-line meshing; Wet cylinder liner,one head for one cylinder to facilitate maintenance and service; Model YC6M220C Technical Parameters for YC6M 162 (220) 178.2 (242) 216 (295) 238 (325) 193.6(264) 219 (297) www.ycgenerator.com 1
