Product Name: Best Quality Diesel Cummins B Series Engine Cylinder Liner 3904166 Model NO.: cylinder liner 3904166 Type: Cylinder Material: Iron Technics: Casting Standard Component: Standard Component Certification: ISO9001 Brand: Cummins Engine Model: B Series Warranty: 6 Months Trademark: cummins Transport Package: Standard Export Package Specification: CE, ISO Origin: China Product Description Best quality diesel Cummins B series engine cylinder liner 3904166The diesel engine has the highest thermal efficiency (engine efficiency) of any practical internal or external combustion engine due to its very high expansion ratio and inherent lean burn which enables heat dissipation by the excess air. A small efficiency loss is also avoided compared to two-stroke non-direct-injection gasoline engines since unburned fuel is not present at valve overlap and therefore no fuel goes directly from the intake/injection to the exhaust. Low-speed diesel engines (as used in ships and other applications where overall engine weight is relatively unimportant) can have a thermal efficiency that exceeds 50%.Product namePart NumberEngine modelweight (kg)volume1piston3907163B1.215x15x20cm2piston39071561.215x15x20cm3piston39266311.215x15x20cm4piston39577951.215x15x20cm5piston39286731.215x15x20cm6piston3948465QSB1.515x15x20cm7piston39393981.515x15x20cm8piston3923165C215x15x20cm9piston3923537215x15x20cm10piston3925878215x15x20cm11piston3917707215x15x20cm12piston3929161215x15x20cm13piston3943367215x15x20cm14piston3992118215x15x20cm15piston3017348NT8554.515x15x20cm16piston30173494.515x15x20cm17piston30515554.515x15x20cm18piston30488084.515x15x20cm19piston30768114.515x15x20cm20piston3096680K5.515x15x20cm21piston30966815.515x15x20cm22piston30966825.515x15x20cm23piston30966835.515x15x20cm24piston30966855.515x15x20cm25piston49137955.515x15x20cm26cylinder liner3904166B1.215x15x25cm27cylinder liner3948095C/L515x15x25cm28cylinder liner4009220K191215x15x25cm29cylinder liner3007525K38 501215x15x25cm warranty6 monthsDeliveryBy sea, by air, by expressPackage1, Neutral Packing2, As customer requirementFutures1, More rugged and reliable2 , High torque output hence pulling power is high3 , Gears are tall4 , Fuel efficiency is high5, Service requirement is less frequent
