Sinotruk MC Series Engine
11L displacement, 360 hp
The high-pressure common-rail pump features a mature design and high injection pressure, ensuring excellent diesel atomization; the engine delivers strong low-end torque, preventing stalling during hill climbs or heavy-load starts.
Fuel lines are secured with metal clamps, and critical lines are encased in corrugated protective sleeves to prevent abrasion; the pump unit and connections are free of oil seepage, demonstrating excellent sealing integrity.
Finished with the original deep-blue factory paint offering superior rust and corrosion resistance; components appear brand new upon delivery, with neatly routed lines and hoses.
Fuel-Water Separator Assembly
Designed with a transparent separation bowl and fluid sight tube, allowing for clear visual inspection of water presence and oil clarity without disassembly, thereby preventing water from entering the combustion chamber.
The top-mounted manual valve requires no special tools; drivers can quickly unscrew it by the roadside to easily drain water and impurities from the bottom of the bowl.
The sight tube is made of transparent nylon/Teflon, offering high toughness and corrosion resistance; metal connections ensure a tight seal, maintaining transparency over the long term without aging or cracking.
Effectively extends the service life of the high-pressure fuel pump and fuel injectors, reducing the risk of major engine overhauls caused by fuel system issues.
Rear Axle Air Suspension
Superior Ride Comfort: Air bellows effectively absorb road shocks, reducing cargo damage rates and enhancing driver comfort during long-haul trips.
Adjustable Height: The control system allows for chassis height adjustment, facilitating quick coupling and uncoupling with trailer fifth wheels of varying heights.
Chassis Protection: Minimizes metal fatigue and deformation in the frame when switching between unladen and heavy-load states, protecting the driveshaft and rear axle components.
Compact Design: Air reservoirs are integrated with the air bellows; air lines are neatly routed and securely fastened with metal ties, making maintenance and servicing extremely convenient.
