The complete fuel valve assembly H 27200 is a precision-engineered injection component responsible for delivering and atomizing fuel into the combustion chamber of the Sulzer ASL25 engine. Designed for high-pressure operation and precise flow control, this valve ensures optimal fuel distribution, efficient combustion, and reduced emissions. Manufactured with high-grade materials and tight tolerances, H 27200 maintains consistent injection performance under extreme thermal and mechanical loads, making it essential for stable power output, fuel efficiency, and long service life in demanding marine and industrial environments.
The internal valve spring H 27092 is a critical dynamic component of the Sulzer ASL25 valve train, designed to maintain precise valve control under high engine speeds and continuous thermal stress. Installed within the valve assembly, this spring ensures consistent closing force and accurate valve timing throughout the engine cycle. Engineered for exceptional fatigue resistance and dimensional stability, H 27092 performs reliably under repeated compression and elevated operating temperatures, directly supporting combustion efficiency, reduced valve wear, and long-term operational stability of the engine.
The guide bearing cap, code 11.01254-0169.A, provides axial guidance and positional stability for the crankshaft in the MAN L21/31 engine. By maintaining accurate alignment under fluctuating loads and thermal expansion, it helps control crankshaft movement and reduces mechanical wear. Its precision construction supports smooth engine operation, protects critical rotating components, and contributes significantly to the overall reliability and service life of the engine under demanding operating conditions.
The main bearing cap, code 11.01254-0168.A, is a critical load-bearing element in the MAN L21/31 engine, securing the crankshaft bearings firmly within the crankcase. Designed to withstand extreme cyclic loads and maintain precise bearing alignment, it plays a vital role in minimizing vibration and ensuring smooth crankshaft rotation. Precision-machined and manufactured from high-strength materials, this component directly influences engine durability, efficiency, and long-term operational stability.
The cylinder crankcase, code 11.01203-1642-1.T, is the core structural housing of the MAN L21/31 engine, supporting the crankshaft, main bearings, and cylinder assemblies while absorbing the immense mechanical forces generated during combustion. Engineered for high rigidity and vibration damping, this heavy-duty component ensures precise alignment of all rotating parts and provides the foundation for stable, low-noise engine operation. Its robust design is essential for long service life and reliable performance in continuous marine propulsion and industrial power generation environments.
The pressure rod H 27216 is a high-strength mechanical transmission component used in the valve actuation system of the Sulzer ASL25 engine, transferring motion from the camshaft mechanism to the valve assembly. Manufactured for exceptional rigidity, straightness, and surface durability, the pressure rod ensures accurate motion control and consistent valve operation under extreme cyclic loading. By maintaining precise geometry and minimizing deflection, H 27216 helps preserve correct valve timing, reduce vibration, and support the overall efficiency and durability of the engine’s valve train system.
