The insert bush coded K 27107 plays a critical role in the precise and stable mounting of the fuel injection valve in the ZV40/48 diesel engine. It acts as an intermediary sleeve, ensuring proper alignment and seating of the injection valve within the cylinder head. Designed to absorb mechanical stress and prevent wear between metallic surfaces, this component contributes to long-term sealing integrity and consistent fuel delivery. Made from heat- and pressure-resistant materials, it supports the injector’s function under high thermal loads and guarantees reliable engine performance across long maintenance intervals.
Round steel bars, code EN43AE0090, serve as foundational raw materials in the production and repair of various MAN L21/31 engine parts. Known for their high tensile strength, uniform diameter, and machinability, these bars are transformed into essential engine components such as pins, shafts, and mounting elements. Their metallurgical reliability ensures they meet the demanding structural and thermal requirements of diesel engines operating under continuous load.
The spray-nozzle with code 11.01227-0017.A is engineered to provide critical cooling and lubrication to high-heat zones inside the MAN L21/31 engine, such as the piston undersides and cylinder walls. Operating under pressure, it ensures optimal oil atomization and precise fluid delivery, reducing wear and enhancing performance. This component is vital in maintaining thermal balance and extending the service life of engine internals in marine and industrial applications.
The spray nozzle for control drive, code 11.01213-0060-1.0, is a key precision component within the MAN L21/31 engine’s lubrication system. Specifically designed to deliver a fine, targeted stream of oil to the control drive mechanism, this nozzle helps reduce friction and regulate operating temperature. By ensuring reliable lubrication under variable load and speed conditions, it contributes significantly to the overall efficiency and longevity of the engine’s control systems.
The sealing element coded K 27054 is designed to provide an airtight and fluid-tight seal for handle K 27008 in the ZV40/48 diesel engine. This component prevents leakage of oil, fuel, or air around manually operated components such as valves or access ports. Engineered from durable elastomeric or composite sealing materials, it resists wear, temperature fluctuations, and chemical degradation. A reliable seal like K 27054 helps maintain internal pressure integrity, reduces maintenance needs, and protects the engine from contamination and performance loss.
The spring plate with code K 27205 is a vital component in the fuel injection valve assembly of the ZV40/48 engine. Positioned to support and stabilize the injector spring, it ensures correct tensioning and proper valve actuation. Its flat, robust design allows it to absorb repeated stress without deformation, maintaining consistent injection timing. The spring plate’s precision manufacturing contributes to balanced fuel delivery, smoother engine performance, and reduced emissions, making it indispensable in the injection system’s long-term operation.
