The clamping piece K 81184 is a precision-engineered fastening component used to secure support K 81260 within the heavy-duty structural assemblies of the Sulzer/Adriadiesel/Jugoturbina/Zgoda ZV40/48 engine. Designed to withstand continuous vibration, dynamic loading, and harsh operating conditions, this clamping piece ensures stable positioning of the support frame and prevents loosening or misalignment during engine operation. Its robust construction and exact fit enable reliable long-term anchoring of auxiliary components, contributing to improved structural integrity and dependable overall engine performance.
The fuel pump connections, code P51435-14, serve as the critical interfaces between the fuel supply lines and the high-pressure injection pump in the MAN L21/31 engine. Designed for precision alignment and leak-proof operation under high pressures, these connections ensure stable fuel delivery and reliable pump function. Their integrity is vital for maintaining injection efficiency and preventing pressure loss or air ingress, directly impacting engine performance, emissions, and long-term durability in both marine propulsion and auxiliary power systems.
The fuel oil arrangement, code P51430-28, comprises the integrated system of pipes, filters, valves, and sensors responsible for the preparation, distribution, and management of fuel oil within the MAN L21/31 engine. This carefully configured network ensures proper fuel conditioning—such as temperature control, filtration, and pressure regulation—before injection. By optimizing fuel quality and flow dynamics, the fuel oil arrangement enhances combustion stability, engine responsiveness, and operational safety, especially in variable-load marine environments and power generation facilities.
The fuel injection pipe, code P51404-18, is a high-pressure line that delivers fuel from the injection pump directly to the cylinder injectors in the MAN L21/31 engine. Engineered to withstand extreme pressure and thermal cycles, this pipe ensures consistent and precise fuel delivery, which is critical for achieving efficient combustion and optimal engine performance. Its robust construction and precision manufacturing minimize the risk of leaks and maintain injection timing, essential for meeting modern emission standards and fuel economy targets in marine and stationary power applications.
The threaded pin K 81192 is a precision-machined fastening element used to anchor and secure support K 81260 in the ZV40/48 engine’s mounting systems. Engineered for high tensile strength and resistance to vibration, this threaded pin maintains a stable connection even under demanding operational conditions. Its accurate threading ensures easy installation, secure engagement, and long-lasting structural integrity. Although small, K 81192 plays a critical role in keeping the support assembly firmly in place, contributing to reliable operation and reduced wear of engine components.
The clamping piece K 81261 is a robust fastening component designed to secure and stabilize support K 81260 within the structural assemblies of the ZV40/48 engine. Manufactured to endure heavy mechanical loads and constant vibration, this clamp ensures proper alignment and firm retention of the support structure, preventing unwanted movement or loosening during engine operation. Its durable construction and precise fit contribute to the long-term reliability of auxiliary mounts, enabling consistent performance of the equipment they carry and improving overall engine stability.
