The turning gear operating at 3 x 440V is an essential component for the MAN L21/31 engine’s maintenance and safety. It allows controlled rotation of the engine during start-up and shutdown procedures, preventing shaft distortion and uneven wear. This gear ensures smooth engine positioning, facilitating inspection, servicing, and prolonging the engine’s operational life, especially in demanding industrial applications.
The cylinder head complete, combined with the fuel injection valves, forms a crucial assembly in the MAN L21/31 engine. The cylinder head seals the combustion chamber, housing the valves and injection system that ensure efficient fuel delivery and air flow. The fuel injection valves precisely meter fuel into the combustion chamber for optimal combustion, maximizing power output while minimizing emissions. This combination is vital for engine efficiency, performance, and longevity.
The locking ring identified by code K 72145 is used to secure the flexible rod K 72135 within the Sulzer ZV40/48 engine system. It holds the rod firmly in place, ensuring accurate alignment and preventing unintended movement during engine operation. This is particularly important in systems where mechanical stability and precision are critical, such as fuel or lubrication controls. Constructed to withstand mechanical stress and vibration, the locking ring supports both safety and reliability across extended engine service intervals.
The support with code number K 72303 is an essential structural component in the cylinder lubrication system of the Sulzer ZV40/48 diesel engine. It provides a secure mounting base for the lubrication delivery mechanism, ensuring that lubricating oil is evenly and accurately distributed to cylinder walls and piston rings. Proper cylinder lubrication is vital for minimizing wear, reducing friction, and prolonging engine life. This support not only ensures stability but also contributes to consistent engine performance and reduced maintenance requirements.
The packing component with code number K 73039 is specifically designed for use with part K 73034, the locking screw of the cooling water pump casing in the Sulzer ZV40/48 engine. This packing plays a crucial sealing role, ensuring that the connection remains watertight under varying thermal and pressure conditions. It helps prevent coolant leakage, which is essential for maintaining the integrity and efficiency of the engine's cooling system. Made from durable, high-resistance material, this packing ensures long-term performance and reliability in demanding marine environments.
The complete lubricating oil pump, also known as the cylinder lubricating pump, is vital in the MAN L21/31 engine for distributing lubricating oil to the cylinders and other moving parts. This pump maintains proper lubrication to reduce friction, prevent wear, and support smooth engine operation. Its reliable performance is key to extending engine life and ensuring consistent functionality under heavy-duty conditions.
The injection camshaft controls the precise timing and operation of the fuel injection system in the MAN L21/31 engine. This camshaft ensures that fuel is injected into the combustion chamber at the optimal moment for efficient combustion and power generation. Manufactured with high precision, the injection camshaft is essential for fuel economy, engine performance, and emission control.
The mounting of the double gearwheel is a critical assembly in the MAN L21/31 engine’s timing system. This component secures and supports the double gearwheel, which plays a key role in transmitting rotational motion between gears for precise synchronization of engine components. Proper installation and maintenance of this mounting ensure the reliable operation and longevity of the timing mechanism.
Dvostruki konusni stezni prsten, označen šifrom K 27503, ima ključnu ulogu u učvršćivanju sklopa usisnog ventila motora Sulzer ZV40/48. Konusni oblik omogućuje ravnomjernu raspodjelu sile oko stabljike ventila, čime se osigurava pouzdano i čvrsto brtvljenje pod visokim temperaturama i tlakovima. Konstrukcija u dva dijela omogućuje lakšu montažu i demontažu, što značajno olakšava održavanje. Ova komponenta je neophodna za osiguranje performansi motora, brtvenog učinka i dugotrajnosti rada.
The locking screw marked as K 73033 is a seemingly small but indispensable element in the secure fastening of the cooling water pump casing in the ZV40/48 engine. Designed to resist vibration and pressure fluctuations, this screw helps maintain a tight, leak-free seal around the pump housing. Precision manufacturing ensures it stays in place even during prolonged engine operation. By preventing coolant leakage and preserving pressure integrity, the locking screw contributes to the stability and efficiency of the engine’s cooling system.
