The guide piece with code number K 27403 plays a crucial role in the precise operation of the starting valve in the Sulzer ZV40/48 diesel engine. It ensures accurate alignment and stable movement of internal components within the valve mechanism, contributing to reliable air delivery during the engine's startup phase. Designed for durability and precision, this component must endure high-pressure conditions and mechanical stress. Its proper function is vital to maintaining the integrity and performance of the starting system, which is essential for smooth and safe engine ignition in marine and industrial applications.
The intake valve seat with code H 27155 is an essential part of the cylinder head assembly in the ASL25 engine. It forms the sealing surface for the intake valve, ensuring airtight closure and efficient air intake into the combustion chamber. Manufactured from heat- and wear-resistant materials, this component withstands high temperatures and repeated impact, maintaining its shape and functionality over time. A properly fitted valve seat is crucial for preserving engine compression, improving fuel efficiency, and supporting smooth combustion cycles.
The bearing cushion for the column axle-half, marked with code H 12020, plays a crucial role in supporting rotational movement within the ASL25 engine. Positioned strategically to reduce vibration and absorb loads, this cushion ensures smooth operation and protects the shaft from wear. Its precise design allows for balanced pressure distribution and long-lasting performance even under heavy-duty conditions. As a key component in the bearing system, it significantly contributes to the overall mechanical stability and efficiency of the engine.
The cylinder cover bolt with code H 11113 is a fundamental fastener in the ASL25 diesel engine, responsible for securely fastening the cylinder head to the engine block. Operating under extreme pressure and thermal conditions, this bolt must provide a reliable and durable seal to maintain compression and prevent leaks. Precision-engineered and made of high-strength material, it is designed to resist stretching and fatigue over prolonged engine use. Regular inspection and proper torque application are vital to ensure the engine’s operational integrity and performance.
The upper spring plate, designated as K 27501, is part of the inlet valve assembly in the ZV40/48 diesel engine. Positioned at the top of the valve spring, it evenly distributes the spring force and helps maintain correct alignment of the inlet valve during operation. This plate must withstand high cyclical loads and elevated temperatures, making material strength and structural integrity crucial. A well-functioning upper spring plate ensures reliable valve movement, which is vital for efficient air intake and overall engine breathing performance.
The piston with code K 27404 is an integral part of the starting valve mechanism in the ZV40/48 engine. It plays a central role in regulating the airflow during the start-up sequence, moving within the valve body to open or close the passage for compressed air. This piston must be machined with exact tolerances to ensure airtight operation and swift response under pressure. Its condition significantly influences the performance of the entire starting system, and regular inspection is critical to prevent starting failures.
