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.
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.
The nut coded K 27209 is a small but essential fastening element in the fuel injection system of the ZV40/48 diesel engine. Specifically designed to secure the fuel injection valve in place, this nut ensures a tight and stable connection capable of withstanding extreme pressure and vibration during engine operation. Made from high-grade, corrosion-resistant steel, it maintains the structural integrity of the fuel delivery system and plays a critical role in preserving injection precision, combustion efficiency, and long-term engine reliability.
The spring identified by code K 27210 is a precision-calibrated component that regulates the opening pressure of the fuel injection valve in the ZV40/48 diesel engine. This spring is responsible for ensuring that fuel is injected into the combustion chamber at the exact moment and pressure required for optimal combustion. Its tension characteristics must remain consistent over thousands of cycles, resisting fatigue and deformation. As a vital part of the fuel system, this spring contributes directly to combustion efficiency, power output, and emission control.
The self-locking nut, code number K 27417, is specially designed for secure fastening of the spindle (K 27401) in the starting valve system of the ZV40/48 engine. Its self-locking feature prevents loosening due to vibrations or pressure fluctuations, thus maintaining the correct positioning and alignment of the starting valve. Made from high-grade materials with anti-corrosive properties, this nut plays a critical safety role, ensuring the reliability of engine starts over prolonged operational cycles.
The complete inlet valve, coded K 27500, is a fundamental component of the air intake system in the ZV40/48 diesel engine. This valve governs the flow of fresh air into the combustion chamber, opening at precisely timed intervals to ensure optimal fuel-air mixture and efficient combustion. Built to endure extreme thermal and mechanical stress, the complete assembly includes the valve spindle, guide, springs, and seating surfaces. Its flawless operation is key to maintaining engine power, fuel efficiency, and smooth running under both marine and industrial load conditions.
The piston ring coded K 27410 is designed specifically for the starting valve assembly, particularly for part K 27404. It provides a tight seal between the piston and valve housing, preventing air leakage during pressurized starts. Manufactured from high-performance materials, this ring resists deformation, wear, and thermal cycling. Its effectiveness is critical to maintaining the efficiency and responsiveness of the engine's pneumatic starting system.
