The lower spring plate, designated as H 27080, serves as the foundational support for valve springs in the Sulzer ASL25 diesel engine. It ensures the spring is correctly seated and evenly distributes load during compression and release cycles. Constructed from durable, wear-resistant materials, this plate helps maintain the precise function of the valve mechanism over long operational periods. Its role, though simple in appearance, is critical for the accurate timing and efficiency of the engine’s valvetrain system.
The intake exhaust valve with code number H 27076 plays a dual role in the Sulzer ASL25 engine by managing both the entry of fresh air and the expulsion of exhaust gases. This high-performance valve is designed for efficient airflow control and optimal combustion, which are vital for engine power output and fuel efficiency. Manufactured from heat-resistant materials, the valve endures extreme temperature variations and constant cycling. It is a key component in maintaining smooth engine operation and reducing emissions.
The clamping connection identified by code number H 27095 is a crucial fastening component within the Sulzer ASL25 diesel engine. Its primary function is to securely join different mechanical parts under high pressure and thermal load, ensuring structural stability and leak-proof operation. Designed to withstand vibrations and mechanical stress, the clamping connection is integral to the integrity of engine assemblies, especially in demanding marine and industrial environments. Regular inspection and proper torque application are essential for maintaining its reliability and performance.

As summer begins, energy experts are warning: Croatia could face a repeat of last year’s grid collapse. The previous blackout, which originated in Montenegro, revealed just how vulnerable the system becomes when extreme demand, outdated infrastructure, and misaligned investments converge. Based on recent indicators — the risk is unfortunately very real.
Last Year’s Blackout Was No Accident
The grid failure spread from Montenegro into Croatia until the system reached its breaking point. With growing demand — especially in summer — and aging infrastructure, similar events can easily happen again.
Quoted from the press:
Energy consultant Zdeslav Matić stated:
“Grid development has been neglected for the past 40 years while demand kept growing. If another collapse occurs, it will continue until we build a network that can handle it.”
Renewables: A Potential, but Also a Challenge
Renewables are not the cause of today’s issues, but they highlight the need for a flexible and resilient grid. Variability from solar and wind sources demands a system with strong storage and load-balancing capacity.
Quoted from the press:
“Investors are fast — the state is late. Infrastructure lags behind development, and regulators are behind with rulebooks,”
warns Dr. Robert Pašičko from the Geotechnical Faculty in Varaždin.
What Has Been Missed?
Neighboring countries’ grids (BiH, Montenegro, Serbia) are also underdeveloped. While Croatia is regionally better connected than the Iberian Peninsula, that doesn’t guarantee security.
Solutions Exist — and Are Already Available
How to increase system resilience?
Adriadiesel: Containerized Solutions for Grid Stability
Adriadiesel is developing modular battery containers (up to 1.5 MWh) using second-life EV batteries. These systems can:
Each container has its own cooling and safety system and can be rapidly deployed without additional infrastructure. Expansion of high-speed connection points near solar and wind farms is already underway.
Conclusion: Grid Stability Cannot Be Taken for Granted
With an increasingly complex system and a lack of investment, the question is not if, but when. A sustainable grid cannot be improvised — it requires strategic investment, skilled personnel, and political will.
“Burying our heads in the sand and relying on the market is not an option.”
If Croatia wants long-term energy stability, the time to act is now.

The mounting fixture identified by code number K 92161 provides the necessary support and alignment for fine regulating valves K 92165 and K 92166 in the Sulzer ZV40/48 engine. This mounting system ensures that the valves remain securely in place while allowing precise adjustments necessary for optimal fuel or fluid control. Designed to endure constant vibration and thermal expansion, the mounting ensures long-term operational stability. Its role is vital in systems where fine-tuned regulation is essential for performance and efficiency, and any misalignment or instability could compromise the engine's operational accuracy.
The sealing element identified by code number K 16105 is specifically designed to ensure airtight and fluid-tight connections between components K 16102 and K 16150 within the Sulzer ZV40/48 engine. Effective sealing is critical in high-pressure engine systems to prevent leaks of lubricants, fuels, or gases that could lead to performance issues or mechanical failure. Manufactured from heat- and chemical-resistant materials, this seal maintains its integrity under intense operational conditions. Regular inspection and timely replacement of this sealing component are vital for maintaining system efficiency and protecting surrounding parts from wear or contamination.
