The weld-on piece identified by code number K 81183 is an essential fabrication component used in assembling or repairing the exhaust piping of the ZV40/48 diesel engine. Designed for strong, leak-proof connections, this part is welded directly onto exhaust system sections to ensure durability and optimal flow of exhaust gases. Its robust construction withstands high temperatures and corrosive gases, making it ideal for marine and industrial engine environments. By enabling precise customization of the exhaust path, it supports both efficiency and compliance with emissions standards.
The expansion bolt with code number K 34127 is a specialized fastener used in securing the upper part of the piston in the Adriadiesel/Jugoturbina/Zgoda/Sulzer ZV40/48 diesel engine. Designed to endure high thermal loads, this bolt compensates for expansion and contraction during engine operation, maintaining consistent tension and alignment. Its ability to flex slightly under heat ensures structural integrity and prevents stress fractures in the piston assembly. This precision-engineered bolt plays a critical role in extending piston life and ensuring reliable engine performance under extreme conditions.
The rubber plate identified with code number H 87616 serves as a versatile insulating and cushioning element within the ASL25 diesel engine system. Typically used between structural components, it absorbs vibrations, prevents direct metal-to-metal contact, and helps maintain alignment during engine operation. Its durable and flexible material resists chemical exposure and mechanical stress, making it ideal for use in harsh engine environments. This seemingly simple component plays an essential role in reducing wear and enhancing overall operational stability.
The spiral seal bearing code H 81153 is engineered to offer advanced sealing performance in rotating or reciprocating engine parts of the ASL25 diesel engine. Its spiral geometry increases surface contact and resilience against pressure fluctuations and mechanical wear. This seal is especially suited for high-speed or high-temperature environments where traditional seals might degrade quickly. By maintaining fluid integrity and reducing the risk of leakage, the spiral seal contributes to longer engine lifespan and minimized maintenance needs.
The O-ring with code number H 82514 is a fundamental sealing component in the ASL25 diesel engine from Adriadiesel/Jugoturbina/Zgoda/Sulzer. Designed to ensure leak-proof connections between engine components, this ring-shaped rubber element is crucial in preventing the escape of fluids or gases under pressure. Its elastic structure allows it to adapt tightly between metal surfaces, maintaining a secure seal even under thermal expansion or vibration. The O-ring is vital for engine efficiency and safety, especially in high-pressure fuel, oil, or air systems.
How much did the Iberian blackout really cost – and what could have been done with that money

€1.6 billion in damages – in Spain alone
According to preliminary estimates from the Spanish employers’ association CEOE, the damage caused by the recent massive power outage in Spain is at least €1.6 billion.
This includes:
What could have been done with that money?
The question arises naturally:
Could the damage have been prevented by smart investment in grid resilience – specifically, in battery systems?
The answer is: yes, many times over.
How much does a serious battery system for grid stabilization cost?
Adriadiesel is developing containerized battery power plants based on second-life EV batteries.
With €1.6 billion, it would be possible to build:
Not just a cost — but an investment
Battery systems are not passive costs. They:
Time for a new approach to grid security
Instead of recording billions in damages every few years, the question should be reversed:
Why not invest €100 million in advance – to avoid €1.6 billion in losses later?
Decentralized battery systems:
Conclusion
The April 2025 blackout cost as much as a complete national battery defense — yet nothing was built.
It’s time Europe — especially the Iberian Peninsula — stopped relying on luck and started investing in technically proven, economically viable, and readily available solutions.
Adriadiesel already offers ready-to-deploy modules today.
